As a region with volcanic activity, Indonesia has mountain ranges, with its highest peak on Papua, with Puncak Jaya, standing 4,884 meters (16,024 feet) above sea level. Major rivers in Indonesia include the Mahakam and Barito rivers, and the country's largest lake is Lake Toba in Sumatra.
To compensate, analog signals are amplified, ad digital signals are regenerated through repeaters. In a Half-duplex transmission, signals can travel in both directions over a medium BUT in only one direction at a time. When signals can travel in both directions over a medium simultaneously, the transmission is considered full duplex. A form of transmission that allows multiple signals to travel simultaneously over one medium is known as multiplexing. In multiplexing, the single medium is logically separated into multiple channels, or sub channels. Throughput is the amount of data that the medium can transmit during a given period of time.
In telecommunications, frequency-division multiplexing is a technique by which the total bandwidth available in a communication medium is divided into a series of non-overlapping frequency bands, each of which is used to carry a separate signal. This allows a single transmission medium such as a cable or optical fiber to be shared by multiple independent signals. Another use is to carry separate serial bits or segments of a higher rate signal in parallel. The most natural example of frequency-di
