Arithmetic Logic Unit(ALU):
Arithmetic logic unit of a computer system is the place, where the actual executions of instruction, takes place during processing operation.
Storage Unit:
Primary Memory: It is volatile ( loses data on power dissipation). It is used to hold running program instruction, data, intermediate results, and results of ongoing processing of jobs.
Secondary Memory:It is non-volatile (retains data even without power).It is used to hold stored program instructions and a large volume of information.
Output Unit:
· It accepts the results produced by the CPU.
· It converts these coded results to human acceptable form.
