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 balanced pair operation, the two wires carry equal and opposite signals, and the destination detects the difference between the two. This is known as differential mode transmission. Noise sources introduce signals into the wires by coupling of electric or magnetic fields and tend to couple to both wires equally.
