POP Full Form – What Is POP, Definition, Meaning, Uses

POP Full Form – What Is POP, Definition, Meaning, and Uses will be discussed here. At one point or another, you may have used “client” software (such as Outlook) to access and handle your email. These email clients may require the Post Office Protocol (or POP) to be configured to receive an email and SMTP to send an email before the message can be retrieved from the server. So, by reading this post today, you will better understand what POP is and how it operates.

POP Full Form

Since its inception in 1984, the Post Office Protocol (new version. The Post Office Protocol (POP3) is an Internet standard protocol for receiving email from a remote mail server via a TCP/IP connection by local email software clients. It has become one of the most widely used protocols, with practically every email client supporting it. Its appeal stems from the ease with which it can be configured, operated, and maintained.

POP3 is also used by email servers operated by Internet service providers to receive and store emails for their users. These Subscribers will check their mailboxes on remote servers and download any emails addressed to them from time to time using email client software.

Emails usually are erased from the server once an email client downloads them. However, some email applications allow users to decide whether the email should be copied or retained on the server for some time, such as up to 14 days.

Secure Sockets Layer (SSL) or Transport Layer Security (TLS) can be employed. If a POP3 server supports encrypted communication, users can connect using the STLS command after the protocol initiation phase or POP3S, which connects to the server on TCP port 995. To connect to POP3 servers, most email clients use the well-known TCP port 110.

What apps make use of POP Full Form 

POP3 is compatible with any email program set to host the protocol because of its primary way of storing and receiving email. Popular email systems like Outlook Express natively support POP3. POP3 is utilized by backup and synchronization tools in addition to simple programs that use it to retrieve mail.

What is POP’s background?

The Internet Engineering Task Force published the initial version of the Post Office Protocol as RFC 918 in Request for Comments in 1984. As a result, engineers realized they needed to create a simple and quick method of receiving emails from the server. Instead of accessing the mailbox online, he realized the benefit of reading the email offline.

RFC 937 established version 2 of the Post Office Protocol in 1985, which was updated by version 3 in 1988 with the publication of RFC 1081. POP3 was changed multiple times over the next ten years until being published as 1996 RFC 1939, the current standard.

Despite many upgrades and modifications, POP3’s creators have retained the essential premise of a simple protocol with a three-stage procedure between client and server during mail retrieval. POP3 is one of the most common mail retrieval systems today due to its simplicity.

What is POP, and how does it work?

When you check for a new email, the client will connect to the POP3 server. The email client then gives the server its username and password for authentication. When the client is connected, it uses a sequence of text-based commands to obtain all email messages. It then saves the downloaded messages on your local system as new emails, deletes the server’s copies, and disconnects from the server.

Email is removed from the server by default after it is retrieved. As a result, the emails are stored on your computer, and the email client cannot access them from any other computer. This can be accomplished by adjusting the email client’s settings to save a copy of the email on the server.

Because emails and attachments are downloaded and destroyed at the server end each time the email client checks for new mail, POP frees up mailbox space on the server. One disadvantage of POP3 mail accounts is that it is difficult to export messages if you change email programs or computers.

What is the difference between POP and IMAP?

POP and IMAP (Internet Message Access Protocol) are two similar email retrieval protocols. On the other hand, POP is outdated and only defines basic commands for retrieving emails; it allows synchronization across IMAP devices and internet access.

When using POP, messages are saved and managed locally on a computer or device. As a result, POP is more straightforward to implement and more trustworthy and stable in general.

What are the benefits of using POP?

  • Emails are downloaded to the desktops of users. Users can read their messages even if they are not connected to the internet.
  • Because the attachments have already been downloaded, opening them is simple and quick.
  • Less server storage space is required because all email is kept locally on the PC.
  • The size of your hard disk limits the amount of email storage you can have.
  • Immensely popular and straightforward to set up and use.

What are the drawbacks of using the POP Full Form? 

  • Email cannot be accessed from other computers (unless configured to do so).
  • It cannot be easy to export a local mail folder to another email client or a real PC.
  • Email folders can become corrupt, resulting in the loss of whole mailboxes all at once.
  • Email attachments may include viruses that might harm your computer if you open them and your antivirus software fails to detect them.


Q1. How does POP work?

It is frequently used to build and hold ornamental plasterwork pieces on cornices and ceilings. Even though many contemporary orthopedic casts are composed of fiberglass or thermoplastics, plaster is still used in medicine to create forms that keep broken bones immobilized while they recover.

Q2. What is POP’s complete chemical form in cement?

Gypsum is converted into the fine, white powder known as plaster of Paris (POP) by heating the gypsum mineral. Gypsum loses water when heated to roughly 150 °C, creating the application of Paris powder.

Q3. What does POP at home’s real name mean?

Plaster of Paris, also known as POP, is a quick-setting plaster comprised of white powder that hardens after being mixed with water. POP can be used to create creative trims and artificial ceilings for interior decorating.
