bus - The internal pathway for signals moving around inside a computer, transferring data between various components. In practice the bus is a collection of very fine wires or metal etchings on the system board which also appears as the connector for plug-in boards and other devices. So the bus type decides what extras you can slot in. Buses for PCs come in three main flavours: ISA (outdated now), VESA (more modern, permits faster movement of data, but now effectively supplanted) and PCI (top dog at the moment. Any computer which does not have this type should be avoided).
BVM - Beata Virgo Maria Blessed Virgin Mary
Byte - The collection of bits that make up a binary word; eight bits, and used to reprent a single character. Eight bits (binary digits - 0 or 1, on or off, yes or no) form one byte, and different patterns of eight bits give you enough combinations to represent most of the standard alphanumeric and punctuation characters. A kilobyte is 1,024 bytes (and not 1,000 bytes), which makes a megabyte 1,048,576 bytes.
