What is a Computer? – Definition, History, Types and More
A computer is a computing device capable of receiving, storing and helpfully processing information.
It is program to perform arithmetic or logic operations automatically. It is use in most Latin American countries.
Although it is more common in the masculine (‘ computer ‘) in Chile and Colombia. It comes from the English computer and in turn from the Latin computare (‘to calculate’).
What are the Parts of a Computer?
The essential elements of it is:

It is based on a sequence of unit transformations (or quantum gates) and a measurement. It uses the qubit (quantum bit) as a unit of quantum information.
And also, this type of computer can perform calculations quickly compared to regular computers.
3. Personal computer

A laptop is a compact personal computer design in one piece. And also low weight that is easily transport.
It is also currently the most popular type of personal processor. Its practicality and in some models for its low cost.
For most people, what this is a multipurpose study, work and entertainment tool.
Currently, the internet is used by approximately 3.3 billion people daily, of 7.2 billion inhabitants in the world or more.
It means that 46.4% of the world population uses the internet. Either through personal computers, mobile phones (smartphones) or tablets as the primary devices.
It has fostered the high development of technology in computers and mobile devices.
And also, we are currently having at our disposal an extensive range of brands. However, with different characteristics to choose from according to specific needs.
