MOTHERBOARD
A motherboard is the physical arrangement in a computer that contains the computer's basic circuitry and components. On the typical motherboard, the circuitry is imprinted or affixed to the surface of a firm planar surface and usually manufactured in a single step. The most common motherboard design in desktop computers today is the AT, based on the IBM AT motherboard. A more recent motherboard specification, ATX, improves on the AT design. In both the AT and ATX designs, the computer components included in the motherboard are:
The microprocessor
(Optionally) coprocessors
Memory
basic input/output system (BIOS)
Expansion slot
Interconnecting circuitry
Additional components can be added to a motherboard through its expansion slot. The electronic interface between the motherboard and the smaller boards or cards in the expansion slots is called the bus.
DRIVERS
The drivers are softwares needed to run a hardware such as the printer, the monitor, or the scanner properly. The drivers also usually come pre-installed in your new computer. When you run your computer the first time, you may have to configure the correct driver for your brand and model of hardware, such as the printer. But if you buy say, a new printer later, you may have to get a new driver for your new printer from the printer manufacturer. The manufacturer may send you the new driver in the form of floppy disk(s), or you may have to download the driver from the manufacturer's web site. Sometimes the new driver comes packed with the new device in the form of a floppy disk. You just have to install it. Sometimes even for your old device, a better driver may be available from that device's manufacturer. Check the device manufacturer's web site for the latest information.
