Computer Things.
Called the computer a machine capable of several types of automatic processing of information or data processing. Examples of computers include the abacus, a calculator, computer analog and digital computer. A computer can provide up of many attributes, among them data storage, data processing, calculation on a large scale, industrial design, graphic imaging, virtual reality, entertainment and culture.
In the past, the term has been applied to persons responsible for some calculation. In general, the term computer a physical system that performs some type of computing. There is also a rigorous mathematical concept used in the theory of computation.
It is assumed that personal computers and laptops are icons of the Information Age [1], and this is what many people consider as “computer”. However, currently the most common forms of computer in use are embedded systems, small devices used to control other devices such as robots, digital cameras and toys.
A computer always needs at least one program running all the time to operate. Typically this program is the operating system (or operating system), which determines which programs will run, when, and what resources (such as memory and I / O) it can use. The operating system also provides a layer of abstraction over the hardware, and gives access to other programs providing services such as device manager programs ( “drivers”) that allow programmers to write programs for different machines without having to know all the specifics of electronic devices each.
