Data communication Data communication is the transfer, transmission or switching of digital data/ information from oneend computer device to another electronic device via a communications device (any machine that is capable of assisting in the data transmission), i.e. cable, modems and ports. In any data communication process, at least three elements such as information source, information transmission channel, and an information destination are key. However, circuit switching and packet switching are the only two key types of data switching (Benedetto S.

, and Biglieri E., 2008).The commonly media used in computer communication are categorized into bounded and unbounded media. Bounded media are the physical connections that make up a network system. These physical media are the most reliable for message sending, and they do provide faster data communication through high speed transfer of signals over long distances. Examples include coaxial cable, twisted pair cable and the fiber optic. The unbound media literally use the wireless connections and the transmission done via electronic waves (Odom W., Healy R., and Donohue D., 2010). Data Communication Protocols are a combination of both hardware and software standards that are established to effectively govern data transmission between computers. I.e.

, TCP/IP is a collection of different communication protocols based on IP and TCP. The TCP (Transmission Control Protocols) is applied in the transmission of data from an application to the network systems after breaking down data into IP packets before the transmission and assembling of the packets immediately they are received on the destination end. IP (Internet Protocol), however, protects the communication with other computer devices by sending and receiving the data packets over the internet (Clark A. P., 1983).
