Best Answer

Motherboard

connects all the pieces together

Hard Disk

long term memory,stores everything, including files, data...etc

advantage over RAM: data remains even after the computer shuts down.

Disadvantage: Very slow compared to RAM

RAM

(stands for Random Access Memory)

short term memory - When data is needed it is loaded from the hard disk to the RAM for much faster processing.

Advantage over hard disk: Much faster

Disadvantage: loses data when computer shuts down

CPU

(Central Processing unit)

The "brain" of your computer, allows it to "think"

Graphics card:

Helps the CPU in processing graphics.

Example of these components working together:

1. A user opens up a video game ()

2. The CPU processes the click, and loads the video game from the hard disk to the RAM.

3. The user starts playing, the CPU and the Graphics Card now process everything in the game (player movement, environment, etc...)

4. when the player finishes, the data is removed from the RAM.

*of course, the component that connects all these things together is the motherboard

Note that there are a lot more components such as the power supply, Cd drives and more...
