Why are expansion buses important for computers?
Expansion bus determines what exactly can be added to system – how many add-on cards, how much memory on expansion cards, what other system components and how easy it will be to setup system. It provide a common pathway for data, address and control signals that links various components of PC.
What is the expansion bus of a computer?
An input/output pathway from the CPU to peripheral devices. An expansion bus typically comprises a series of slots on the motherboard into which cards are inserted. PCI and PCI Express are common expansion buses in computers. See PCI, PCI Express, expansion card and PC data buses. See also bus extender.
What are computer buses used for?
In computer architecture, a bus (related to the Latin “omnibus”, meaning “for all”) is a communication system that transfers data between components inside a computer, or between computers. This expression covers all related hardware components (wire, optical fiber, etc.)
What are expansion cards used for in a computer?
The primary purpose of an expansion card is to provide or expand on features not offered by the motherboard. For example, the original IBM PC did not have on-board graphics or hard drive capability.
What is the purpose of expansion bus?
An expansion bus provides an input/output pathway for transferring information between internal hardware, such as RAM or the CPU, and expansion devices such as a graphics card or sound card.
Which is the best function of the expansion bus?
Expansion buses are used to connect devices to the motherboard using the motherboard’s data bus. They allow the flow of data between that device and other devices in and connected to the computer. Early computers moved data between devices and the processor at about the same rate as the processor.
