The motherboard is the computer backbone providing electrical connections and allowing communication through all components of the computer. The motherboard houses the central processing unit, or CPU. All electrical devices present on a computer system, including peripheral devices, are routed through the motherboard. The word ?motherboard? usually implies a computer motherboard, but these boards are also present in cell phones, stopwatches, and many other electronic devices. The components of computer motherboards are: 1. a clock generator 2. power connectors 3. input device connectors and expansion slots 4. CPU slots 5. main memory slots 6. Chipset interface 7. non-volatile memory chips
The motherboard has electrical sockets for the microprocessor. There can be more than one microprocessor on the motherboard. The microprocessor is also referred to as a CPU, or central processing unit. The CPU is where execution of computer programs takes place.
Motherboards contain the sockets for the system?s main memory, usually comprised of dual inline memory modules. These are also called DIMM modules. They contain dynamic random access memory chips. These are also known as DRAM chips.
Integrated circuits that interface main memory with peripheral buses are called chipsets and these are present on motherboards as well. These chipsets can be referred to as the Northbridge and Southbridge. The Northbridge being responsible for high speed devices and the Southbridge being responsible for low speed devices. The performance of the computer is related to the speed of the motherboard chipset.
Non-volatile memory chips are present on the motherboard. An example of this type of memory chip is the BIOS, or basic input/output system. This system is responsible for ensuring a computer boots properly by initializing, identifying and testing each of the system devices.
Motherboards contain non-volatile memory chips. The most commonly known type of non-volatile memory is the basic input/output system, or BIOS. The reason the BIOS is so well known, is because it stores settings that control the booting of a computer. When the computer starts up, the BIOS settings routinely initialize, identify and test system devices for functionality.
Motherboards usually contain expansion slots, or sockets. These are areas where computer owners can add expansion cards to increase the functionality of the computer system. These expansion slots can be used for adding things like graphic cards, sound cards or input/output devices.
Motherboards contain components known as power connector flickers. These flickers take power from the main supply and dispense power throughout the computer. These flickers provide power to the CPU, chipsets, main memory, and expansion cards.
Occasionally motherboards quit working properly. Some symptoms of motherboard malfunction include: 1. a computer lock up 2. one long beep and three short beeps 3. change or incorrect time 4. an error message appears on your computer that indicates DMA, CMOS battery or RAM failure 5. the computer power light is working, but the computer will not boot up
