Networking protocols are sets of rules that govern how data is exchanged across a network. Different tasks (web browsing, file transfer, email) use different protocols.

Step 2: Detailed Explanation:


HTTP (Hypertext Transfer Protocol): Used for accessing websites.
FTP (File Transfer Protocol): Used for transferring files between computers.
SMTP (Simple Mail Transfer Protocol): This is the standard protocol specifically designed for sending emails from a client to a server or between servers.
TCP (Transmission Control Protocol): A foundational protocol that ensures reliable delivery of data packets, but it isn't specific to email content.
