[amp_mcq option1=”An email id cannot have both, lower-case and upper-case letters” option2=”An email id is always unique” option3=”An email id is generally case-sensitive” option4=”An email id cannot use dot (.) character” correct=”option3″]
The correct answer is: C. An email id is generally case-sensitive.
An email address is a unique identifier that is used to send and receive emails. It is typically composed of a username and a domain name, separated by the @ sign. For example, my email address is [email protected]
The username is the part of the email address that comes before the @ sign. It can be any combination of letters, numbers, and underscores. The domain name is the part of the email address that comes after the @ sign. It is the name of the website or organization that hosts the email account.
Email addresses are generally case-sensitive, which means that the case of the letters in the username matters. For example, [email protected] and [email protected] are two different email addresses.
There are a few exceptions to the case-sensitivity rule. Some email providers allow users to create email addresses with mixed case usernames. Additionally, some email addresses are case-insensitive by default, but can be made case-sensitive by the user.
It is important to note that not all email providers use the same rules for email addresses. Some providers may have different restrictions on the length of usernames, the use of special characters, and other factors. It is always best to check with your email provider for specific information about their email address policies.
