Email

✨ The electronic letter

Email, short for electronic mail, is a digital communication system that allows people to send and receive messages through the internet. An email can contain text, images, documents, and other files, making it a practical way to exchange information quickly around the world.

To send and receive emails, users need an email address provided by a service and usually access their messages through a website, application, or email program. Since its development in the early days of the internet, email has become one of the most widely used forms of digital communication.

It is used by individuals, businesses, schools, and organizations for personal conversations, professional exchanges, and sharing important documents. Email systems use servers that store and transfer messages between users, allowing communication even when the sender and receiver are not connected at the same time.

However, email also requires caution because it can be targeted by spam, phishing attempts, and malicious attachments. Using strong passwords and being careful with unknown messages helps keep email communication safer.

💡 Did you know?

Do you know what the content of the very first email was? Ray Tomlinson, its inventor, simply wrote 'QWERTYUIOP'. These are the first letters at the top left of a keyboard! He was testing his machine to see if a message could travel between two computers. He did not imagine that this would become the most used communication tool in the world.

Why is the @ sign used? In the Middle Ages, the 'at' symbol was already used by merchants to save time by writing 'at the rate of.' Ray Tomlinson chose this symbol in 1971 because it was never used in family names. It was the perfect way to say: this user is 'at' this computer domain.

The word 'SPAM,' which refers to advertising emails that no one likes, comes from a Monty Python comedy sketch! In this sketch, a waitress offers a menu where the word 'Spam' (a brand of canned meat) appears so many times that it becomes annoying. Engineers found that this perfectly resembled those emails that repeat incessantly.
