ENVS 1200 Lecture 22 Notes – Prevalent Implementation
Introduction
• Basic concepts are more stable and evolutionary.
• Even so, most of our specific examples in this chapter and the next are based on TCP/IP
and Ethernet, the prevalent implementations of network technology at present and for
the foreseeable future.
• The importance of networking as a major impact on modern business processes and
user access to knowledge
• Networking makes collaboration and cooperation between organizations possible and
practical. It provides new marketing, research, and sales channels.
• There are many who would argue that the Internet is the most important social and
business tool ever created.
• As such, networking is an essential element in the study of computer system
infrastructure.
• Three simple examples of network models, offering a first look at some of the criteria
and requirements that form the basis for networking.
• As an overview to the fundamental concepts of data communication and networking
• It introduces the general requirements and considerations that a network must meet to
be effective and useful
• As well as common components and common terminology that are basic to network
technology.
• Expands the discussions to explore communication models with the capability to
manage multiple nodes, support and provide transparent conversion for a variety of
channel technologies, share channel resources, and provide international network
addressing capability.
• This discussion focuses primarily on the TCP/IP model that defines nearly every modern
network and the Internet as well.
