You can use a computer for so many things that you need to do. For example, you can use a computer to make different files and documents. I normally use the computer in order to do work. Without a computer, I will not be able to work on anything.
There are instances when I also use the computer in order to watch videos and to edit some images that are related to the things that I will post. People will always have different uses for their computers but the ones I mentioned are just a few of the things that I do on a daily basis.
