Networks are trusted to carry all of our sensitive information, the protocols that are used to carry that information are just as important to understand as the networks they are carried across. TCP and IP are two of the main protocols that make up all modern networks. These two protocols are crucial topics to understand because they play a vital role in your day to day network usage in your home or office. Network models provide us with a way to understand how all of these protocols fit together and there are two different models that are commonly used and also important to understand: OSI model and the TCP network of these models use layers to describe different parts of a network communication, while rarely used in practice you must understand the layers of both models because they are covered on exams. In this video, certification and cybersecurity expert Mike Chapple breaks down the basics of these network protocols and the models to help you prepare for your exam.
