Hardware
The hardware components of a computer are those parts that you can see, and touch. The smallest piece of computer hardware is a chip. The computer chip consists of layers of wires and semiconductors. Semiconductors in the chip are configured to have 0 or 1 when the electricity passes. Computer hardware components include motherboards, basic input system (BIOS), central processing unit (CPU), memory (RAM), disk drives, sound processor, video processor, floppy disks, hard disks, CD-ROM and adapter cards.

Computer Software
Software is an instruction set that informs you about processing, storing, and retrieving data on your computer. The software is basically two types: operating systems and applications.

Operating Systems
