- 1SIMPLEXdata travels in one direction only.
- 2HALF DUPLEXdata travels in both directions, but not simultaneously.
- 3FULL DUPLEXdata travels in both directions simultaneously.
- 4BIT RATEthe number of bits per second that can be transmitted along a digital network.
- 5BAUDa unit of transmission speed equal to the number of times a signal changes state per second. For signals with only two possible states one baud is equivalent to one bit per second.
- 6BANDWIDTHa range of frequencies within a given band, in particular that used for transmitting a signal.
- 7PARITY BITa bit which acts as a check on a set of binary values, calculated in such a way that the number of 1s in the set plus the parity bit should always be even (or occasionally, should always be odd).
- 8CHECK DIGITA check digit is a form of redundancy check used for error detection on identification numbers, such as bank account numbers, which are used in an application where they will at least sometimes be input manually. It is analogous to a binary parity bit used to check for errors in computer-generated data.
- 9CHECK SUMa digit representing the sum of the correct digits in a piece of stored or transmitted digital data, against which later comparisons can be made to detect errors in the data.
- 10ARQAutomatic repeat request, also known as automatic repeat query, is an error-control method for data transmission that uses acknowledgements and timeouts to achieve reliable data transmission over an unreliable service.
- 11WHY IS ERROR CHECKING NEEDEDECC (either "error correction [or correcting] code" or "error checking and correcting") allows data that is being read or transmitted to be checked for errors and, when necessary, corrected on the fly. It differs from parity-checking in that errors are not only detected but also corrected.
