average time required for the microprocessor to get the data it needs from the main memory by storing recently accessed data in the cache.
CardBus
CardBus technology enables the computer to use
CMOS memory
CMOS (complementary metal oxide semiconductor) memory is powered by the CMOS battery. The System Setup settings and other parameters are maintained in CMOS memory. Even when you turn your computer off, the information in CMOS memory is saved.
COM port
COM stands for communication. COM ports are the serial ports in your computer.
Conventional memory
The first 640 KB of system memory. Operating systems and application programs can directly access this memory without using
Disc
A compact disc (CD).
Disk
The device used by the computer to store and retrieve information. Disk can refer to a floppy disk, hard disk, or RAM disk.
Disk cache
A software device that accumulates copies of recently used disk sectors in RAM. The application program can then read these copies without accessing the disk. This, in turn, speeds up the performance of the application.
