algorithm or method used to order elements by comparing 2 sequential elements at a time and swapping them if they are not in order. To start: compare 1 and 2, then 2 and 3, then 3 and 4, etc. to the ed of the list. Repeat this process until one pass through the list involves no swaps.
portion of storage used to hold input or output data temporarily
pathway used for sending signals between the internal components of a computer. Components can share the same bus, but cannot transmit simultaneously.
a network in which all devices are connected to a common cable known as the "bus"
set of bits considered as a unit; it normally consists of 8 bits and corresponds to a single character of information.
wire or glass fibre used to connect computers over a network
part of the main store that is between main memory and the processor. It holds a copy of data ad instructions that are likely to be used next by the processor and is therefore faster than the main memory.
computer-assisted software engineering
finite set of different characters that is complete for a given purpose, for example, the 128 ASCII characters
digit added to numerical data that can be recalculated and hence used to check data integrity after input, tranmission and so on.
