Data Transmission and Protocols

The video explains how email messages are transmitted over the internet using Internet Protocol. It covers the translation of human language into electronic signals, the role of communication protocols, and the layers involved in data transmission. The process of breaking down messages into data packets and their journey through the protocol stack is detailed. Finally, it describes how the receiving computer reconstructs the message.

What is the first step in sending an email message?

• Converting it into a physical signal

• Sending it directly to the recipient

• Translating it from human language to electronic signals

• Breaking it into packets

Which layer is responsible for creating the message in the protocol stack?

• Physical layer

• Application layer

• Internet layer
