What is copyright? Copy right is the branch of the law, which protects works from unauthorized use by other people. It allows creators to benefit financially from their works and to retain some control over how they are subsequently used. The original creator may own copyright or it may be assigned to another person. Bodies such as corporations will usually own the copy right in works created by their employees. The categories of work that copyright protects include literary, dramatic, musical or artistic works. “Literary” includes all written materials from novels to lyrics to computer programs. Copyright also protects sound recording, films, television and sound broadcasting and books. The owner of the copyright in a work has the right to publish, produce, broadcast or to perform in public. Computer Software and copy right law. You should be aware that under United States Copy right Law you have the right to make archival backups of your computer software, even if your license agreement states that you no make copies for any reason.

A good application software package may take many programmers years to develop and can represent an investment of millions of dollars. This investment can only be recovered by selling the software to paying customers. When software is given away free, it makes it difficult for software creators to stay in business. This makes it improper to make copies of software and sell it. All of the above is arguments again pirating software, not against copying it. The fact is that to say in business, you must have backups. Whenever the issue of copying comes into court, there is no difficulty in obtaining computer professional to say that backup copies are essential. No case has come so far in which pirates have been successfully.
