Computer is one of the best inventions of the 20th century. It's hard to believe that one small screen with a keyboard can change everybody's life.
letters would be delivered instantly to the addressee,music can be downloaded in a few seconds,millions of documents can be kept on one device,the quality of photos can be easily improved,video calls can reduce distance between friends and relatives, etc.All this became possible with the appearance of computers. In my opinion this smart device has changed the world. My life has also significantly changed when I first started using the computer. Today I'm literally dependent on it because there are many things computer can do for me. First of all, I try to stay in touch with my friends and English pen pals. In this case I use either e-mails or social networks, such as Facebook or Vkontakte. Social networks are even more convenient. There you can see whether your companion is online or not, you can also follow your friends' news. Messages are delivered instantly, so the answer should be quick. E-mails are also good, but you don't know how soon your friend will check the box, so the answer can take some time.
