What is computer

Stand

These are all tangible parts of a computer system, its components are: electric, electronic, electromechanical and mechanical.

Input devices

Microphone

Its function is to translate the vibrations due to acoustic pressure exerted on the capsule by the sound waves into electrical energy, which can for example record sound from any place or item.

Touch Screen

Its function is through a direct touch on the surface, allows the input of data and commands to the device, and in turn shows the results previously introduced, acting as input device and data output peripheral.

Keyboard

Its function is to use buttons or keys, to act as mechanical levers or electronic switches that send information to the computer.

CPU

HDD

Its function is to store data, as it uses a magnetic recording system to store digital data.

RAM

Its function is randomly accessed, ie can access any byte of memory without accessing the preceding bytes.

Motherboard

The motherboard is the most important component of a computer, its function is to coordinate all the other elements that allow it to function properly.

NIC

Its function is to allow communication with devices connected to each other and to share resources between two or more computers.

Soundcard

Its function is to allow the audio output controlled by a computer program called a driver.

Video card

Its function is to process data from the CPU and into information understandable and representable in an output device such as a monitor or TV.

Optical drives

Its function is the massive data storage, uses a system of reading and writing is done through a laser.

Microprocessor

Its role is to implement the programs, from the operating system to user applications; programmed instructions executed only low-level language, performing simple arithmetic and logical operations, such as addition, subtraction, multiplication, division, the binary logic and access to memory.

Output devices

Printer

Its function is to produce a continuous range of text or graphics of documents stored in electronic form on physical media by printing, normally on paper or transparencies, using ink or laser technology.

Speakers

Its function is to reproduce sound from an electronic device uses electrical waves of mechanical energy and this energy is converted into sound.

Screen

Its function is to display data or information on the CPU.

It is the software of a computer system, comprising all the necessary software components that enable specific tasks, as opposed to the physical components, which are called hardware.

It is divided into

System software

Its function is to allow administration of the physical or computer resources, is that interfaces between the user and the computer hardware components, including operating systems have.

Application software

Its function is to execute specific tasks such as editing text, images, calculations, etc., among them are office suite and graphic design packages.
