(182).jpg "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!
