Onboard Components of a Motherboard

Onboard Components of a Motherboard Motherboard has several components that are a part of it. These components are sockets, ports and jacks that are integral parts of the motherboard. The other ports, sockets and onboard components of the motherboard are:

Onboard components of a motherboard include: sockets, ports and jacks. The other ports, sockets and onboard components of the motherboard are: CPU socket (1) - Provides place for CPU on the motherboard. This socket is a Zero Insertion Force (ZIF) socket. Northbridge (2) - Handles the communication between the CPU, main memory, AGP Port and another very important component known as the south bridge controller. Southbridge (3) - Handles all the operations of devices and buses that are not controlled by the north bridge. DDR DIMM sockets (4) - Provides support for the memory using DDR DIMM. This motherboard has four DDR DIMM sockets. Super I/O controller (5) - Provides the super I/O functionality. Rash ROM (6) - Contains programmable BIOS. Standby Power LED (7) - Indicates if there is standby power on the motherboard. Audio CODEC (8) - Enables audio playback by providing DAC channels. LAN controller (9) - Supports networking functions. Mouse port (10) - Connects the PS/2 mouse. Parallel port (11) - Connects parallel devices like printers. LAN port (12) - Enables connection of LAN through a hub. Line In jack (13) - Connects audio devices like a tape player. Line Out jack (14) - Connects a speaker or a headphone. ,. Microphone jack (15) - Connects a microphone. USB ports (16) - Enables connection to USB devices. Video port (17) - Used to connect to a VGA monitor or another VGA compatible device. Serial port (18) - Connects the mouse or other serial devices. Keyboard port (19) - Connects the PS 2 keyboard. Memory Slots Memory slots provide an interface for attaching RAM on the board. RAM module is inserted in these slots. Most of the motherboards come equipped with at least 2 memory slots. The maximum number of slots available depends on the motherboard. Memory slots are either Single Inline Memory Module (SIMM) or are Double Inline Memory Module (DIMM). All memory slots are labeled accordingly. SIMM's need to be inserted in pairs but DIMM may be inserted individually. CPU Socket CPU socket commonly known as CPU slots is an interface that connects the CPU with motherboard. Sockets are mainly used with a particular type of processor. It consists of holes in which the pins of the processor are installed. Sockets are already installed on the board-Most of the sockets used are built on the Pin Grid Area (PGA) architecture. Processors are placed on to the socket without exerting any pressure. The sockets vary in type and size.
