OSI Network Layers Quiz - Quiz

An amazing "OSI Network Layer Quiz" is here for you. The International Standards Organization (ISO) developed the Open Systems Interconnection (OSI) model, which divides network communication into seven layers. Layers 1-4 are considered the lower layers and mostly concern themselves with moving data around, whereas Layers 5-7 are the upper layers and contain application-level data. The quiz is here to test your knowledge of the OSI Reference Model in Computer Networking. Give it a try!
