What to look for when choosing a computer

What to look for when buying computers. There are so many computer brands today, and various operating systems. You can choose windows, google and Apple operating systems and there are also other choices. Most people choose the system they want by where it will be used. If at home or the office then a desktop is the answer. Maybe you want to use it where ever you are then you need a laptop. If portability is not an issue then choose a desktop.

By getting a desktop, it’s very likely that you’ll get more performance for the same money. Also more flexibility in customizing the machine once you buy it.

Computer catagories

Those are two major categories of computer, but there are variations to consider. Choices among computers are becoming more confusing as the differences between type of computer change. Some new desktops are almost as small as a laptop. Also you can easily find a laptop that’s just as powerful as a desktop. There are also new categories, such as laptops that can be used liked tablets and all-in-one desktops that don’t need a separate monitor.

Desktop Computers

Many people have moved away from desktops. Desktops typically offer more performance for the money and are less expensive to repair. They generally come with better speakers, and allow you to view your work on a larger screen.

Laptops let you use your computer away from your desk, but you pay for , a higher price, and often reduced performance. A laptop can also be more difficult and expensive to repair than a desktop.

Choosing a Processor, an OS, and More

Speed matters. Processors with multiple cores can process more data simultaneously, with four cores now increasingly common on laptops.

Clock speed, measured in gigahertz (GHz), helps determine how quickly a processor can process information. Generally, within a processor family, the higher the clock speed, the faster the processor. Clock speeds typically start at around 1 GHz for a mobile processor. Speeds can exceed 5 GHz for a desktop processor.

Power Consumption


Another important factor when choosing a processor, especially for laptops: Lower power consumption equals longer battery life.

If you’re looking for a very basic or budget computer to browse the web, email, and work on Office documents, basically every processor on the market should be sufficient.

How Much Memory?

Memory is measured in gigabytes (GB). On both desktops and laptops 8GB has become common, with 16GB found on higher-end devices. Unless you regularly have multiple large apps open at the same time, 8GB should be your target.

Operating System

This is largely a personal choice both windows and mac are easy to use operating systems and people get used to them. Most people tend to stick to what they know.

What Graphics Adapter and Graphics Memory


Also known as the video card, graphics processing unit (GPU), or graphics card, this is responsible for what you see on your screen. Graphics processing comes in two types: It can either be integrated into the same chip or it can run on a discrete piece of equipment. If it is integrated then it cant be upgraded easily
