Worksheets1.2 OSI & TCP IP Models Quiz
Total questions: 10
Worksheet time: 3mins
Why must two nodes run the same protocols at each layer to communicate?
To ensure they can understand and exchange data correctly.
To increase the speed of data transfer.
To reduce the cost of communication.
To prevent viruses from spreading.
What happens when a protocol at a specific layer encapsulates the data payload received from the next-higher layer with a header?
It creates a protocol data unit (PDU)
It deletes the data
It encrypts the data
It compresses the data
Why is the application layer important for network communication?
It allows software programs and network hosts to exchange data using lower-level protocols.
It manages the physical hardware of the network.
It is responsible for error correction and retransmission.
It encrypts all data before transmission.
Which of the following is NOT typically handled by the presentation layer?
File format conversion
Character set translation
Routing data packets
Data encryption
If a network application needs to ensure that a dialog is properly established, maintained, and ended between two devices, which OSI layer is primarily responsible for this?
Data Link
Session
Physical
Network
What is the main function of the transport layer in data communication?
Encrypting data for security
Managing the end-to-end exchange of data
Converting data into electrical signals
Storing data for future use
Explain why the network layer is essential for communication between different networks on the Internet.
It encrypts all data for security
It identifies and routes data using IP addresses, allowing data to move between different networks
It manages user authentication
It compresses data for faster transmission
What does the data link layer header identify within a network segment?
Source and destination hardware address
Source and destination IP address
Source and destination port number
Source and destination application
How is data delivered to the Physical layer encoded before transmission?
As hexadecimal numbers
As binary numbers (0 or 1)
As decimal numbers
As ASCII characters
What is the correct order of the OSI model layers from bottom to top?
Physical, Data Link, Network, Transport, Session, Presentation, Application
Application, Presentation, Session, Transport, Network, Data Link, Physical
Data Link, Physical, Network, Transport, Session, Presentation, Application
Network, Data Link, Physical, Application, Presentation, Session, Transport
