a bundle of related programs that are ready for you to install
a retailing concept that bundles the right-to-use license with the media and documentation in a single box, usually shrink-wrapped for security
A program and its associated files, archived and compressed into a single file along with any necessary scripts or information to aid in managing the installation, upgrade, and removal of those files.
A suite of programs, purchased at considerable cost from a third-party, that on delivery supplies most of the functionality desired by the users, and which must therefore be extensively (and expensively) modified to ensure that it no longer does.
A computer application program delivered to the user in a complete and ready-to-run form, including all necessary utility programs and documentation.
A computer program designed to perform specific analysis and design operations or generate results in a particular format.
A software package is a bundle of one or several files that either are necessary for the execution of a computer program, or add features for a program already installed on the computer or network of computers. Software packages can either be in a standardised package format to be installed by a program that is integrated with the operating system, or be a self-sufficient installer. This latter approach is commonly used by distributors of commercial, closed-source software, particularly for installation on Microsoft Windows, and less often for Mac OS X, whereas more traditional and particularly free Unix-like operating systems favour the use of standardised formats that are extensions of file archive formats.
