Chapter 3 TCP/IP Networks

What is a TCP/IP protocol?
In the TCP/IP model, there are two defined protocols that can operate in this layer; TCP and UDP. These two protocols provide connection-oriented and con-nectionless communications. Only TCP protocol provides a way of sequencing, such that even if the data segments arrive in a different sequence of which they were sent in, they can be rearranged.
What is Chapter 3 of ccnav7?
Chapter 3. Protocols and Models - Introduction to Networks Companion Guide (CCNAv7) [Book] Upon completion of this chapter, you will be able to answer the following questions: What types of rules are necessary for successful communication? Why are protocols necessary in network communication? What is the purpose of adhering to a protocol suite?
What protocols and interfaces allow TCP/IP traffic to flow over physical networks?
This chapter provides an overview of the protocols and interfaces that allow TCP/IP traffic to flow over various kinds of physical networks. TCP/IP, as an internetwork protocol suite, can operate over a vast number of physical networks. The most common and widely used of these protocols is, of course, Ethernet.
What are the 4 layers of TCP/IP?
Unlike the OSI model, the TCP/IP model consists of four layers; Network Access layer (or sometimes called Host-to-Network layer), Internetwork layer (sometimes known as Internet layer), Transport layer, and Application layer. These four layers are shown in Fig. 3.1.
