- For example, in the email address "example@gmail.com":
- The local part is "example".
- The @ symbol separates the local part from the domain part.
- The domain part is "gmail.com".
To summarize, an email address has three parts: the local part, the @ symbol, and the domain part.

Parts of an e-mail:
There are several essential parts of an e-mail that work together to ensure successful communication. These include:
1. Username:
- The username is the unique identifier for an individual or organization sending the e-mail.

- The "@" symbol separates the username from the domain name in an e-mail address.
- It is a crucial component that indicates the recipient's e-mail address.
3. Host server name:
- The host server name is the domain name that follows the "@" symbol in an e-mail address.
- It represents the server where the recipient's e-mail account is hosted.
4. All of these:
- The correct answer is "All of these" because all three components mentioned above are necessary for a complete and valid e-mail address.
In summary, an e-mail consists of a username, the "@" symbol, and the host server name. These components work together to identify the sender, recipient, and the server where the recipient's e-mail account is hosted.

Explanation:
The correct answer is A: Organization. Here is the detailed explanation:
Domain Name:
- A domain name is the unique address of a website on the internet. It is used to identify and locate websites.

- However, it is not restricted to non-profit organizations anymore and can be used by any individual or entity.
Options:
- B: Orbit - This is incorrect as the domain name "org" is not derived from the word "Orbit".
- C: Non-profit organization - This is partially correct as ".org" was initially intended for non-profit organizations, but it is now open to all.
- D: None of these - This is incorrect as the correct answer is A: Organization.
