The correct answer is POP.

Key Points

• Email protocols are a set of rules defined to ensure the reliable and secure exchange of data between various servers. These protocols define how an email has to be encoded, sent, received and rendered.
• Various protocols are used for email delivery, such as Post-Office Protocol (POP), Internet Message Access Protocol (IMAP), Simple Mail Transfer Protocol (SMTP) etc.
• In POP, the POP client is installed on the recipient system, and the POP server is installed on the recipient's mail server. It is used to retrieve email from an email server for client applications. Hence option 3 is correct.
• POP is an application layer protocol. It supports offline access to email, but to access offline, email has to be downloaded. This protocol is used to retrieve emails for a single client.

Additional Information

• SMTP transfers emails between email clients and servers but primarily for sending emails.
  • It is a transport layer protocol and is sometimes paired with POP and IMAP to retrieve emails. SMTP is reliable because it sends an error message if the mail is not delivered to the receiver.
• IMAP is an application layer protocol used to retrieve mail for multiple clients. It supports both offline access and online access to email.
  • It allows two-way sync of emails between the email server and the email client.
• Multipurpose Internet Mail Extension Protocol (MIME) is a protocol that allows non-ASCII values to be sent through SMTP. 
  • It supports different data like images, videos, audio files, etc., and allows multiple attachments with a single message.

The correct answer is Multiple at signs (@)

Key Points

• Email ID Format: A valid email ID typically follows the format [email protected].
• Multiple @ Signs: ❌ Invalid. An email ID can contain only one @ symbol. Having more than one breaks the standard structure and is not accepted by email systems.
• Multiple Digits: ✅ Valid. Digits 0-9 can be used in any number within the local part of the email.
• Multiple Dots: ✅ Valid if used correctly. Dots can be used in the local part (username), but not at the beginning, end, or consecutively.
• Multiple Underscores: ✅ Valid. Underscores are allowed in the username part of the email.

Additional Information

• Email addresses are governed by RFC 5322 standards.
• Only one @ is permitted, separating the local and domain parts.
• Domain names must follow valid DNS naming conventions.

Hence, the correct answer is: option 4) Multiple at signs (@)

The correct answer is option 4: Cc

Key Points

Cc stands for Carbon Copy. When you add recipients in the Cc field of an email, it means that those people will receive a copy of the email and their addresses will be visible to all other recipients, including the primary recipient (in the "To" field).

Explanation of options:

• Option 1 – Bcc (Blind Carbon Copy): ❌ Used to send copies without revealing the recipient to others.
• Option 2 – Subject: ❌ This is where the title or topic of the email is written, not email addresses.
• Option 3 – To: ❌ This is where the main recipient’s email address goes, not additional recipients.
• Option 4 – Cc: ✅ Correct. This allows others to receive a copy of the email visibly.

Hence, the correct answer is: option 4: Cc

The correct answer is option 2.

Key PointsOption 1: The username and the domain name are separated by @ (at) symbol.

True, The @ (at) symbol is used to separate the user id from the domain name in the e-mail address.

Ex: 

[email protected]

[email protected]

Here user-id is operations and ram.

The domain is Gmail and testbook.

Option 2: E-mail addresses are case-sensitive.

False, Email addresses are not case sensitive. Having letters in all lowercase makes the email address easier to read, but the oversight won't stop your messages from being delivered.

Hence the correct answer is i is true, ii is false.

The correct answer is SMTP, POP.

Key Points

• SMTP is used for sending emails, whereas POP is used for receiving emails.
• SMTP stands for Simple Mail Transfer Protocol.
• POP stands for Post Office Protocol.
• SMTP is a set of communication guidelines that allow the software to transmit electronic mail over the internet.
• Post Office Protocol is an application-layer Internet standard protocol used by e-mail clients to retrieve e-mail from a mail server. 

The correct option is 1).

A valid email address is an address composed of two parts, a username, and a domain name. The prefix appears to the left of the @ symbol. The domain appears to the right of the @ symbol. For example, in the address [email protected], "name" is the email prefix, and "website.com" is the email domain

The 2 parts of an Email Address are:

Username - The first part of an email address is the username.
Domain - The last part of an email address is the domain, which can be broken down into two portions: the mail server and the top-level domain.

Key Points

When you compose an email and hit send, it first goes to the “Outbox” folder before it connects to the mail server and is successfully sent to the recipient. After the messages have been successfully delivered to the recipient, they are being moved to the “Sent” or “Sent Messages folder”. 

If the messages fail to send, they are stuck in the Outbox folder as the communications in and out of the mail server are blocked. Emails stuck in the Outbox are a common issue in email programs, mostly because it fails to connect to the SMTP server. 

Hence the correct answer is outbox, sent.

The correct answer is option 4.

Key Points

• The email header is a code snippet in an HTML email, that contains information about the sender, recipient, email's route to get to the inbox, and various authentication details.

Email Header Characteristics:

• From:
  • sender’s name and email address. 
• To, CC, and BCC:
  • Recipient’s name and email address. 
  • It has To, CC, and BCC.
    • CC stands for carbon copy basically, sending a “carbon copy” of your message to the email addresses you have added to the field.
    • BCC stands for blind carbon copy, allowing you to send a “carbon copy” of your message while keeping the email addresses you have added privately.
• TO field is,
  • according to the rules of email etiquette, meant for the main recipient(s) of your email.
• Date:
  • sent date/time of the email.
• Subject:
  • whatever text the sender entered in the Subject heading before sending.
• Save is not a field in the email Header.
  • Hence the correct answer is I, iii, and iv.

Electronic mail, or email, is the transmission of text-based messages among networked computers. Email is one of the earliest and most basic messaging resources on the Internet and in many ways it still acts as the lowest common denominator for computer communications. Types of email services:

• Free Web-based Email Services: These are the commonly used email accounts accessible through a web browser (such as Internet Explorer, Firefox etc.). They generally use HTTP Protocol for accessing mail. Example: Yahoo Mail, Hotmail, Gmail (whose attachment size limit is 25 MB) offer free web-based email services. These services are run on financial profit from advertisements. Advertisers pay service providers to expose email account holders to advertisement.
• Priced Web-based Email Services: There are also priced web-based email service providers. Many of the free web-based email service providers such as Yahoo! And Hotmail do offer premium account on payment basis. Advantage of utilising such services include more secured transaction of communication; personalised email address; better spam filtration as well as increased storage space. Priced email services are most useful in business-related message exchanges. 
• Private Email Services: Most of the institutions/organisations have their own dedicated mail server and offer mail account for free to their staff and other members of the institution. These accounts exist only till one is member of that institution. For example: [email protected]; [email protected] etc.

Hence, we conclude that email attachment size limit in Gmail is 25 MB.

The correct answer is Paper clip icon.

Key Points

• The paper clip icon next to an email in your inbox indicates a file has been attached to the message, such as a picture, a Word document or a PDF. In other words, the paper clip icon means "see attached." A file that has been appended to an email message in this manner is, appropriately, called an "attachment."

Additional Information

• Emoji icon: Emoticons are punctuation marks, letters, and numbers used to create pictorial icons that generally display an emotion or sentiment.

• Pen icon: Pen emoji is a picture of an ordinary ballpoint Pen of blue or black color. Such pens are commonly used everywhere, where it is necessary to write something down, along with the item represented by  ✏️️ Pencil  emoji.

• The BCC field in the mail is used when you want to send an email to multiple recipients but do not want any of them to know about the other people you have sent them to.
• This prevents the e-mail addresses from being captured by someone in the list who might use them for spamming purposes. 
• CC field means that that person will receive a copy of the email and all other recipients will see their email address.
