bps bits per second
bus The pathway used to communicate between the CPU,
memory, and various input/output devices, including
floppy and hard disk drives. Available in various
widths (8-, 16-, and 32-bit), with accompanying
increases in speed.
cache A high-speed memory that resides logically between a
central processing unit (CPU) and the main memory.
This temporary memory holds the data and/or
