What is a computer?: Computers are computing devices that can receive, store, and process information. A computer is programmed to perform arithmetic or logic operations automatically.
Parts of a computer: The basic components of a computer are memory (RAM and ROM), motherboard, CPU (acronym for "central processing unit") and input and output devices. These peripherals or peripherals are varied. Some of them are: hard disk, screen, mouse, keyboard, printer or speakers.
Computer history: Computers's originate from devices that allow mechanical calculations such as the abacus. In 1882, Charles Babbage invented the so-called differential machine. He then designed the analytical machine whose components such as memory, input current, and processor affected more computers later. The MARK-I, based on electromagnetic devices, was also a milestone in this area.
During the second half of the twentieth century, great progress was made in the development of computers. They reach a mass audience and with the ability to perform multiple functions.
Desktop: The desktop computer is a type of personal computer that, due to its dimensions and features, is used in a fixed location, usually on a desktop (for home or work use). This term comes from the English Desktop. This is how it differs from the term "laptop".
Types of computers
Quantum computer: The quantum computer is a system of quantum circuits capable of complex calculations. It is based on a sequence of transformation units (or quantum gates) and a measurement. Uses qubit (quantum bit) as a unit of quantum information. This type of computer can perform calculations very quickly compared to ordinary computers.
Personal computer: A personal computer is a microcomputer that can be used by one user at a time (or more, depending on the operating system). This concept comes from the English personal computer (PC). It is often referred to as a "personal computer" or PC to refer to commercially available computers running an operating system.
