To provide addressing for devices
To encapsulate data into frames
In a datagram network, how does the destination node determine the correct order of packets?
By using a global addressing scheme
By using a fixed path for all packets
By maintaining a connection state
By relying on upper-layer protocols to reorder packets
What is the main advantage of using fiber-optic cables over twisted-pair cables?

Higher bandwidth and less signal attenuation
Easier installation
Better compatibility with older systems
Which type of switching allows for dynamic routing between multiple nodes?
Circuit Switching
Message Switching
Virtual Circuit Switching
Packet Switching
What is the purpose of protocol layering in data communication?
To eliminate the need for addressing

To separate different communication tasks into layers
To simplify the physical connections
Which of the following is a characteristic of microwave transmission?
Requires line-of-sight transmission
Can penetrate walls easily
Is primarily used for long-distance radio communication
Operates at very low frequencies
What is the role of a router in a network?
To forward packets based on their destination IP address
To provide physical connections between devices
To connect devices within a LAN
To manage data link layer protocols
What is multiplexing in the context of the TCP/IP protocol suite?
The method of separating data into packets
The technique of error checking in data transmission
The process of establishing a connection between two devices
The process of combining multiple signals into one
