World of Computer Networking Your CCNA start - Open Systems Interconnection (OSI) Model

The video tutorial explains the differences between the TCP/IP and OSI models, highlighting the OSI model's seven layers for better educational understanding. Each layer, from application to physical, is discussed in detail, with examples of protocols and functions. The tutorial emphasizes the flexibility of models and the presence of protocols in various layers.

What is the primary advantage of the OSI model over the TCP/IP model?

• It provides a clearer educational framework.

• It is more widely used in practice.

• It has fewer layers.

• It is faster in data transmission.

Which layer of the OSI model is responsible for data encryption and compression?

• Application Layer

• Session Layer

• Transport Layer

• Presentation Layer

Which application belongs to the Application Layer of the OSI model?

• Ethernet

• TCP

• Google Chrome

• IP

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

• Data encryption

• Session establishment and termination

• Routing data

• Physical addressing

Which protocols are associated with the Transport Layer in the OSI model?

• HTTP and HTTPS

• TCP and UDP

• IP and ICMP

• FTP and SMTP

What is the primary responsibility of the Network Layer in the OSI model?

• Data encryption

• Physical data transmission

• Session management

• Routing data from source to destination

Which sublayer of the Data Link Layer is responsible for physical addressing?

• Logical Link Control (LLC)

• Media Access Control (MAC)

• Transport Control Protocol (TCP)

• Network Control Protocol (NCP)
