Cross section of history
The first network nodes that make up the Internet were created in 1964 by order of the US Department of Defense. In 1983, the Internet took on almost the form we know it today. The Internet became known to the public after 1989, and its huge expansion came only after computers became a common part of workplaces and households. Today, the Internet is an endless source of information, entertainment, online communication, etc. An internet shop (e-Shop) was created, which is more popular with consumers from year to year. The customer chooses the goods in the warmth of his home, pays by Internet Banking or another form of electronic banking (which is used by most of us) and the courier delivers it to his door. Companies, organizations and individuals are becoming more and more visible on the Internet. Even very small companies have their own website.
Thanks to the Internet, discussion forums and blogs have been created, which are among the most visited websites worldwide (Facebook, Twitter, Badoo, Pokec, etc.). Colleagues and friends can be sent any computer file as an attachment. It is possible to upload the file to a website or FTP server so that others can easily download it. In today’s world, a user can have their Notebook connected to the Internet anywhere without the need for a landline. The same is true of most cell phones. While since 1995 the Internet has been dominated by applications and services, where a server was needed to transfer data between clients (their PCs), now the government is taken over by P2P (Peer-to-peer) networks, where it is already a matter of direct communication. between PCs without a server. Around 2025 they will be replaced by video and after 2025 video-communication services such as online education, work, conferences or healthcare. According to the creator of the World Wide Web, Teem Berners-Lee,the continuation of the Internet should be a network that will anticipate the wishes of users and will have functions unimaginable for us today, in short, let us be surprised by what the future will bring us.
