Itroduction:

What Is CPU?

The central processing unit (CPU) is the portion of a computer system that carries out the instructions of a computer program, to perform the basic arithmetical, logical, and input/output operations of the system. The CPU contains microprocessor, memory, mother board.

    Microprocessor:

 The microprocessor is an integrated circuit that contains millions of transistors interconnected by small aluminium wires. The microprocessor’s processing capabilities control and direct the activities of the PC by interacting with the other electronic components on the motherboard.

    Memory:

Memory is a capacity of computer to store data. There are two types of memory 1.RAM 2.ROM.  RAM is volatile memory it can lose data when the computer is off.  ROM is non-volatile memory it can not lose data when the computer is off.

    Motherboard:

In personal computers, a motherboard is the central printed circuit board (PCB) in many modern computers and holds many of the crucial components of the system, providing connectors for other peripherals. The motherboard is sometimes alternatively known as the main board,system board, planar board or, on Apple computers, the logic board. It is also sometimes casually shortened to mobo.

Background/History:

The First CPU was made in the 1940s and was ran with the first computer the EDVAC (Electronic Discrete Variable Automatic Computer).

The EDVAC was one of the first functional Electronic Computers

Advantages Of Computer:

It helps you automate various tasks that you can not do manually.

helps you organize your data and information in a better way.

It has much more computing and calculating power then an ordinary human.

It may help your work to be a lot easier.

It may be the storage of your important data and files.

It may help you solve problems faster than an ordinary human being can do.

It has speed, storage, reliability, consistency and communications.

It helps you to find useful information using the Internet

It helps in businesses, factories, offices, schools and homes.

Disadvantages Of Computer:

It can potentially destroy your social life and interactions with humans if you do not maintain the balance.

It may effect to the destruction of your eye sight due to radiation.

It may cause pimples and wrinkles.

It may damage your studies and life

Too much time in front of monitor may adverse effect your eye sight and can also make you fat.

The way it distracts and can deviate our thoughts and activities towards unproductive activities.

It could cause violation of privacy, impact on labor force, health risks, impact on environment, distraction from work, and possible antisocial influences.

CPU Problems                  Their Solutions

Computer is slow                                        Could be hard drive is fragmented or

Starting to fail, not enough RAM or an old                                                                           CPU.

Computer keeps restarting                      Could be graphics card, motherboard or

network card drivers.
