Question: In <a href="mailto:[email protected]">[email protected]</a>, what is abc?

Answer:

In the email address "[email protected]," "abc" refers to the username or identifier of the email account. It is the part of the email address that comes before the "@" symbol. The username is chosen by the email account owner and can be a combination of letters, numbers, and sometimes special characters.

In this case, "abc" is the chosen username for the Gmail email account. Gmail is a popular email service provided by Google, and "gmail.com" represents the domain name associated with the email service. Together, the username and domain form a unique email address that allows individuals to send and receive emails.
