- network management — (networking) The process of controlling a network so as to maximise its efficiency and productivity. ISO's model divides network management into five categories: fault management, accounting management, configuration management, security management and performance management. Fault management is the process of identifying and locating faults in the network. This could include discovering the existence of the problem, identifying the source, and possibly repairing (or at least isolating the rest of the network from) the problem. Configuration management is the process of identifying, tracking and modifying the setup of devices on the network. This category is extremely important for devices that come with numerous custom settings (e.g. routers and file servers). Security management is the process of controlling (granting, limiting, restricting or denying) access to the network and resources thereon. This could include setting up and managing access lists in routers (creating "firewalls" to keep intruders out), creating and maintaining password access to critical network resources, identifying the points of entry used by intruders and closing them. Performance Management is the process of measuring the performance of various network components. This also includes taking measures to optimise the network for maximum system performance (periodically measuring of the use of network resources).

- phase-shift keying — (communications) (PSK) A digital modulation scheme that conveys data by changing the phase of a carrier wave. The data can either determine the absolute phase relative to the unmodulated carrier or reference signal ("coherent phase-shift keying", CPSK) or the change in phase ("differential phase-shift keying", DPSK). The number of different phases used determines the amount of data that can be transmitted in each cycle. Each cycle can be considered to constitute one "symbol", e.g. with two possible phases, each cycle carries one bit. The more phases that are used, the less tollerant to noise the transmissions becomes. Alternatives to PSK are amplitude-shift keying (ASK) and frequency-shift keying (FSK).
