- - - - The computer's main memory is its RAM. When we run an application, its instructions and data are copied to this memory so that the microprocessor can use them. This is because accessing the hard disk is very slow. Since RAM doesn't retain information when the computer is switched off, we must save our work to the hard disk before we close the application. Otherwise we'll loose our work.
    - - RAM cannot work at the same speed as the microprocessor, so a much faster memory is installed between the RAM and the microprocessor, the cache memory. The cache memory stores the data the microprocessor uses most often.
    - - When you turn on your computer, it automatically checks the system. This initial check is carried out using instructions stored in a special read only memory: the ROM BIOS. If everything is correct, the BIOS starts the operating system in the main memory, so that this system can take control of the computer.
  - - - Slots can be used to expand or add new component, such as a modern, sound card, network card and so on. These slots can be PCI (peripheral component interconnect) or PCI-express.
      - The IDE or ATA and SATA connectors. Connect the hard disk, CD drive and DVD drive to the motherboard.
