Question

• The networking infrastructure for a large company relies on both public and private infrastructures to support the movement of information across diverse technological platforms. It includes the traditional telephone system, mobile cellular communication, wireless local-area networks, videoconferencing systems, a corporate Website, intranets, extranets, and an array of local and wide-area networks, including the Internet. This collection of networks evolved from two fundamentally different types of networks: telephone networks and computer networks. Speculate about whether or not these two networks will remain distinct as we move into the next generation, and describe the implications for business in either case.

Explanation / Answer

A simple network consists of two or more connected computers. Basic network components include computers, network interfaces, a connection medium, network operating system software, and either a hub or a switch.

Name and describe the principal technologies and trends that have shaped contemporary telecommunications systems.

Client/Server computing, the use of packet switching, and the development of widely used communications standards such as TCP/IP are the three technologies that have shaped contemporary telecommunications systems.

Client/Server computing has extended to networking departments, workgroups, factory floors, and other parts of the business that could not be served by a centralized architecture. The Internet is based on client/server computing. Packet Switching technology allows nearly full use of almost all available lines and capacity. This was not possible with the traditional dedicated circuit-switching techniques that were used in the past. Having a set of protocols for connecting diverse hardware and software components has provided a universally agreed upon method for data transmission. TCP/IP is a suite of protocols that has become the dominant.
