Frequency-hopping spread spectrum (FHSS) is a method of transmitting radio signals by rapidly changing the carrier frequency among many frequencies occupying a large spectral band. The changes are controlled by a code known to both transmitter and receiver. FHSS is used to avoid interference, to prevent eavesdropping, and to enable code-division multiple access (CDMA) communications.

DMX512 is a standard for digital communication networks that are commonly used to control lighting and effects. It was originally intended as a standardized method for controlling stage lighting dimmers, which, prior to DMX512, had employed various incompatible proprietary protocols. It quickly became the primary method for linking controllers to dimmers and special effects devices such as fog machines and intelligent lights.

The 33-centimeter or 900 MHz band is a portion of the UHF radio spectrum internationally allocated to amateur radio on a secondary basis. It ranges from 902 to 928 MHz and is unique to ITU Region 2. It is primarily used for very local communications as opposed to bands lower in frequency. However, very high antennas with high gain have shown 33 centimeters can provide good long-range communications almost equal to systems on lower frequencies such as the 70 centimeter band. The band is also used by industrial, scientific, and medical (ISM) equipment, as well as low-powered unlicensed devices. Amateur stations must accept harmful interference caused by ISM users but may receive protection from unlicensed devices.

A national curriculum is a common programme of study in schools that is designed to ensure nationwide uniformity of content and standards in education. It is usually legislated by the national government, possibly in consultation with state or other regional authorities.

Winston Churchill High School may refer to a number of schools, all named after Winston Churchill, who was Prime Minister of the United Kingdom from 1940 to 1945 and from 1951 to 1955.
Educational stages are subdivisions of formal learning, typically covering early childhood education, primary education, secondary education and tertiary education. The United Nations Educational, Scientific and Cultural Organization (UNESCO) recognizes nine levels of education in its International Standard Classification of Education (ISCED) system. UNESCO's International Bureau of Education maintains a database of country-specific education systems and their stages. Some countries divide levels of study into grades or forms for school children in the same year.
Traffic signal preemption is a system that allows an operator to override the normal operation of traffic lights. The most common use of these systems manipulates traffic signals in the path of an emergency vehicle, halting conflicting traffic and allowing the emergency vehicle right-of-way, thereby reducing response times and enhancing traffic safety. Signal preemption can also be used on tram, light-rail and bus rapid transit systems, to allow public transportation priority access through intersections, and by railroad systems at crossings to prevent collisions.
A state education agency or state department of education is the state-level government organization within each U.S. state or territory responsible for education, including providing information, resources, and technical assistance on educational matters to schools and residents.
