The hardware components of a personal computer include Motherboard, Standard Input Output Technique (BIOS), Central Processing Unit (CPU), Memory (RAM), Disk Drives, Sound Processor, Video Processor, Floppy Disks, Challenging Drives, CD-ROMs, DVD-ROMs and Adapter Cards.
Pc Computer software
Application is a set of directions telling the computer how to procedure, store and retrieve data. Software program is basically of two kinds: Operating Systems and Applications.
An Operating Program is a kind of computer software used to run the computer. It gives us with an interface with which we can issue commands to the computer technique.
