Computer Dictionary


BIOS
BIOS stands for Basic Input/Output System. It is a permanent part of your computer and stored in special Read-Only Memory chips. Consequently, the BIOS used to be called the ROM BIOS. It is a set of instructions that tell the microprocessor in your computer what to do.
 
Dual Core CPU
A dual-core CPU combines two independent processors and their respective caches and cache controllers onto a single silicon chip, or integrated circuit.
 
HDA (High Definition Audio)
High Definition Audio, also known as HD Audio or by its codename, Azalia, is a standard for high-quality on-board audio. This standard provides two new features: multi-streaming, which allows more than one audio signal to be sent to a different audio device and high quality audio.
 
HDCP (High-Bandwidth Digital Content Protection)
HDCP stands for High-Bandwidth Digital Content Protection, a copy protection scheme to eliminate the possibility of intercepting digital data midstream between the source to the display. The format designed by Intel and licensed by Digital Content Protection, LLC using an authentication and key exchange procedure before video and audio is presented. Products compatible with the HDCP scheme such as DVD players, satellite and cable HDTV set-top-boxes, as well as few entertainment PCs requires a secure connection to a compliant display, the process often described as the handshake.
 
HDTV (High Definition TV)
A television system that has twice the standard number of scanning lines per frame and therefore produces pictures with greater detail.
 
HDV Link
HDV is a SiS proprietary high-bandwidth video interface between SiS IGU chip and SiS Video Bridge chip and it is applied for the series of SiS HDV-compliant IGU and Video Bridge chips.
 
IEEE 1394
The IEEE 1394 multimedia connection enables simple, low-cost, high-bandwidth isochronous (real-time) data interfacing between computers, peripherals, and consumer electronics products such as camcorders, VCRs, printers, PCs, TVs, and digital cameras.
 
PATA (Parallel ATA)
Parallel ATA is the primary internal storage interconnect for the desktop, connecting the host system to peripherals such as hard drives, optical drives, and removable magnetic media devices.
 
PCI Express
PCI Express is a new interconnect technology designed to provide universal connectivity for use as a chip-to-chip and chip to adapter card interconnect. PCI Express will be the I/O architecture for everything from graphics adapters to Ethernet cards to TV tuners. This massive bandwidth will alleviate many current and future performance bottlenecks on the adapter bus. PCI Express is based on a type of serial communications technology somewhat like that in USB or SATA hard drives. The mechanical (physical) board connectors come in one of four types: x1, x2, x4, and x16 (see illustration below) in order to meet different peak bandwidth requirements.
 
SATA (Serial ATA)
Serial ATA is a computer bus technology primarily designed for transfer of data to and from a hard disk. It is the successor to the legacy AT Attachment standard (ATA). SATA is the next-generation internal storage interconnect, designed to replace parallel ATA technology. SATA is the proactive evolution of the ATA interface from a parallel bus to a serial bus architecture. This architecture overcomes the electrical constraints that are increasing the difficulty of continued speed enhancements for the classic parallel ATA bus.
 
TPM(Trusted Platform Module)
Trusted Platform Module (TPM) is both the name of a published specification detailing a microcontroller that can store secured information, as well as the general name of implementations of that specification. The TPM provides the ability for a PC desktop or notebook to run applications more securely and to perform electronic transactions and communication more safely.
 
Video Bridge
To extend the display capability of the system with SiS HDV-compliant IGU chipset and provides one digital DVI panel and one analog TV-out display extension.
 
WLAN (Wireless LAN)
Wireless LAN (or WLAN, for wireless local area network, sometimes referred to as LAWN, for local area wireless network) is one in which a mobile user can connect to a local area network (LAN) through a wireless (radio) connection.
