The desire to communicate is among the most primitive living creatures, and particularly in humans. Since time immemorial, the means and techniques of communication have worked on and refined. The beginning of man communicated orally or in writing. They used pictorial representations old still visible on the walls of caves. If there was a physical distance between the parties who want to communicate, the messages were transported by a courier. Early 'jungle drum "and" smoke signal ", transmissions were proof of the first form of distance communication where a messenger was not physically sent to the desired destination. Send stands for "electronic mail". By this definition, the first e-mails were sent in the past century by telegraphic transfer and Morse code transmissions. Business widely used for the telex network communication anywhere in the world since the mid 1920's through the mid 1980's. A telex to connect and communicate with any other teletype machine anywhere in the world, independent of the telephone network. Security has been so tight that the telex has made identifying the machines by hand. However, to send telex messages, a dedicated telex line should be installed and telex were indicted based on the amount of data transmitted. This requirement for a dedicated line, the communication by telex expensive. Moreover, in order to use telex, a telex terminal is usually required training of operators who needed to operate it. Surprisingly, the telex is still popular around the world, despite the growth of the Internet. Mainframe and miniframe computers are very popular with many major companies in the 1960's and 1970's. They exchanged e-mails on these computers. Users (in this case, employees of the company) from their computers (terminals) can send messages to each other. Gradually, corporate systems, known as the host, began to be connected to the branches. Now, employees can communicate with their counterparts by e-mail on a global scale. APRANET was developed by the US Department of Defense, as part of his research on computer networks during this period. Messaging Network has been developed for the APRANET, and has now evolved into the email technology in its current form. The first APRANET electronic message was sent in 1971. The late 1970 and 1980, has seen astronomical growth in the personal computer market with the entry of Apple and IBM. This led to the creation of new messaging technologies. Owners' dial 'systems such as MCI Mail, Telecom Gold and AppleLink were among them. This means that for two people to communicate by e-mail on these systems, the two had to be subscribers. Most of these systems are eventually become obsolete because they were not reliable. It should be noted here that the e-mails were sent and received by thousands of users of personal computers using 'dial' systems before the Internet became available for use by everyone. Another development is proceeding in parallel with the above-development "of the LAN-based electronic messaging systems within companies, linking personal computers used by their staff to the mainframe . These systems are easier to use and more functional. They even allowed to send attachments with e-mails. Gradually, the use of the Internet for access to information is gaining immense popularity. Over time, as more and more people have access to the Internet, email applications evolved owners messaging systems within corporate networks "Intranets," which can be described as mini private Internets. Therefore, we can say that "electronic mail" is not in itself a new phenomenon. What is new is that it is more easily available globally, is not expensive and much easier to use. |
