Importance of bus in computer system

Answer:
importance of bus in computer system
Explanation:
A bus is a set of wires that is used to connect the different internal components of the computer system for the purpose of transferring data as well addresses amongst them. Bus width will equal the word length (in bits) of the memory. There may be many buses in a computer system. A bus can either be a serial bus or a parallel bus. In serial bus, only one bit of data is transferred at a time amongst the various hardware components. In contrast, in parallel bus, several bits of data can be transferred at a time amongst the various hardware components. The speed of bus is measured in terms of the number of bits transferred per second between two components.
Fig. 1.8 shows a bus system used in a computer system. In this figure, there are two types of buses – data bus and address bus. Apart from data and address buses, a third type of bus, which is known as control bus, also exists in the computer system. The control bus manages the transfer of data and addresses among various components by transferring appropriate control signals.
