- Usually used in reference to the amount of data per unit of time that must
move from one point to another, such as from CD-ROM to processor.
- Basic input/output system. A set of routines that works closely with the
hardware to support the transfer of information between elements of the
system, such as memory, disks, and the monitor. Although critical to
performance, the BIOS is usually invisible to the end user; however,
programmers can access it.
- BIOS enumerator
- Responsible in a non-ACPI Plug and Play system for identifying all
hardware devices on the motherboard of the computer. The BIOS supports an API
that allows all Plug and Play computers to be queried in a common manner.
- bit map
- Representation of characters or graphics by individual pixels arranged in
rows (horizontal) and columns (vertical). Each pixel can be represented by
either 1 bit (simple black and white) or up to 32 bits (high-definition
- bit-mapped graphics
- Images created with matrices of pixels or dots. Also raster
- bit specifications
- Number of colors or levels of gray that can be displayed at one time.
Controlled by the amount of memory in the computer's graphics controller card.
An 8-bit controller can display 256 colors or levels of gray; a 16-bit
controller, 64,000 colors; and a 24-bit controller, 16.8 million colors.
- Bits per pixel. The number of bits used to represent the color value of
each pixel in a digitized image.
- Bits per second. The number of bits transferred per second in a data
communications system. A measure of speed.
- The value associated with a pixel, representing its gray value from black
- broadcast architecture
- The set of technologies that enable PCs to receive broadcast data.
- A reserved portion of memory in which data is temporarily held pending an
opportunity to complete its transfer to or from a storage device or another
location in memory.
- bus enumerator
- In a Plug and Play system, a bus device driver that detects devices
located on a specific bus and loads information about devices into the
