Data Communication and Networking

The simplest goal to be achieved is the transfer of data. A computer network not only allows us for the faster means of data communication but it also helps in accessing programs, databases, and other software or tools that are distant from our approach.
A simple network comprises of computers, network operating system software, cable (wiring) to connect the devices, network interface cards, switches and a router (Laudon, Laudon 299). Almost all the businesses nowadays use spreadsheets, word pads etc. to store their germane information which might also be needed by other departments of that companies and the interruption in transporting this information may cause some hindrances for the organization that might lead to ineffective and inefficient production. Connecting all the computers of that organization within and outside departments really helps a lot in increasing the competitive advantage of the organization as the data will be available on time. In addition, networking also helps in reducing the cost of saving work in different soft copies and hard copies since it allows the sharing of work.
Networking is the buzz word these days. …
The data were stored on punch cards and they were the only source of transferring data from one computer to another. In 1960s multi-terminal mainframes were used which were pretty faster. Multiple users used to be connected through a single mainframe with a very good response time of the computers. This computing technique gave birth to the modern form of networking and the concepts of "client" and "server". "This model refers to the client-server relationship. The server is the one specialized powerful computer that provides the information that the client computers require. The client is the computer initiating the inquiry" (History of networking 1). Next, came the era of minicomputers.
