Unix TCP/IP was developed by DARPA for internet working and encompasses both network layer and transport layer protocols While TCP and IP specify two protocols at specific protocol layers, TCP/IP is

universal time A coordinated time scale, maintained by the Bureau International des Poids et Mesures (BIPM), which forms the basis of a coordinated dissemination of standard frequencies and time signals UTC is derived from International Atomic Time (TAI) by the addition of a whole number of "leap seconds" to synchronize it with Universal Time (UT1), thus allowing for the eccentricity of the Earth"s orbit, the rotational axis tilt (23.5 degrees), but still showing the Earth"s irregular rotation, on which UT1 is based The Coordinated Universal Time is expressed using a 24-hour clock and uses the Gregorian calendar It is used for aeroplane and ship navigation, where it also sometimes known by the military name, "Zulu time" "Zulu" in the phonetic alphabet stands for "Z" which stands for longitude zero UV Undervoltage WEI Weak end infeed logic VT Voltage transformer X.21 A digital signalling interface primarily used for telecom equipment 3IO Three times zero-sequence current Often referred to as the residual or the earth-fault current 3UO Three times the zero sequence voltage Often referred to as the residual voltage or the neutral point voltage 893 Glossary 894 Chapter 21
