COMPUTER:           computer is the electronic device it  consists INPUT(keyboard, mouse..etc), OUTPUT(Monitor, printer...etc) devices and CPU (central processing unit). CPU:        CPU is also called brain of the computer.it mainly consists ALU, CU,MAIN MEMORY. it perform Arithmetic,Logical And also input output operations according to instructions Hardware:            Hardware is the physical parts or components of a computer we can also touch it such as Monitor,Keyboard,Sound Card,Hard disk drive,CDROM,RAM(random access memory ),Motherboard, Memory...etc Software:             Collection of the programme(s) is called as software. It is mainly divided into SYSTEM software (All Operating systems,Windows xp , Windows 8 , Linux..etc) and Applications software(Ms wor...
