A student has two web browser windows open in order to access two web sites. The transport layer ensures the correct web page is delivered to the correct browser window.A student is playing a short web-based movie with sound. The movie and sound are encoded within the transport layer header.A student is using a classroom VoIP phone to call home. The unique identifier burned into the phone is a transport layer address used to contact another network device on the same network.A corporate worker is accessing a web server located on a corporate network. The transport layer formats the screen so the web page appears properly no matter what device is being used to view the web site.
