    Computer programming instructions that are stored in a read-only memory unit rather than being implemented through software.

    Firmware is hardware-based software, hence the name.

    Almost any electronic item that contains a processor will have firmware - it's the basic programme that tells the device what to do when you press a button, insert a disk, switch on at the mains, etc.

    The firmware is stored in a non-volatile memory chip, which is a chip that doesn't lose it's contents when you disconnect the power supply. Many devices have chips that can be reprogrammed, either by service engineers, or by the customer.

    For computers and DVD players, you download the firmware from the net, copy it to a disk, and run a small program that copies the contents of the disk to the memory of the device. Sometimes the copying program is part of the firmware file, so you just have to insert the disk and reboot the device.

    Devices like TVs, PVRs and mp3 players obviously can't read a disk, so the firmware has to be updated using a PC.
