Software is the "What" of the personal computer. Software in short establishes what we do and experience using the computer. Software goes by many names, "applications", "programs", "utilities", and many more specific names, which are really names of specific applications, like "Microsoft Word", or "Internet Explorer".

Software is commonly defined partly by what it is not (it is not the operating system). In truth the operating system is actualy made up of many individual software programs which have evolved into a larger interrelated system.

Software then is a collection of instructions or rules which are interpretted in reponse to the user's input and make something happen.
