What is a computer?

A computer is a device/machine that receives input from a user and it will return an output, and it means that when you give a computer a command it follows your request, so it can answer you with a result. All computers make orders in a quick orderly way, and by that it uses a microprocessor, just like a car, a microwave, and even your TV.

Hard Drive (HDD)/SSD

A hard drive is what stores all the data you have in side your computer, for instance your files, music, pictures, are all located in a hard drive, a common hard drive is somewhat larger than your typical hand, yet it can hold maximum of 100 GB.

Optical Drive

optical refers to see/vision, in the "computer world" optical refers to lasers, which can read data on an optical disc, the kinds of optical discs you may recognize are CDs and DVDs, they are made up of millions even billion small bumps, and dips. As you know optical drives have lasers, these lasers read these small bumps and dips as ones and zeros, which most computers can understand.


The screen of a computer, it shows you what you are doing on the computer, it shows pictures, monitors often look like televisions, the difference between the two is that a monitor does not have a TV tuner, so it can change channels. It is like a viewer that displays what the computer sends to it.


The Central Processing Unit (CPU) interprets and executes most of the commands from the computer's hardware and software. you can consider the CPU as the "brain" of the computer.


RAM, is an acronym for random access memory, its a type of computer memory that can be accessed randomly. RAM is the most common type of memory found in computer and other devices, such as printers.

Operating System

An operating system or "OS," is a software that communicates with the hardware and allows other programs to run the computer. It is comprised of system software, or the centeral files your computer needs to boot up and function. Every desktop computer, tablet, and smartphone includes an operating system. Common operating systems: Windows ,Mac OS X, and Linux, and the first known use of operating system was in 1961.

Tim Berners-Lee

Tim Berners-Lee is a British scientist who invented the World Wide Web or WWW in 1989 (thanks to him we have the INTERNET!!!!) . He has found and Directs the World Wide consortium , He also has found the Web foundation, and co-founded the Open data institute in London. His research group at MIT's Computer Science and Lab ("CSAIL") plans to re-Decentralize the Web, which means to update it, or make it more decent for users. Tim spends a lot of time fighting for rights such as privacy, freedom and openness of the Web.

Alan turing

Alan Turing was an english mathematician, and the founder of modern computer science,

he was not well-known during his lifetime, but today he is famous for being a passionate British mathematician, who conceived modern computing.

The five generations computers, WAS four generations.

  1. First Generation (1940-1956) Vacuum Tubes
  2. Second Generation (1956-1963) Transistors
  3. Third Generation (1964-1971) Integrated Circuits
  4. Fourth Generation (1971-Present) Microprocessors
  5. Fifth Generation (Present and Beyond) Artificial Intelligence
