  • 1. The Basics of Computer Components
    by James Broadberry
  • 2. What I will cover
    Processor
    RAM
    Hard Disk Drive
    Graphics Card
    Power supply
    Motherboard
  • 3. Processor (CPU)
    Brain of the computer
    Controls everything that goes on
    Every piece of information will go through the processor.
    Every piece of logic is applied at the Processor
    Speed of the processor is how many times the information can “cycle” through the processor.
  • 4. RAM
    Temporarily stores information
    Gets information to the processor without wasting/delaying clock cycles.
    When the computer is turned off, the data stored in the RAM is erased
    Adding more RAM will let more applications run faster
  • 5. Hard Disk Drive (HDD)
    All files are stored on the Hard Drive
    Slower than RAM but can hold more, permanently
    The Operating System is stored on the Hard Drive
  • 6. Graphics Card (GPU)
    Generates signals to be sent to the monitor/screen
    Amount of pixels generated depends on the speed of the GPU and screen size
    The rate that the pixels are “re-generated” or “refreshed” are measured in Hertz
  • 7. Power Supply (PSU)
    Converts AC to DC
    Power supplies for standard workstations are normally output about 350 Watts
    Divide power up for safe use
  • 8. PSU Connectors
  • 9. Motherboard
    All of the computer components are connected to it
    Distributes power to the processor and RAM
    Sends information between the Processor and the RAM
    Gets between 30-40 degrees while doing nothing with correct cooling
  • 10. What goes where?
  • 11. Recap
    Motherboard connects every component to each other
    The processor does all of the logic
    RAM stored information temporarily at very high speeds
    Hard Drives store information permanently
    Graphics Cards are used to generate a signal to be read and understood by a monitor
    The power supply divides the power between each component
