Computer Hardware containing different parts which are visible to us like keyboards, printer and cables etc. The different generation are take place as going from First generation to Fourth generation, therefore hardware technology is increase. Therefore, Computer Hardware related professions define various fields electronic, telecommunication and optical engineering etc..The First generation developed the different Programmable Devices and Calculators. The Second generation containing Vacuum Tubes. The Third Generation consists of discrete transistors, SSI, MSI and LSI which further defined the Mainframes and Minicomputers. Now, the Fourth generation consists VLSI integrated circuits which also defined Mainframes and Minicomputers but in some advance area of Microcomputer bit like 4-bit ,8-bit,16-bit,32-bit, 64-bit.
Basically, Physical components of the computer called Hardware such as Input ,Output and computer buses. An input part consists of pointing device called Mouse, optical mouse, trackball etc and keyboard which consists of buttons and keys, joystick for controlling video games and the last is image scanner which scans the text or picture and convert it into digital image. An output part consists of monitor and printer. Therefore monitor is kind of display system which contain screen size, cathode ray tube whereas printer defines the hard copy of document. New generation printer technology defines Toner-based printers, Liquid ink jet printers, Solid ink printers, dye-sublimation printer and Ink less printers.

Hardware containing computer buses of short range and long range. It defines the SCSI,UBS,ATM and FDDI. Personal computer hardware consists of motherboard, Power supply, Video display controller, Removable media devices, Internal storage, Sound card or video card and other Input / output(peripherals) device also all other external devices that plug into your PC.
Computer hardware Components connect to microprocessors, specifically, the computer's central processing unit (CPU), the electronic circuit that control the process of computer. The input and output hardware interaction is controlled by software called Basic Input Output System software (BIOS).
