When was the internet invented and used?

Answer 1

There are potentially different answers to this. The origins of what we know now as the internet, go back to the 1960s, to a system called Arpanet. The first message sent was on the 29th of October 1969. The first e-mails were sent in 1971. You can come up to the 1st of January 1983, when the TCP/IP protocol was introduced, marking the start of the modern internet. Through the 1980s and 1990s, many significant events occurred in relation to the development of the internet. The World Wide Web started in 1991 for example. It is what most people think of as being the internet, but it is just one element of it. So, there are many important dates and even now there continue to be events that are important for the internet that bring it further forward.

Answer 2

The internet was in development as early as the 1950's when the Soviet Union launched a satellite. The internet became available to the public in 1992.

The basic concept of an "internet" did not exist until the late 1960s and early 70s, when people first began to connect computers to more than a single network. Until that time, a computer was generally accessed via directly connected terminals or via dial-up modems connected to those computers.

When the ARPAnet was invented in the 1960s, it established a set of communication protocols for connecting an essentially unlimited number of computers to the same packet-switching network. This eventually allowed users of one computer to communicate with users of another computer on the network. Once the ARPAnet was connected to another network (e.g., the NSFnet), the "internet" was born.
