ABSTRACT
K band; The portion of the electromagnetic spectrum in the frequency range from about 10 GHz to 12 GHz, and used for satellite communications.
KDC: Key Distribution Centre. Kelvin: The unit of absolute temperature. Absolute zero is at –273o Cel-
sius. Kendal notation: Used in the definition of queues. Generally queues are
categorised by the notation A/B/m/S/P, where these symbols are defined as in Table K.1. The most frequently used interarrival and service distributions are given in Table K.2. Therefore, for example, D/G/1 indicates a queue with deterministic arrivals, general or arbitrary service time, and one server.
