The main circuit board of a microcomputer. The motherboard contains the connectors for attaching additional boards. Typically, the motherboard contains the CPU, BIOS, memory, mass storage interfaces, serial and parallel ports, expansion slots, and all the controllers required to control standard peripheral devices, such as the display screen, keyboard, and disk drive. Collectively, all these chips that reside on the motherboard are known as the motherboard’s chipset.
On most PCs, it is possible to add memory chips directly to the motherboard. You may also be able to upgrade to a faster PC by replacing the CPU chip. To add additional core features, you may need to replace the motherboard entirely.
Motherboard is sometimes abbreviated as mobo.

(1) Any type of metal or plastic plate designed to fit over a device or computer component to enhance the device’s functionality or its looks. Cellphones, iPods and even handheld game devices are types consumer electronics that consumers can purchase faceplates for. These faceplates, usually snap on plates, can change the way the device looks, […]
A set of user interface guidelines created by the Open Software Foundation (www.opengroup.org) that specify how an application should look and feel, covering issues like the placement of title bars and menus. It is used on more than 200 hardware and software platforms and has become the standard graphical user interface (GUI ) for UNIX.
JPEG stands for the Joint Photographic Experts Group standard, a standard for storing and compressing digital images. Motion-JPEG extends this standard by supporting videos. In motion-JPEG, each frame in the video is stored with the JPEG format.
- motion compensation and prediction
In video editing motion compensation provides a prediction for the macroblock. When prediction is applied, the DCT is applied to conform to the prediction errors instead of to image samples. Good motion compensation prediction will result in a lower bit rate and still maintain decent quality. Also called motion compensated prediction.
- motion detection
In video surveillance, motion detection refers to the capability of the surveillance system to detect motion and capture the events. Motion detection is usually a software-based monitoring algorithm which, when it detects motions will signal the surveillance camera to begin capturing the event. Also called activity detection. An advanced motion detection surveillance system can analyze […]
