1. Study Centre Satya Priya Roy CollegeOf Education. 2. Central processing unit is themost important device locatedat the core of the computersystem. It is an integratedchip housed in a plastic case.It has metal legs that fasten itto a circuit board made offiber glass. They also carryelectrical impulses into andout of CPU. It is made up of asingle integrated circuit whichis called microprocessor. 3. Central Processing Unit is oneof the main components of thecomputer system. It executes theinstructions of the program tocomplete a task. It process thedata received by it and producesthe useful information. All thetasks required to get the resultare processed through centralprocessing unit. Hence it isknown as the brain of thecomputer system can just like ahuman body does not functionswithout the brain, a computercannot function without a CPU. 4. The major responsibility ofthe instructions is with theCPU. The instructionsexecutions takes place in theCPU registers. The CPU in amicrocomputer is amicroprocessor chip. 5. The CPU itself has threeparts, namely, memory unit,control unit (CU) andarithmetic logic unit (ALU).The processing speed, thesize of internal memory andthe capability of ALU etc, alldepend upon the type ofmicroprocessor chip chosen. 6. It is one of the parts of centralprocessing unit. This controlsall the parts of computer. Itdeals with the input as perthe instructions using thememory, and the ALU. Afterthe processing, it sendsresults back to the memoryfrom where they reach theoutput device. It helps to takestored instructions insequence one at time. Itinterprets each instructionsand prompts its executions byone of the units like input,output, storage or ALU. 7. It is one of the parts of centralprocessing unit.
