The internal bus allows the processor to communicate with the system's central memory (the RAM). 0000004767 00000 n The Universal Serial Each wire in the bus carries a bit(s) of information, which means the more wires a bus has, the more information it can address. 0000005343 00000 n Both serial and parallel buses are detailed. Print Book & E-Book. In computer architecture, a bus (a contraction of the Latin omnibus [citation needed], and historically also called data highway) 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.) In order for these components to communicate with each other, they make use of wires that are known as a ‘bus’. The control bus, like the other buses, is simply a set of connections among the parts in the computer. A bus is a common pathway through which information flows from one computer component to another. Answers - Data bus. They will make you ♥ Physics. - Address bus. 0000005926 00000 n - Control bus.
