The Internet Unit Review

The basic purpose of the internet is...

• to protect private information

• to store data

• to send info from on computer to another

• to connect input and output devices

What is the Internet Protocol (IP)?

• a set of rules for acceptable internet behavior

• a law that states the internet is for everyone

• a protocol that defines the structure of an internet address and assigns a unique address to every device on the internet

• a set limit on the number of computers allowed to connect to the internet

Check all the CORRECT statements about the internet (there are 3)

• there are no negative consequences of the internet

• the internet helps people communicate

• the internet helps people collaborate to solve problems

• the internet connects devices and networks all over the world

What is a router?

• a device to connect computers and choose the path information takes from one computer to another.

• connects wireless devices, like headphones and speakers

• translate a websites name into an IP address

• increase the speed of a networks connection

Two computers are built by different manufacturers. Which of the following best describes whether these two computers can communicate with each other across the Internet?

• The computers can communicate directly because Internet communication uses standard protocols that are used by all computers on the Internet.

• The computers can communicate, but additional hardware is needed to convert data packets from one computer’s protocol to the other computer’s protocol.

• The computers can communicate directly only if the messages consist of text. Other formats cannot be interpreted across computers.

• The computers cannot communicate, because different manufacturers use different communication protocols.

Which of the following is a benefit of the fault-tolerant nature of Internet routing?

• The ability to use multiple protocols such as hypertext transfer protocol (HTTP), Internet protocol (IP), and simple mail transfer protocol (SMTP) to transfer data.

• The ability to resolve errors in domain name system (DNS) lookups

• The ability to provide data transmission even when some connections between routers have failed

• The ability to use a hierarchical naming system to avoid naming conflicts

According to the domain name system (DNS), which of the following is a valid subdomain of the domain example.com?

• about.example.com

• example.com/about.html

• example.com.about

• example.org

What does it mean for a routing system to be 'redundant'?

• it means that there is more than one path between two points in the network.

• it means if one router goes down then the internet would crash.

• it means multiple packets are sent over the network.

• it means each computer is assigned its own address

What information is contained in a packet?

• The entirety of a digital message, and metadata about the message, including where it came from and where it is going.

• A small part of a digital message, and metadata about the message, including where it came from and where it is going

Which of the following best explains what happens when a new device is connected to the Internet?

• A packet number is assigned to the device.

• A Web site is assigned to the device.

• A device driver is assigned to the device.

• An Internet Protocol (IP) address is assigned to the device.
