Common computer components

  1. 1. Common Computer Components
  2. 2. CPU This processes data that is received, and comes out with an outcome. For example, if 2 + 2 was put in, it would come out with 4. The speed of a CPU is measured in Mega hurtz. Without it, the computer will be limited to almost nothing, coming up with an error on the screen.
  3. 3. Hard Drive This stores and retrieves computer data and files. Constructed with a large rotating disk, with a magnetic rod that writes data to it. Without it, you cannot access or save files.
  4. 4. Power Supply This supplies power to different parts of a computer through it’s different cables (to motherboard, hard drive, optical drive etc.). The box though, is to convert alternating current to direct current. Without it, the computer would just not be able to turn on
  5. 5. RAM/ROM ROM is memory that cannot be edited or modified, it can only be read. It can be taken out and put back in a computer. RAM is memory that can be edited and modified, and is accessed randomly. Unlike ROM, It can’t be taken out and put back in a computer.
  6. 6. Motherboard Not specifically a component, but more like the main circuit board for the computer, connecting different devices together. It holds the CPU, adapter cards, BIOS, RAM and ROM.
