Exam 5: Network and Transport Layers

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.

When TCP/IP translates a network layer address into a data link layer address, it sends a special ____________ to all computers in the subnet.

_________created a service that allows organizations to transfer IPv4 addresses they don't need to another organization.

The data link layer address is generally encoded in a network card by the card's manufacturer.

An Address Resolution Protocol message is broadcast to all computers in a subnet to find the data link layer address.

When TCP/IP translates an application layer address into an IP address, it sends a special __________ to the nearest DNS server.

The most common standard for dynamic addressing for TCP/IP networks is Dynamic Host Control Protocol.

Quality of Service routing is a special type of connection-oriented routing in which different connections are assigned different priorities.

Domain Name Servers provide the equivalent of directory assistance for application layer addresses.

To help determine to which application a transmission should be delivered on a particular computer, TCP uses the application layer port addresses to distinguish among many open applications on a computer

Source port address is the logical address generated by the application layer on the source computer to identify the application, which is sending the data.

List and describe five reasons why TCP/IP has become the predominant protocol for Internet level transport applications.What do you think is the future market share potential for proprietary standards? What are some limitations of TCP/IP in terms of future Internet growth capabilities?

A special type of message that is used when sending the same message to a specific group of computers is called a:

_______________ is a type of dynamic routing.

A type of message that is used when sending a message from one computer to another computer is called a:

What is a virtual circuit?

An autonomous system is a network operated by one organization.

What four pieces of information does a computer using TCP/IP need in order to send messages using TCP/IP.Explain why each of these is required.

TCP is the network layer protocol used on the Internet today.

A special type of message that is used when sending the same message to all computers on a specific LAN or subnet is called a:
