There might come a time in your career when the fundamental networking tasks you are now able to perform in your sleep, like subnetting an IP version 4 (IPv4) network, fall into obsolescence. Sure, you were warned. We all were. Although IPv4 addressing is far too ubiquitous to go anywhere anytime soon, and the deployment of IP version 6 (IPv6) has been slow, to say the least, more widespread deployment of IPv6 is coming. Therefore, the ability to understand and implement IPv6 addressing has become a topic contemporaneous on network certification exams, such as the Cisco Certified Network Associate (CCNA) exam, with the ability to understand and implement IPv4 addressing.

This is my third of three blog posts in my "What to Expect" series. This blog post will focus on what happens after you've taken a certification exam.

When my wife became pregnant with our first child, we had no idea what to expect. So we prepared by reading pregnancy books, searching online, taking childbirth classes, and talking to friends who had already gone through the experience. Sure, there were a few things that we weren't prepared for, but we were ready for most of the situations we encountered along the way.

I've got three favorite quotes on preparation:
"Every battle is won before it is ever fought."
- Sun Tzu, The Art of War
"By failing to prepare, you are preparing to fail."
- Benjamin Franklin
"Give me six hours to chop down a tree, and I will spend the first four sharpening the axe."
- Abraham Lincoln

The previous two parts of this blog, Part I and Part II, covered the seven layers of the Open Systems Interconnection (OSI) model. This installment will cover the four layers of the Transmission Control Protocol/Internet Protocol (TCP/IP) model and contrast the TCP/IP model with the OSI model.

In Part I of The Seven Layers of Networking blog, John began a discussion about the layers of the Open Systems Interconnection (OSI) model. The first four layers, which you can read about in that blog, are the Physical layer, the Data Link layer, the Network layer, and the Transport layer. In network discussions, you'll most often encounter the first four layers. The final three layers, the Session layer, the Presentation layer, and the Application layer, are not as commonly discussed but are still essential to a network. This blog will cover those three layers and the encapsulation process that occurs when one host communicates with another. Then you'll have to stay tuned for Part III, which will cover a related-yet-different layered model, the Transmission Control Protocol/Internet Protocol (TCP/IP) model.
