SuperIO
Super I/O (sometimes Multi-IO) is a class of Input/output, I/O controller integrated circuits that began to be used on personal computer motherboards in the late 1980s, originally as Expansion card, add-in cards, later embedded on the motherboards. A super I/O chip combines interfaces for a variety of low-Bandwidth (computing), bandwidth devices. Now it is mostly merged with Embedded controller, EC. Functions The functions below are usually provided by the super I/O if they are on the motherboard: * A floppy-disk controller * An IEEE 1284-compatible parallel port (commonly used for Computer printer, printers) * One or more 16550 UART, 16C550-compatible serial port Universal asynchronous receiver/transmitter, UARTs * Keyboard controller (computing), Keyboard controller for PS/2 port, PS/2 Computer keyboard, keyboard and/or Mouse (computing), mouse Most Super I/O chips include some additional low-speed devices, such as: * Temperature, voltage, and fan speed interface * Connect ...

Motherboard Diagram
A motherboard, also called a mainboard, a system board, a logic board, and informally a mobo (see #Nomenclature, "Nomenclature" section), is the main printed circuit board (PCB) in general-purpose computers and other expandable systems. It holds and allows communication between many of the crucial electronic components of a system, such as the central processing unit (CPU) and computer memory, memory, and provides connectors for other peripherals. Unlike a backplane, a motherboard usually contains significant sub-systems, such as the CPU, the chipset's input/output and Memory controller, memory controllers, interface (computing), interface connectors, and other components integrated for general use. Nomenclature ''Oxford English Dictionary'' traces the origin of the word ''motherboard'' to 1965, its earliest-found attestation occurring in the magazine ''Electronics (magazine), Electronics''. The term alludes to its importance and size compared to the components attached to i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
