- A US Department of Defense agency ordered one of the Research into the creation of the ARPANET in 1999 1962.
- The working group called the Galactic Network was developed and established in 1962 AD, allowing computers to be linked together.
- Leonard Kleinrock published the first A book on how to use and convert Parcels in the construction of the network, in 1964 AD.
- Developed a means of transmitting information from computer to computer in process It was called the switch box, through which information is transmitted, and that was in 1965 AD.
- The first ARPANET conference was held in 1967.
- Two computers were connected to each other, each in a different place, the first was at the University of California, and the second was at Stanford University. At that time, the computer was about the size of a small house, and a login message was sent, ending with the crash of the nascent network, ARPANET, in the year 1969 AD.
- Four computers were connected to the ARPANET network in late 1969.
- In 1971, 23 computers were connected to the ARPANET, and at the same time the first email was sent.
- Norway at the Royal Radar Establishment and England at the University of London were connected to the Internet with only one device each in 1973.
- Network protocol appeared in 1982.
- In 1984, the number of computers connected to ARPANET reached 1,000.
- Swiss programmer Tim Berners-Lee introduced the World Wide Web as we know it today, in 1991 AD, and at the same time HTML web design sites appeared.
- Researchers at the University of Illinois created a sophisticated browser they called Mosaic, called NCSA Mosaic, in 1992.
