Hard Drives/SSD

A hard drive stores all the software, documents, photos and videos on a metal disc. Without this, the computer wouldn’t work, as you would need to download software in the computer to make it work. These days technicians are making new, better, smaller and more efficient hard drives(SSD).

SSD’s are solid state drives, which have no moving parts in them. They are much smaller, lighter and more effective however, because of their abilities; they are sufficiently more expensive than normal hard drives.

CPU (Central Processing Unit)

The Central Processing Unit (CPU), contains a part of the computer called the microprocessor. The microprocessor is the brain of all the computers operations and the whole performance of hardware and software relies on this one part of the computer. This is arguably the most important part of the computer. There are two common types of CPU: 64bit and 32bit, however it depends on the manufacturer.


The motherboard in your computer, laptop, smartphone etc. is the place where nearly every component is found. Everything connencts to it in some way or another. Most of the devices on this page are removablefrom the motherboard so the person can upgrade however, most of the important ones are stuck on them.


The RAM or Random Access Memory is compulsory to have in your computer if you would like it to be fast. It is needed so it stores temporary information when loads of programes are running so the processor can be much faster and morre efficient whilst working. The higher the ample amout (how much it stores) of RAM, the faster your computer will be when running software.
