Computers were invented not so long time ago. Even one decade ago, we didn't use this technology as much as we use it today. Nowadays, computers play a massive role in our lives. Because of that, there are some people who think being able to use a computer, is required to be included in the other skills. We really use that piece of technology for every single thing. Even a smartphone that is in every modern person's pocket, is a small computer. We consume content, set an alarm to wake up, calculate and last but not least, we study by using computers. It is a replacement for so many things. It makes our lives way more easier.
