When sending a message across routers in the Lesson 4 Internet Simulator, your message sometimes jumped multiple routers (for example instead of being sent from Router 1 to 2, it went from Router 1 to 8 to 4 then to 2). What is this concept called?

The Internet Engineering Task Force (IETF) defines the protocols and standards for how the Internet works. The members of the IETF are:

HTTP is considered to be a high level protocol because:

Routers do not monitor current network conditions in determining the fastest route for packets to take in reaching their destinations.

When a packet arrives at a destination computer, an acknowledgement is sent to the sender by the __________, letting them know they don’t need to resend that packet.

The various protocols in use on the internet are said to operate in layers in which the protocol(s) at each layer solve one problem related to networked communication, and higher layers are built on top of, and rely on, the lower layers to do their jobs.

From the list provided choose the two (2) answers that correctly describe which internet protocol relies on the other. For example: if protocol A relies onprotocol B, it means that A is a higher level protocol than B, and thus protocol B must exist and work properly in order for protocol A to do its job.

Select two answers.

What are some reasons your messages might take different paths getting to it's destination?

Which of the following is FALSE regarding packets?

With this protocol in sending packets, split seconds matter more than correcting errors, like video-conferencing, live streaming, online gaming:

With this protocol in sending packets, accuracy matters more than saving a split second, like sending emails, photos, or just browsing websites

When sending packets of information, it will typically include "data about the data" which includes the IP address of both where it came from and who it's going to:

When we talk about the Internet having scalability, we are referring to a system which allows billions of devices to get added to the network without putting pressure on any one computer or server to know all the IP addresses in the world.

When you visit a website you first ask the DNS for the IP address of the domain you want to visit. Other servers never become involved in this process; thus allowing for your messages to travel faster.

Once a message is sent and that website's server is contacted, the __________ code will be sent to your computer which gives instructions on how to display that webpage:

All information is sent over physical wires, cable, wifi networks, and routers that make up the physical network of the Internet.

A group of interconnected computing devices capable of sending or receiving data.

Which of the following best describes the protocols used on the Internet?

Which of the following best describes the purpose of an IP address?

A protocol for sending packets that does error-checking to ensure all packets are received and properly ordered.

A squirrel chews through one of the wires in a network and the network immediately begins using a different path. This is an example of?

The maximum amount of data that can be sent in a fixed amount of time, usually measured in bits per second.

What does HTTP stand for?

The unique number assigned to each device on the Internet.

A protocol for sending packets quickly with minimal error-checking and no resending of dropped packets.

The inclusion of extra components so that a system can continue to work even if individual components fail.

What does DNS stand for?

These act like a traffic manager, deciding what route packets take...

Having different paths for packets to take when traveling across the Internet makes the Internet...

This manages the sending and receiving of all packets sent and received from clients and servers...

Which protocol stresses time as the most important feature and will sacrifice losing a few packets to do so...

Your router does not know the IP address of a website you are trying to get to. What feature of the Internet helps with finding out this information?

What feature of the Internet address the fact that there are not enough unique identifiers for all of the devices connected to the Internet?

A movie from Netflix is being streamed to the TV in your home. Even after being compressed, the movie file is huge. For this reason, it is chopped up into little pieces and sent through the Internet to your house. What are these little pieces of data called?

When you type in the address for a website, called a URL, the server hosting that website gets a request for information from you. It then sends you all of the data that makes up the website, like text, audio, and other media. This process is called...

What is the language used to display how a website is laid out?

What feature of the Internet reorganizes packets and double-checks they are all received?

Look at the network map shown. At least how many connections must be damaged to prevent the client and the server from communicating?
