Understanding EMAIL | Email versus Gmail | EMAIL PROTOCOLS

“We have no Gmail account but we can Email you.”

“Do you know how journey of Email started? How it works? ”

Sometimes we get confused with these kind of blunders let’s know what exactly email is…

Email – It is basically the method of exchanging messages between people using electronic devices like

personal computer, hand devices through internet.

I think you are not familiar with its history but actually it is quite interesting. First email was sent by computer engineer Ray Tomlinson in 1971, but that email was simply a text message to himself.

First example of email can be found on computer at MIT in a program called “MailBox”, all the way back in 1965.

[Note: Ray Tomlinson developed email by creating ARPANET’s network email system]

Now let’s group some components of Emailing:

  • Email service provider
  • Email application
  • Sender having email address
  • Receiver having email address
  • Outbox of sender
  • Inbox of receiver
  • Internet
  • Attachments

So I know we can’t even notice right. We just send PDF or DOCX through email and can’t even notice its working, its components , how it is made, what is going between it, how safe is it. Now is the time to know now is the time to read-search-ask…

Let me tell you there is nothing much to be worried about Email or Gmail. Simply Gmail is an Email service provider. Let’s explore more.

Protocol Used in Emailing

This is what must be known to them who want to deep dive into working of Email System. As I have taken all consideration that tech newbies also read it :p So first of all let me define protocol.

Protocol is the set of rules or procedure for transmitting data between electronic devices, such as computers.

Here I am going to tell you in brief about SMIP, IMAP and POP protocols and surely with a link for Further reading as per your level of curiosity 🙂



Simple Mail Transfer Protocol (SMTP)

These are the text based commands for forwarding email between Mail Submission Agent (MSA) and Mail Delivery Agent (MDA).
