L band is a fequency range between 390MHz and 1.55GHz which is used for satellite communications and for terrestrial communications between satellite equipment. The high frequencies utilized by C band, Ku band, and Ka band would suffer from high signal loss when transported over a copper coax cable such as an Intra-Facility Link. An LNB …
An integrated circuit (IC), also called a microchip, is an electronic circuit etched onto a silicon chip. Their main advantages are low cost, low power, high performance, and very small size. History The integrated circuit was invented in 1958 by Jack Kirby (1923-2005), an American engineer. In 2000, he won the Nobel prize in physics …

Department of Defense Network (DoD) Network Model Introduction Back in 1960, systems were primarily made up of mainframe computers, and were typically owned by fairly large companies and government institutions. Because mainframe computers run different proprietary software, and due to mainframes not being able to communicate between each other, special code (interface) had to be …
VideoGuard is an encryption method that NDS produced. It is used for conditional broadcasting services such as broadband television and the Internet. Since satellites, radio towers, and all other broadcasting equipment broadcast signals without discretion to which subscribers receive them, VideoGuard is necessary in order to distinguish which television channels, Internet features, and other services subscribers are …
The global catalog is a distributed data repository that is stored in global catalog servers and issued via multimaster replication. It basically is composed of a representation (partial) of every object in the multidomain Active Directory forest that can also be searched. The global catalog is used because searches can be made faster because they …
Coaxial cable, also called coax, is used to transmit radio frequency (RF) signals. It has low emission losses and provides protection from electromagnetic interference, allowing signals with low power to be transmitted over longer distances. Coaxial cable is comprised of an inner core, insulator, shield, and outer cover. It is called coaxial because these sections …
