CPU Socket. CMOS Battery. Power Connectors. The central processing unit CPU , also called a processor, is located inside the computer case on the motherboard. It is sometimes called the brain of the computer, and its job is to carry out commands. Whenever you press a key, click the mouse, or start an application, you're sending instructions to the CPU. It's called a motherboard because it is the main circuit board in the computer, and it can be extended by plugging other circuit boards into it.
These extensions are called daughter boards. The central processing unit CPU of a computer is a piece of hardware that carries out the instructions of a computer program. A motherboard , also known as the "main board," is the central circuit hub that allows connection between all components and peripherals attached to the computer. It also allows all the components such as CPU, graphics card, hard drive and the memory to receive power from the attached power supply.
A motherboard is composed of layers that have copper embedded in between fiberglass. If you were to drill through one of the copper lanes, it would be the end of your motherboard. Officially, the recommended customer price of one boxed Intel Core iK processor four cores with Hyper-Threading, 4.
Your data is stored on your hard drives. Erasing your hard drives, damaging your hard drives, reinstalling your operating systems on top of your data … THOSE things would likely cause you to lose your data. Motherboards In , the best motherboard model had a failure rate of 1. Module 2: Computer Hardware. Search for:. Reading: Motherboard Motherboard for an Acer desktop personal computer, showing the typical components and interfaces that are found on a motherboard.
A motherboard sometimes alternatively known as the mainboard , system board , planar board or logic board , or colloquially, a mobo is the main printed circuit board PCB found in computers and other expandable systems. It holds and allows communication between many of the crucial electronic components of a system, such as the central processing unit CPU and memory, and provides connectors for otherperipherals.
Unlike a backplane, a motherboard contains significant sub-systems such as the processor and other components. With the steadily declining costs and size of integrated circuits, it is now possible to include support for many peripherals on the motherboard. By combining many functions on one PCB, the physical size and total cost of the system may be reduced; highly integrated motherboards are thus especially popular in small form factor and budget computers.
A motherboard of a Vaio E series laptop. Motherboards are generally air cooled with heat sinks often mounted on larger chips, such as the Northbridge, in modern motherboards. Insufficient or improper cooling can cause damage to the internal components of the computer, or cause it to crash. Most motherboards have connectors for additional case fans and integrated temperature sensors to detect motherboard and CPU temperatures and controllable fan connectors which the BIOS or operating system can use to regulate fan speed.
Alternatively computers can use a water cooling system instead of many fans. Licenses and Attributions. CC licensed content, Shared previously. If you decide to open the computer case and take a look, make sure to unplug the computer first. Before touching the inside of the computer, you should touch a grounded metal object —or a metal part of the computer casing —to discharge any static buildup. Static electricity can be transmitted through the computer circuits, which can seriously damage your machine.
Most computers have expansion slots on the motherboard that allow you to add various types of expansion cards. These are sometimes called PCI peripheral component interconnect cards. You may never need to add any PCI cards because most motherboards have built-in video, sound, network, and other capabilities. However, if you want to boost the performance of your computer or update the capabilities of an older computer, you can always add one or more cards.
Below are some of the most common types of expansion cards. The video card is responsible for what you see on the monitor. Most computers have a GPU graphics processing unit built into the motherboard instead of having a separate video card. If you like playing graphics-intensive games, you can add a faster video card to one of the expansion slots to get better performance.
The sound card —also called an audio card —is responsible for what you hear in the speakers or headphones. Most motherboards have integrated sound, but you can upgrade to a dedicated sound card for higher-quality sound. Yes, although the board is often referred to as a "logic board" and not a motherboard. The logic board is very similar to a motherboard and operates the same way. However, because of size requirements with most logic boards, components like the processor and RAM in tablets and smartphones are soldered onto the board.
Also, because many of these devices have no upgrade options, there are no slots or sockets like a traditional computer motherboard. Home Dictionary M - Definitions. Motherboard overview.
