Whether you ” re an average teenager wanting to keep in touch with friends after school, or a business person needing a low cost but effective way to keep work related material local and secret, chances are you use E-Mail or Instant Messaging services. For communication purposes in this high tech lifestyle that exists today, these systems are used only with the basic understanding needed to run these devices. You are about to learn how these systems came to be and the in depth understanding needed to make them work. To start with, you must know that they require a system of computers connected to a LAN (Local Area Network) server. The most commonly used and largest LAN server in the world is the Internet. Since the internet hosts the majority of all IM (Instant Messaging) and E-Mail servers, then you must know the beginnings of it.
The Internet’s precursor was the ARPANET. The ARPANET was a large wide-area network created by the United States Defense Advanced Research project Agency (ARPA).
Established in 1969 ARPANET served as a test-bed for new networking technologies, linking many universities and research centers. The first two nodes that formed the ARPANET were UCLA and the Stanford Research Institute, followed by the University of Utah. Because of his unique expertise in data networking Len Kleinrock would use the technology which by then had come to be known as “packet switching.” When TCP/IP (Transmission Control Protocol / Internet Protocol) was adopted by the ARPANET as its connection for the networks, the Internet was born. The first email message was sent by Len Kleinrock in 1973.

He used the Resource-Sharing Executive program (RSEXEC) to send a message to a man in London that he forgot his razor in his room and to retrieve it while at the international meeting for government funding projects like the ARPANET from other countries. To do so he first had to run the RSEXEC program in his home in Los Angeles and then had to think of a person on the network at 3 A. M. When he did, he put the “where so-and-so” command in and connected his computer to the other so the TALK command would be enabled.
RSEXEC opened a split screen window, one to write messages and the other to read. As time passed, this process of using a resource sharing program as a message sending system became widely used. Later a man named Ray Tomlinson created a message mailing and message reading program. To send messages, you’d use the program “SND MSG”; to receive / read messages, you’d use the program “READ MAIL.” Even though Tomlinson was famous for his invention of this two programs his main claim to fame was a decision he made while writing these programs.
He needed a way to separate the e-mail address from the username. He wanted a character that would not be used in the username. While looking at the standard keyboard used by most ARPANET users, he chose the @ symbol. Ray did not intend the program to be used on the ARPANET, like most mailbox programs it was intended to be used on local time-sharing systems. It was designed to handle mail locally and not over wide distances. Stephen Lukasik’s, when appointed as head of the agency that ran the ARPANET, first action was to receive an e-mail address and access to the ARPANET on his “portable” computer.
He was also one of the very first business men who promoted the idea of using mailbox systems like Tomlinson’s for work related communication. During meetings he would use his computer to dial-up his mail to view. Many workers saw this as a way to get the boss’ approval on an idea quickly. But by 1973 three quarters of all traffic on ARPANET was e-mail. With the e-mail flow was so large and Lukasik being the boss, his e-mail was piling up in his in-box. The day after talking to Larry Roberts about his e-mail situation, Roberts came in with a bit of code that could show a menu of messages, file messages, or delete them.
The Essay on Netiquette Mail Message Dries
As we enter the age of computer technology, more and more people are relying on the computer for communication. The main medium of computer communication is e-mail. When using e-mail there are some basic unwritten rules that one should follow. E-mail protocol, better known as netiquette, is the list of rules that are generally followed. None of these have officially been written down in a book, ...
This program was the very first e-mail manager. Many people on the ARPANET loved Roberts program “RD” for READ. Soon people began to make little tweaks to it and operating systems where flooded with programs such as NRD, WRD, BANANA RD, HG, and MAIL SYS. One of the later complications with e-mail were the header wars. The header wars where based on human disagreement on how much information was to be displayed at the head of a message. Of course, many people displayed information in their header that other people would say as too much and considered it to be out of balance with the message.
The problem was solved when a regulation was set for the header to only show the ‘date’ and ‘from’ categories. As time past, more people became relaxed on what they said over e-mail and there began to come messages about anti-war including forms of anarchy and disagreements over Nixon’s impeachment. As e-mail systems became large and more complex, separate computers called servers where dedicated to running new e-mail programs some examples would be SMTP, POP 3, IMAP. By 1976 the number of e-mail messages sent compared to the amount of first class mail handled by the Postal Service was still a child compared the Postal Service, but the increasing numbers of e-mail transactions were not going unnoticed. These increasing numbers caused Arthur D. Little to include in his report for the White House Office of Telecommunications Policy that within a few years thirty percent of all first class mail would be sent via e-mail.
To compete with e-mail, the Postal Service proposed that they would convert messages from electronic information to a paper that would be delivered by a mailman. This system seemed very flawed to the Msg Group. They saw that even though the information was sent first over e-mail then to paper it still depended on the foot power of the mailman to deliver it as opposed to email which could be sent and received with seconds. Stefferud thought that a desktop computer was the perfect mailbox. So he predicted that because the Postal Service would always depend on foot power, e-mail would bypass them completely. In our world, sometimes even the rapid response of e-mail is not enough.
The Essay on Understand the Use of Electronic Message Systems
1.3 Explain the purpose of keeping an electronic message system up to date. The purpose of keeping an electronic message system up to date is that we know which messages we dealt with also to avoid miscommunication. It also allows you to have more clear view at other messages. For example every day when I’m coming to work I’m checking my emails and as soon as I reply or finish reading and it’s not ...
You have no way of knowing if the person you are sending an e-mail to is online at that moment in time or not. Also, if you are sending multiple e-mails back and forth with the same person, you normally have to click through a few steps to read, reply and send the e-mail. Instant messaging also allows you to maintain a list of people that you wish to communicate with something similar to an address book. You can send messages to any of the people in your list, often called a buddy list or contact list, as long as that person is online. Sending a message opens up a small window where you and your friend can type in messages that both of you can see.
This has helped Instant Messaging (IM) gain popularity. Instant Messaging was invented by four young Israelis -Yair Goldfinger, Arik Vari, Sef i Vigiser, and Amn on Amir. These four men created a company called Mirabilis. They wanted to find a way to take all the people connected to the internet and have a way to allow the users to find each other on the web. They also wanted them to be able to create peer-to-peer channels easily.
They called their technology ICQ short for SEEK YOU. Within six months of its release in 1996, Mirabilis was carrying over eight hundred and fifty thousand users. By the end of 1997, Mirabilis was able to hold a hundred thousand users active at one time, this made it the largest internet communications network. Since the success of ICQ was so great that in June of 1998 AOL bought the technology for two hundred and eighty seven million dollars.
Microsoft and Yahoo also came out with their own versions as well. Since AOL controls the majority of IM systems, it will not allow the software the capability to communicate with other IM systems. Other companies have taken a different approach rather than wait for an agreed-upon standard. Jabber is one company that has created a client program capable of communicating with various IM systems. Instant Messaging works by using a piece software called a CLIENT.

The CLIENT is normally a software the is in the server and / or maybe needed in the user to machine for proper use. The client communicates with an ICQ server whenever the user’s online and the client is running. The Internet Engineering Task Force (IETF) is currently developing a standard protocol for instant messaging, this protocol is know as the Instant Messaging and Presence Protocol. As time has passed and technologies have improved more and more little things tend to replace the uses of what was once a great and commonly used services. So who is not to say that one day the usage of e-mail services will gradually be wilted away by some unheard of system that may become just as big.
