PC components explained: learn what each part does, their functions, and how CPU, GPU, storage, and cooling impact performance and longevity.

The main processor (CPU, “Central Processing Unit”), the main memory (RAM, “Random-Access Memory”), and the dedicated graphics card with its graphics processor (GPU, “Graphics Processing Unit”) are ...

In the eighties, computer processors became faster and faster, while memory access times stagnated and hindered additional performance increases. Something had to be done to speed up memory access and ...

We all know, at least intellectually, that our computers are all built with lots of tiny transistors. But beyond that it’s a little hard to describe. They’re printed on a silicon wafer somehow, and ...
