- 1Byte8 bits in a byte
- 2AlgorithmA sequence of instructions used to solve a problem
- 3Data TypesInteger data
Real data
String data
Boolean data - 4BinaryThis is a number system made up of two numbers: 1 and 0
- 5DatabaseAn organized collection of data, generally stored and accessed electronically from a computer system.
- 6NetworksLocal area network (LAN)

- 8simplex transmissiondata travels in one direction only
- 9half duplex transmissionData can travel in both directions along a single cable but not simultaneously
- 10full duplexdata can travel in both directions simultaneously using two cables
- 11bit ratethe number of bits per second that can be transmitted along a digital network
- 12bauda unit of transmission speed equal to the number of times a signal changes state per second
- 13parity 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
- 14check digitA check digit is a form of redundancy check used for error detection on identification numbers
- 15check 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.
- 16ARQ Automatic Repeat RequestThis is a protocol for error control in data transmission. When the receiver detects an error in a packet, it automatically requests the transmitter to resend the packet
