Computers have always been a means of saving information which you can use later as a means of feedback when push comes to shove, but as much as a computer can be helpful it can be detrimental as well. Computers are hacked daily stealing the information of users from around the world, but not to worry there are certain precautions built into computers that help to stop this from happening. The second issue you might face with a computer is the breakdown and loss of data, this issue cannot be reversed easily but if given time and energy there are solutions. For example the ROM stores all you’re read only memory which is a sort of backup when your computer breaks down.
