motherboard

• The motherboard is a printed circuit board containing principal components of a computer or device, with connectors for other circuit boards
• Component Parts of the Motherboard:

  • CPU slot or socket: where the microprocessor is installed (e.g. Intel® Core i5, AMD Radeon)
• • CMOS battery: supplies power to store BIOS settings and keep the real-time clock running
• • Northbridge with heatsink: chipset allowing CPU to communicate with RAM and graphic card
• The CPU is the brain of the computer, controlling all other components.
• • RAM slot: where the DRAM memory module is installed (e.g. DDR SDRAM, DDR2, DDR3)
• • IDE/HDD controller: connects hard disk drive and optical drive for data transfer
• • FDD controller: used to attach floppy disc drive
• • SATA controller: connects hard drive, solid state drive, optical drives for data transfer
• • AGP slot: high-speed channel for attaching a video card
• • PCI slot: allows attachment of hardware components like network cards, modems, sound cards
• • Fan header: supplies power to the CPU heat sink fan and computer case fans
• • ATX power connector: connects to the 24-pin ATX power cable of a power supply unit to supply power to the motherboard
• • I/O peripheral port: connects peripheral devices into other parts of the motherboard
• • Southbridge chipset with heatsink: allows CPU to communicate with PCI slots, SATA connectors, USB ports, Ethernet ports, and on-board audio
• • ATX 12 V power connector: connects to power supply unit to supply power to the CPU
• • Front panel USB 2.0, USB 3.0 connectors: connects to USB ports at the front or top of a computer case
• • Front panel connectors: power switch, reset switch, power LED, hard drive LED, front audio ports of a computer case
• ATX : 12x9.6 inches
• Micro ATX : 9.6x9.6 inches
• Mini ITX : 6.7x6.7 inches
• A Single Edge Contact Cartridge (SECC) is a central processing unit (CPU) component designed to hold certain Intel microprocessors such as Pentium II and Pentium III, Pentium Pro and Celeron.
• The SECC is also known as Slot 1 because it is inserted into Slot 1 on the motherboard.
• Intel leaves the pins on the motherboard, and the CPU has a set of contacts on the underside of the processor.
• AMD the pins are on the CPU, while the socket is a set of holes that the CPU slots into.
• Intel uses a retention bracket and latch with the bracket partially covering the seated CPU.
• BGA is a surface-mount packaging type where solder balls are configured in a grid-like pattern on the bottom of a component. These solder balls create electrical connections between components and the PCB board. BGA packages are the main part of microprocessors, integrated circuits, and other complicated electronic components.
