The motherboard is the central component of a computer that connects and allows communication between the CPU, RAM, and other hardware components. It allocates power and forms the foundation of the computer. Key parts of the motherboard include the CPU, BIOS, cache memory, expansion bus, chipsets, and CPU clock. Chipsets like the Northbridge and Southbridge help coordinate data flow between the CPU and other components like memory, graphics cards, storage devices, and input/output ports.

2. What is a Motherboard?
■ Alternatively referred to as the mb, mainboard, mboard, mobo, mobd,backplane
board, base board, main circuit board, planar board, system board, or a logic board on
Apple computers.The motherboard is a printed circuit board that is the foundation of
a computer, located on the back side or at the bottom of the computer chassis. It
allocates power and allows communication to the CPU,RAM, and all other
computer hardware components.

4. Chipset
■ A chipset is a group of small circuits that coordinate the flow of data to and from a PC's
key components.These key components include the CPU itself, the main memory, the
secondary cache, and any devices situated on the buses. A chipset also controls data
flow to and from hard disks and other devices connected to the IDE channels.
■ A computer has got two main chipsets:
■ 1)The NorthBridge
■ 2)The SouthBridge

5. NorthBridge
■ Northbridge is an Intel chipset that communicates with the computer processor and
controls interaction with memory, the Peripheral Component Interconnect (PCI) bus,
Level 2 cache, and allAccelerated Graphics Port (AGP) activities. Northbridge
communicates with the processor using the frontside bus (FSB).

6. SouthBridge
■ Southbridge is an Intel chipset that manages the basic forms of input/output ( I/O )
such as Universal Serial Bus ( USB ), serial , audio, Integrated Drive Electronics ( IDE ),
and Industry StandardArchitecture ( ISA ) I/O in a computer.

7. Data Base
■ A database is a collection of information that is organized so that it can easily be
accessed, managed, and updated. In one view, databases can be classified according
to types of content: bibliographic, full-text, numeric, and images.
