The Internet
The Internet is a worldwide system of computer networks, or a collection of all the world's computers that are linked together.
The Internet enables global communication. With the Internet we can quickly move information from one place to another. Nowadays people can do business online, send letters, create web-sites, chat with friends, sell and buy lots of things, watch videos, share recipes, listen to music, learn languages... In short, the Internet saves our time and effort and makes the world much more efficient.
However, we should always be aware of its dangers. People, and especially children, can face threats like cyberbullying and inappropriate content. Besides, using social networks or playing online games can be addictive.
As for me, I use the Internet to study. I look for information needed, do tests, watch educational videos, read books online. I also listen to music, watch films and post to social media.
It is hard for me to imagine my life without the Internet, and I am glad that it was invented, but I am sure that we all should always remember about its good and bad aspects.
