Big Idea 4

How do the World Wide Web and the Internet work together?

• They perform the same functionality

• The web uses HTTP to share web pages using the Internet

• The Internet uses the web to connect to share data

• The Internet is an application that runs using the web

If a fire occurs at a major Internet hub, what is the result?

• Internet traffic will be routed to its destination a different way because of the redundancy built into the Internet

• The part of the globe that is served by that Internet hub will be down because of the end-to-end architecture of the Internet

• Different IP addresses will be assigned to devices that were impacted by the unavailability of the Internet hub

• People can use dedicated phone lines as a backup with no change in service

The time it took to complete a task sequentially was 25 seconds. The time it took to complete the same task using a parallel computing model was 10 seconds. What is the speedup?

• 2.5

• 0.4

• 15

• -15

How do TCP and IP interact?

• IP forwards the data to the ISP to identify which TCP to use.

• TCP hands off control to HTTP, which passes it to IP.

• TCP creates packets from the data to be sent and transfers control to IP for routing. TCP then reassembles the packets at the destination.

• IP uses UDP in conjunction with TCP to securely send data.

An organization collects massive amounts of data, more than they can currently process. What options should they consider using to be able to process their data to gain insights?

Select TWO answers!

• Centralized computing system

• Distributed computing system

• Parallel computing system

• Sequential computing system.

Which TWO protocols are responsible for breaking the data into packets and putting it back together at the destination?

Select TWO answers!

• TCP

• HTTP

• FTP

• UDP

What is bandwidth?

• The amount of data that can be transmitted in a specified amount of time

• The speed at which that data can be downloaded

• The size of the cable that connects homes and businesses to the Internet

• The amount of delay between requesting data and receiving it

Why is the Internet designed to be fault-tolerant?

• So the system doesn't crash when people make typos in their web requests

• So the Internet can keep running even when it has malware

• So it can keep running when sections of it are not working

• So as companies expand to new locations, IP conflicts can be resolved

How do packets know how to get to their destination?

• The router knows the path and sends it step-by-step to its final destination

• Each path has an embedded code that directs the packets to the correct location

• The destination location emits pulses that guide the data packets to its location.

• The destination IP address is included in each packet

What is the minimum number of connections that must be broken or removed in the network before computer A can no longer communicate with computer F?
