Hi friends in this article let us discuss about the basic information about the Central Processing unit(CPU)

CPU which is expanded as the Central Processing Unit is nothing but a microscopic circuit and this CPU serves as the main information processor in a computer.The image below shows the CPU that we use in our houses

It is usally a single microprocessor and it is made from a wafer of the semiconducting material,which is usually silicon, and it consists of millions of electrical components on its surface.

The CPU directs the logical and arithmetical functions and also plays a vital r0le in executing the computer programs and the CPU is located on a motherboard with other chips.

The Central Processing Unit is usually regarded as the "Brain of the computer" as it is microscopic circuit or chips which  serves as the main "information processor" in a computer. As every body knew currenly we use Pentium processor which was made by the Intel and very fast development is taking place in this.

Technically speaking, CPU is nothing but a number of "interconnected processing units" and each of them is responsible for any one of the aspect of the CPU’s function.

Usually any standard CPUs contain the processing units and the function performed by these processing unit includes

i)It interpret and implement software instructions

ii)Perform calculations and comparisons

iii)It makes logical decisions,i.e., based on the Boolean Algebra it determines whether the given statement is true or fals

iv)It stores the information temprorily so that it can be used by another CPU’s processing units

v)It also keep in track of the current step during the program execution

vi)It also allows the CPU to communicate with the rest of the computer

Out of several hardware components present in a PC, the smallest hardware companent which can still perform vast operation is this computer chip and a computer chip is usually made up of the semi-conductors and also the tiny wires which are laid out on top of thin wafers of silicon.

A computer chip is formed by sandwiching the layers of wire and semi-conductors  between layers of silicon. The semi-conductors are configured in such a way to represent either a 0 or a 1 during the suply of electricity to them.

Usually most kinds of hardware are said to 'hard-wired', because once they are made, the configuration of the computer chips cannot be changed
