Computer basics

How to build your own pc

choosing parts
Choosing parts
  • Motherboard
  • Processor
  • Memory (RAM)
  • Disk drive
  • Graphics card
  • Power supply
  • Case
  • Blu-ray/DVD drive
  • Cooling
  • Operating system
motherboard
motherboard
  • Most important component
  • Links all other parts together and supplies them with power
  • Motherboard and processor must be compatible
processor
processor
  • The “thinking” part of the computer: makes all decisions and calculations
  • Controls all other components
  • Processor socket must match motherboard socket
memory ram
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
disk drive
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
graphics card
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
power supply
Power supply
  • Provides power for the entire system
  • Capability is measured in watts
  • 300W or more is sufficient for most users
cooling
Cooling
  • Keeps the processor cool
  • Additional fans throughout the case keep air flowing
blu ray dvd drive
Blu-ray/Dvd drive
  • Plays Blu-rays, DVDs and CDs
  • Optional, as optical media is used increasingly less
slide11
case
  • Holds all components
  • Directs airflow to help keep everything cool
operating system
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
