Document Summary

Analogue signals - continuous waves that transmit information by altering the characteristics of the waves. Analogue signals have two parameters, amplitude and frequency. Digital signals - discrete pulses that are either on or off, representing a series of bits (0s and 1s) which can be interpreted by computers. The function of modems is to convert digital signals to analog signals a process called modulation and analogue signals to digital signals a process called demodulation three types of modems: dial-up modems, cable modems, and dsl modems. Communications channels the medium required to communicate data from one location to another. Two types of medium: cable/wireline and broadcast/wireless. Transmission technologies transmit high volume data quickly and accurately. Most large corporations use 10-gigabit ethernet, where the network provides data transmission speeds of 10 gigabits. The transmission control protocol/ internet protocol (tcp/ip) is the protocol of the. The internet protocol (ip) is responsible for disassembling, delivering, and reassembling the data during transmission.
