What is a Computer?

Many of us have experience using the technology, but do we know its very definition? When people are asked to define it, they mostly say that it is an electronic device used for internet surfing, typing, editing, or gaming. Although it’s right, let us dig deeper into the standard definition of a computer.

As said, a computer is one electronic device that can hold and manipulate information. A programmable device performs several functions, including information storage, retrieval, processing, and calculations. Also, it can be used in writing, editing, creating, and playing with the help of the installed software.

Parts of a Computer

To help you learn about computers, below are the parts of the computer and their functions.


It is the main system attached to a computer case. It is considered the blueprint of the computer as a component that makes the computer perform its central ability is found here. Without it, the computer won’t work. One of the best motherboards this year is the Auros Pro. It’s fast and equipped with all the latest technology.


It is a part located in the Motherboard. Its job is to process all the information computers need. It serves as the brain of the device. One of the emerging CPUs is the i9 extreme. It has a frequency of 4.60 GHz and a processor of 3.00 GHz. Also, it has a maximum memory of 256 Gb.


Now, for the computer to enable its ability to write and read along with data storage, this part is responsible—for storing all information before the CPU processes it. Now, if your RAM is slow, it will affect your computer’s overall performance. To recommend Corsair Led; it is one of the fastest RAMs.

Graphics and Sound Card

As the name implies, the former is responsible for sending information and data reflected on the screen as processed by the CPU, which was sent by the motherboard. On the other hand, the latter shares similar functions, except it focuses on sound. If you are curious about which brand is best, then the Asus Graphics card can be your go-to, and Blaster Z for a booming sound tech. The two are known for their great performance yet friendly price.

Power Supply Unit

When power is cut off suddenly, chances are it will create damage to your computer. This is where the power supply comes in. It converts AC to Dc so computer parts can receive the necessary current. It will also aid the computer to adjust slowly when electricity is suddenly cut off. Corsair PSU can be the option for affordable yet complete set protection.


Of course, without it, all will be nothing. A monitor is responsible for displaying all information processed by the CPU. It helps to visualize the information released by the board. Each monitor may vary in size. You can try on Samsung and scroll all the different monitors they have that are made with the latest technology and designs.


A device connected to the motherboard enables the user to communicate through typing. Once the key on it is stroked, Ram records it, the CPU process the information, and the motherboard sends it to the monitor for display. Logitech MX is one of the leading brands in this industry. They have different designs on their board, including their size. Also, it is equipped with a Bluetooth connection.


Another input device controls the computer cursor for pointing and clicking on a computer monitor. It enables interaction between the user and the software displayed on the screen. Razer is one of the most well-known mouse manufacturers out there. It is unique, equipped with the latest sensor, designed ergonomically both for hands, and does personalization in designs.

Webcam, Microphone, and speaker

A computer is not complete without this three. Webcams are used to take videos and pictures, microphones for sound recording, and speakers for sound generation. Investing in quality materials for these parts will surely help whether you are working or studying. For a clear 1080 p image, try Logitech Pro, Logitech yeti for clear, audible, and strong voice broadcast, and Pebble V2 for a minimal yet modern sound system.

These 10 are the essential computer parts you should know and invest in. All play an important function, and without these parts, your computer won’t work in its optimal condition. Knowing this can help you determine what might be wrong with yours and how to choose the best parts to replace with.
