What's Inside a Computer?

what's on a motherboard?

NIC

A network interface controller (NIC, also known as a network interface card, network adapter, LAN adapter or physical network interface, and by similar terms) is a computerhardware component that connects acomputer to a computer network.

Audio Jacks

A socket for plugging in an audio source. Audio jacks are found on many types of audio equipment and musical instruments that accept external sound sources.

AGP Slot

(Accelerated Graphics Port) A hardware interface from Intel for connecting a display adapter (graphics card) to a PC. Superseded by PCI Express, a single AGP slot on the motherboard provided a direct connection between the card and memory.

PCI-E Slot

A high-speed hardware interface from Intel for connecting peripheral devices.

COMOS battery

CMOS is short for Metal-Oxide Semiconductor. CMOS is an on-board, battery powered semiconductor chip inside computers that stores information. This information ranges from the system time and date to system hardware settings for your computer. The picture shows an example of the most common CMOS coin cell battery used to power the CMOS memory.

SATA port


    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.

IDE connector

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.
