What is the primary purpose of the OSI model in network communication?

• To define a set of standards for vendors and technicians to ensure digital communication and software interoperability.

• To encrypt all data transmitted across the internet.

• To assign IP addresses to devices on a network.

• To physically connect devices using cables and Wi-Fi.

Which layer of the OSI model is responsible for encrypting and decrypting data?

• Application Layer

• Session Layer

• Presentation Layer

• Transport Layer

What is the main function of the Network Layer in the OSI model?

• Managing communication sessions between applications.

• Providing source and destination IP addresses and determining the best route for data.

• Converting data into frames for physical transmission.

• Encrypting and decrypting data for secure transmission.

Why is the OSI model still frequently used despite the modern internet being based on the TCP/IP model?

• The OSI model is more secure than the TCP/IP model.

• The OSI model is simpler and easier to implement for small networks.

• The OSI model helps visualize and communicate how networks operate and aids in troubleshooting.

• The TCP/IP model is only used for wireless communication, while OSI is for wired.
