(2) The CPU incorporates several major components (as shown in Fig. describe their major functions. 1). Please Solution CPM stands for Central Processing Unit. It\'s also called as processor . It is considered a s brain of a computer. Is is responsible for performing all functions and processes. It is made up of various transistors and each transistor receive a set of inputs and produces output.The CPU mainly interacts with main memory,referring to it for both instructions and data. The main components of a CPU are listed below: a)Control Unit This is reponsible for fetching the instructions from main memory and the executon of these instructions. It uses electrical signals to instruct the whole computer system for carrying out or executing,already stored program instructions.Its name clearly shows that it controls and co-ordinates computer components.It extracts instructions from memory and decodes and executes them.In fact it regulates the flow of information through the processor. It acts as a bridge between arithmetic unit and memory. b)Registers Registers are temporary storage areas which are responsible for holding the data that is to be processed.They store the instructions and data in a processor.This data is further used by Control Unit.There are some registers that are set aside for specific tasks, these generally include a program counter, stack, and flags. c)Combinational logic This is responsible for performing all arithmetic and logical operations. It performs arithmetic calculations like as addition, subtraction, multiplication and division as well as comparisons.The unit can compare numbers, letters, or special characters.There can be more than one Arithmetic logic unit in a CPU, and these ALUs can also be used for the purpose of maintaining timers that help run the computer. d)Main Memory e)Input/Output:Input sends data to a CPU and output makes the processed information available for the other devices to consume. .
