The invention of the Internet
Possibly the greatest technological invention of our time. The Internet has had a huge impact on science from connecting scientists across the globe and allowing them to share information and research more easily, to providing scientific resources and papers to more people than ever.
What most of us think of as the Internet is really just the pretty face of the operation—browser windows, websites, URLs, and search bars. But the real Internet, the brain behind the information superhighway, is an intricate set of protocols and rules that someone had to develop before we could get to the World Wide Web. Computer scientists Vinton Cerf and Bob Kahn are credited with inventing the Internet communication protocols we use today and the system referred to as the Internet.
Before the current iteration of the Internet, long-distance networking between computers was first accomplished in a 1969 experiment by two research teams at UCLA and Stanford. Though the system crashed during the initial attempt to log in to the neighboring computer, the researchers, led by Leonard Kleinrock, succeeded in creating the first two-node network. The experiment was also the first test of “packet switching,” a method of transferring data between two computer systems. Packet switching separates information into smaller “packets” of data that are then transported across multiple different channels and reassembled at their destination. The packet-switching method is still the basis of data transfer today. When you send an email to someone, instead of needing to establish a connection with the recipient before you send, the email is broken up into packets and can be read once all of the packets have been reassembled and received.

Hello, Andrew!
Thank you for your letter. It was great to hear from you again.
In your letter you ask me about English language. In my opinion, the most difficult thing in English is grammar. It is really hard for me. To improve my English outside I download special app, where I can chatting with people, who live in England. I think the best way to learn a foreign language is to speak with a native-speaker. They know them language as good, as we know Russian. So it is really very useful.
Sorry, I have to go now, because I have a lot of homework.
White back soon!
Love,
