Fixed-length self-contained block of data that includes all relevant header information to allow switching, routing and data recovery. Synonyms: Packet
A unit of data being sent over a network. A packet includes a header, addressing information, and the data itself. A packet is treated as a single unit as it is sent from device to device.
A unit of data that is transferred across the network. The format of a data packet varies depending on the type of protocol, but it usually consists of the actual information that's being transferred, plus administrative information that helps get the actual information where it needs to go.
In networking, a unit of information transmitted as a discrete entity from one node on the netwok to another. More specifically, in packet-switching networks, a packet is a transmission unit of a fixed maximum length that contains a header, a set of data, and error control information.
a block of data unemcumbered by node packet headers and may refer to a single data item or a collection of, possibly heterogeneous, data items
Information about a vehicle or group of vehicles, or other non-voice data, transmitted via communication conduits (cellular, Internet, etc.) to the fleet management system computer.
rather than your computer and modem sending data one character at a time, when using the Internet, downloading files, or sending email, it is more efficient to send information in larger blocks called data packets.
The basic unit of information exchange between computers engaged in data communications.
Although your computer and modem can send data one character at a time, when you're surfing the Internet, downloading files, or sending email, it's more efficient to send information in larger blocks called data packets. Modems generally send packets of around 64 characters along with some extras for error checking. When downloading files using a protocol like Xmodem, however, the packets are larger. And when using Internet protocols such as TCP/IP, the packets are larger still--around 1,500 characters.
A means of transmitting serial data in an efficient package that includes an error-checking sequence.
In X.25, a block of data that transports full-duplex information via an X.25 switched virtual circuit (SVC) or permanent virtual circuit (PVC). X.25 data packets may contain up to 1,024 bytes of user ... more
A unit of information transmitted as a whole from one device to another on a network.
