COMPUTER CLASSIFICATION

Modern computers are electronic and digital. The actual machinery wires, transistors, and circuits are called hardware; the instructions and data are called software.

Hardware

The term hardware refers to all tangible parts of a computer system, its components are: electrical, electronic, electromechanical and mechanics. These cables, cabinets or boxes, peripherals of all kinds and any other physical element involved; contrary, support software is intangible and is called software.

One way to classify the hardware is in two categories: first, the "core", which covers all the essential components necessary to provide the minimum functionality to a computer, and on the other hand, the hardware "complementary" which, as its name suggests, is used to perform specific functions not strictly necessary for the operation of the computer.

These are some of the elements that integrate the hardware:

- Screen: comprises the display device, circuitry and an enclosure.

- Keyboard: is a means of interacting with your computer. You really only need to use the keyboard when you're typing text.

- Mouse: Your mouse probably has at least two buttons on it. The button on the left is called the primary mouse button; the button on the right is called the secondary mouse button or just the right mouse button.

- Image scanner: is a device that optically scans images, printed text, handwriting, or an object, and converts it to a digital image.

- Printer: is a peripheral which produces a representation of an electronic document on physical media such as paper or transparency film.

- Camera: is a video camera that feeds its image in real time to a computer or computer network.

- Joystick: is an input device consisting of a stick that pivots on a base and reports its angle or direction to the device it is controlling.
