Frequency-division multiple access (FDMA) is a channel access method used in some multiple-access protocols. FDMA allows multiple users to send data through a single communication channel, such as a coaxial cable or microwave beam, by dividing the bandwidth of the channel into separate non-overlapping frequency sub-channels and allocating each sub-channel to a separate user.

Systems Network Architecture [1] (SNA) is IBM's proprietary networking architecture, created in 1974. [2] It is a complete protocol stack for interconnecting computers and their resources. SNA describes formats and protocols but, in itself, is not a piece of software.
The National Science Foundation Network (NSFNET) was a program of coordinated, evolving projects sponsored by the National Science Foundation (NSF) from 1985 to 1995 to promote advanced research and education networking in the United States. [1] The program created several nationwide backbone computer networks in support of these initiatives ...
Two Nigerian men have been extradited to the U.S. after they were indicted for allegedly sexually extorting teenage boys and young men in Michigan and across the country, a prosecutor said Sunday.
The mobile transmits at the beginning of the time slot as received from the network. If the mobile is near the base station, the propagation delay is short and the initiation can succeed. If, however, the mobile phone is just less than 35 km from the base station, the delay will mean the mobile's transmission arrives at the end of the time slot.
ALOHAnet, also known as the ALOHA System, [1] [2] [3] or simply ALOHA, was a pioneering computer networking system developed at the University of Hawaii.ALOHAnet became operational in June 1971, providing the first public demonstration of a wireless packet data network.
Network architecture is the design of a computer network.It is a framework for the specification of a network's physical components and their functional organization and configuration, its operational principles and procedures, as well as communication protocols used.
