Function Computer Components

The computer is an inevitable device of our everyday life. Most of us how to complete our work or meet our needs using a computer, but do not know how our computer work. But to complete our work smoothly using this device and to increase the lifespan of our device, it is important to know how this device works.
But before understanding the working process of computer you must have to be familiar with the components of your computer.

Components of Computer

  1. Computer Case
  2. Motherboard
  3. Power Supply Unit (PSU)
  4. Central Processing Unit (CPU)
  5. Random Access Memory (RAM)
  6. Drives
  7. Cooling device
  8. Power Cables

Now we are going to discuss about the basic function of these components:

Basic Function Computer Components

Case

For desktop PCs, the case is a type of box with vents, lights and places for attaching cables and USB devices. Cases are of different sizes and designs. But if you think that computers of larger case are more powerful than the computers of small cases, then you are wrong. Case size does not indicate the power of a computer. Actually, computer manufacturers design or select computer cases on the basis of the motherboard so that the motherboard can fit inside the case properly.
For laptop, case includes keyboard and screen.

Motherboard

The motherboard is the primary circuit board of your PC. All components in the interior and exterior part of your PC (Central Processor and the Memory cards as well as graphics cards, sound cards, video cards, any ports such as Firewire USB 2.0 or and the DVI port which handles the Monitor), is connected with the motherboard in some way.
Motherboards come in different sizes and standards. Actually, motherboards vary by the type of removable components which are designed to handle internally and also the ports that are available for attaching external devices.

Power Supply Unit (PSU)

The Power Supply unit (PSU) is a switch operated unit. It converts mains AC electricity into DC electricity and supply powers all the internal components, except complementary metal oxide semiconductor (because it is powered by a complementary metal oxide semiconductor on the motherboard). PSU has many cooling systems to control the temperature. For example, a fan is placed on the front to make sure that power constantly flows to the PSU and keeps the system cool, so it does not break down.

Random Access Memory (RAM)

RAM is one kind of temporary computer data storage, which deals with temporary data requests, such as keeping windows open on a desktop or just viewing a file. For a speedy PC, a fast CPU and an ample amount of RAM are necessary. Each PC contains the maximum amount of RAM that it can handle (8GB RAM is the biggest and 1 GB is the smallest). Slots on the motherboard indicate the type of RAM the PC requires.

Drives

A drive is a data storage device. Based on the type of drive controller technology (such as the older IDE standard and the newer SATA standard), a drive is connected to the motherboard of the computer. A hard drive or solid state drive stores a PC’s operating system and software. Hard drives retain data even if the machine is powered off or cut off unexpectedly because of a power cut. Thus Data can be lost if the hard drive breaks or becomes corrupt

Cooling devices

Overheating creates a bad impact on your PC’s components and circuitry. Although the CPU and other components can handle a certain amount of heat, but excess heat is very harmful for your PC’s components. So, it is very important to control the temperature of your PC.
To control your PC’s temperature, you can use fan- the most common cooler device. You can also use water-cooled system to prevent over-heating. But this is an expensive heat management system.

Cables

Without power cables, computer cannot work. All the components mentioned above so far are connected by some combination of power cables. Cables are designed to carry data or power or both. PCs are constructed so that the cables can fold properly within the case and do not block air flow throughout it.

Conclusion:

In this article, we only tried to introduce you to the core components of a PC and their functions. But a PC is typically much more than these core components. It has many internal and external parts which have different types of function.
