You probably thought that the Internet was created to survive a nuclear attack. Nothing could be further from the truth.
In fact, the true origins of the Internet had no military usage whatsoever. How do I know? I talked to several people who actually created the Internet well, it was called the ARPANET back then. I took the material from those conversations, as well as other primary and secondary historical sources, and prepared a chronological description of how the Internet as we knew it in came into being.
Granted, this is a predominantly US-centric historical account — much work was being done in England and France at the same time, but their influence was beyond the scope of the paper. This history is incredibly valuable. Having a better understanding of the history of the arguably most important technological development since the Gutenberg printing press can, and should, provide a solid foundation for that debate.
Note: This is a peer-reviewed academic paper presented to the American Historical Association in October, It is also text prepared for, but ultimately excised from, my doctoral dissertation. In an effort to preserve the text it has been reprinted here, but artifacts from the original digital file which was heavily corrupted may dissertation on the arpanets development. One of the most used buzzwords in the media today is the Information Superhighway.
Connecting the home to information services, the current administration would have the general public believe that the science fiction of the future is just around the corner. In actuality, that superhighway exists already; it is called the Internet. Every day, millions of messages travel along the hundreds of computer networks that make up the Internet. Few studies have been done concerning the effectiveness of e-mail over the Internet.
Even fewer studies still have examined the culture created by those who use the computer Curtis, ; Metz, ; Reid, But to date, dissertation on the arpanets development, any examinations of how the Internet came to exist have been sparse and, in general, incomplete.
Just how did the ARPANET and later, Internet, come to be? This paper examines that question, attempting to piece together the connections made through history that lead to the foundation of ARPANET. While the ARPANET came into existence in the late s, the events which lead to its development can be traced to the s and the advent of the computer. But, the first concrete idea of resource-sharing — one of the main ideas behind ARPANET — was conceived in World War II.
In addition, dissertation on the arpanets development, the paper will briefly review computer history relevant to the development of the network: from UNIVAC to timesharing to the development of packet switching, and the concept of the ARPANET. The first completely electronic computer was ENIAC, or the Electronic Numerical Integrator and Computer, completed in While the computer was not the very first programmable computer, nor were its inventors — John Mauchley and J.
Presper Eckert, Jr, dissertation on the arpanets development. Just after World War II, Vannevar Bush, then a prominent researcher at M. First, they could not find or read everything in their fields.
Second, what they did read and write usually got lost in the labyrinth of misfiled works because of inflexible indexing systems. Bush suggested a machine to help solve this dilemma. He envisioned a system in which the machine, complete with keyboard, dissertation on the arpanets development, knobs, levers, and displays, would have the ability to store information.
However, this system would not just be limited to indexing and storage; it would also be annotated, with an almost unlimited ability to link documents Press, It later came to be known as the Eckert-Mauchley Computer Co. Unfortunately, the two men were more scientists than businessmen and found themselves on the brink of bankruptcy more than once ACM, ; Augarten, UNIVAC was successful and made quite an impression on the public during the election when it became the first computer to tabulate election results.
The result was electric, literally. UNIVAC remained the most popular machine throughout the s ACM, The effect in the business world was astounding, as the UNIVAC appeared in accounting houses and payroll departments worldwide ACM, Meanwhile, the computer courses offered by the Moore School were attended by several universities, companies and government agencies that had the technical and financial resources to build their own computers.
Before long, the students became the masters, as General Electric, IBM, MIT, and Bell Labs entered the computer arena, with varying degrees of success Augarten, The problem with UNIVAC, and others that immediately followed was that such machines were prohibitively expensive. Companies wanted to own a computer, but faced paying hundreds of thousands of dollars either for their own computer or for renting time on machines owned by other corporations. While cheaper, the latter option left smaller companies waiting for convenient times of use, rather than dissertation on the arpanets development processing.
This cumbersome system compelled anyone seeking use of the machine to hand over to a computer operator a batch of cards punched with holes that coded the program to be run or the problem to be solved. The operator fed the cards into the computer for processing, one batch at a time. As early computers were dissertation on the arpanets development, it was imperative that they not sit idle Press, was the first to make this form of interactivity commonplace, where scientist Jay Forrester created the Whirlwind computer in the s.
The new machine processed real-time telemetry data while being used interactively by an operator at a display-based console Press, Whirlwind was followed by other experimental interactive computers at M. One such visionary was M. scientist John Dissertation on the arpanets development. In extremely large systems, hundreds or even thousands of users can use the system simultaneously without realizing dissertation on the arpanets development others are doing the same.
At peak usage times, however, performance time decreases significantly Phaffenberger, Ultimately, he envisioned time-sharing as a public utility, much like the telephone system is a public utility. The other, and perhaps more influential spokesperson for time-sharing was M.
research psychologist J. In Licklider wrote one of the most influential papers on man-machine symbiosis:. Computing machines can do readily, well, and rapidly many things that are difficult or impossible for computers.
That suggests that a symbiotic cooperation, if successful in integrating the positive characteristics of men and computers, dissertation on the arpanets development, would be of great value Licklider, The idea of time-sharing was to mold the way scientists thought about interactive computing through the s and s.
The technology of real-time based computing became a paradigm of the way computers should be used to share processing ability, but as will be shown later, it nearly killed the ARPANET before it even got started. In the meantime, while people at M. enjoyed interactive computing, the rest of the world was submitting jobs and waiting for output. Time-sharing brought interactive computing to the public, dissertation on the arpanets development, and not too many years later, companies designed for just this purpose began.
In Keydata Corporation leased dumb terminals machines having a display terminal and keyboard, but without computing power to 20 businesses around the metropolitan Boston area and linked those terminals to a UNIVAC mainframe computer in Cambridge.
Ironically, one of the first externally-accessible prototypes for timesharing was created by a man who almost prevented the computer industry from dissertation on the arpanets development off.
By the mid- to lates, time-sharing was the fastest growing element of the computer industry Augarten, These systems were important early steps in the evolution of new ways to link computers into networks.
Dissertation on the arpanets development also entrenched ideas about networking into nearly unmovable ideologies. With the Cold War, the U. government became more interested in computer dissertation on the arpanets development networks. Those networking ideologies interfered with overcoming two major problems that afflicted time-sharing systems: computer incompatibility and unreliability of the data transmission method.
In general, different machines have different operating systems, and these systems are unintelligible to each other:. For example, one computer may express letters and numbers in a different code from another. Or one machine may transmit data at a rate that another is unprepared to accept.
Computer protocols, then, described precisely the form that data must take before it can pass through a network, the rate at which computers may transmit information, and the method by which data is checked for dissertation on the arpanets development that might occur en route.
In theory, protocols should have made communication easier between host computers. But in practice such was not the case, dissertation on the arpanets development.
With only one host computer in charge, no questions of authority or compatibility existed: the host was the authority. Consequently, dissertation on the arpanets development, the s were marked with the need to provide a standardized code for computer communications systems. Each computer maker had its own way of encoding data within its machines. In essence, ASCII was one of the first computer communication network protocols.
Once a common method of coding data for communications was established, another standard was needed to specify exactly how the encoded information would be transmitted by modem over a telephone wire. Telephone lines and computer circuits were extremely fragile and intolerant of environmental deviations, such as power outages and thunderstorms.
With these problems in mind, a coalition of interested groups joined to lay down the procedures for the link between computer and modem. This group, which was formed by representatives of the Electronics Industries Association, various manufacturers of communications equipment, and Bell laboratories, produced such a protocol in Even with a standardized code for representing data and a protocol for electronic communications, the Advanced Research Projects Agency ARPA started an ambitious effort to address these protocol issues as well.
The obvious solution for the networking problem was the time-sharing possibilities emerging at the time. In fact, ARPA was a major funder of several time-sharing experiments. This was no accident: Licklider was the first head of the Information Processing Techniques Office at ARPA Press, Two main problems existed with time-sharing, however. First, even though timesharing enabled interactive computing, the systems were limited to command-oriented interfaces, instead of more user-friendly WYSIWYG [What-you-see-is-what-you-get] displays Press, Second, time-sharing was not the same thing as a multi-processing computer Augarten, Although time-shared computers could support many terminals and perform many tasks at the same time, it could not run different programs simultaneously.
Combine these with the unreliability of the telephone lines, and the need for a different system was obvious. ARPA assigned Lawrence G. Roberts the task of solving the networking problem. Roberts earned his Ph.
