Which wireless transmission media requires line-of-sight transmission?

What is the role of a wireless access point in a network?

Which component of a satellite communication system amplifies and broadcasts microwave signals?

has responsibility of transferring datagram from one node to physically adjacent node over a link

Link transmission rate= link capacity = link bandwidth

What is the responsibility of the link layer?

Which of the following is NOT considered a node in the context of the link layer?

Broadcast channels: connect multiple hosts in and hybrid fiber-coaxial cable (HFC)) access networks.

IP addresses in frame headers identify source, destination

Which service provided by the link-layer protocol involves encapsulating datagrams into frames and adding header fields?

What identifies the source and destination on a frame header in the link-layer protocol?

Which service guarantees the error-free movement of each datagram across the link using acknowledgments and retransmissions?

What type of links typically provide the reliable delivery service in the link-layer protocol?

Which service in the link-layer protocol involves coordinating frame transmissions on a shared broadcast link?

What determines exactly where errors have occurred in a frame and corrects those errors in the link layer?

In full-duplex communication, nodes at both ends of the link can transmit simultaneously.

Which component is responsible for implementing most of the link layer in hardware?

Which side of the communication link performs error detection based on the error checking bits added by the sending side?
