Role of computer Architecture

The main role of Computer Architecture is to balance the performance, efficiency, cost and reliability of a computer system.

For Example − Instruction set architecture (ISA) acts as a bridge between computer's software and hardware. It works as a programmer's view of a machine.

Computers can only understand binary language (i.e., 0, 1) and users understand high level language (i.e., if else, while, conditions, etc). So to communicate between user and computer, Instruction set Architecture plays a major role here, translating high level language to binary language.

Structure

Let us see the example structure of Computer Architecture as given below.

Generally, computer architecture consists of the following −

• Processor

• Memory

• Peripherals

All the above parts are connected with the help of system bus, which consists of address bus, data bus and control bus.

The diagram given below depicts the computer architecture −
