Quiz 1: Introducing Tcp/Ip

What do most analyzers have that indicate unusual network events or errors? A)ports B)alarms C)sockets D)sessions Enter the appropriate word(s) to complete the statement.

The ____________________ layer also coordinates the sending and receiving of signals across the networking medium, and determines what kinds of cables, connectors, and network interfaces must be used to access a specific area on a network.

The primary function of the ____________________ layer is to provide a globally unique address to every host on the Internet and paths to and from hosts.

____________________ involves cutting up a big message into a numbered sequence of chunks, called segments, in which each chunk represents the maximum data payload that the network media can carry between sender and receiver.

The Session layer includes mechanisms to maintain reliable ongoing conversations, called ____________________.
