Understanding the OSI Model

What does OSI stand for in the context of networking?

• Online Services Integration

• Operating System Interface

• Open Systems Interconnection

• Open Source Initiative

How many layers are there in the OSI model?

• 3

• 10

• 5

• 7

Which layer of the OSI model is responsible for end-to-end communication?

• Application layer

• Network layer

• Transport layer

• Data Link layer

What is the primary function of the Transport layer in the OSI model?

• To establish physical connections between devices.

• To manage network routing and addressing.

• To encrypt data for secure transmission.

• To provide reliable data transfer between devices.

Which layer of the OSI model deals with data formatting and encryption?

• Network layer

• Transport layer

• Application layer

• Presentation layer

What protocol operates at the Network layer of the OSI model?

• Internet Protocol (IP)

• Transmission Control Protocol (TCP)

• File Transfer Protocol (FTP)

• Hypertext Transfer Protocol (HTTP)

Which layer is responsible for establishing, managing, and terminating sessions?

• Session Layer

• Transport Layer

• Data Link Layer

• Network Layer

What is the main purpose of the Data Link layer in the OSI model?

• To provide node-to-node data transfer and error detection.

• To encrypt data for secure transmission.

• To route data between different networks.

• To manage physical connections between devices.

At which layer does the HTTP protocol operate?

• Network layer

• Transport layer

• Data link layer

• Application layer

What is the role of the Physical layer in the OSI model?

• The Physical layer encrypts data for secure transmission.

• The Physical layer manages error detection and correction.

• The Physical layer establishes end-to-end connections between devices.

• The Physical layer transmits raw bitstreams over a physical medium.
