CompTIA Network+: The OSI Reference Model

Skillsoft issued completion badges are earned based on viewing the percentage required or receiving a passing score when assessment is required. The Open Systems Interconnection (OSI) model is used to describe how computer systems communicate with each other. The OSI model is split into seven abstract layers and is often used for troubleshooting network problems. In this course, learn about the purpose and features of the OSI model. Next, examine each OSI model layer, including the application, presentation, session, transport, network, data link, and physical layers. Finally, discover 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. This course is one of a collection that helps prepare learners for the CompTIA Network+ (N10-009) certification exam.
