|
A sound system that contains five speakers and a subwoofer.
|
5.1 Sound
|
|
|
An alternate method of providing termination for the quicker fast/wide SCSI that use voltage regulators instead of resistors to terminate devices.
|
Active Termination
|
|
|
The tube of a monitor in which rays of electrons are beamed onto a phosphorescent screen to produce images. Also a shorthand way to describe a monitor that uses CRT rather than LCD technology.
|
Cathode Ray Tube
|
|
|
A method of connecting together several devices along a bus and managing the signals for each device.
|
Daisy Chaining
|
|
|
To remove magnetism from a device. The term is usually used in reference to color monitors and other display devices that use a Cathode Ray Tube (CRT). These devices aim electrons onto the display screen by creating magnetic fields inside the CRT. External magnetic forces-- such as the earths natural magnetism or a magnet placed close to the monitor-- can magnetize the shadow mask, causing distorted images and colors.
|
Degauss
|
|
|
Also known as positional audio, a version of DirectX that offers a range of commands to place sound anywhere in 3D space. The precursor to EAX.
|
DirectSound3D
|
|
|
A series of standards promulgated by Microsoft that enables applications running on Windows platforms to control hardware directly.
|
DirectX
|
|
|
Also called phosphor pitch, a measurement that indicates the diagonal distance between like colored phosphor dots on a display screen. Measured in millimeters, it is one of the principal characteristics that determines the quality of display monitors. The lower the number, the crisper the image.
|
Dot Pitch
|
|
|
A CD media format that provides for 4-17 GB of video or data storage.
|
DVD
|
|
|
3-D sound technology developed by Creative Labs, but now supported by most sound cards.
|
Environmental Audio Extensions (EAX)
|
|
|
Also known as differential SCSI these devices employ two wires per bit of data: one wire for data and one for the inverse of this data. By taking the difference of the two signals, the device can reject common mode noise, allowing for greater distance in the chain.
|
High Voltage Differential
|
|
|
In a CRT, the speed at which the electron beam can draw one line across the screen and be ready for the next lin measured in KHz.
|
Horizontal REfresh Rate
|
|
|
A display technology that relies on poloarized light passing through a liquid medium rather than on electron beams striking a phosphorescent surface.
|
LCD ( Liquid Crystal Display)
|
|
|
Solid state device that vibrates at luminous frequencies when current is applied. In other words, an LED glows like a light when you run electricity through it.
|
LED(Light Emitting Diode)
|
|
|
these enable a SCSI chain to support more than one device per SCSI ID by providing a unique identifier for up to seven sub units per ID number. Primarily used in hard drive arrays.
|
Logical Unit Numbers (LUNS)
|
|
|
A standard that sdescribes the interface between a computer and a device for simulating musical instruments. Rather than sending large sound samples, a computer can simply send "instructions" to the instrument describing pitch, tone, and duration of a sound- these files are therefore very efficient.
|
MIDI
|
|
|
An audio compression scheme used extensively on the internet.
|
MP3 (MPEG-1 Audion Layer 3)
|
|
|
In computer graphics, the smallest element of a display space that can be independently assigned color or intensity.
|
Pixel
|
|
|
An adapter card that plugs into the 40-pin connector of a parallel ATA and allows the drive to be used in SATA system. requires the use of an additional power connector.
|
SATA bridge
|
|
|
A powerful and flexible peripheral interface popularized on the Macintosh and used to connect hard drives, CDROM drives, tape drives, scanners, and other devices to PCs of all kinds. Normal types enables up to seven devices to be connected through a single bus connection, whereas some can handle 15 devices attached to a single controller.
|
SCSI (Small Computer System Interface)
|
|
|
The unique identifier (from 0-15) on a SCSI chain used to differentiate the devices for the SCSI controller car.
|
SCSI ID
|
|
|
A serial link a single cable wiht t minnumum of four wires creates a point ot point connection between devices. Transfer rates begin at 150MBps. One of the main dsign advantages is that the thinner serial cables facilitate more efficient airflow inside a form factor and also allow for smaller chassis designs.
|
Seral ATA (SATA)
|
|
|
An evolutino of parallel SCSI into a point to point serial peripheral interface in which controllers are linked directly to disk drives. it is a performance imporvement over traditional SCSI because it enables multiple devices (up to 128) of different sizes and ty0es to be connected simultaneously wiht thinner and longer cables; its full duplex signal transmission supports 3.0Gb/s.
|
Serial Attached SCSI
|
|
|
A type of LCD flat panel display screen, in which each pixel is controlled by from one to four transistors. This technology provides the best resolution of all the flat panel techniques, but it is also the most expensive. Sometimes called active matrix LCDs.
|
Thin Film Transistor (TFT)
|
|
|
The number of times per second the electron guns in a CRT can draw then entire screen and then return to the upper left hand corner. Measured in Hz (screens per second)
|
Vertical Refresh Rate
|
