All the computers have the same inside, does not matter if its desktop or laptop.

To make it simple, here I am only going to talk about the grafics card(GPU), processor (CPU) and about the RAM.

-> First we have the GPU and that means Grafics Process Unit.
A programmable logic chip (processor) specialized for display functions. The GPU renders images, animations and video for the computer's screen. GPUs are located on plug-in cards, in a chipset on the motherboard or in the same chip as the CPU.

-> Then we have the CPU that translate to Central Processing Unit.
The CPU (processor) is one of the most important components in a computer, it can be likened to the brain of the system. There are 2 main PC CPU manufacturers, Intel and AMD.

-> To finish we have the RAM that is Random Access Memory
RAM (Random Access Memory) is the hardware in a computing device where the operating system (OS), application programs and data in current use are kept.
