Data Communication deals with the transmission (sending and receiving) of information between two locations by means of electrical signals. For data communications to occur, the communicating devices must be part of a communication system made of a combination of hardware and software. Answer the following questions in view of explaining the entire phenomenon of transmitting data between devices. (a) i. How does the components of data communication contribute to the success of agood data Communication System ii. Discuss the factors that ensures effective communication to occur.

Answer the following questions in view of explaining the entire phenomenon of transmitting data between devices.
(a) i. How does the components of data communication contribute to the success of agood data Communication System
ii. Discuss the factors that ensures effective communication to occur.
(b) Discuss the concept of Data Flow. Consider the various types of transmission modes
and with the aid of diagrams and practical scenarios explain your answer.
(c) The most familiar type of Data Communication Equipment is the Modem.it modulates an analog carrier signal to encode digital information and also demodulates such a carrier signal to decode the transmitted information. The goal is to produce a signal that can be transmitted easily and decoded to reproduce the original digital data. Briefly describe how these goals are achieved by the modem.
