1. Draw a block diagram of Computer and explain its basic parts. Computer A computer is an electronic device that performs certain mathematical and logical operations as per the instruction given by the user. OR A computer is an electronic device that can accept data, store data, process data as desired, retrieve the stored data as and when required and print the result in desired format. Block Diagram of Computer The basic components are Central Processing Unit (CPU) which consists of ALU and CU. Input Device Output Device CPU (Central Processing Unit) The central processing unit is sometime referred as the brain of computer. It is main part of computer system. All the operations within the system are processed and supervised by CPU. Thus CPU performs arithmetic and logical operations, controls the memory usage and sequence of operations. To perform all these operations CPU has three subunits. They are Arithmetic and logical Un...
