Week 8 Post: More to see with TCP/IP

Most people have probably heard or seen the term TCP/IP, whether in conversation or by reading and seeing it. A simple Google search would tell you that TCP/IP is "a set of rules that governs the connection of computer systems to the internet." when in reality, there are much deeper layers to what it is and how it works.

There are four layers to TCP/IP, and at the basic level can be described:

Link Layer: Moves packets between internet interfaces of two different hosts on the same link.

Internet Layer: This makes internetworking possible and establishes the internet.

Transport Layer: Establishes data channels for task-specific data exchanges.

Application Layer: Includes the protocols used by most apps for user services. At this level, establishes between user protocols and support protocols.

There is a deep knowledge of this topic and it would not be feasible to fit it all on here, but at the base level, you now see that there is more to TCP/IP.
