bps – Bits per second. Also often preceded by k (kilo/thousands), kbps – Kilobits per
second, and M (mega/million), Mbps – Megabits per second.
Bps – Bytes per second. (1 Byte is 8 Bits) kbps – kilobytes per second. Mbps –
megabytes per second.
Bus Mastering – A method of transferring data through a bus in which the device takes
over the bus and directly controls the transfer of data to the computer's memory. Bus
mastering is a method of Direct Memory Access (DMA) transfer.
Cache – Cache RAM is an extra holding area for program instructions that need to be
frequently used by the CPU or swapped in and out of RAM. Your CPU can usually
access those instructions from the cache more quickly than it could from a hard disk or
even RAM, so a cache helps the system work more efficiently. Most systems sold
today offer either 256K or 512K cache.
CPU (Central Processing Unit) – executes all commands and controls the flow of data,
providing the " brain " that enables the PC to calculate and perform the operations like
sorting information more quickly than a human could. The CPU makes perhaps the
greatest contribution to a PC's speed and power. Note: Any additional information is
