Transport Layer's Role in Web Movie

The transport layer doesn't encode movie and sound data in its headers; it handles delivery of the encoded data to the application. It ensures reliable transmission of movie and sound.

Transport Layer and Webpage Display

The transport layer is not responsible for formatting webpages for different devices or browsers; that's the application layer's job.

Transport Layer Phone Addresses

Transport Layer addresses aren't used for VoIP phone identification; rather, VoIP uses protocols to help ensure communication between phones.

Transport Layer and Multiple Browsers

The transport layer ensures that each browser window gets the webpages it needs, tracking different connections through port numbers and protocol-based flow control.

Study Notes

Transport Layer Functionality

Web Movie Playback: A student plays a short web-based movie; the movie and sound are encoded within the transport layer header.
Web Page Display: An employee accesses a web server on the corporate network. The transport layer formats the webpage for proper display on any device.
VoIP Call: A student uses a VoIP phone to call home. The phone's unique identifier (transport layer address) lets devices on the same network connect.
Multiple Web Page Access: A student has two web browser windows open to different sites. The transport layer delivers the correct page to the correct window.
