Copyright in computer refers to the legal protection of machine-readable software. It is a type of intellectual property that protects original works of authorship, including computer programs. Copyright law prohibits not only literal copying but also copying of "nonliteral elements," such as a programs structure, sequence, and organization. Copyright attaches only to original works, and a work is considered "created" when it is fixed in a "tangible medium of expression" for the first time. The graphics, sounds, and appearance of a computer program may also be protected as an audiovisual work, and a program can infringe even if no code was copied.

In summary, copyright in computer is a legal term that describes ownership and control of the rights to the use and distribution of certain works of creative expression, including computer programs. It protects original works of authorship and prohibits unauthorized duplication or use.
