  1. 1. WELCOM TO What is Motherboard?
  2. 2. What is Motherboard | Definition Uses and Functions • A Computer Motherboard is commonly known as Main board or MB or System board or logic board is designed on PCB (Printed Circuit Board).That holds or connects all components and parts together on a single sheet. The Computer Motherboard holds all the circuitry to connect the various components of a computer system. Therefore it is also called as backbone of Personal computer system • The Main board or Motherboard is the main crucial and important part of the computer system. It holds many important components such as computer memory slots,cpu,sata IDE slots, expansions slots(PCI,AGP etc),capacitor’s, resistor’s ,BIOS chip etc. The Computer main board is made up of thin sheet of non conductive material from plastic .The traces which are present on the motherboard is made up of copper/aluminum foil. There are many companies which manufacture excellent quality of logic boards these day's such as Intel, Asus, Gigabyte,Msi, Asrock, Sapphire technology, Biostar etc
  3. 3. Computer Motherboard Label Diagram
  4. 4. Components and parts Used in Computer Motherboard • There are various component embedded in MB/PCB(Printed Circuit Board).You should know the basic computer functionality and uses of the various component attached to main board to use it and installed in Computer case. • Today Computer Motherboards comes in number of variety but the basic functionality and uses are pretty much the same? You must be familiar with the use and aware of the basic architecture of PC and Laptop motherboard design • As it is difficult to understand each and every part of MB still you should be aware of some common and important component & parts attached to it.
  5. 5. List of component of PC Motherboard • Expansion slots (PCI Express, PCI, and AGP) • 3-pin case fan connectors • Back panel connectors • Heat sink • 4-Pin (P4) power connector • CPU Socket • Screw hole • Memory slot • Floppy connection • ATA (IDE) disk drive primary connection • 24-pin ATX power Supply connector • Serial ATA connections • Coin cell battery (CMOS backup battery) • System panel connectors • Serial port connector • USB headers • Jumpers • SPDIF • Game port and MIDI header • Internal speaker • Keyboard controller • Parallel port header • PS/2 header
  6. 6. PC Motherboard Component and Their Features Ps/2 Mouse Port Ps/2 Keyboard Port • Ps/2 Keyboard Connector • Circular In Shape • 6 Pins • Female Type Of Connector • Usually Voilet In Colour • Ps/2 Mouse Connector • Circular In Shape • 6 Pins • Female Type of Connector • Usually Green In colour

  9. 9. Complete Description of Computer Motherboard • The desktop or PC motherboard is mounted inside the computer case with the help of small screws which are used to tighten the system board into the computer case . The computer case possess some pre-drilled holes so that the screws can be easily fit into it. • System or Main board consist of a single CPU socket which is pre-soldered into it. There are various types of CPU socket which are used to determine the computer motherboard and the CPU which is compatible with it. • Expansion slots are used in motherboard so that you can install additional video cards, sound cards, and graphic cards into it. These expansion slots are pre-install.
