IP Addressing part 3 covers Host addressing and Subnetting. I love this guys accent, I like the way he pronounces router. Part 4 in this series continues on with more subnetting but before I post part 4, I’m going to post another video on subnetting. Subnetting can be a difficult subject for some and I thought a different style of teaching might be helpful.

If you like this video, please click on the tweet icon in the upper right and re-tweet this post. Thanks! Now on with the movie.

I’ve been distracted lately with a prelaunch, Internet marketing and cash gifting is a current interest of mine.  So, until I can get back into the book, I thought I’d post some video’s.
This first video is on IP addressing and it a series of 5 videos.

TCP/IP defines a large collection of protocols that allow computers to communicate.

What is discussed in chapter 2 is very general in nature and will be gone into depth in later chapters.

TCP/IP defines the details of each of these protocols inside documents called Requests for Comments (RFC).

The TCP/IP model represented in column 1 of the table lists the four layers of TCP/IP, and column 2 of the table lists several of the most popular TCP/IP protocols.

The TCP/IP Application Layer

The application layer provides an interface between software running on a
computer and the network itself. The application layer does not define the application itself, but rather it defines services that applications need—such as the capability to transfer a file in the case of HTTP.

Important general concepts behind networking models: when a particular layer on one computer wants to communicate with the same layer on another computer, the two computers use headers to hold the information that they want to communicate. The headers are part of what is transmitted between the two computers. This process is called same-layer interaction.
