IEEE 1394 is an interface standard for a serial bus for high-speed communications and isochronous real-time data transfer. It was developed in the late 1980s and early 1990s by Apple in cooperation with a number of companies, primarily Sony and Panasonic.
Examples of computer connector sockets on various laptops Ports on the back of the Apple Mac Mini (2005). A computer port is a hardware piece on a computer where an electrical connector can be plugged to link the device to external devices, such as another computer, a peripheral device or network equipment.

All communications are between the host and one peripheral. In a FireWire network, any capable node can control the network. USB runs with a 5 V power line, while FireWire supplies 12 V and theoretically can supply up to 30 V. Standard USB hub ports can provide from the typical 500 mA/2.5 W of current, only 100 mA from non-hub ports.
Input port may refer to: Input device, a generic term for any device that provides input to a system; Parallel port, a computer hardware interface; Serial port, a computer hardware interface; Universal Serial Bus, a computer hardware interface; IEEE 1394 interface, a computer hardware interface, known commonly as Firewire
Keyboard and mouse cables and ports are almost invariably serial—such as PS/2 port, Apple Desktop Bus and USB. The cables that carry digital video are also mostly serial—such as coax cable plugged into a HD-SDI port, a webcam plugged into a USB port or FireWire port , Ethernet cable connecting an IP camera to a Power over Ethernet port, FPD ...
Some other computer architectures use different modules with a different bus width. In a single-channel configuration, only one module at a time can transfer information to the CPU. In multi-channel configurations, multiple modules can transfer information to the CPU at the same time, in parallel.
The last Apple computer to have an Apple Desktop Bus port is the Power Macintosh G3 (Blue and White) in 1999. PowerPC-based PowerBooks and iBooks still used the Apple Desktop Bus protocol in the internal interface with the built-in keyboard and touchpad. Subsequent models use a USB-based trackpad.
The Open Desktop Workstation, also referred to as ODW is a PowerPC based computer, by San Antonio-based Genesi. The ODW has an interchangeable CPU card allowing for a wide range of PowerPC microprocessors from IBM and Freescale Semiconductor. It is a standardized version of the Pegasos II. It was the first open source based PowerPC computer and ...
