Exam 5: Network and Transport Layers

What is DHCP and why would network managers want to use it?

Connectionless routing sets up a TCP connection, or virtual circuit between a sender and receiver.

The ____________ layer links the application layer with the network layer is responsible for end-to-end delivery of messages.

An) ________ refers to a group of computers that are logically grouped together by IP number.

A destination port number at the transport layer identifies which application on a computer should receive the data transmission.

IGMP refers to:

The ______ defines what type of packets should be routed and what types of packets should be discarded.

Because there is a limit on the length of a frame that the data link layer can transmit from node to node, the transport layer breaks up the message from the application layer into several smaller segments.

______________ communication is most commonly used when the application data or message can fit into one single packet.

____________ refers to the type of routing in which the routing table is developed by the network manager and modifications are made only when computers are added to or removed from the network.

Suppose a client computer wants to access a web page on a web server.Assume that it knows all of the IP addresses and data link layer addresses in the network, except those for the web server itself.Describe how the client would obtain the IP address for the web server.

Explain how the client computer in the LAN figure in the book Figure 5.15) would obtain the data link layer address of its subnet gateway.

What does the network layer do? Where does it sit in relationship to the other four layers of our simplified network model?

A multicast message can be used to send a message to a maximum of two other computers.

An example of an application layer address is HYPERLINK "http://www.indiana.edu" www.indiana.edu.

Connections on a router, to the Internet and other routers for example, are called applications.

With ________ routing, computers or routers count the number of hops along a route and periodically exchange information on the hop count with their neighbors.

_______ is the dominant network protocol today and is in use in virtually every LAN and WAN in the world.

_______________ is a type of dynamic routing.

___________ is the translation of application layer addresses into IP addresses.
