-Describe the features of a simple network and the network infrastructure for a large company.
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. The networking infrastructure for a large company relies on both public and private infrastructures to ...view middle of the document...
This collection of networks evolved from two fundamentally different types of networks: telephone networks and computer networks.
-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.
