Summary

In this chapter, you learned the basics and applications of the Transmission Control Protocol/Internet Protocol (TCP/IP) suite. First of all, you learned how TCP/IP works and about the various parts that make up TCP/ IP. Then, you learned about the Transport Control Protocol, the first part of TCP/IP, and how it is used to transport data within TCP/IP. Following that, you learned how the Network layer protocol IP is used.

In addition to these two protocols, you also learned of the various application protocols (like SMTP, FTP, and HTTP) and how they worked. Relating very closely to that was the idea of ports and sockets for each protocol and how each port was mapped to a specific protocol or was specified for each.

One concept that gives many people trouble is the concept of TCP/IP addressing, which was covered in this chapter for both IPv4 and IPv6. Also, those addresses must be resolved into “friendly” names, which was covered in the “Name Resolution Methods” section.

Also in this chapter, you learned how to configure TCP/IP on a Windowsbased workstation and all the steps to do so. Finally, you learned about Virtual LAN (VLAN) technologies and how they work within a network.
