Hard Drive (HDD/SSD)/OPTICAL DRIVE/MONITOR/INPUT/OUTPUT DEVICES/TOUCH SCREENS

A hard drive is basically these stuff:HDD-A hard disk drive (HDD)[note 2] is a data storage device used for storing and retrieving digital information using rapidly rotating disks (platters) coated with magnetic material.SSD-A solid-state drive is a data storage device using integrated circuit assemblies as memory to store data persistently.OPTICAL DRIVE-In computing, an optical disc drive is a disk drive that uses laser light or electromagnetic waves within or near the visible light spectrum as part of the process of reading or writing data to or from optical discs....MONITOR-A device used for observing, checking, or keeping a continuous record of something.INPUT/OUTPUT DEVICE-For instance, a keyboard or a mouse may be an input device for a computer, while monitors and printers are considered output devices for a computer.TOUCH SCREENS-A display device which allows the user to interact with a computer by touching areas on the screen.

CPU/RAM/MOTHERBOARDS

A CPU IS-A central processing unit (CPU), also referred to as a central processor unit,[1] is the hardware within a computer that carries out the instructions of a computer program by performing the basic arithmetical, logical, and input/output operations of the system.A RAM IS-RAM (pronounced ramm) is an acronym for random access memory, a type of computer memory that can be accessed randomly; that is, any byte of memory can be accessed without touching the preceding bytes.A MOTHERBOARD IS-a printed circuit board containing the principal components of a computer or other device, with connectors for other circuit boards to be slotted into.

TIM BERNERS LEE

Sir Timothy John "Tim" Berners-Lee, OM, KBE, FRS, FREng, FRSA (born 8 June 1955), also known as "TimBL," is a British computer scientist, best known as the inventor of the World Wide Web. He made a proposal for an information management system in March 1989,[3] and he implemented the first successful communication between a Hypertext Transfer Protocol (HTTP) client and server via the Internet sometime around mid November.

ALAN TURING

Alan Mathison Turing, OBE, FRS, was a British mathematician, logician, cryptanalyst, and computer scientist.

THE 4 GENERATIONS OF A COMPUTER

 The Four Generations of computers, starting with Colossus, the world's first electronic computer (launched in 1944), and finishing with the BBC Micro (launched in 1981) and Fourth Generation Computers, looking at how technology changed throughout these years.
