Cpu Microprocessor Pentium II - IV

Cpu Microprocessor for the computer is the instrument through which data is collected and, after processing and storage, are produced meaningful information for the user.
 
To do this it needs to be a part of devices that allow the user to input data to be processed and the other will enable them to display and store the results obtained and the information sought.
These devices are referred to as input (input) and output (exit).   
The most common input devices: keyboard, mouse, scanner, microphone.
While for the output devices, they are: the monitor, speakers, printer. 

 
This component, aiming at collecting data and the issue, these units are generally peripheral, as opposed to the central unit, also called the CPU MICROPROCESSOR, which is the set of components (microprocessor and memory) assigned to perform processing.

Cpu Microprocessor for the CPU (Central Processing Unit) which performs millions of operations per second, is without doubt the most important and distinctive component of a computer.

Its task is to take care of all the operations required by applications and operating system.

Often the terms CPU and processor are used interchangeably, however, we will call more precisely cpu microprocessor, or simply processor, the integrated circuit (chip) made of silicon, which performs data processing operations, while we denote the set of CPU and microprocessor main memory.

cpu microprocessor is a chip installed on a tiny piece of silicon.

Contains millions of transistors that are interconnected by very fine traces of aluminum.

The transistors used to store and manipulate the data so that the cpu microprocessor can perform a wide variety of useful functions.

The history of the processor goes back to 1971, when a small, unknown companies put together transistors to form a central processing unit which would be called the Intel 4004.

Since then, Intel has continued to sign their processors with numbers up to what should have been called the 80586, but rather for commercial reasons (it is a registered trademark), was called Pentium.

Cpu Microprocessor then were born the Pentium II, Pentium III and Pentium IV the present.
As for the MMX (Multi Media Extensions) just remember that identify a set of processors augmented with additional instructions that make them particularly suitable to run multimedia applications.

With regard to the suffix Pro, it refers to processors with the second-level cache integrated on the chip that also contains the cpu microprocessor.

In recent years they have made their appearance just as other companies that offer good processors, and particularly advantageous quality-price ratios, they are AMD and Cyrix.

The microprocessor is composed of a control unit (CU = Control Unit) and an arithmetic-logic unit (ALU = Arithmetic Logical Unit).

The controller oversees the operation of the CPU and runs, one by one in a correct order, the instructions that it should fulfill.

It serves as a coordinating and monitoring the implementation of programs and peripherals, giving the commands that are used to getting what is required by the software.

The ALU performs the other hand, logical operations and arithmetic instructions contained in the programs, and achieve a result which is then stored in a given memory cell.

The data is transferred to and from the processor through special channels called BUS.

Of course, the greater the speed of data transfer through these channels, the better the performance of your computer.

Newer computers typically use a bus speed of 133 Mhz and beyond.
