Exam 8: Internet Operation

The maximum number of Class A network addresses is

Two notable consumer electronic gadgets that are impacting the traffic load on networks are the digital versatile disc and the digital still camera.

The Internet and the Internet Protocol is designed to provide differentiated services depending on whether traffic is elastic or inelastic.

Which of the following describes class A networks?

Most IP addresses consist of a network identification and a host identification within that network.

Give one example of an Internet application with elastic traffic,and one of an application with inelastic traffic.

What is a subnet mask?

Subnets are used where the number of networks exceeds the number of hosts within a specific company or organization.

An internet routing protocol is used to exchange information about reachability and traffic delays,allowing each router to construct a next-hop routing table for paths through the internet.

The source and destination address fields in the TCP header each contain a 32-bit Internet address.

A digital versatile disc can store approximately 100 times more data than a CD-ROM.

A QoS facility allows the Internet to treat all classes of traffic equally in order to optimize the services provided to all users.

Which of the following describes class B networks?

Typically,more complex routing protocols are used between autonomous systems within a larger internet and relatively simple routing protocols are used within each autonomous system.

Which of the following describes class C networks?

The left-most bits of a IP address determine whether it is Class A,B,or C.
