(n.) A small device or circuit that regulates the voltage fed to the microprocessor. The power supply of most PCs generates power at 5 volts but most microprocessors require a voltage below 3.5 volts. The voltage regulator’s job is to reduce the 5 volt signal to the lower voltage required by the microprocessor. Typically, voltage regulators are surrounded by heat sinks because they generate significant heat.
Pentium microprocessors with MMX actually require two voltage regulators — one for the internal (core) voltage, and one for the I/O drivers at 3.3 volts.
Some voltage regulators, particularly those packaged as a voltage regulator module (VRM), are voltage ID (VID) programmable, which means that the microprocessor can program the voltage regulator to provide the correct voltage during power-up.
A fixed amount of storage on a disk or tape. The term volume is often used as a synonym for the storage medium itself, but it is possible for a single disk to contain more than one volume or for a volume to span more than one disk.
- volume label
In DOS systems, the name of a volume (that is, the name of a disk or tape). Specifying a volume label makes it easier to keep track of what data is stored on each medium.
(1) Capitalized, VOX is short for voice operated switch it is a term commonly used in telecommunications. It refers to a switch that works when a sound is detected by a device (transmitter or recording device) which is activated by the sound in place of a user a pushing a button to transmit. (2) In […]
Short for volume pixel, the smallest distinguishable box-shaped part of a three-dimensional image. Voxelization is the process of adding depth to an image using a set of cross-sectional images known as a volumetric dataset. These cross-sectional images (or slices) are made up of pixels. The space between any two pixels in one slice is referred […]
Introduced by DEC in August 1978, Video Terminal 100 was the first terminal to use a general-purpose processor for interpreting the newly published (1977) ANSI control codes (ANSI X3.64). Quickly, the vt100 become popular, and the ANSI control codes embodied in the vt100 became a de facto standard. Eventually, IBM adopted them for its line […]
