He email (also know as e-mail , an English term derived from electronic mail ) is a service that allows the exchange of messages through electronic communication systems. The concept is mainly used to name the system that provides this service via Internet through the protocol SMTP (Simple Mail Transfer Protocol) , but it also allows naming other similar systems that use different technologies. E-mail messages make it possible to send, in addition to text, any type of digital document (images, videos, audios, etc.).
The operation of the email is similar to the post mail . Both allow sending and receiving messages, which reach their destination thanks to the existence of a address . The email also has its own mailboxes: they are servers that temporarily save messages until the recipient reviews them.
The American Ray Tomlinson it was he who incorporated the at (@ ) to the email addresses, with the intention of separating the name of the user and the server where the mailbox is hosted. The explanation is simple: @ , in English, it is pronounced at and means "in" . For example: [email protected] it reads Carlos at server.com (that is, Carlos at server.com ).
In addition to all of the above, we must also disclose the basic structure of any email. Thus, we find the following basic elements:
The recipient. In this box called "To", you can include both one and several addresses of people to whom this email will be sent. In addition, the opportunity is granted that those addresses to be included are not visible to the rest of the people who receive them.
The issue. It is the section where the topic on which the email revolves should appear briefly and briefly.
The message. In this section, of great amplitude, is where you write the message you want to send. So that this text is, aesthetically speaking, as we wish, we offer tools with which to choose the font, alignment, color, hyperlinks and even emoticons.
However, we can not ignore that when sending an email also and in addition to the aforementioned text, and as we have previously stressed, we can incorporate various materials or files. That means we can attach both documents of different types (texts, spreadsheets, database, pdf ...) as photographs and even videos.
Then, who receives said email has different possibilities. Thus, not only can you read it and respond to the issuer of the same but you can also forward it to other recipients, archive it, delete it permanently, mark it, add labels and also catalog it as spam.
The email service is offered under two modalities: known as web mail or webmail , where messages are sent and received through a web page specially designed for it; and service through a email client , which is a program that allows you to manage received messages and write new ones.
