(n.) A routing technique in which intermediate nodes wait until they have received the whole of a message before forwarding any of it. Packet switching often requires a large amount of buffer space, and contention for access to this space can lead to deadlock. See also virtual cut-through, wormhole routing.
A switching system that uses a physical communications connection only long enough to transit a data message; data messages are disassembled into packets and reassembled at the receiving end of the communication link; packets may travel over many diverse communications links to get to the common endpoint. This is most often contrasted with circuit switching in data communications, where all data messages transmitted during a session are transmitted over the same path for the duration of the session. See also Circuit Switching.
Communications technique that breaks down messages into smaller units called packets, which are individually addressed and routed through a network. The network link is occupied only during packet transmission.
A technique for transmitting data in which the data is subdivided into packets by a PAD. Each packet carries the address of its destination and its sequencing information. Packets from many users are interleaved on a single communications channel. Defined by ITU (ex-CCITT) X.25.
A method used to move data around on the Internet. In packet switching, all the data coming out of a machine is "chunked;" each "chunk" has the address of where it came from and where it is going. This optimizes the number of computers able to transmit data over a single line.
This is the process of subdividing data into packets, allowing for easier transmission of the data. The individual packets are then sent, often following differing routes to their destination. After they have all arrived, they are recompiled into the original message. X.25 is the international standard.
A technique in which a message is broken into smaller units called packets, which may be individually addressed and routed through the network, possibly using several different routes. The receiving-end node ascertains that all packets are received and in the proper sequence before forwarding the complete message to the addressee.
A type of data transmission in which data is divided into packets, each of which has a destination address. Each packet is then routed across a network in an optimal fashion. An addressed packet may travel a different route than packets related to it. Packet sequence numbers are used at the destination node to reassemble related packets.
an efficient method for breaking down and handling high-volume traffic in a network; a transmission technique that segments and routes information into discrete units; packet switching allows for effi
The process of sending packets through the network, allowing re-routing if a particular network link fails.
Packet-switching permits the transfer of data that is broken into small data packets by Transmission Control Protocol (TCP). Each data packet is sent individually and even along different routes to a specified Internet Protocol (IP) address where it is reassembled. This permits the same pathways to be used by multiple users simultaneously. In contrast, circuit-switching, the method used in Plain Old Telephone Service (POTS), requires a dedicated connection for the duration of data transfer.
A data communications technique in which data is transmitted by means of addressed packets and a transmission channel is occupied for the duration of transmission of the packet only. The channel is then available for use by packets being transferred between different data terminal equipment. A data transmission method, using packets, whereby a channel is occupied only for the duration of transmission of the packet. The packet switch sends the different packets from different data conversations along the best route available in any particular order. At the other end, the packets are reassembled to form the original message which is the sent to the receiving computer. Because packets need not be sent in a particular order, and because they can go any route as long as they reach their destination, packet switching networks can choose the most efficient rout and send the most efficient number of packets down the route before switching to another route to send more packets. The other advantage of packet switching is the unified format that every message is moulded into.
As opposed to circuit switching where a circuit is kept open for communication, packet switching is the system whereby data is broken up into packets and sent by different routes between computers thus freeing the network when no data has to be sent.
Switching technology characterized by switching individual message units ( PDU s) consisting of a discrete unit of information. Compare with circuit switching.
A packet is a chunk of information sent over a network. Packet-switching is the process by which a carrier breaks up data into these chunks or packets. Each packet contains the address of origin, the address of its destination, and information about how to reunite with other related packets. This process allows packets from many different locations to co-mingle on the same lines and be sorted and directed to different routes by special machines along the way
Packet switching is how information is moved around the Internet. A packet is a certain amount of information, a message or a fragment of a message,which is routed from host to host in the most expedient possible manner (the expediency is determined by an algorithm. This means that messages sent between the same two Internet accounts might not follow the same path each time.
A communications paradigm in which packets (messages or fragments of messages) are individually routed between nodes, with no previously established communication path. The internet is a packet switched network. It is also called connectionless and is the opposite of circuit switched or connection-oriented networking. VoIP voice packets are an example of packet switching. (source)
A means for transmitting data messages by dividing the message into blocks or packets of standard length. Each packet has the destination address and other control information coded into it.
A method of transferring data in a network where individual packets are accepted by the network and delivered to the prescribed destination. Packets can be distributed in any order because the control data sent at the beginning of the transmission ensures they are interpreted in the correct sequence once received. Because each packet carries its own instructions, it can use any route to reach its destination.
Data transfer mechanism in which data is disassembled into small pieces, called packets, before transmission. Each packet consists of header and payload. Header contains source and destination addresses and control bits, while payload contains a piece of data. At the receiving end, all packets are assembled into the original data based on header information. Unlike circuit-switching, packet switching lets multiple users share a transmission channel resulting in better bandwidth utilization. See picture. Compare with circuit switching and cell switching.
This is a method of transmitting data, organized in packets, through a network.
A wide area communications technique in which data is packeted for transmission over a shared data network rather than over dedicated lines. Packet switching differs from circuit switching in that is uses virtual circuits, i.e. it is made up of bandwidth allocated on demand from a network of shared circuits.
Networking method in which nodes share bandwidth with each other by sending packets. Compare with circuit switching and message switching. See also PSN (packet-switched network).
A data transmission process, which utilizes addresses packets, in which a channel is occupied only for the duration of transmission of the packet. Note: In certain data communication networks the data may be formatted into a packet or they may be divided and then formatted into a number of packets (either by the data terminal equipment or by equipment within the network) for transmission and multiplexing purposes. See also: multiplexing.
A data communications technique that packages data into groups called packets for transmission across phone company lines. In a packet-switched network, the groups or frames of data each have a source and destination address to facilitate correct routing through the network. Packet switching is the data communications equivalent of the postal system: Each letter or packet is sent and returned on the basis of the addresses on the packet. Packet switching transmission rates are usually low-speed circuits that operate at 1200 bps to 56 Kbps.
The method used to move data on the Internet. In a packet switching network, all the data coming from a machine is broken up into chunks. Each chunk includes the addresses of both the origin and the destination. This enables chunks of data from many different sources to intermingle on the same lines and be sorted and directed along different routes. In this way, many people can use the same lines at the same time. A second advantage of packet-switching networks is that since packets can take alternative routes through the network, data transmission can easily be maintained if parts of the network are damaged. See also router.
As opposed to circuit switching. A digital switching technology which massively improves the efficiency of telecoms pathways by making them continuously available for multiple simultaneous connections. This is possible when data passes through such a system as packets rather than complete messages.
A data transfer scheme in which information is broken into individual packets, transferred across a communications link, and reassembled at the receiving end. In a packet-switching system, the route between the sender and receiver is determined by each node through which the packet travels.
The process of routing and transferring data by means of addressed packets so that a channel is occupied only during transmission of a packet. On completion of the transmission, the channel is made available for transfer of other packets.
1. A communications network technique that divides the data traffic into small packets, each of which has a maximum length. This technique allows for extremely efficient sharing of communication resources. 2. A technique, usually digital, in which input information—voice or data—is broken into short “packets” allowing high capacity, high speed transmission. [Source: TeleMedia].
The method used to exchange files and requests around on the Internet. In packet switching, all the file data coming out of a computer is broken up into pieces called packets, each has the address of where it came from and where it is going. These data packets enable chunks of data from many different sources to use the same lines. This way many people can use the same lines at the same time. The data packets are sorted and directed to different routes by special machines along the way until they finally reach their destination and are reassembled in the original form that was sent.
A network technique in which data packets contain addressing and error-correcting information, in addition to informational data.
networking technology used in wide area networks (WANs) that breaks up a message into smaller packets for transmission and switches them to their required destination. Unlike circuit switching, which requires a constant point-to-point circuit to be established, each packet in a packet switched network contains a destination address. Thus all packets in a single message do not have to travel the same path. They can be dynamically routed over the network as circuits become available or unavailable. The destination computer reassembles the packets back into their proper sequence.
Type of data transfer that occupies a communication link only during the time of actual data transmission. Messages are split into packets and reassembled at the receiving end of the communication link.
To break down a transmission over a network like the Internet into smaller parts called packets and split them up as they travel to their destination, with each taking the fastest possible route.
In a packet switched network, no bandwidth is ever reserved at any of the internal nodes for a 'conversation'. This means the nodes must have some kind of storage facility to cope with the fact that data may be coming into the node at a faster rate than it can get rid of it. The Internet is a packet-switched network. c.f. circuit-switching Close this window
The method used to move data across a network via protocols like TCP/IP. Data going onto the network is divided into packets-- or pieces-- each piece has to find its way to the destination using the shortest path possible. If some of the packets are lost enough of them will survive so that the data still reaches the recipient. This data can also be mingled with other data, so that the potential bandwidth available can be best used.
Communications system that uses digital packets to transmit all forms of communication signals. A single packet may represent a small fraction of a second of a phone conversation or a small piece of a much larger file or image. Each packet contains the instructions, such as destination address and order in a message, that coordinate its arrival with other associated packets. Packets are reassembled into the proper sequence at the destination. Packet switching is the primary method of communications for the Internet and other digital communications.
On a packet-switched network, the data forming a whole transmission - for example, a voice call - is broken up into a series of packets. Each individual packet is routed and carried separately across the network, using whatever capacity is available at the time. The packets are re-sequenced and re-assembled when they reach their destination.
Process whereby messages are broken into finite-size packets that always are accepted by the network. The message packets are forwarded to the other party over a multitude of different circuit paths. At the other end of the circuit, the packets are reassembled into the message, which is then passed onto the receiving terminal.
Network technology in which data is transmitted in packets. The traditional alternative was to establish a connection between source and destination and to transmit data as a sequence of bits. Packets travel from source to destination along whatever route is immediately available, and different packets in the same message might take different paths.
the method used to move data around on the Internet enabling multiple use of the same transmission line at the same time
When information is in digital form, it may be broken up into small portions, called ?packets?. These packets may then be individually encoded so that they travel independently along a computer network or other communications channel. Transmitting information along a packet-switched network does not require that a single circuit be maintained throughout transmission.
This is a network technology that breaks messages into small "chunks" (called packets) and allows those chunks to follow different routes from the source and be reassembled at the destination.
Sending data in packets through a network to some remote location. The data to be sent is subdivided into individual packets of data, each having a unique identification and carrying its destination address. This allows each packet to go by a different route. The packet ID lets the data be reassembled in proper sequence.
A method of transmitting data by breaking it up into discrete units for transport. Each unit has special identification that allows the units to be put back together correctly at the point of reception. Each unit can take a different path to the end destination, and multiple users can use the same channel at the same time. Sending smaller units through the network is also faster than sending one big piece of data.
A strategy that enables communication channels to be used simultaneously by more than one node. Before messages are transferred, they are divided into small chunks called packets, that fit easily into memory (unlike message switching, in which entire messages are moved, thus requiring storage for large messages). At the destination, the packets are reassembled into the original message.
A switching method whereby data is transmitted between terminals or computers in preaddressed "packets" of predetermined size. Since links are only busy during "packet" transmission, they are freed up to carry other packets attached to the same or other messages.
The method used to move data and voice around a network. In packet switching, all the data is broken up into chunks - each chunk has the address of where it come from and where it is going

A method of transmitting messages through a communication network, in which long messages are subdivided into short packets. The packets are then transmitted as in message switching.
A technique for handling high-volume traffic in a network by breaking apart messages into data packets that are transmitted to their destination through the most expedient route.
Describes a data signal that has been chopped into discrete pieces or packets. Like parcels, these packets can be sent individually to their various destinations by the switching fabric. The advantage is that one message or series of messages do not take over a communication channel which allows much greater bandwidth efficiency. See circuit switching.

The method used to move data around on the Internet. (Think of a train going from station to station, dropping off and picking up things along the way.)
Technique where bit grouped packets are specifically routed to their destinations based on the availability of transmission paths.
A technique of switching digital signals whereby the signal stream is broken into small packets and reassembled in correct sequence at its destination; allows high-capacity and high-speed transmission for data networks, satellite communications and secure voice communications. Private Branch Exchange: PBX; a private telephone exchange that serves a particular organization and has connections to the public telephone network; refers to a multi-line telephone exchange terminal with various features for voice and data communications.
A communications technique where data is divided into packets for transmission over a network. Each packet can travel to the destination independently, using different physical parts of the network. The packets are re-assembled when they reach the final destination.
A networking technology in which messages are devided into packets before they are sent. Each packet is transmitted individually and can even follow different routes to its destination. Once all the packets forming a message arrive at the destination, they are recompiled into the original message. Packet switching is more efficient and robust for data that can withstand some delays in transmission, such as e-mail messages and Web pages
The method used to transmit data on data networks. Unlike the public switched telephone network, packet-switched networks do not reserve a circuit between end points. Instead, they break up messages or files into many small packets. Each message packet may take a different route from origin to destination, traveling along network circuits that are shared with packets from other messages.
Packet switching refers to how data packets (data traveling to or from a server) are divided into chunks, each chunk possessing the desired data, the server it came from, and the server its going to. After it gets to the intended source, the packets are put back in order.
The method by which most data is exchanged throughout the Internet. Most data is broken down in to smaller "packets" prior to transfer, and then reassembled at the destination.
A system for efficient transmission of data over networks. Data is divided up into packets that are sent separately over a network via any available route, and then reunited at their destination.
Refers to protocols in which messages are divided into packets before they are sent. Each packet is then transmitted individually and can even follow different routes to its destination. Once all the packets forming a message arrive at the destination, they are recompiled into the original message.
The system which enables data to travel expediently across a computer network by breaking messages into packets which are individually routed between hosts, with no previously established communication path. Packets are routed to their destination through the most expedient route. The packets of a single message may follow different routes. The destination computer reassembles the packets into their appropriate sequence. Packet switching is used to optimise the use of the bandwidth.
A communications method in which variable-length packets are individually routed between hosts.
A form of data communications which breaks a data stream into small sections, sends them separately by the best available channels and reassembles the original data stream at its destination.
A means of economically sending and receiving data over multiple network channels. Packet switching takes data and breaks it down into packetsâ€”small bundles of information containing the payload and routing information. The packets are then transmitted to the receiving end, where they are converted back to the original data format. One feature of packet switching is that packets can be received out of order and then be quickly arranged into the correct order. There are slow packet switching networksâ€”like the old SNA networksâ€”and fast packet networks based on Frame Relay and ATM. Although traditionally used for data, packet networksâ€”especially well-managed onesâ€”are suitable for real-time transmission of voice and video.
The process of routing and transferring data by means of addressed packets so that a channel is occupied during the transmission of the packet only, and upon completion of the transmission the channel is made available for the transfer of other traffic.
The method used to move data around on the Internet. When a message or file is sent across the Internet it is broken up into a series of packets. Each packet is addressed and sent on its merry way. These packets are guided along their path by special computers whose job it is to keep the Internet running.
Method to send data across a network. Data is broken up into packets (chunks). Each packet has the address of the sender and the address of the destination. This way, packets from many different sources can be sent on the same line at the same time.
A method of transmitting units of data (called packets) through a mesh network. There is no physical circuit established between end points; instead, each packet is individually relayed from one switching node to the next, and individual packets may take different routes through the switching node.
The method used to transfer data through the Internet. Data is disseminated into small packets and disbursed to an address, then reassembled at that address.
A method of data transmission that sends small blocks of data through a network to a remote location. Larger files are first segmented into smaller packets and given identifying information. While the packets may then be routed separately or even arrive out of order, they are reassembled correctly on the other side. This packetization of data and information is the future of telecom as far as we're concerned.
A method for transmitting data across the Internet. Packets, which contain its origin and destination addresses, can share the same lines (of transmission), and then can be sorted and routed. Packet switching gives multiple users simultaneous access to a single line.
The method used to send information over a network. Each packet has the address of the sender as well as the destination address. This allows information to intermingle with other packets of data, without being lost or misdirected, while making it's journey over the network.
A network in which messages are transmitted as packets over any available route rather than as sequential messages over switched or dedicated facilities.
is a technique whereby a network directs individual packets of information between different destinations based on the address within each packet.
This is the method used to move data on the Internet. The data you are sending or receiving is broken up into pieces, each piece carrying the IP address of where it is going and where it is coming from. Billions of these pieces are passing through the Internet at any given time and the major node servers are sorting these pieces and routing them at incredible speeds. The E-mail you are reading or the web page you are looking at has been reassembled and delivered to your monitor after traveling across town or around the world and, best of all, you don't have to give it a moments thought.
A system for efficient transmission of data over networks. Data is split up into packets which are sent to their destination over whatever route may be available at the time, only being reunited at their destination.
A communication system where the information is transmitted in packets of a set size. These packets have address headers and find their way to their destination by the most efficient route through the network. Compared to circuit switching, where a connection is occupied until the traffic exchange is completed, packet switching offers considerable efficiencies because connections can be used by a number of users simultaneously.
A technique in which data is sent from a "sending" to a "receiving" terminal or computer in packets of fixed length. Each packet is sent separately and may be interspersed with packets from another location.
A network in which limited-length packets are routed independently from source to destination. Network resources are not reserved. Compare with circuit.
Packet switching is the method used to send data around the Internet. It works by breaking data into chunks, each chunk has an address of where it came from and where it's going. These chunks are then sent by various routes across the Internet to the destination machine, which re-assembles them in order.
In computer networking and telecommunications, packet switching is a communications paradigm in which packets (messages or fragments of messages) are individually routed between nodes, with no previously established communication path. In 2.5G or 3G, a phone call is broken into packets and sent across the network where it is reassembled into an audio stream on the other side. With packet switching, a communications channel is only tied up for the time it takes to transmit a single packet, making it generally more efficient than circuit switching, which ties up an entire channel for the duration of the transmission. If a network is analogous to a freeway, with circuit switching, a lane can only be used by one car at a time, whereas packet switching allows a lane to be used by many cars at once.
A digital transmission method that divides a data stream into small 'packets' that are then individually switched. At termination the packets are reformed into the original message. This gives the network greater efficiency per channel than circuit switching and allows always on technologies such as GPRS which are billed only when data is sent.
A method of sending data over networks, packet-switching involves breaking up communications -- be they voice, video, e-mail, or Internet transmissions -- into individually addressed data packets, which are then sent across the network to their destination. Different packets comprising the same transmission, such as a large graphic file, can be sent over different routes, and then reassembled at their destination. As a result, packet-switching can more efficiently utilize network capacity than circuit-switched networks.
Packet Switching is the method that is used to transfer data on the Internet. Within a packet switching network, the data that comes from the machine is broken up into small chunks. Each of the chunks includes the addresses of both the destination and the origin. It enables chunks of data from all different sources to intermingle with one another on the same lines, furthermore it can be sorted and re-directed along alternative routes. Through this many people can access the same lines all at the same time.
A communications paradigm in which packets (messages) are individually routed between hosts, with no previously established communication path. See also: circuit switching, connection- oriented, connectionless.
Refers to sending data in packets through a network to some remote location. In a packet switched network, no circuit is left open on a dedicated basis. Packet switching is a data switching technique only.
A method of transmitting messages through a communication network, in which long messages are subdivided into short packets and routes to its final destination.
Refers to the protocols within a network that determine how messages are broken into packets (q.v.) and routed to their destinations.
The method used to move data around on the Internet. In packet switching, the message transmitted by a computer is broken up into pieces, called packets. Each piece has the address of where it came from and where it is going as well as a message ID. The entire message is recreated at the destination from all of the pieces. This enables pieces of data from many different sources to co-mingle on the same network, and be sorted and directed (routed) to different destinations by special computers (packet-switches or routers) along the way. Thus, many people and applications can use the same network at the same time.
the technology that made large-scale computer networking possible. Instead of a dedicated connection between two computers, messages are divided up into packets and transmitted over a decentralized network. Once all the packets arrive at the destination, they are recompiled into the original message.
A method of switching data in a network where individual packets of a set size and format are accepted by the network and delivered to their destinations. The sequence of the packets is maintained and the destination established by the exchange of control information (also contained in the packets) between the sending terminal and the network before the transmission starts. The network is open to all users, all the time, with packets from the various nodes being interleaved throughout the network. The packets can be sent in any order, as the control information sent at the beginning of the transmission ensures they are interpreted in the correct order at the receiving end. Because each packet carries its own control instructions, it can use any route to reach its destination.
a type of communication that splits information into "packets" of data for transmission. This is efficient, as it only uses radio spectrum when it's actually sending something, rather than keeping an open channel at all times (as is done in circuit switching). Packet switching is a core component to 3G technology.
A method of transmitting messages through a communications network in which long messages are subdivided into short packets. Each packet is passed from source to destination through intermediate nodes. At each node,the entire message is received,stored briefly,and passed on to the next node.
Data transmission where messages are divided into packets, each with a destination address. Each packet is switched independently from others in the same logical conversation.
sending packets through a network to a remote location
Packet switching is used to describe protocols that divide messages into packets before they are sent. Each packet is then transmitted individually to its destination.

Data transmission method that divides messages into standard-sized packets for greater efficiency of routing and transport through a network.
Packet Switching is essentially a method of data transmission where small blocks of data are transmitted rapidly over a channel (such as a phone line) that is dedicated to the connection only for the duration of the packet's transmission. Packet switching is one of the fundamental concepts responsible for computer networking and the Internet. It was developed in the 1960's by Paul Baran, and was designed to help the military build a communications network capable of withstanding a nuclear attack.

Once all the packets forming a message arrive at the destination, they are recompiled into the original message. The Internet is a packet switching network.
A method of moving data around the Internet that allows many people to use the same lines at the same time. In packet switching, all data being transferred from a machine is broken into packets, with each packet having the address of its origin and destination. This enables packets from different sources to be simultaneously transferred, sorted and directed on the same line. See Also: Internet, Packet
The way that data is exchanged over the Internet.
Messages are divided into packets before they are sent. Each packet has a head and tail and is transmitted individually. Packets can even follow different routes to its final destination. Once all the packets arrive, they are recompiled into the original message.
A network that is based on small bits on data that is routed to its destination by address contained in each packet.
A process where messages are broken into finite-sized packets that are always accepted by the network. The message packets are sent across different circuit paths. The packets are reassembled into the original message at the end of the circuit.
Process of transmitting digital information by means of addressed packets so that a channel is occupied only during transmission of the packet. In contrast, data sent using circuit switching net modems occupies a circuit for the entire duration of transmission, even when no data is actually travelling over lines. Using packet switching, various packets of information can travel along different routes on the network, allowing the carrier to optimise network capacity.
The technique by which a stream of data is broken into standardized packets, each of which contains an address, sequence, control, size, and error checking information, in addition to user data.

Sending data through a network in packets, to some remote location.
A data transmission method in which data is transferred by packets, or blocks of data.
Packet switching is a WAN switching method in which network devices share a single point-to-point link to transport packets from a source to a destination across a carrier network.
The method used to move information on the Internet. All the data coming out of a machine is broken up into chunks of information, each chunk has the address of where it came from and where it is going. The chunks are then re-assembled on the computer receiving the information.
A core network transmission technique that involves splitting information into "packets" of data that are then re-routed independently through the network over different routes to the final destination. This technique is attractive for mobile access because the radio spectrum is used only when data is actually being transmitted. The alternative is circuit switching. GPRS is a packet-based technology designed for digital mobile networks.
Sending data in packets through a network to some remote location. The data to be sent is assembled by the PAD (Packet Assembler/Disassembler) into individual packets of data, involving a process of segmentation or subdivision of larger sets of data as specified by the native protocol of the transmitting device. Each packet has a unique identification and each packet carries its own destination address.

A technology for breaking data into packets and then sending the packets over a network. Each packet has a header containing its source and destination, a sequence number to reassemble the information, a block of data content, and an error-checking code. The data packets may take different routes to their destination, where the original information is reassembled after the packets arrive. The international standard for packet switching networks is X.25. See also: packet
A communications paradigm in which packets (messages) areindividually routed between hosts, with no previously establishedcommunication path. See also: circuit switching, connection-oriented, connectionless. PACKET, PACKET JAM
The method used to move data around on the Internet. In packet switching, all the data coming out of a machine is broken up into chunks, with each chunk having the address of where it came from and where it is going. These chunks of data can be sorted and directed along different routes by routers. Internet routers try and send the traffic through the most direct route, but when a user requests a web page in their browser, the files that make up a single web page may be routed along diverse networks. For instance, someone in Chicago, requesting a web page from a web server in Los Angeles, may have some of the files routed back to the user through connections in different cities (perhaps San Diego or San Francisco). Packet switching also allows traffic to be routed around connection points that are experiencing technical difficulties. So, in the example above, if the San Francisco route was overloaded or off line, the data might be diverted to Salt Lake City or Denver before resuming its path back to the Chicago web browser.
A transmission technique that maximizes the us of digital transmission facilities by transmitting packets of digital data from many customers simultaneously on a single communications channel. ... more
A data communications method based on chopping large blocks of information, such as files or images, into smaller, easily manageable chunks for transmission over shared communicable channels.
The transfer of data by means of addressed packets whereby a channel is only occur for the duration of transmission of the packet. The channel is then available for the transfer of other pack.
A technique for transmitting data in which the message is subdivided into smaller units called packets.
This terms refers to the data from one computer sent to another is broken up into packets and sent along best routes. Parts of the original data is tagged with information of where it is from and where it is going so this allows all different types of pac
A method of routing messages across a network. A packet-switching network consists of a number of packet switching exchanges connected by high-speed transmission lines. When a message is sent across the network from one computer to another, a "virtual circuit" is set up between them, and the message is split into small packets of data. Each packet contains address and sequencing information, and the exchanges are responsible for routing packets across the network, choosing the best route to allow for other traffic, storing packets until a route is clear, and making sure the packets arrive in correct order at the correct address. The network can then be shared by data traffic from many different sources, reducing wasted network bandwidth and resources. See virtual circuit.
Packet switching, in computer networking and telecommunications, is the now-dominant communications paradigm in which packets (units of information carriage) are routed between nodes over data links shared with other traffic. This contrasts with the other principal paradigm, circuit switching, which sets up a dedicated connection between the two nodes for their exclusive use for the duration of the communication. Packet switching is used to optimize the use of the bandwidth available in a network, to minimize the transmission latency (i.e. the time it takes for data to pass across the network), and to increase robustness of communication.
