This is a QR code. A QR Code is a 2-dimensional barcode, which has encoded in it a URL (web address), text, or other information. It can be read by a QR code scanner, including QR scanner smartphone apps. Once you have an app installed on your smartphone, open the app and hold your phones camera over a QR code to read it. Most QR codes youll come across have a URL encoded, so chances are when you read the QR code it will take you to a web page.

"The TCP demo-applet simulates a single directional unicast data transmission in a number of problematic scenarios. Although there are many factors that cause TCP to decease its transmission speed, I chose to focus on three problems: long delays, asymmetric networks, and errors. These problems are common on media that were not originally designed for interactive data communications such as satellites and cable-modems. A well planned 10/100 base Ethernet LAN should not experience any of these problems. By changing the controls in the applet, the user can see the actual bandwidth that TCP enables in various network scenarios. The actual bandwidth value is calculated based on the formulas presented below". Quoted from the site.
A nice simulation for students to use to test transmission speeds, with the introduction of errors on the communication line. Some background knowledge is required in order to understand what is going on, but this would be a nice add-on to a lecture on TCP.

I don't understand this simulation.
The picture shows no satellite or cable modem device. What am I looking at? Changing the parameters affected nothing else in the simulation. Perhaps, it's me. i just don't know how to use. it.

Applet is easy to use. Concept applies to higher level TCP/IP study. Not applicable for intro courses. Good visual bandwidth representation.
