Internal Hardware

RAM (Random access memory) MOTHERBOARD CPU (Central Proccesing unit) SOUND CARD GPU POWER SUPPLY HARD DRIVE SSD (Solid State Drive)

For internal storage there are two options. SSD's and HDD's. SSD's are much faster than traditional Hard drives because there are no mechanic parts.

GPU's process all the stuff that require large video or image quality. They then send signals through cables to your monitor.

The motherboard is the board which connects every single component of the PC.
