This firmware is the area of ​​computer science and computer engineering, which is rarely known by the general user.Computers in general is a personal computer (PC) in the form of a desktop or tower case consists of the following:

    System board / parent who holds the CPU, memory, vga slot, and has slots for additional cards.
        RAM - where to store temporary data / short term, so the software we run is stored temporarily, so the computer does not have to always access the hard disk for data. Larger amounts of RAM will help speed your PC
        Buses:
            PCI Bus
            ISA Bus
            USB
            AGP
        ROM (Read Only Memory) in which the firmware is placed

            DVD-RW
            DVD-R
        Floppy disk
    In storage - storing data in a computer for long term use.
        Hard disk - for long-term data storage
        Disk array controller
    Sound card - translates signals from the system board into which can be understood by the speaker, and has terminals to plug in speakers.
    Networking - to connect to the Internet and / or other computers.
        Modem - media connecting to the internet connection.
        Network card - for DSL / cable, and / or connect to another computer.
