You will also become familiar with Request for Comments RFC documents, which are standards that define all of the Internet protocols. The concepts presented in this course will provide you with the background information needed to develop network applications, take a network certification course, or communicate with other networks neighboring your LAN.

In life, protocols define the way we interact with other people - for example, the way we behave in a public place. In computer science, protocols are formal sets of rules that dictate the ways in which computers communicate with one another over a network medium. Protocols constitute the backbone of networking.

The application layer is where all network processes and applications run. Finally, we will discuss socket programming and how it can be used to develop network applications. When we talk about networks, we are talking about data transport. Each application relies on the transport layer that is described in this unit.

The International Journal for the Computer and Telecommunications Industry

It is a key layer in today's networks as it contains all the mechanisms necessary to provide a reliable delivery of data over any unreliable network. First, we will develop a simple reliable transport layer protocol. These protocols are the fundamental protocols for modern multimedia applications over the Internet.

In this unit, we will learn how packets groupings of data travel on a network and how each machine can be addressed uniquely so that data transport between two nodes is reliable. We will learn that networks can run out of space, meaning that unique addresses for different machines are no longer available. In these situations, computer scientists must manage IP addressing using CIDR and subnetting - techniques we will learn about in this unit.

The network layer is responsible for the delivery of packets from any source to any destination through intermediate routers. This unit will explain how you can address machines on a network from that layer, use IP addresses to determine physical addresses, and identify the different mechanisms in the link layer that can correct packet collisions when data is transferred over the wire.

This unit guides you through the principles of the link layer. Then the textbook will direct your focus to computer networks with a discussion of how multiple hosts share one transmission medium. The chapter ends with a detailed discussion of the two types of computer networks that are important today from a deployment perspective: Ethernet and WiFi. Multimedia over the Internet becomes more and more popular. This unit guides you through the protocols for transmitting multimedia content, such as voice and video, over the Internet, and discusses security, reliability, and fault tolerance issues related to Internet applications.

You will also be introduced to one of the most recent Internet-based technologies: cloud computation, and we will briefly discuss network remote access and directory services.
