  2. Motherboards The Main Printed Circuit Board Inside The PC That Contains and Controls The Components That Are Responsible For Processing Data.

  3. Motherboard is • Multi-layered printed circuit board • Copper circuit paths called traces carry signals and voltages across the motherboard • Some layers carry data for input/output while other layers carry voltage and ground returns

  4. CPU type and speed Chipset Secondary cache type Types of Expansion slots Number of Expansion slots Type of memory Number of memory sockets and maximum memory Type of case ROM Plug & Play compatibility Type of keyboard Motherboard Determines:

  5. Motherboard Components LPT 1 Printer Port PS/2 Mouse& Ps/2 Keyboard Connector AGP Expansion Slot USB Port Power Connector PCI Expansion Slots CPU Socket Memory Sockets BIOS Chip ChipSet Floppy Drive Controller CMOS Battery

  6. AGP Expansion Slot (Accelerated Graphics Port) A high-speed port developed by Intel that is designed for the display adapter (video card) only. It provides a direct connection between the card and memory, and only one AGP slot is on the motherboard. AGP uses a 32-bit bus and is generally brown in color.

  7. CMOS Battery A battery that maintains the time, date, hard disk and other configuration settings in the CMOS memory.

  8. BIOS Chip • BIOS Basic Input /Output system- The BIOS, or Basic Input/Output System, provides low-level access to the computer's hardware. The BIOS resides on a chip on the motherboard

  9. PCI Expansion Slots • Peripheral Component Interconnect) A peripheral bus commonly used in PCs, Macintoshes and workstations • PCI provides "plug and play" capability, automatically configuring the PCI cards at startup • PCI runs at 33MHz, supports 32- and 64-bit data paths and bus mastering • PCI expansion slots are also identified by their white color.

  10. Primary and Secondary IDE Controller • (Integrated Drive Electronics) A type of hardware interface widely used to connect hard disks, CD-ROMs and tape drives to a PC. • Today, two Enhanced IDE (EIDE) sockets are built onto the motherboard, and each socket connects to two devices via a 40-pin ribbon cable.

  11. Floppy Disk Drive Controller Back • A 34 pin adapter on the Motherboard that attaches to the controller.

  12. DIMM Memory Modules • (Dual In-Line Memory Module) A printed circuit board that holds memory chips and plugs into a DIMM socket on the motherboard • DIMMs (dual in-line memory modules) doubles the number of paths between the module and motherboard by using each side of the edge connector independently.

  13. CPU Socket • A device designed to attach the Central Processing Unit (CPU) to the Motherboard’s internal circuitry

  14. ATX Power Connector • A 20 pin connector used to supply power the motherboard components.

  15. PS/2 Mouse and Keyboard Connector Back • A 6-pin Mini-DIN plug and socket used to connect a keyboard and mouse to a computer.

  16. LPT 1 Printer Port • In a PC, the logical name assigned to parallel port #1. The parallel port is typically used for the printer. A second parallel port, if installed, is assigned to LPT2.

  17. Com1 and Com2 Ports • In a PC, the logical name assigned to the first serial port. Two serial ports, or COM ports, are provided on a PC to connect a mouse and modem. Typically the mouse is on COM1, and the modem on COM2.

  18. ChipSet • A set of chips that provides the interfaces between all of the PC's subsystems. It provides the buses and electronics to allow the CPU, memory and input/output devices to interact.

  19. Universal Serial Bus (USB) • Universal Serial Bus) A hardware interface for low-speed peripherals such as the keyboard, mouse, joystick, scanner, printer and telephony devices. • USB's hot swap capability allows everything to be plugged in and unplugged without turning the system off.

  20. Motherboard with SATA

  21. Baby AT Motherboard • A smaller motherboard (9x10") that superseded the one used in the original IBM AT (12x13.5"). The Baby AT motherboard has been widely used in 386, 486 and Pentium PCs.

  22. ATX Motherboard • A motherboard that superseded the widely-used Baby AT design. ATX rotates the CPU and memory 90 degrees, allowing full-length boards in all sockets. The power supply blows air over the CPU rather than pulling air through the chassis.

  23. NLX Motherboard • An Intel motherboard used for NetPCs and other low-profile (space-saving) systems. Introduced in 1997, NLX supports the AGP and uses a riser card for expansion boards.

  24. The references • Paul Miller. "Apple sneaks new logic board into whining MacBook Pros" (2006). Engadget. • “Mobo” Webopedia. Retrieved 2008-10-23. • c't Magazine, vol. 21, pp. 216-221. 2003.
