Evolution of the IT – An Infographic On Internet History

Internet History – The Precursors

While closely studying the Internet history, we can find that it  has precursors such as the telegraph system, that dates back to the 19th century, more than a century before the digital Internet became widely used in the second half of the 1990s! The telegraph system is the first fully digital communication system. 

The concept of data communication– transmitting data between two different places, connected via some kind of electromagnetic medium, such as radio or an electrical wire – predates the introduction of the first computers. Such communication systems were typically limited to point to point communication between two end devices. Telegraph systems and telex machines can be considered early precursors of this kind of communication.

The Internet today is a widespread information infrastructure, the initial prototype of what is often called the National (or Global or Galactic) Information Infrastructure. Its history is complex and involves many aspects – technological, organizational, and community. And its influence reaches not only to the technical fields of computer communications but throughout society as we move toward increasing use of online tools to accomplish electronic commerce, information acquisition, and community operations.
