Central Processing Unit: Also referred to as “the processor”, a central processing unit (CPU) is the brains of your computer. Generally, the larger a CPU and the more cores a computer has, the faster it will run. CPU power is measured in GHz and a good CPU should be 1.4GHz or larger.
Cores: Cores allow the CPU to multitask functions. The more cores a CPU has, the more tasks it can complete at the same time, though the number of cores is not proportional to the number of tasks.
Graphics Processing Unit: A graphics processing unit (GPU) frees up the CPU by taking care of the graphics tasks. Unlike CPUs, GPUs aren’t rated by GHz. GPU performance is often affected by how much RAM is available. Some computers have dedicated RAM for the GPU.
HDD & SSD: The hard disc drive (HDD) is where data is stored on your computer, apart from files you store on the cloud. There are two common types of hard drive; Standard (referred to as hard disc drive – HDD) that has a spinning disk inside and solid state drives (SSD) that are a series of memory chips. A hard drive of 300GB or more should be sufficient for the average user. If you work with images, videos, other large files or use lots of software, then you should consider more storage, at least 1TB.
RAM: A processor needs random access memory (RAM) to temporarily store relevant data about its current tasks. RAM helps a processor perform to its optimum.
