|
### 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.

|
|
|
|
|
|
|
|
### 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.
