  2. What Is Motherboard ? • The large circuit board found inside the computer. • 1) It is the main circuit board of a computer. • 2) It controls all the physical devices and components that are connected directly or indirectly. • 3) CPU, RAM, Hard-disk, DVD RW, CPU FAN, Expansion cards are connected to it. • 4) Motherboard comes in different form-factors. Type’s, Size,

  3. AT Motherboard ATX Motherboard

  4. Components on the Motherboard 1. Processor Slot/socket 2. Memory Slots 3. Expansion Slots 4. I/O Ports 5. Chipsets 6. IDE or PATA/SATA Connector 7. CMOS Battery 8. Power Supply Connector 9. Heat Sink 10. Front Panel Connector

  5. Back Panel Connectors 1. PS/2 (Personal System v2) It is 6 pins female port/Connector. Used to connect keyboard / mouse. 2. USB (Universal Serial Bus) Used to connect various USB enabled devices. (Keyboard, mouse, pen drive, external Hard disk, etc…) 3. VGA (Visual Graphic Adapter ) It is 15 pins female connector Used to attach monitor, projector & TV 4. Serial port (Com Port) It is 9 pins male connector Used to connect cisco router or switches etc… 5. LAN Port: (Ethernet Port) Used to connect PC to Local Area network.

  6. Back panel connector 6. LPT Port (Line Print Terminal) It is 25 pins female connector. Used to attach Dot. Matrix printer. 7. Sound Port It is used to attach speaker & mic.

  7. Chipset 1.North Bridge : -it controls the Processor and RAM (High speed devices) -it is placed nearer to the processor -it also contains graphic processor -it is also called as GMCH (Graphic Memory Controller Hub) 2. South Bridge: -it controls low speed devices like I/O ports, slots etc… -it is placed nearer to the slots. -it is also called as IOCH (Input Output Controller Hub)

  8. IDE / PATA and SATA Connector IDE (integrated drive electronics)/PATA(Parallel advance technology attachment) • IDE/EIDE cables are used to connect the devices the connector • It is 40 pin’s connector used to attached or connect hard disk, dvd r/w. SATA (Serial advanced Technology Attachment) • SATA cables are used to connect the devices to the SATA • It is pin less connector used to attached or connect hard disk, dvd r/w. FDD Port(Floppy disk Drive) • It is 34 pin connector or port used to attached floppy disk drive.

  9. IDE / PATA and SATA Connector ISA Slot(Industry Standard Architecture) • Its is used attached sound card ,LAN card VGA card . • Speed 4.77 MHz and 8 bits /16 bits support . PCI Slot(Peripheral Component Interconnect) • Its is used attached sound card ,LAN card VGA card . • Speed 33MHz and 32 bits /64 bits support . AGP(Accelerated Graphics Port) • Its is used attached graphics card . • 24 bits support

  10. IDE / PATA and SATA Connector PCIE Slot(Peripheral Component Interconnect Enhance ) • Its is used attached graphics card. • 32 bits /64 bits support .

  11. CMOS Battery • CMOS (Complementary Metal Oxide Semiconductor)Rom is used to store the Date, time and system configuration. • Battery which powers this memory is called as CMOS Battery

  12. Series of Motherboard

  13. Manufacturer of Motherboard Chipset Manufacturer Intel MSI Via

  14. BIOS • During the boot up it performs POST (Power On self-Test) • Recognizes the hardware devices • Locates and loads the operating system • It helps the operating system to access the hardware devices.
