3. WHAT IS A MOTHER BOARD?
 It is PCB[printed circuit board]
 Hold components cpu,ram, connector
for i/o device, many slots.
 Heart of the computer system

4. CENTRAL PROCESSING UNIT[CPU]
CPU
ALU
[arithmetic
logic unit]
CU
[control unit]
MU
[memory unit]

5. CPU SOCKET
It provides mechanical and
electrical connection between a
Microprocessor and printed
Circuit board.

6. HEAT SINKER
*It helps to reduce the
heat Of CPU
* heat sink are usually made
from metal bcoz metals have high
thermal conductivity. like aluminum

7. RANDOM ACCESS MEMORY [RAM]
 Randomly access
 Volatile memory
 Static ram[S-RAM]
 Dynamic ram[D-RAM]
 ddr1 ,ddr2, and ddr3 ram.

8. DIFFERENCE BETWEEN S-RAM & D-RAM
 type of semiconductor
memory that uses bits
able latching circuitry to
store each bit.
 L2 and L3 cache in a
CPU
 Size 1 MB to 16 MB
 Consume less power
 Expensive
 stores each bit of data
in a separate capacitor
within an integrated
circuit
 Main memory in a
computer. EX- DDR3,
DDR2
 Size 2,4,8,16 GB
 Need power
 cheap
S-RAM D-RAM

9. DUAL IN LINE MEMORY MODULE
 168-pin DIMM, used for SDR SDRAM
 240-pin DIMM, used for DDR2 SDRAM, DDR3
SDRAM and DRAM

10. READ ONLY MEMORY[ROM]
ROM
PROM EPROM EEPROM

11. BASIC INPUT OUTPUT SYSTEM[BIOS]
 * It manages data flow between the computer's
operating system and attached devices .
 *Power On Self Test [POST]
 * For enter BIOS press f8,f2,
del etc.

12. NORTH BRIDGE
 *Northbridge is an Intel chipset
 *communicates with processor and controls
interaction with ram, the Peripheral Component
Interconnect (PCI) , L2 cache, and Accelerated
Graphics Port.

13. SOUTH BRIDGE
It controls components like-
*ATA Drive
*USB bus
*Serial port
*Parallel port
*Built-in audio

14. PCI -SLOTS
 It is a parallel bus, synchronous to a single bus
clock
 an expansion card that fits into a slot.

15. EXPANSION CARD FOR PCI- SLOTS
 Ethernet card Sound card

16. AGP-SLOT
 high-speed point-to-point channel for attaching a
video card
 For advance graphical
works
 Best gaming performance
 SLI and
CROSSFIRE-X

17. ZOTAC NVIDIA GTX 660 TI
GRAPHIC CARD

18. CMOS BATTERY
 Metal oxide semiconductor
 Store BIOS setup
 Long lasting up to
3-4 years

19. SATA AND PATA
 Serial
 600 MB/s
 0.25 volts
 0.25 inches
 hot pluggable
 Parallel
 133 MB/s
 5 volts
 2 inches
 Not hot pluggable
SATA PATA

20. Sata cable Pata cable

21. ATX-PORT & P4-PORT
 Power supply to
whole mother board. Dedicated
pin-24 power supply for
 Power come from SMPS processor.
