Telecommunication - the transmission of signals over a distance for the purpose of communication. Networking This technology connects various computer systems. Because a communications signal is actually a complex waveessentially the sum of a number of component sine waves, all of which have their own precise amplitudes and phasesthe rate of variation of the complex wave can be measured by the frequencies of oscillation of all its components. Since terminals and nodes are connected randomly in the network so this systems route the message along the most efficient paths that take minimum time to send message to the receiver end. They are commonly used in several organizations for linking and enabling communication amongst end-users in the office, different departments, workgroups, etc. This method of storing the programs on a processor or computer is called the Stored Program Control (SPC) technology. In those years, the technological scheme contributed to the integration of the Ethiopian society when the extensive open wire line system was Transmission over electric wire, radio wave, and optical fibre is discussed in telecommunications media.
