What is e -mail?

Email, sometimes written as an e-mail, is simply a shortened form of "e-mail", a system for receiving, sending and storing electronic messages. It has gained almost universal popularity around the world with the spread of the Internet. In many cases, e -mail has become a preferred method for personal and business communication.

How is used

Messages sent by e -mail usually reach the recipient's account in seconds. Often include more than just text; Images and many types of formatted documents are now easily included as attached files. In addition, it is no longer necessary to sit in front of the PC for sending or receiving the e -mail. Many mobile devices, such as tablet computers and smartphones, allow you to manage correspondence on the go.

protocols

users receive and send messages using standardized protocols that allow e -mails trouble -free travel between computers running different software and across different types of serversthe nets. Simple message transmission protocol (SMTP) allows actual sending and receiving messages. Other protocols, including the postal authorities (POP) and IMAP protocol) and the IMAP protocol) allow users to load and store messages over time.

client software

At the beginning, a program called "Client Software" was necessary for manipulation. There are many different e -mail applications, some of which cost money while others are free; Some Internet providers even include this into service. Client software is still used to this day, but there is another flexible method that has recently become more popular.

Webmail

In addition to accessing an electronic post office via client software, webmail is another popular option. Most service providers offer it a joker advantage where the user has access to his mailThe box over the Internet, from any computer or other device connected to the site. Some e -mail services are specially designed to use World Wide Web as its primary interface. These sites, called "portals", have become very popular because they usually offer individuals a chance to open a free e -mail account, along with access to search engines, messages, calendar and many other sources from one place.

History

Although there is some degree of uncertainty when e -mail has been invented, the father of the modern version is generally considered an American, Ray Tomlinson. Before Tomlinson, users could send messages to each other, but only when they were connected to the same computer. Even after computers were connected, messages could not be focused on a particular individual. Tomlinson invented a way to reach out to some users and was credited as one of the most important communication inventions in the 20th century.

Tomlinson's idea waso identify the user name and the computer in which it was placed. As a result, the basic formula for solving the e -mail was the username@userComputer. This standard has not changed much over the years, except for a user computer, it is now commonly replaced by the name of the service provider.

Personal Data Protection

from a legal point of view is generally considered a private form of communication, almost the same as a phone call or even a manually written letter; Specifics will vary from one country to another, but usually is an illegal approach, read or publish other persons without permission. However, it is important to understand that it is relatively easy for hackers to capture e -mail. In addition, many companies require their employees to sign an employer's permission agreement to monitor all reports sent or received at the company's e -mail addresses.

Another problem of personal data protection is that each electronic message becomes more orLess permanent communication record. Selecting a message for erase will remove it from a visible queue on the user's account, but a person should never assume that the message is indeed gone; Deleting e -mails are notoriously easily resurrected. Although the sender uses specialized software to thoroughly smooth out all tracks of his computer, copies of E -mail are likely to still exist at the end of the receiver, as well as many servers he has traveled to. As a result, it is not wise to send sensitive information using this method without carefully considering the possibility that the outside side could catch it. Since E -Maily is automatically stamped with time and date, these records are often summoned by courts to determine the time line for a particular chain of event.

influence

the effect of e -mail cannot be overestimated. The United Starna Postal Service EC notes that it processes 485 million pieces of mail a day. For comparison, 39.6 billion e -mails are sent every day in the United States. By others withHunting, e -mail providers process more than 81 times the volume of the largest postal system in the world. It is perhaps just like revealing to what extent Electronic Mail has influenced the use of traditional "worm mail", as is often referred to today. The US Postal Service, together with many other world postal services, has seen a dramatic decline in the volume and income that began in the later half of the 90s and which have continued since then; This is partly because so much personal and business correspondence is now delivered by e -mail.
