The computer A+ ;)

Answer 2

The internet was made possible by a combination of things. Obviously, all the inventions leading up to modern computers: things like vacuum tubes, vacuum tube arrays for memory, the integrated circuit. Screens, computing algorithms. GUIs, or graphical user interfaces (using pictures instead of text to use a computer) probably helped. In addition, the telegraph, then the phone, then television all helped. The idea of connecting computers, which originated with large companies like IBM, at universities, and among certain portions of higher levels of governments set the seed idea. Then all that was needed was a universal language for computers to talk, which came in the Internet protocol suite, or TCP/IP system. That was the early 80s. From there it just slowly built up as computers got stronger, and people could do more with them. Information was easier to store more of, and the internet grew along with that limit. Now, in a few hours, you can download an entire multi-gigabyte video game, and that is with a crappy internet connection. When the internet was starting out, a gigabyte was to them more amazing than a terabyte is to us now.
