What is the function of the motherboard on the computer?
A motherboard is also known as a main board, system board and logic board. A common abbreviation is 'mobo'. They can be found in a variety of electrical devices, ranging from a TV to a computer. Generally, they will be referred to as a motherboard or a main board when associated with a complex device such as a computer, which is what we shall look at. Put simply, it is the central circuit board of your computer. All other components and peripherals plug into it, and the job of the motherboard is to relay information between them all. Despite the fact that a better motherboard will not add to the speed of your PC, it is none-the-less important to have one that is both stable and reliable, as its role is vital.
A motherboard houses the BIOS (Basic Input/Output System), which is the simple software run by a computer when initially turned on. Other components attach directly to it, such as the memory, CPU (Central Processing Unit), graphics card, sound card, hard-drive, disk drives, along with various external ports and peripherals.

Why is the motherboard called the heart of the computer?
The reason the motherboard is refereed to as the heart is because much like the heart in our body, it allows everything to function, a sort of gateway in which everything must run through to have life
Functions of the motherboard parts?
1 - Firewire header Firewire is also known as IEEE 1394. It is basically a high performance serial bus for digital and audio equipment to exchange data. The technology preceded USB but yet is faster than any current USB port. Often used for transferring digital video to the PC straight from a digital camera. The FireWire header onboard means you can install a FireWire port on your machine. Again these cables are often supplied as an optional extra which you will need to check with the retailer to see if they are supplied with your board. 2 - PCI Express 16x slots Now the most common slot for Graphics cards, the PCI Express 16x slots provides 16 separate lanes or data transfer. PCI express 1.0 slots offer a data transfer rate of 250MB/s the second generation of PCI express (PCI Express 2.0) offers twice the data rate at 500MB/s. Currently in development is PCI Express 3.0 which offers 1GB/s of data transfer. PCI Express 16x slots are also the basis for both SLI and Crossfire multi graphics card setups. With the increasing demands graphics cards are putting on systems, no less than a 16 lane slot will be good enough for any modern graphics card. 3 - PCI Express 1x Slot Like the PCI Express 16x above the 1x slot uses exactly the same system but only has a single lane of serial data transfer. These slots are used for expansion cards that do no require the same amount of data transfer that a graphics card requires. You will usually find components such as tv tuners, network cards and sound cards make use of the PCI Express 1x slot. You will also notice the difference in size between the 1x and the 16x slots. The PCI Express 1x slot is noticeably smaller and easy to spot. 4 - Chipset - North Bridge (with heatsink) The Motherboards chipset can be described as what sets it apart from other boards in its category. Different chipsets contain different features and components. A chipset is a number of integrated circuits built onto the board to provide specific functions e.g. one part of the chipset may be an onboard component such as a modem or sound chip. Other parts may be used to control the CPU functions. Most chipsets are designed to work with only one "class" of CPU although now many older chipsets support more than one type of CPU such as socket 7 which supports the Pentium, Cyrix 686, Cyrix MII, AMD K6 and K6-2. There are certain restrictions though to what type of processor a chipset can handle because of the logic that the CPU uses to access the memory and its cache etc. Since these chips are working harder with each generation, motherboard manufacturers have started to put heatsinks and active coolers (fans) on the main parts of the chipset to disperse some of the heat. 5 and 8 - ATX Power connector The standard ATX power connector, the cable for this will be coming from the PSU, a clip is normally provided to make sure you get them in the correct order. As a tip, don't try to push too hard if its stuck, check to see that it is in the correct way, I have seen plenty of power connectors where the pins have pushed out some of the connectors, these can be difficult to get back into place, so its best to be careful. 6 - CPU (Central Processing Unit) socket All the CPU "sockets look very similar, however they are different in the way they have different amount of pins and in different layouts. There are currently two major CPU socket types PGA and LGA. PGA or Pin Grad Array uses a system of pins on the CPU and holes on the socket to line up and hold a CPU in place. The introduction of the ZIF (Zero Insertion Force) socket for PGA types allowed the CPU's to be lined up without any pressure on the CPU until a level is pulled down. LGA or Land Grid Array uses a system of gold plated copper pads that make contact with the motherboard. It is very important to read your motherboard manual to discover what types of CPU's you motherboard supports as most motherboards are aimed at a specific type of CPU. 7 - DIMM (Double Inline Memory Module) slots DIMM's are by far and away the most used memory types in today's computers. They vary in speeds and standards however and they need to match up to what your motherboard has been designed to take. The four standards of DIMM's being used at the moment are SDR (Single Data Rate), DDR (Double Data Rate), DDR2 and DDR3. The speeds of memory can vary between 66Mhz to 1600Mhz. Get great Value on Memory Upgrades at SavaStore Click Here 9 - Motherboard controls Not available on all motherboards, but some allow direct control of the motherboard via simple buttons. Power switch, error checking, CMOS clearing, passwords and more features can be accessed directly on the motherboard on some models. 10 - Chipset - South Bridge When we talk about chipsets you mainly only ever hear about the North bridge. Even those into PC technology have a hard time naming the south bridges without looking them up. Names like Nforce 2 and KT600 are North bridges. The South Bridge does an important job as well. It handles things like the PCI bus, onboard Network and sound chips as well as the IDE and S-ATA buses. 11 - Serial ATA Connector Serial ATA or more commonly seen as S-ATA is a new way of connecting your Hard Drives to your PC. S-ATA drives have the capability of being faster than the IDE counterparts and also have smaller thinner cables which help with the airflow of the system. S-ATA hard disks are fast becoming the norm for hard drive technology. Current motherboards feature both IDE and S-ATA connectors to facilitate all types of storage hardware. 12 - USB 2.0 header As well as having USB ports on the rear of the motherboard, motherboard manufacturers often add a couple of USB headers so you can connect optional cables for extra USB ports. These cables are often supplied and you only need to add them on if you need the extra connectivity. USB 2.0 replaced USB 1.1 as a much faster solution. It is backwards compatible meaning all USB 1.1 devices will work in these new USB 2.0 ports. 13 - Motherboard Battery The battery gives the board a small amount of power in order to store some vital data on your machine when the power is off. Data stored is that like the time and date so you don't have to reset them every time you boot the machine up. Motherboard batteries are usually long lasting Lithium batteries. Removing this can reset all the data on your machine including the BIOS settings, however not replacing this correctly can lead to irreparable damage to the motherboard. Only remove the battery if it is dead or if you can't have access any other way to resetting the data on your machine by use of the clear CMOS jumper or something similar. 14 - PCI (Peripheral Component Interconnect) slot The PCI bus (not PCI express) is now an older technology and although the PCI slots are still available, they have decreased in number and are being replaced by the PCI Express 1x slots. Its unlikely that you will get a motherboard without a PCI slot at the moment due to the fact that a lot of components still use the standard PCI slot. It would be awkward to upgrade to a system without PCI slots as it may mean upgrading more components than you would like to, 15 - Floppy Drive Connector More simple than the IDE connector you only have to remember to get the red line to pin 1 of the connector and the red line to pin 1 on the floppy drive, This port is only to be used with floppy drives. You may not have a floppy controller on your motherboard as its slowly being phased out as more people are using writable CD's and DVDs to transfer data, to store data and to use as boot up discs. 16 - IDE connector Not on Diagram The connector to which you will insert an IDE cable (supplied with motherboard) IDE cables connect devices such as hard disks, CD Drives and DVD Drives. The current 4 standards of IDE devices are ATA 33/66/100 and 133. the numbers specify the amount of data in Mb/s in a max burst situation. In reality there is not much chance of getting a sustain data rate of this magnitude. Both the connectors and devices are backwards compatible with each other, however they will only run at the slowest rated speed between them. All IDE cables will come with a red line down one side, this red line is to show which way it should be plugged in. The red line should always connect to pin one of the IDE port. Checking your motherboard documentation should show you which end is pin one. In some cases it will be written on the board itself. In the case of ATA 66/100/133 there is a certain order that you plug devices in, the cable is colour coded to help you get them in the correct order. . The Blue connector should be connected to the system board . The Black connector should be connected to the master device . The Grey Connector should be connected to the slave device 17 - BIOS (Basic Input Output System) Chip - Not on Diagram The BIOS holds the most important data for your machine, if configured incorrectly it could cause your computer not to boot correctly or not at all. The BIOS also informs the PC what the motherboard supports in terms off CPU etc. This is why when a new CPU is introduced that physically fits into a slot or socket you may need a BIOS update to support it. The main reason for this is that different CPU's use different logics and methods and so the BIOS has to understand certain instructions from the CPU to recognise it.
What is the function of motherboard south bridge?
Is a chip that implements the "slower" capabilities of the motherboard in a northbridge/southbridge chipset computer architecture.
Where is motherboard in a computer?
It is mounted on either the side or bottom of the case. ^It is mounted to a backplane, a metal "plate" that the motherboard screws/clips onto. In most standard cases, the backplane is located on the right side of the case when looking at the front of the case. There are almost no exceptions to this rule, except some small form factor designs where the motherboard sits on the bottom of the case. By far the most common is to mount on the right side though.
What is a motherboard on a computer?
Motherboard is the main structure to which all other devices like CD rom, USB, Soundcard, etc... are connected. All connections are from mother board because the processor and builtin primary harddrive are fixed in mother board.
What is the function of motherboard to computer system?
The motherboard is where most of the processing takes place. The central Processor chip is nearly always on the motherboard. So too is the memory and supporting circuitry. ROM chips and connectors for the controlling switches are found here. The motherboard usually has slots, or connectors for daughter boards, for additional i/o devices and other add ons (so the daughter boards work for the mother!). Devices which are made to be easily upgraded (swappable) can be put onto its own sub-board in an expansion slot. For example, video boards can be substantially speedier and more functional than another one, and it is convenient to be able to switch one without requiring swapping the entire motherboard (if the video was built into it). PCI is one type of connection to a daughter board. Other interfaces, like networking or sound or another processor, can be found on a daughter board. In summary, the motherboard contains some critical components of the system, with connections to other devices to complete the system.

What is the function of the jumper on the motherboard?
Jumpers can do a lot of things, some motherboards have many of them. Basically they are a manual switches, that can be closed by shorting them with a jumper cap. Some examples are, jumpers that set the CPU speed, or reset the BIOS memory.
How is a motherboard and essential part of a computer?
The motherboard is the primary circuit board within a personal computer. Many other components connect directly or indirectly to the motherboard. For example, the CPU (the "brains" of a computer) is connected to the motherboard. It is the main part of a computer The mother board is the central framework of the computer. It is the means by which all communications from one device in the computer are transferred to another device in the computer. It contains a pathway from each device to the CPU (or central processing unit) and back out to the devices again, one of those devices being the monitor for you to interact with.
What is the function of a chipset in a motherboard?
The actual function of a chipset is to communicate between all components of the modern PC, or, to put it in other words, the chipset is the infrastructure. The chipset contains numerous components, and moreover, it makes various interfaces available for connecting additional components (PCI, USB, AGP, IDE, etc). As a rule, the chipset consists of two units, the Northbridge and the Southbridge. The reason that it is made of two units instead of one is that it's difficult to integrate all components onto a single chip. The use of two chips also allows for different combinations of Southbridge and Northbridge chips. Today, most manufacturers have a small building-block type of system from which the motherboard makers can choose components to suit customer requirements. The Northbridge usually contains the CPU interface and the memory controller. With nForce and nForce2, the graphics unit is also on the Northbridge. This chip is clearly larger in size compared to the Southbridge, because hundreds of data paths are needed for the processor and the RAM. Because of this, all complex chips are packed in BGA (Ball Grid Arrays) casing, where all the soldered connections are located on the underside of the chip. The Southbridge contains at least a PCI controller, floppy/ IDE/ hard disk controllers, serial and parallel ports, USB support and power management functions. Through the years, the chipsets have gained extended functionality through the Southbridge, which is the reason that nowadays these units often also include interfaces and codecs for sound or network controllers. This means that motherboard manufacturers only need to provide simple controllers, which are much cheaper to produce than complete PCI network cards or sound cards.

What is the purpose of a motherboard in a computer?
The motherboard is the main printed circuit board and contains the buses, or electrical pathways, found in a computer. These buses allow data to travel between the various components that comprise a computer. A motherboard is also known as the system board, the backplane, or the main board. The motherboard accommodates the central processing unit (CPU), RAM, expansion slots, heat sink/fan assembly, BIOS chip, chip set, and the embedded wires that interconnect the motherboard components. Sockets, internal and external connectors, and various ports are also placed on the motherboard. The form factor of motherboards pertains to the size and shape of the board. It also describes the physical layout of the different components and devices on the motherboard. Various form factors exist for motherboards. An important set of components on the motherboard is the chip set. The chip set is composed of various integrated circuits attached to the motherboard that control how system hardware interacts with the CPU and motherboard. The CPU is installed into a slot or socket on the motherboard. The socket on the motherboard determines the type of CPU that can be installed. The chip set of a motherboard allows the CPU to communicate and interact with the other components of the computer, and to exchange data with system memory, or RAM, hard disk drives, video cards, and other output devices. The chip set establishes how much memory can be added to a motherboard. The chip set also determines the type of connectors on the motherboard. Most chip sets are divided into two distinct components, Northbridge and Southbridge. What each component does varies from manufacturer to manufacturer, but in general the Northbridge controls access to the RAM, video card, and the speeds at which the CPU can communicate with them. The video card is sometimes integrated into the Northbridge. The Southbridge, in most cases, allows the CPU to communicate with the hard drives, sound card, USB ports, and other I/O ports.
How do you remove the motherboard on a computer?
Step 1: Open the case and discharge any static by touching something metal. Step 2: Disconnect all the wires in the case to get the m out of the way. Be sure you know how to get them all back in the right way. Step 3: Remove all the expansion cards such as video cards, sound cards, and network cards. Step 4: If your power supply is top mounted, it probably blocks the motherboard. If it does, remove it. Most bottom mounted PSUs don't cover the motherboard. Step 5: Turn your case on its side so the motherboard is on the bottom. Step 6: Take the heatsink off the CPU. Remove the CPU. Step 7: Take out the RAM cards. Step 8: There should be a number of screws holding the motherboard in. Unscrew them. Step 9: GENTLY lift the motherboard out BY THE EDGES, not the back or front. Note that everything in your computer connects to the motherboard, so if you replace it be sure that everything is compatible.

Is motherboard consider the brains of a computer?
No, the CPU is the brains of the computer and interprets instructions received, equivaqlent to your brain responding to stimuli and selecting a course of action to follow. An equivalent analogy for the motherboard would be your neurological system. The motherboard, like neurotransmitters, receives and transmits messages to and from input/output sources (keyboard, mouse, etc.) to the CPU.
Does every computer have a motherboard?
yes; the motherboard is the board and chips that connect your CPU (the main chip, that does all the computations) to everything else, such as the display, the mouse, the keyboard, and the hard drive.
When you turn on the computer what happens to the motherboard?
The ATX power supply standard requires that there be two supplies in the Power Supply Unit. One is the high power unit to power the PC itself and the other is a low power, low voltage one to bootstrap the PSU into life. The bootstrap power supply is always on. This bootstrap voltage is connected to the power switch via a wire on the ATX PSU conenctor on the motherboard. When you close the switch, it brings the main supply to life and the CPU boots up. Part of the bootup process is to set a bit in a register that electronically "pushes" the button for you, thus keeping the PC powered up. This, by the way, is how a PC can shut down under program control. The CPU just "lets go" of that virtual button, which consists of another one of the wires in the ATX PSU connector. Once powered up and all voltages are stable (typically less than 1 second), the CPU runs the boot up program in the motherboards Flash/ROM memory. This in turn instructs the CPU how to read the Hard Disc Drive to get another boot up program specific to your system. This is usually also the boot up program for your OS, if you are not "dual booting". That program in turn loads your OS into memory and your PC is up and running.
Can computer run without a motherboard?
No. The mother board is required because all data and electricity from all and too all components flow through the mother board.
