"These categories should be viewed broadly. For example, computer programs and most "compilations" may be registered as "literary works""
Compiling the source code creates either a "derivative work" or a "copy", depending on the specifics of the compilation process. Modifying the code creates a "derivative work". Creating backups as a "copy". Letting other people connect to it is a public "performance" or "display". All of these are exclusive rights under copyright law.
