  • @@CPU@@
    • Central Processing Unit
    • It must be compatible with the motherboard
    • The two different types of CPU sockets are PGA (Pin Grad Array) and LGA (Land Grid Array)
    • PGA: Pins are located on the processor itself
    • LGA: Pins stick out on the motherboard itself
    • CPUs are prone to overheating
    • Include a heat sink which takes the heat from the CPU and dissipates it through a fan or other medium

      • DRAM (Dynamic Random Access Memory)
      • A common form of RAM
      • DIMM ( Dual Inline Memory Module)
      • A type of RAM
    • SDRAM (Synchronous DRAM)
      • Type of RAM synchronized to our systems clock speed, allowing for faster processing of data
      • Faster RAM means programs can be run faster and more programs can run at the same time
