Five Essential Components of a Desktop Computer

Five Essential Components of a Desktop Computer

A desktop computer comprises of five essential parts, namely; the CPU, mouse, monitor, keyboard, and power cable. All these components are crucial for the smooth functioning of the computer. Below, we take a look at the features of each element.

CPU

Also known as the computer case, this is an integral part of the computer. Inside the CPU, you will find several components, including the motherboards, processor, GPU, RAM, drive, and coolers, just to mention a few. These computer cases take different forms; from the tower designs to the small form factory models.

Monitor

The monitor displays text, video, and graphical information processed in the CPU. There are three types of monitors, namely  Liquid Crystal Display monitors (LCD ), Cathode Ray Tube monitors (CRT), and Light-Emitting Diodes monitors (LED). CRT monitors are the oldest; heavier and bulky. LCDs are thin, hence the flat screen feature. LED screens are available in either flat or curved shape and have high contrast and clarity.

Keyboard

The keyboard is an input device which enters data into a computer through typing. There are various types of keyboards to choose from. They include wired keyboards, wireless keyboards, ergonomic keyboards, multimedia keyboards, virtual keyboards and mechanical keyboards among others. Most are similar, except for a few with different key locations.

Mouse

The mouse is the device which points, selects, clicks or even moves an item on the screen through a cursor. They can either be wired or wireless. There are two types of mouse; mechanical and optical. A mechanical mouse uses a rolling ball to detect the cursor, whereas an optical one detects the cursor by use of an electric eye. These two mouse types serve the same purpose, you just chose the one that suits you.

Power Cable

The power cord connects the CPU and monitors to the mains. Some models may have surge protectors, while others don’t have this addition. You can also choose to use a UPS just in case there is a blackout.

Summary

These are not the only desktop components, but they are the essential ones. You might also need to invest in accessories such as webcams, headphones, TV cards, and so on. It just depends on the type of tasks you handle.
