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 32-bit PC
Cards. Hardware in the computer and the Windows 95
operating system provide support for the 32-bit cards. The
voltage of 32-bit cards (3.3 volts) is lower than that of 16-bit
cards (5 volts). The 32-bit cards can transmit more data at a
time than the 16-bit cards, thus increasing their speed.
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 memory-management software.
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.
