### Motherboard
The motherboard houses many of the crucial electronic components of a system, such as the central processing unit (CPU), memory and extension cards. It also provides electrical connection between these compoenents and other peripherals so they can communicate.

### Expansion Cards (eg. GPU) ### Expansion Cards (eg. GPU)
An expansion card is an embedded circuit card that can be added to the motherboard to augument a computer's capability. It can either add capabilities, ex allow for a new type of I/O port, or upgrade existing ones, ex. faster ethernet connection. The most common type of expansion card is a GPU, or a graphical processing unit. Expansion cards are printed circuit board that can be inserted into a computer motherboard to add functionality to a computer system via the expansion bus.
An example of extension cards is the GPU. A graphics processing unit (GPU) is a specialized electronic circuit designed to rapidly manipulate and alter memory to accelerate the creation of images in a frame buffer intended for output to a display device.

### Memory (RAM) ### Memory (RAM)
Random-access memory (RAM) is a form of computer data storage which stores data and machine code currently being used. A random-access memory device allows data items to be read or written in almost the same amount of time irrespective of the physical location of data inside the memory.

### Power Supply ### Power Supply Unit (PSU)
A power supply is an electronic device that supplies electric energy to an electrical load. A computer power supply supplies electrical energy to all the components of the computer including: the motherboard, disk drives, and fans. Power supplies vary in the amount of output they provide and power supplies must be matched to the number of components needing power so they are not overloaded.

A computer power supply supplies electrical energy to all the components of the computer including: the motherboard, disk drives, and fans. Power supplies vary in the amount of output they provide and power supplies must be matched to the number of components needing power so they are not overloaded. The PSU changes alternating current from a wall socket to low-voltage direct current to operate the CPU and peripheral devices.
