Software piracy is the unauthorized copying or distribution of copyrighted software. This can be done by copying, downloading, sharing, selling, or installing multiple copies onto personal or work computers. What a lot of people don't realize or don't think about is that when you purchase software, you are actually purchasing a license to use it, not the actual software. That license is what tells you how many times you can install the software, so it's important to read it. If you make more copies of the software than the license permits, you are pirating.
