WN-Network Layer in the Internet

1. What is the main function of the network layer in the internet?

• To provide a means of communication between different networks
• To provide a means of communication within a single network
• To provide a means of communication between end devices
• To provide a means of communication between end users

2. What is the main difference between the network layer and the data link layer?

• The network layer provides end-to-end communication while the data link layer provides communication between adjacent devices
• The network layer provides communication within a single network while the data link layer provides communication between different networks
• The network layer provides communication between end users while the data link layer provides communication between end devices
• The network layer provides communication between end devices while the data link layer provides communication between end users

3. What is the main responsibility of the network layer in routing data?

• To determine the most efficient path for data to follow from source to destination
• To determine the fastest path for data to follow from source to destination
• To determine the most secure path for data to follow from source to destination
• To determine the path with the least latency for data to follow from source to destination

4. What is the main protocol used by the network layer in the internet?

• TCP
• IP
• UDP
• HTTP

5. What is the main difference between unicast, broadcast, and multicast communication at the network layer?

• Unicast communication is between two devices, broadcast communication is between all devices in a network, and multicast communication is between a group of devices
• Unicast communication is between all devices in a network, broadcast communication is between two devices, and multicast communication is between a group of devices
• Unicast communication is between a group of devices, broadcast communication is between two devices, and multicast communication is between all devices in a network
• Unicast communication is between two devices, broadcast communication is between a group of devices, and multicast communication is between all devices in a network

6. What is the main purpose of the network layer addressing scheme?

• To identify individual devices in a network
• To identify individual networks
• To identify individual users
• To identify individual applications

7. What is the main difference between connection-oriented and connectionless communication at the network layer?

• Connection-oriented communication requires a setup phase while connectionless communication does not
• Connection-oriented communication is more reliable than connectionless communication
• Connection-oriented communication is faster than connectionless communication
• Connection-oriented communication is more secure than connectionless communication

8. What is the main difference between IPv4 and IPv6 at the network layer?

• IPv4 has a larger address space than IPv6
• IPv4 has a smaller address space than IPv6
• IPv4 has better security features than IPv6
• IPv4 has more overhead than IPv6

9. What is the main function of the network layer in handling errors in the transmission of data?

• To detect and correct errors in the transmission of data
• To prevent errors in the transmission of data
• To conceal errors in the transmission of data
• To ignore errors in the transmission of data
