The operating system of your PC determines the way it looks, how it works, and the type of software you can use. The three main operating systems are Windows, Apple OS X, and Chrome OS.

The processor is the brain of your PC and executes every command. Any software you buy gives a minimum set of requirements that the processor must meet or surpass. Our product pages give you all the info you need to find the right PC to run your programs.

Often mistaken for storage, RAM (Random-access Memory) is where your PC picks up your requests and makes them happen. More RAM allows the processor to take on more jobs at once - ideal for multitasking.

Your storage is the place where all your files (like documents, music, photos and software) go when you save them. There are two different types of storage for PCs – spacious hard disc drives (HDD) and super-fast solid-state drives (SSD).

From a compact 19'' to a huge 34'', there’s an all-in-one to suit any use. Smaller all-in-ones are great space-savers and give you the functionality of a desktop PC without sacrificing the space needed for a tower. Larger all-in-ones are great for films, editing media and multitasking.
