what 's inside a computer?
what's in a motherboard?
CPU (pronounced as separate letters) is the abbreviation forcentral processing unit.
Sometimes referred to simply as the central processor, but more commonly called processor, the CPU is the brains of the computerwhere most calculations take place. In terms of computing power, the CPU is the most important element of a computer system.
CPU fan cooler
A device that draws heat away from a CPUchip and other hot-running chips such as a graphics processor (GPU). See heat pipe and notebook cooler. Heat Sink. The simplestcooler is an aluminum heat sink, which absorbs and disperses the heat. Fans and Heat Sinks Together.
Random-access memory (RAM /ræm/) is a form of computer data storage. A random-access memory device allows data items to be accessed (read or written) in almost the same amount of time irrespective of the physical location of data inside the memory.
Northbridge is an Intel chipset that communicates with the computer processor and controls interaction with memory, the Peripheral Component Interconnect (PCI) bus, Level 2 cache, and all Accelerated Graphics Port (AGP) activities.
Southbridge is a reference to a chipset on a PC motherboard. It is a group of microchips designed for a single function and manufactured as a single unit. This chipset controls or manages input and output (I/O). Examples of I/O interface connections controlled by southbridge are USB, serial, IDE and ISA.
A Video Graphics Array (VGA) connector is a three-row 15-pin DE-15 connector. The 15-pinVGA connector is found on many video cards, computer monitors, and high definition television sets. On laptop computers or other small devices, a mini-VGA port is sometimes used in place of the full-sized VGA connector.
Analog ground. Return for R, G, and B signals.Digital Visual Interface (DVI) is a video display interface developed by the Digital Display Working Group (DDWG). The digital interface is used to connect a video source, such as a display controller to a display device, such as a computer monitor.
Definition of:USB (1) Short for "USB flash drive" or "USB port." See USB drive andUSB port. (2) (Universal Serial Bus) The most widely used hardware interface for attaching peripherals to a computer.
A network interface card (NIC) is a circuit board or card that is installed in a computer so that it can be connected to a network.
A socket for plugging in an audiosource. Audio jacks are found on many types of audio equipment and musical instruments that accept external sound sources.
The Accelerated Graphics Port (often shortened toAGP) is a high-speed point-to-point channel for attaching a video card to a computer system, primarily to assist in the acceleration of 3D computer graphics. It was originally designed as a successor to PCI-type connections for video cards.
PCI is the initialism for Peripheral Component Interconnect and is part of the PCI Local Bus standard. The PCI bus supports the functions found on a processor bus but in a standardized format that is independent of any particular processor's native bus.
PCI Express (Peripheral Component Interconnect Express), officially abbreviated as PCIe, is a high-speed serial computer expansion bus standard designed to replace the older PCI, PCI-X, and AGP bus standards.
CMOS battery - Computer Definition. A battery that maintains the time, date, hard disk and other configuration settings in the CMOSmemory. CMOS batteries are small and are attached directly to the motherboard. See BIOS setup and batteries.
SATA is the faster serial version of the parallel ATA (PATA) interface. Both SATA and PATA are "integrated drive electronics" (IDE) devices, which means the controller is in the drive, and only a simple circuit is required on the motherboard.
Integrated Drive Electronics (IDE) is a standard interface for connecting a motherboard to storage devices such as hard drives and CD-ROM/DVD drives. The original IDE had a 16-bit interface that connected two devices to a single-ribbon cable.
