Computer Components

Computer Components

1. Fan - Cools the components that may get hot

2. RAM - Stores data while powered

3. CPU - Processes information

4. Motherboard - Connects all components

5. Power Supply - Supplies power to the components

6. Floppy Drive - reads and writes information from floppy drive

7. Optical Drive - Reads and writes data stored on compact disks

8. Hard Drive - Reads and writes data onto metal platters

9. Fetch - the instruction is understood from the memory to the CPU

   • Decode - the instruction is understood by the CPU
     • Execute - the instruction is carries out
   • The information is fetched from the RAM.

10. 1 Kilohertz - 1000 cycles per minute

    • 1 megahertz - 1,000,000 cycles per minute
    • 1 Gigahertz - 1,000,000,000 cycles per minute

11. RAM - Random Access Memory

    • ROM - Read-only memory
      • CPU - Central programming unit

12. ROM - Stores the instructions and data which is used when the computer 'boots up' whether or not it has power. It keeps the data whether or not it has power.

13. The difference between RAM and ROM is that RAM only contains the data and files only while powered but ROM contains the data whether or not it is powered. ROM is meant for permanent storage and RAM is meant for temporary storage.

14. Hard disk -
