What is cpu

CPU stands for Central Processing Unit in "English", or " Central Processing Unit " in Spanish. It receives this name because, in fact, it is where all computer operations are processed. So the chip where the elements are located is called the CPU processor, popularly known as the "computer brain."

Operations are managed in different components, according to their nature. Calculations such as addition, subtraction, multiplication, and division are represented in the ALU (logical arithmetic unit), as well as Boolean operations (logic tests). The UC (Control Unit) is already responsible for dealing with the others, in addition to controlling the operation of the central process unit as a whole.

In addition to these two, the CPU still has loggers, a low memory, and super capacity. She follows the instructions, or values ​​in the registers, that will be used in the processing of each command.

The speed at which information is transmitted is called "clock". This rate is measured in Hertz (Hz) and is always expressed in the processor model. Every 1 Hz equals one instruction per second. Thus, the 2 GHz Intel i7-5550U, for example, can perform 2 trillion instructions per second.

Difference between CPU and cabinet or chassis

A very common mistake is to call the cabinet as CPU. It is true that the processor is inside the piece, but it also supports a hard disk, CD / DVD player and a host of other hardware that does not perform the data processing function.
