The Open Systems Interconnection, or OSI, model is used to describe how computer systems communicate with each other. Frequently used for troubleshooting network problems, the seven layers of the OSI model are concepts with which all networking professionals should be familiar.

In this course, youâll learn about each layer of the OSI model. Youâll outline how human-readable information, such as emails and chat messages, are transferred over a network, as well as the path this information takes along the OSI model.

Youâll also examine data encapsulation and decapsulation within the context of the OSI model. Youâll outline characteristics for Ethernet headers, IP headers, and TCP/UDP headers, and learn to differentiate between synchronization (SYN) and acknowledgement (ACK) flags.

Lastly, youâll recognize the primary differences between maximum transmission unit, or MTU, and maximum segment size, or MSS, and how these concepts relate to data being transmitted over a network.
