A peripheral connection standard used to connect devices to your computer. Many UPSs offer USB support.
The standard rectangular plug and socket for attaching accessories to most computers.
(abbreviation "USB") A plug and play type connection for computer peripherals, ranging from printers and scanners through to mice and keyboards. It has the advantage that peripherals can be connected and disconnected while the system is operational ("hot swapping"). The latter is essential when connecting PDAs for data synchronisation or data transfer. In most cases a computer will have only one or two USB ports, so a hub may be required to add additional ports.
( USB) A bus standard that permits up to 127 peripheral devices to be connected to an external bus.
This is an interface that is designed to provide for connectivity of up to 127 external, PnP devices to a computer system. Developed by a large consortium including Compaq, IBM and Microsoft, it was designed to replace the serial interface. Acceptance of USB has been slow despite the impressive capabilities of the technology including speeds over 10 Mbs and the ability to "hot-swap" peripherals.
A hot swappable connection interface which can connect up to 127 devices to one port. The USB 1.0 standard has 12.5MB of bandwidth which is shared between all of the connections. The USB 2.0 standard will increase bandwidth up to 480MB/sec making it more competitive with FireWire.
Serial interface that allows connection of up to 127 devices at speeds of either 1.5 or 12Mbits/s. It supplies power for those devices and allows the devices to be added and removed without rebooting.
Connection that sends information from a computer to a handheld computer, printer, camera, etc. It compresses information so it sends it faster than a Serial Port. Virtual Private Network (VPN): Network that is constructed by using public wires to connect nodes. VPNs use encryption and other security mechanisms to ensure that only authorized users can access the network and that the data cannot be intercepted.
an interface for data communications between a computer and external peripheral devices
A device for connecting various peripherals to the CPU.
Used to connect devices such as scanner, speakers and digital cameras, to a computer via a high speed single wire connection.
A plug-and-play bus or interface that allows peripheral devices such as printers and scanners to be added to a computer without an adapter card. Most PC models today include USB ports. USB ports have replaced serial and parallel ports as a faster way of connecting devices to a computer. A USB operates at speeds up to 12 Mbps; USB 2.0, which was recently released, operates at speeds of up to 480 Mbps.
A plug-and-play interface between a computer and a compatible add-on device, such as an audio player, joystick, keyboard, phone, scanner, digital camera, or printer. With a USB, a new device can be added to a compatible computer without having to add an adapter card or even having to turn the computer off. To Top
The Universal Serial Bus (USB) replaces many different types of serial and parallel port connectors with one standard plug and port combination.
Serial data interface typically used for connecting peripherals such as keyboards or mice.
This is a small rectangular port that is used to connect peripherals such as scanners, printers and digital cameras. A PC will have 4 or six USB ports. USB ports replace the parallel and serial ports used in PCs for the last several years.
USB stands for Universal Serial Bus and is a new technology theoretically capable of connecting a very large number of external devices on a computer. USB is intended primarily for low bandwidth (slow) components such as mice, keyboards, modems, joysticks, etc., but not fast devices like hard drives
is a plug-and-play interface between a computer and add-on devices (such as audio players, joysticks, keyboards, telephones, scanners, printers). With USB, a new device can be added to your computer without having to add an adapter card or even having to turn the computer off.
An external bus that is beginning to replace parallel and serial ports. With a maximum transfer speed of 12 Mbps (megabits per second), USB is designed for low- to mid-speed peripheral devices.
A digital connection between two separate electronic devices which provides "plug-and-play" capability.
A serial bus with a data transfer rate of 12 megabits per second (Mbps) for connecting peripherals to a microcomputer. USB can connect up to 127 peripherals, such as external CD-ROM drives, printers, modems, mice, and keyboards, to the system through a single, general-purpose port. This is accomplished by daisy chaining peripherals together. The USB is designed to support the ability to automatically add and configure new devices and the ability to add such devices without having to shut down and restart the system.
An input/output (I/O) bus capable of data transfer at 12 megabits (1.5 megabytes) used for connecting peripherals to a microprocessor. Typically, each device connected to a computer uses its own port. USB can connect up to 127 peripherals through a single port by daisy-chaining the peripherals together. USB devices may be hot plugged, which means that power does not have to be turned off to connect or disconnect a peripheral. It is expected that USB will become a primary means of connection in IBM-compatible PCs. Most major hardware, software, and telecommunications providers support USB. Some printers do not yet support USB, however, most of these parallel interface printers will accomodate a parallel to USB conversion cable.
A serial connection technology that is almost universally available in current PCs. Version 1.x allowed for 12Mbps transfer rates, and this was boosted...
Designed to allow peripherals to be connected to a computer without the need for expansion cards, USB ports have become standard equipment in modern computers. Most portable audio devices are connected to a computer using USB. The two most common types of USB connections are standard and mini.
(USB) A serial bus with a bandwidth of 1.5 megabits per second (Mbps) for connecting peripherals to a microcomputer. USB can connect up to 127 peripherals, such as external CD-ROM drives, printers, modems, mice, and keyboards, to the system through a single, general-purpose port. This is accomplished by daisy chaining peripherals together. USB supports hot plugging and multiple data streams.
An advanced serial interface that supports large numbers of devices. USB is much faster than traditional serial interfaces.
(USB) An external peripheral interface standard for communication between a computer and external peripherals.
A method of cabling that has its own low voltage power supply and can be used to connect computers to other peripheral devices. Due to this power source, it is possible to run small drives (USB cards) which can be used as high capacity memory sticks as an alternative to floppy disks or other portable media.
A plug-n-play standard for connecting multiple (up to 127) input/output devices to a single high-bandwidth port. The design of the bus allows hot-swapping of the devices (disconnection and reconnection without powering the computer off) and automatic configuration. The USB peripheral bus standard was developed by Compaq, IBM, DEC, Intel, Microsoft, NEC, and Northern Telecom.
A serial protocol and physical link that transmits all data differentially on a single pair of wires. Abbreviated USB. USB is an increasingly popular replacement for slower serial and parallel ports, especially for connecting to general-purpose computers. In addition to higher throughput, USB also offers the ability to power downstream devices and to connect a much larger number of devices. The USB 1.0 standard specifies two kinds of cables and two variations of connectors. High-speed cables, for 12 Mbps communication, are better shielded than their less expensive 1.5 Mbps counterparts. Each cable has an "A" connector on one end and a "B" on the other. Since the two types are physically different it's impossible to install a cable incorrectly. The interconnections of USB devices in a tiered star topology.
A standard which allows quick and easy connection of external peripherals such as scanners and printers to your PC. It supports plug and play, and devices can be added or removed with your PC switched on.
(USB) A plug-and-play interface between a computer and add-on devices.
(USB) - A hardware interface for low-speed peripherals such as the keyboard, mouse, joystick, scanner, printer and telephony devices.
Bus that eliminates the need to install cards into expansion slots. Devices connect to each other outside the system unit and then a single cable attaches to the USB port. The USB port then connects to the USB, which connects to the PCI bus on the motherboard. 4.38, 4.29, 4.32 hard drives and, 7.13
An external bus that supports Plug and Play installation. Using USB, you can connect and disconnect devices without shutting down or restarting your computer. You can use a single USB port to connect up to 127 peripheral devices, including speakers, telephones, CD-ROM drives, joysticks, tape drives, keyboards, scanners, and cameras. A USB port is usually located on the back of your computer near the serial port or parallel port. See also: port; bus; Plug and Play
A new universal connector that replaces serial and parallel connections for PC peripherals with a standard plug and cable carrying both data and power. The USB significantly increases the number of peripherals that can be attached.
Universal Serial Bus (USB) is a serial bus standard to interface devices. It was originally designed for computers, but its popularity has prompted it to also become commonplace on video game consoles, PDAs, portable DVD and media players, cellphones; and even devices such as televisions, home stereo equipment (e.g., digital audio players), car stereos and portable memory devices.
