The Main Hardware of Computer - written by andreas lee

Have you ever know what is contained by your computer? Computer is a complex machine that contains variety hardware and each of them has different function. As a computer user, you need to know about the hardware which work together make computer become a complex machine.

Currently, 6 types of hardware are consisted in a computer system but some advanced computers have a few more hardware. This article will explain the name of every hardware and their job in a computer system. I will explain step by step from the lower level based on their function.

1. Power Supply Unit

Power supply form is like rectangular box that supplies power to the other components. Its position is generally on the corner of CPU. To locate it, take a look on the back of computer where it is linked with the power cable.

Recent power supplies come with 50 watt increments, for instance 350 watts, 400 watts, 450 watts, etc.

2. Motherboard

Motherboard is the brain of a computer, also known as mainboard and system board. All components are connected to motherboard and through it, these hardware are work together.

3. Central Processing Unit (CPU)

CPU is the very important component. Its basic function is running all of computer programs. Sequence of numbers representing the programs that kept in computer memory.

It is also controlling and operating the other units operations in the computer system. Each hardware has their own specifications and these specifications are calculated to generate computer system performance. The faster the performance, the faster the data access while using computer.

CPU performance is also measured based on processor speed in gigahertz (GHz) which has developed more than 3.8 GHz today.

4. RAM (Random Access Memory)

RAM is a data storage form. There are different types of RAM with different speeds. When pay money for a RAM memory, you should choose the compatible type with your motherboard so it can work properly. The higher RAM installed in your computer, the higher speed will be delivered by the computer.

5. Hard drive

Hard drive is a place to save entirely files in a computer includes game applications, software, operating system, etc.

Recently, hard drive capacity size is getting larger along with the size of data and more than 1 TB capacity of internal hard drive has been invented. With that large hard drive capacity, you're able to store a huge amount of data without being afraid the hard drive is full.

6. Cooling fan

The louder smooth sound heard when you use computer is coming from cooling fan. The cooling fan helps the computer system temperature keep in low level. Without it, the temperature is easily to get hot since the heat generated by the other hardware while they are running. It gets the heat out of the CPU in order to make computer works well in secured temperature.

For additional hardware, external hard drive is a stand alone hardware separate with those six components. This external device is must-have computer accessory since it can be a backup tool for your valuable files and it is easy to taken handy because of its weightlessness and portability.
