What is a processor?

The processor, or CPU, is the brains of the operation. It controls how your computer performs and the type of processor determines everything from speed to multi-tasking and how it handles intensive tasks. The key features of a processor to look out for are cores and clock speed.

How do processor cores work?

All processors are made up of a number of cores - dual core means two, quad core means four and octa core means eight. When a computer is running, it assigns a core to each task that is being performed. This means that a quad core processor will cope better with multi-tasking than a dual-core processor, as it has more cores to use for each task.

What is clock speed?

Clock speed is measured in GHz (gigahertz) and defines how fast a processor is. Better processors will feature a turbo mode, which allows them to increase the clock speed when faced with more demanding tasks, giving you an extra performance boost when you need it most.

What types of processor are there?

Intel and AMD are the main developers of computer processors. Intel’s range includes basic Celeron and Pentium processors and the higher performance i3, i5 and i7 range. The most common AMD processors are the basic E range, the faster A series range, and the high performance Ryzen processors. The general rule of thumb is that the higher the number in the range, the more powerful the processor.

What is an operating system?

An Operating System (OS) defines the way a computer is designed to run and function. The main operating systems are Windows, macOS and Chrome. Windows is the most widely used OS, while macOS is only found in Apple products. Chrome OS is used in Chromebooks.

What is a graphics card?

A graphics card produces the image that you see on a laptop screen or desktop monitor. For gamers, the graphics card is one of the most important things to consider. AMD and Nvidia are the main producers of graphics cards and the better the card, the better visuals you get when playing games. It usually isn’t possible to upgrade your laptops graphics card like you can with a desktop, so it’s important to choose the one you need first time.

What is RAM?

RAM stands for random access memory. The more RAM you have, the faster and easier it is to access your files. It’s essentially your computer’s short term memory – the more RAM it has, the more it can remember at one time. 2GB is recommended for basic use, 4GB should be fine for most everyday users, while 6GB and 8GB are perfect for gaming and more demanding tasks.

What’s the difference between SSD and HDD storage?

HDD and SSD are the two types of permanent storage that come with a laptop or desktop. SSD stands for Solid State Drive and HDD stands for Hard Disk Drive. The benefit of SSD is that it uses less power and lets you access your saved files much faster. However, HDD is still a great option as it's generally cheaper per byte and the most commonly used type of storage.

Choosing the best printer for your home

Inkjet and laser printers are the two main printing technologies on the market. Inkjet printers have an internal print head containing thousands of tiny nozzles, which spray ink onto the paper with precise microscopic jets. Whereas laser printers use internal lasers to 'draw' the image onto the printer drum, which is then rolled through the toner and applied to paper using heat and pressure.

Computer storage solutions

If your laptop's struggling for space to save all your photos, videos and music, or you want a way to back up your laptop, then purchasing a memory card, flash or hard drive is your best option.

What is an SD card?

SD or Secure Digital cards are the most popular type of memory card format available. Their compact size and excellent transfer speed make them ideal for small portable devices, such as tablets and mobile phones.

There are 3 main types of SD media - SDHC, SDXC and microSD.

  • SDXC cards have a higher capacity than SDHC cards.
  • MicroSD cards are smaller versions (in physical size) of SDHC and SDXC cards.

USB flash drives

USB flash drives are great for storing smaller files like documents, photos and videos. You can get a 3.0 or 2.0 version. This refers to the speed of the USB interface of your device. Devices with USB 3.0 will transfer files faster than 2.0, but before you buy, make sure your device's port supports USB 3.0 or you won't see the benefit.

Solid state hard drive.

What is a SSD hard drive?

A solid state drive (or SSD) uses flash memory to store data. Think of them as simply a large version of a USB drive, as they use the same base technology.

What they're great for

  • They have good energy efficiency.
  • Fast loading times for games, films and other software.
  • They're lightweight and durable, so more likely to withstand being dropped or moved.

What is a HDD hard drive?

Hard disk drives (or HDD) are the most well-known hard drives. They use internal, magnetic spinning disks (sometimes known as platters) to read and write data.

What they're great for

  • They have much larger storage options.
  • They’re more widely available and tend to be lower in price.
  • They have long lifespans so, if looked after, they won’t need replacing as often.

Portable hard drives

Portable hard drives are a great way to store important documents, photos, videos and other files off your PC, laptop or gaming console. They tend to be lightweight and small in size making them easy to move, use and store away.
They range in capacity from the smaller 500GB and under, to the larger 1-2TB. And for those of you who need it, there are also some even bigger portable hard drives, that offer over 3TB of storage.

How big a hard drive do I need?

How big a hard drive do I need?

This generally depends on what you are planning to do. If you are planning to play games or store a lot of photos or videos, then a larger hard drive is what you'll need. For general use and document storage, hard drives under 500GB should be more than sufficient.

Here are the average sizes you would need for different content:

  • Music - 80 - 120GB
  • Software - 120 - 320GB
  • Videos - 320GB - 1TB
  • Gaming - 512GB - 2TB
  • 4K or HD videos - 1TB+
