Inside your computer

The working parts inside

The processor, also called the CPU, carries out instructions. RAM is the computer’s temporary working memory for things it is using now. Storage, such as an SSD or hard drive, keeps apps and saved files when the power is off.

The graphics processor, or GPU, helps create the images shown on your screen. It may be built into another chip or fitted on a separate graphics card. The motherboard is the main circuit board connecting the parts so they can work together.

A power supply provides the electricity the parts need. Laptops also use a battery and a charger. Cooling, often including fans and metal heat sinks, carries heat away from working parts.

Working on something is different from saving it

RAM does not keep ordinary working data when power is lost. Saving a file puts its contents into storage. Having more RAM and having more storage space help with different needs.

Separate memory from storage

You are going to explore the main internal parts and distinguish memory from storage. Explore the labelled cards, then match each job to its part. Click Show me a hint if you need help with the matching questions.

Click or tap each named part to read its job. In the two questions below, match temporary current work and keeping saved files after power is off. Click the circle beside an answer, then click Check answer. For keyboard use, Tab reaches the choices, arrow keys change the chosen answer, and Tab then Enter activates Check answer.
