1. Motherboard, Motherboard Contents and Its Functions
Motherboard is a also one of the important parts of the CPU. It is a Main Circuit board.
Motherboard connects all the parts of CPU. Motherboard Consist of Processor Socket,
RAM slots, PCI slots, AGP slot, IDE connectors and Ports.
Mecury 845 Chipset Motherboard
Every motherboard has connectors and slots to connect all the remaining parts of CPU.
Here the list of all the slot and connector of motherboard.
1. CPU Socket
2. North Bridge
3. South Bridge
4. RAM Slots
5. AGP Slot
6. PCI Slots
7. Floppy Connector
8. Primary and Secondary IDE Connectors
9. SATA connectors
10. Power Connector
11. BIOS
12. CMOS battery
13. Ports

2. 1. CPU Socket:
LIF socket or slot type processor socket ZIF socket or PGA sockets
CPU Socket or Processor Socket. This is used to install or insert the processor. We
have two types of sockets. LIF sockets and ZIF socket. LIF stands for Low Insertion
Force, this is the old model sockets and ZIF stands for Zero Insertion Force, this is the
present model sockets.
2.North Bridge:
North Bridge is always near the
processor socket. This is one of the
important components of a
motherboard. It is a focal Point of
Motherboard and It is also called as
Memory Controller Hub. North Bridge
interconnects Processor socket, RAM
slots and AGP slot. Here Gigabyte chip
is North Bridge it is near Processor
socket.
3.South Bridge:
North Bridge and south
bridge are the two main poles
of a motherboard. South Bridge
interconnects Primary and
Secondary IDE interfaces,
SATA connectors, Floppy Drive
Connector, PCI slots and BIOS.

3. 4.RAM Slots:
RAM slots are used to insert
RAMs. there are so many types of ram
slots. they are SD ram slots, DDR ram
slots, DDR2 and DDR3 ram slots. SD
stands for synchronize Dynamic and
DDR Stands for Double Data Rate.
5.AGP slot:
AGP slots are used to insert or
install AGP Cards. AGP full form is
Accelerated Graphics Port. This slot
is for graphics and 3d gaming
purpose. It is always beside the PCI
slots.
6.PCI slots:
PCI slots are used to Insert or
install Add-on cards, such as LAN
cards, Sound cards, Capture cards
and TV tuner cards. PCI full form is
Peripheral Component Interconnect.

4. 7.Floppy Drive Connector:
Floppy Drive Connector is used to connect
floppy drives. It supports two floppy drives. So
that A and B drives are reserved for two floppy
drives in My computer. It has 32 pins.
8. Primary and Secondary IDE Interfaces:
Primary and Secondary IDE
interfaces are also called as IDE
connectors or PATA connectors. IDE
full form is Integrated Device
Electronics. It supports IDE devices,
such as Hard disks and CD and DVD
drives.
9.SATA Connectors:
SATA connectors are also called as
Serial ATA connectors. SATA full form
is Serial Advanced Technology
Attachment. These are connect with
serial ATA devices, such as Hard disk
drives and CD or DVD drives.

5. 10. Power Connector:
This power connector is ATX power
connector. It has 20 or 24 pin
connector. Mother takes the power
from this connector to work.
11. BIOS:
BIOS stands for Basic input and Output system. This
is also one of the important chips. it conducts the POST
(Power On Self-Test).
12. CMOS battery:
There is a battery in the motherboard, which
is used to power the south bridge and the BIOS to
save the setting, data and time.
13. Ports:
Ports are used to connect input and
output devices. they are attached and
come with motherboard and they are in
backside of CPU.
