In computing, a clone is a hardware or software system that is designed to mimic another system. Compatibility with the original system is usually the explicit purpose of cloning hardware or low-level software such as operating systems (e.g. AROS and MorphOS are intended to be compatible with AmigaOS). Application software can be cloned simply by providing similar functionality (all word processors have the same basic purpose), but may also be designed to support specific file formats (e.g., OpenOffice.org is intended to supplant Microsoft Office).
