A laptop combines a screen, keyboard, battery and computer in one portable device. Its suitability depends on the software you need to run, so check your course requirements before choosing one.
- Processor: carries out instructions and affects how quickly tasks run.
- RAM: helps when several applications or browser tabs are open.
- Storage: provides space for the operating system, applications and files.
- Screen and battery: affect comfort and portability.
Inside a desktop PC
| Component | What it does |
|---|---|
| CPU | Processes instructions and calculations. |
| Motherboard | Connects components so they can communicate. |
| RAM | Temporarily holds data for active tasks. |
| SSD or hard drive | Stores files and applications when the power is off. |
| GPU | Processes graphics for the display; it may be integrated or a separate card. |
| Power supply | Supplies suitable electrical power to the components. |
| Cooling | Helps remove heat from components. |
Useful peripherals
A keyboard and mouse provide input, a monitor displays output, and a headset supports audio and calls. A webcam can help with online lessons, while an external drive can hold a backup of important files.

RAM temporarily holds data for tasks in use. Storage keeps files and applications when the computer is switched off. They have different jobs.
The CPU handles a wide range of instructions and calculations. The GPU is designed to process graphics and other tasks that can use many parallel calculations.
Components produce heat as they work. Heatsinks and fans move heat away so components can operate within their intended temperatures.
