What Does computer Mean

The computer , that indispensable piece of equipment in today’s daily life that is also known by the name of computer or computer , is an electronic machine that allows data to be processed and accumulated . The term comes from the Latin computare (“to calculate”).

If we look for the exact definition of the term computer we will find that it is an electronic machine capable of receiving, processing and returning results around certain data and that to carry out this task it has an input and an output means. On the other hand, that a computer system is made up of two subsystems that are called software and hardware , the first consists of the logical part of the computer (programs, applications, etc.) the second in the physical part (elements that make it up like mother, fan, RAM memory).

How a computer works
For its operation, the computer requires computer programs (software) that provide specific data, necessary for information processing. Once the desired information is obtained, it can be used internally or transferred to another computer or electronic component.
Broadly speaking, a computer is made up of the monitor, the keyboard, the mouse, the tower (where the hard disk and the other hardware components are located) and the printer, and each one fulfills a particular function. On the other hand, this device is prepared to perform two main functions: respond to a particular system of commands quickly and execute programs, which consist of a series of instructions recorded in advance.

Software and hardware
The software of a computer is one of the fundamental elements for its operation, its operating system, which consists of a large platform where programs, applications or tools that serve to perform different tasks can be executed.
The hardware, for its part, is made up of memory (allows data and programs to be stored), input devices (to enter data into the computer, eg: mouse and keyboard), output devices (to view data, eg: screen or printer) and CPU (brain of the computer where the instructions are executed. The acronym is the English form of Central Processing Unit.
The architecture of computers
The first computers appeared in the middle of the last century, since then they have not stopped being manufactured, growing by leaps and bounds. Despite this, most computers today still respect the Eckert-Mauchly architecture , published by John von Neumann and created by John Presper Eckert and John William Mauchly .

This architecture conceives four main sections in a computer: the Arithmetic Logic Unit (ALU ), the control unit, the memory (a succession of storage cells that have numbers, where each cell represents a known unit of information as bit) and the input and output devices . All these parts are interconnected by a group of cables called buses.
Computers are very useful at work and study.
The importance of circuits
The connections within a computer are called electronic circuits; the most complex are those included in modern microprocessor chips, which have a very powerful ALU inside. Each microprocessor can have multiple cores and these in turn with multiple execution units (each of them has different ALUs).
It should be noted that the circuits together with those components linked to them allow executing a variety of sequences or instruction routines ordered by the user. These sequences are systematized based on a wide plurality of practical and specific applications, in a process known as programming .
De acuerdo a la manera en la que la computadora trabaja los datos que recibe puede llamarse: digital, analógica o híbrida. Las digitales procesan los datos trabajando en base a letras y símbolos especiales, las analógicas lo hacen utilizando una escala común y las híbridas utilizan ambas formas.
Tipos de computadoras
Existen varios tipos de computadoras: Microcomputadoras (dispositivos pequeños que pueden recibir una programación, en esta clasificación entran las PC o computadoras de escritorio), minicomputadoras (de tamaño medio y un poco más costosas que la PC), maxicomputadoras (sirven para controlar muchos dispositivos simultaneamente, en esta clasificación entran las llamadas mainframe) y supercomputadoras (son las más rápidas y costosas, las utilizadas para la realización de proyectos a grande escala como películas o videojuegos de última generación)
Para finalizar, algunos ejemplos de frases con este concepto: “Mi padre me regaló una computadora cuando cumplí quince años”, “No sé qué hacer: se me rompió la computadora”, “Tengo cuatro juegos nuevos en la computadora”.
