Write about the history of Internet

The history of the Internet begins with the development of electronic computers in the 1950s. Initial concepts of wide area networking originated in several computer science laboratories in the United States, United Kingdom, and France. The US Department of Defense awarded contracts as early as the 1960s, including for the development of the ARPANET project, directed by Robert Taylor and managed by Lawrence Roberts. The first message was sent over the ARPANET in 1969 from computer science Professor Leonard Kleinrock's laboratory at University of California, Los Angeles (UCLA) to the second network node at Stanford Research Institute(SRI).
Packet switching networks such as the NPL network, ARPANET, Tymnet, Merit Network, CYCLADES, and Telenet, were developed in the late 1960s and early 1970s using a variety of communications protocols. Donald Davies first demonstrated packet switching in 1967 at the National Physics Laboratory(NPL) in the UK, which became a testbed for UK research for almost two decades. The ARPANET project led to the development of protocols for internetworking, in which multiple separate networks could be joined into a network of networks.
The Internet protocol suite (TCP/IP) was developed by Robert E. Kahn and Vint Cerf in the 1970s and became the standard networking protocol on the ARPANET, incorporating concepts from the French CYCLADES project directed by Louis Pouzin. In the early 1980s the NSF funded the establishment for national supercomputing centers at several universities, and provided interconnectivity in 1986 with the NSFNETproject, which also created network access to the supercomputer sites in the United States from research and education organizations. Commercial Internet service providers (ISPs) began to emerge in the very late 1980s. The ARPANET was decommissioned in 1990. Limited private connections to parts of the Internet by officially commercial entities emerged in several American cities by late 1989 and 1990, and the NSFNET was decommissioned in 1995, removing the last restrictions on the use of the Internet to carry commercial traffic.
In the 1980s, research at CERN in Switzerland by British computer scientist Tim Berners-Leeresulted in the World Wide Web, linking hypertext documents into an information system, accessible from any node on the network. Since the mid-1990s, the Internet has had a revolutionary impact on culture, commerce, and technology, including the rise of near-instant communication by electronic mail, instant messaging, voice over Internet Protocol (VoIP) telephone calls, two-way interactive video calls, and the World Wide Web with its discussion forums, blogs, social networking, and online shopping sites. The research and education community continues to develop and use advanced networks such as JANET in the United Kingdom and Internet2 in the United States. Increasing amounts of data are transmitted at higher and higher speeds over fiber optic networks operating at 1-Gbit/s, 10-Gbit/s, or more. The Internet's takeover of the global communication landscape was almost instant in historical terms: it only communicated 1% of the information flowing through two-way telecommunications networks in the year 1993, already 51% by 2000, and more than 97% of the telecommunicated information by 2007. Today the Internet continues to grow, driven by ever greater amounts of online information, commerce, entertainment, and social networking.

Internet:
Internet - Internet has now became the basic need of Human life. After lots of inventions and discoveries, Humans started to use internet. And, today almost 3.5 Billion people uses internet among the 8 Billion people. As the use of internet is growing very rapidly, we can't predict the future of the internet. We can't predict it's future speed, Latency and time difference.
Today, The mail service is the most used service all over the internet. About 20 million Mails are sent on the internet in a single minute. That's a very huge number. Mail services and online chatting services had become cheap as compared to mobile operators messaging services. Lot of things can be done using the internet. We can search for anything on the internet, we can communicate with the people from different countries, friends, relatives and parents.
Internet has taken the major role in the human life. Everything can be done today using internet. We can share our views, posts and articles publicly. We can navigate to maps, with the help of which, we can find our destinations and locations in the new cities. We can also explore the outer world and it's different wonders using special services. Internet can be today used for applying for exams, train tickets, Airplane tickets, watching TV and shows online and everything.

Mobile: In 1900's, the basic need of Human beings were "Clothes, Food, Home". In 1990's decade, this needs were increased to electricity. And today in 2020, the Mobile phone is one of the basic need of human beings. It is because, No one can today spend a day without a mobile phone. According to a survey, Almost every mobile phone user spend 4 hours in a day using smartphone.
Mobile phones are today generally used for communication, chats, Information and technology, World's exploration. Mobile phone is really very helpful and important thing until we don't overuse it. Most of the people use their mobile phones just for Photography, Playing games, Watching comedy videos and all unnecessary things.
Every year, Tons of smartphones are launched all over the world. Every year, Compact phones are getting better and better by the years. Due to various new features, Customers are attracting towards the mobile phones and this is how, The tech companies are earning.
Mobile phones can be used for communication, giving online examinations, online shopping, searching and finding information, Exploring the world, Sharing our views with the people using social media, Advertising our products and many more other things.
There are some disadvantages of using mobile phones too. Due to long time in contact with the mobile screen, we can have the problems relates to our eyes, If we use mobile phones continuously for longer time, then it may affect our neck and our vertebral column can have different problems, Some people can also get affected by the diseases like Brain tumor.
