• True

• False

Most large communications companies have their own dedicated backbones connecting various regions. In each region, the company has a Point of Presence (POP).

• True

• False

Routers are specialized computers that send your messages and those of every other Internet user speeding to their destinations along thousands of pathways.

• True

• False

In performing these two jobs, a router is extremely useful in dealing with two separate ____. It joins the two networks, passing information from one to the other.

• Computer networks

• Destinations

• ISPs

• Routers

All of these networks rely on NAPs, backbones and modems to talk to each other.

• True

• False

A router has two separate, but related, jobs:

• It ensures that information doesn't go where it's not needed. This is crucial for keeping large volumes of data from clogging the connections of "innocent bystanders."
• It makes sure that _________ it to the intended destination.

What is incredible about this process is that a message can leave one computer and travel halfway across the world through several different networks and arrive at another ______  in a fraction of a second!

• Modem

• Router

• Computer

• ISP

The amazing thing here is that there is no overall controlling network. Instead, there are several ________ networks connecting to each other through Network Access Points or NAPs

• High-level

• Low-level

• Multi-level

• Hierarchal

ISP is short for: Internet Service Protocol

• True

• False

The Internet Society, a non-profit group established in 1982, oversees the formation of the policies and protocols that define how we use and interact with the Internet.

• True

• False

Every computer that is connected to the Internet is part of a corporate owned network, even the one in your home.

• True

• False

The Internet Society, an eclectic techno group established in 1992, oversees the formation of the policies and protocols that define how we use and interact with the Internet.

• True

• False

Most large communications companies have their own dedicated backbones connecting various regions. In each region, the company has a Point of Protocol (POP).

• True

• False

The _________ determine where to send information from one computer to another.

• ISPs

• Routers

• Modems

• NAPs

The POP is a place for local users to access the company's network, often through a local phone number or ________ line.

• Truncated

• Open

• Cable

• Dedicated

Routers also protect the networks from ______, and preventing the traffic on one from unnecessarily spilling over to the other.

• Crosstalk

• One another

• Line noise

• Passing error data

Every computer that is connected to the Internet is part of a Local Area Network, (LAN), even the one in your home.

• True

• False

Routers are specialized computers that codify your messages and those of every other Internet user speeding to their destinations along thousands of pathways.

• True

• False

All of these networks rely on NAPs, backbones and ________ to talk to each other.

• Routers

• LANs

• POPs

• Modems

Routers are mini computers that send your messages and those of every other Internet user speeding to their destinations along thousands of pathways.

• True

• False

Here's an example. Imagine that Company A is a large ISP. In each major city, Company A has a POP. The POP in each city is a rack full of modems that the ISP's customers dial into. Company A leases fiber optic lines from the phone company to connect the POPs together (see, for example, this UUNET Data Center Connectivity Map).Imagine that Company B is a corporate ISP. Company B builds large buildings in major cities and corporations locate their Internet server machines in these buildings. Company B is such a large company that it runs its own fiber optic lines between its buildings so that they are all interconnected.In this arrangement, all of Company A's customers can talk to each other, and all of Company B's customers can talk to each other, but there is no way for Company A's customers and Company B's customers to intercommunicate. Therefore, Company A and Company B both agree to connect to _______ in various cities, and traffic between the two companies flows between the networks at the NAPs.

• POPs

• LANs

• Backbones

• NAPs
