Internal components

CPU

The Central Processing Unit — carries out the instructions of every programme you run. It's the "brain" of the computer.

RAM

Random Access Memory — short-term memory that holds what the computer is working on right now. It's cleared when the computer turns off.

HDD / SSD

Long-term storage that keeps your files even when the power is off. SSDs (Solid State Drives) are faster than older HDDs (Hard Disk Drives).

GPU

The Graphics Processing Unit — handles images, video and games, so the CPU doesn't have to do it all.
