1. Your purpose

Your purpose is very important before going for any computer because if your purpose is just for typing a document in an office and you buy a computer with a Core i9 chip, it will be like wasting of money and again if the purpose is the photo and video editing or gaming and you buy a computer with 1GB RAM, sooner you must think of buying another PC because 1GB RAM can not satisfy your purpose.

2. Processor



It is known that the processor is commonly referred to as “the brain” of computers, so it is a very important component in computers.

A processor (Also known as CPU) is the logic circuitry that responds to and processes the basic instructions that drive a computer. It is a piece of hardware that enables your computer to interact with all of the applications and programs installed on your computer.

A processor is made up of hardware that works together to deliver information, allowing your computer to complete the tasks that you request when you open an application or make changes to a file.

A processor determines quickly and slowly the performance of a computer, so ensuring your computer is working quickly and properly is very important, here, the processor speed comes into play.

A processor speed

What aids a computer processor speed are two, they are: Processor cores and clock speed, their functions are different but they’re working toward the common goal. Knowing the differences between the two can help you get a better idea of what each does and what kind of processor speed you need depending on how you’re planning to use your computer. If you’re planning to use your computer for video editing rather than just for document typing and internet browsing, you will have different processor core and clock speed requirements.

Processor cores

A processor core is a small processor built into a big processor. It receives instructions from a single computing task, working with the clock speed to quickly process the information and temporarily store it in the Random Access Memory (RAM). Permanent information is saved to the hard drive when it is requested. There is always only one processor chip. That chip can have one, two, four, six, or more cores.

Types of the processor core

There are currently common five types of Processor cores, they are dual-core, core i3, i5, i7, and i9, the difference between the five and how to determine which one you should go for in buying a new computer is explained below.

Choosing between an Intel dual-core, core i3, i5, i7 and i9

A dual-core is a CPU that has two distinct processors that work simultaneously in the same integrated circuit. This type of processor can function as efficiently as a single processor

Intel’s Core i3 CPUs are the next, they are a great choice for low-cost family PCs and ultra-budget gaming desktops. However, you are advised to buy a 10th Gen i3-10100

An Intel Core i5 is a normal place to start whether you plan to buy a laptop or desktop. choosing a computer with core i5 is never a wrong choice, particularly with the 11th generation chipsets. They are strong enough for gaming, video, and image editing. And they use less power compared to Core i7 or i9.

The Core i7 is the next which is more powerful than the Core i5 series.

And Core i9 chipsets are more powerful than i7s chipset.

Clock speed

The computer’s processor clock speed determines how quickly the processor can retrieve and interpret instructions. This helps your computer get more tasks done faster.

Clock speeds are measured in gigahertz (GHz), the higher the clock speed higher the faster the processor performance.

Faster clock speeds and processors get your tasks done quicker and reduce the time you spend performing tasks on the computer.

Now that you know the differences between processor cores and clock speed you can choose which of them is suitable for your purpose when you buy a computer.

3. RAM


Random-access memory (RAM) is a form of computer memory that can be read and changed in any order, typically used to store working data, it is a computer’s short-term memory, which is used to handle all active tasks and apps. In seeking which type of computer should be bought, the size of RAM should be taken into consideration, RAM has a great effect on how many tasks can be opened on a computer at a time, and when you open more than your RAM capacity your system will start working slowly, so it affects the general speed of your computer.

Different sizes of RAM work for different types of operating systems (OS). A RAM less than 1GB can work on Windows 7 operating system, Windows 10 requires a minimum of 1GB RAM on 32-bit, and 2GB RAM on 64-bit.

So from the explanation above you can determine the size of RAM that suits your requirement.

4. Storage


Computer storage is a mechanism that enables a computer to retain data, either temporarily or permanently, here we mean storage that retains data permanently. When we are talking about permanent storage in a computer, it is about HDD (Hard-disc drive) or SSD (Solid-state drive). Computers with SSD are lighter in weight, stronger, and have a faster read and write rate compared to computers with HDD, it makes computers with SSD more expensive than computers with HHD.

Computer storage speed is measured in rpm(revolution per speed), the size of rpm has an effect on starting up the computer operating system and programs so computers with low storage take a longer time to start up the OS and programs. For better performance, get a computer with at least 5,500rpm storage.

5. Operating system


Here we are trying to explain whether to choose a MAC or a normal PC, different operating systems can be installed on them.

There are different operating systems: Microsoft Windows, Apple MAC  operating system, Linux, and Google Chrome operating system. The common operating systems are Microsoft Windows and MAC. Apple MACs are known for their good graphics but they are expensive compared to computers using windows, so all depend on your purpose, choice, and pocket.

6. Connectivity


There are many ports for connection in computer, not all computers have all the ports but if there is a special port you need, so you need to check the computer connectivity before you buy a computer

7. Brand

There are many brands of computers such as Apple, HP, Dell, Acer, Asus, Lenovo, and many others, you have to study brands of computers, their differences in price, quality, and more before you buy a computer. the only view of computer brands is explained below.


Apple is definitely one of the luxury brands when it comes to Laptops. Apple tops the segments in the market, their computer is quality, user friendly, well designed, powerful, and friendly user interface. Their laptops are extremely attractive with an Apple logo on the back which makes them one of the best things to show off. When it comes to OS, it is very secure and easy to use, unlike Windows. Simultaneously, Apple laptops are very reliable and predictable.


HP, also known as Hewlett-Packard is one of the computer brands. When it comes to desktops, they provide the most reliable machines and are widely used by gamers and professionals.

The latest HP laptops have taken some design ideas from their contemporaries and have really raised their position. The current series of notebooks are fast, powerful, and easier for users to adopt for their projects.


Lenovo is one of the most premium laptop brands and their prices are slightly higher compared to other brands. Their laptops are ideal for all kinds of tasks and can be used by anyone including professionals, businessmen, and students.


Dell is the best Windows laptop you will certainly have to go with. Their technical support is really worth praising and is appreciated by consumers.

The majority of Dell laptops are very affordable and most of their design and hardware are simple and powerful.

Apart from the brands explained above, other brands are also good to go for.

8. Cost

The last and the most important factor in buying a computer is price, everyone actually wants the best, it is possible to get it but only when there is money.

From all the explanations above, I’m sure you can select a good computer when getting to the market.
