Hang (computing) is when your computer stops responding and you do not know what to do. This usually happens when your computer is trying to do something and it is taking too long. The computer will stay stuck in this state until you do something to make it work again. To fix it, try rebooting the computer (turning it off and back on again). You can also try running a virus scan to make sure your computer is safe and free of any viruses. If all else fails, you might need to get a new computer.
