Parts Of Motherboard

Motherboard - A motherboard is the underlying circuit board of a computer. The central processing unit (CPU), Random Access Memory (RAM), hard drive(s), disk drives and optical drives are all plugged into interfaces on the motherboard. A video interface and sound card can be optionally built-in or added.

PARTS OF THE MOTHERBOARD

Processor - A silicon chip that contains a CPU. In the world of personal computers, the terms microprocessor and CPU are used interchangeably. At the heart of all personal computers and most workstations sits a microprocessor. Processor socket - is an electrical component that attaches to a printed circuit board (PCB) and is designed to house a CPU (also called a microprocessor). It is a special type of integrated circuit socket designed for very high pin counts. A CPU socket provides many functions, including providing a physical structure to support the CPU, providing support for a heat sink, facilitating replacement (as well as reducing cost) and most importantly forming an electrical interface both with the CPU and the PCB. CPU sockets can most often be found in most desktop and server computers, particularly those based on the Intel x86 architecture on the motherboard.

Heat sink - is an environment or object that absorbs and dissipates heat from another object using thermal contact (either direct or radiant). Heat sinks are used in a wide range of applications wherever efficient heat dissipation is required; major examples include refrigeration, heat engines, cooling electronic devices and lasers.

PC memory slot - Commonly refers to the slot computer memory is placed into on the computer motherboard I/O Board. Term can also be used to describe PC card capable of storing data on the card.

Power Connector - is an electrical connector designed to carry a significant amount of electrical power, usually as DC or low-frequency AC. Some types of RF

connector may also carry large amounts of power, but are considered as a separate category. Connectors carrying small amounts of power are known as signal connectors.

Sound card - is a device that handles datato-audio and audio-to-data translations, enabling a computer to play sound on speakers or to record sound from an external device, like a microphone. BIOS - The initial function of the BIOS is to identify, test, and initialize system devices such as the video display card, hard disk, and floppy disk and other hardware. This is to prepare the machine into a known state, so that software stored on compatible media can be loaded, executed, and given control of the PC.

IDE, ATA And S-ATA Interface Connectors - Many interface standards have been created throughout the years, maybe too many for discussing about all of them. I will then talk about the ATA and the S-ATA only as the IDE is the same thing as the ATA, only the name has changed. Also I will be brief because it is more a hard drive topic than anything else. The Advance Technology Attachment (ATA) interface is used to connect hard drives and optic drives. You can attach 2 drives on the same ribbon, 1 master and the other slave, and it supports almost all modern hard drives storage capacities. Modern computer mother boards have the new interface called Serial Advance Technology Attachment (S-ATA). It is faster than the ATA and only 1 device can be attached to it. The wire is thinner than his predecessor and surely help at the cooling process inside the computer case. Floppy Drive Connector - The floppy disk interface uses what is likely the strangest cable of all those in PCs today. It is similar to the standard IDE cable in that it is usually a flat, gray ribbon cable. It is unusual in terms of the number of connectors it has and how it is used to configure the setup of the floppy disks in the system. Capacitors - An electronic component that stores an electric charge and releases it when required. It comes in a huge variety of sizes and types for use in regulating power as was for conditioning, smoothing and isolating signals. Capacitors are made from many different materials, and virtually every electrical and electronic system uses them.

devices in a computer. These devices can take either the form of an integrated circuit fitted onto the motherboard itself, called a planar device in the PCI specification or an expansion card that fits into a slot. AGP (Accelerated Graphics Port) - is a highspeed point-to-point channel for attaching a video card to a computer's motherboard, primarily to assist in the acceleration of 3D computer graphics. BACK PANNEL CONNECTOR Parallel Port - is a type of interface found on computers for connecting various peripherals. It is also known as a printer port or Centronics port. The parallel interface was adapted to access a number of peripheral devices other than printers. Serial Port - is a serial communication physical interface through which information transfers in or out one bit at a time (contrast parallel port). Throughout most of the history of personal computers, data transfer through serial ports connected the computer to devices such as terminals and various peripherals.

PS/2 connector - is used for connecting some keyboards and mice to a PC compatible computer system. Its name comes from the IBM Personal System/2 series of personal computers, with which it was introduced in 1987.

PCI (Peripheral Component Interconnect) is a computer bus for attaching hardware

BACK PANNEL CONNECTORS

Network Adapter - interfaces a computer to a network. The term "adapter" was popularized originally by Ethernet add-in cards for PCs.

USB Ports - These USB connectors let you attach everything from mice to printers to your computer quickly and easily.

Audio ports and video port - are electrical connectors for carrying an audio signal or video signal, either in an analog or digital format. Analog A/V connectors often use Shielded cable to inhibit RF interference and noise. Microphone Connector – used for connecting the microphone to the computer.
