The computer case houses the internal computer components such as the power supply, motherboard, cpu, ram and hard drives.

Computer cases come in different form factors (sizes and layouts) such as horizontal cases, vertical towers, laptops and all-in-one varieties.

Power supplies convert AC power into the lower voltage DC power that is used by the internal components of the computer.

The motherboard is the backbone of the computer and all internal components are connected together through the printed circuitry on the motherboard

The CPU is also known as the brain of the computer is responsible for executing the computers commands and code.

RAM stores temporary data for programs accessed by the computer. RAM is volatile and is deleted when the computer is turned off.

Adding more RAM to a computer can enhance performance. Though the maximum amount of RAM usable is limited by the motherboard.

Internal storage devices are used for long term storage of personal data, system files, and software used on and by the computer.

Hard Disk Drive (HDD) is an internal storage device that uses mechanical parts and magnets to read/write data to the drives storage platter.

Solid State Drives (SSD) use integrated circuits and flash memory to store the data required and are typically faster then the older HDDs they replace.
