- layered driver
- One of a collection of drivers that responds to the same IRPs. Layered
driver describes the highest-level and lowest-level drivers in a chain of
layered drivers that process the same IRPs, along with all intermediate

- Any feature in the PC system based on older technology for which

- local bus
- Usually refers to a system bus directly connected to the microprocessor on
a system board. Used colloquially to refer to system board buses located
closer to the microprocessor than are ordinary expansion buses (that is, with
less buffering), which are therefore capable of greater throughput.
- lossless compression
- Ensures that the original data is exactly recoverable with no loss in
- lossy compression
- The original data is not completely recoverable. Although image quality
may suffer, many experts believe that up to 95 percent of the data in a
typical image may be discarded without a noticeable loss in apparent
- Least-recently used. Algorithm for paging.
- Used to describe the black-and-white component of a video signal. The
amount of luminance contained in a video signal is directly related to the
amount of light intensity. Also, brightness; one of the three image
characteristics coded in composite television (represented by the letter Y).
