basic architecture of computer system with block diagram
Architecture of Computer System Computer is an electronic machine that makes performing any task very easy. In computer, the CPU executes each instruction provided to it, in a series of steps, this series of steps is called Machine Cycle , and is repeated for each instruction. One machine cycle involves fetching of instruction , decoding the instruction , transferring the data , executing the instruction . Computer system has five basic units that help the computer to perform operations, which are given below: Architecture of Computer System Input Unit Input unit connects the external environment with internal computer system. It provides data and instructions to the computer system. Commonly used input devices are keyboard , mouse , magnetic tape etc. Input unit perform following tasks: Accept the data and instructions from the outside environment.
