  1. Computer basics How to build your own pc

  2. Choosing parts • Motherboard • Processor • Memory (RAM) • Disk drive • Graphics card • Power supply • Case • Blu-ray/DVD drive • Cooling • Operating system

  3. motherboard • Most important component • Links all other parts together and supplies them with power • Motherboard and processor must be compatible

  4. processor • The “thinking” part of the computer: makes all decisions and calculations • Controls all other components • Processor socket must match motherboard socket

  5. Memory (RAM) • Computer’s short term memory • Stores programs and files while they’re being used • Both processor and motherboard must be compatible with your RAM • 4GB or more is enough for most users

  6. Disk drive • Stores files and programs long term • Can be hard disk (HDD) or solid state drive (SSD) • HDDs are slow, but store more and are cheaper • SSDs are much faster, but are smaller and more expensive

  7. Graphics card • Generates everything seen on screen • Graphics processing unit (GPU) is optimized for drawing graphics • Optional, as most processors include a rudimentary GPU • High-end GPUs are very expensive

  8. Power supply • Provides power for the entire system • Capability is measured in watts • 300W or more is sufficient for most users

  9. Cooling • Keeps the processor cool • Additional fans throughout the case keep air flowing

  10. Blu-ray/Dvd drive • Plays Blu-rays, DVDs and CDs • Optional, as optical media is used increasingly less

  11. case • Holds all components • Directs airflow to help keep everything cool

  12. Operating system • The software that runs everything • When building a PC, you can choose between Windows and Linux • Popular versions of Linux include Ubuntu, Mint, Fedora, and Debian
