Sometimes abbreviated as SW and S/W, software is a collection of instructions that enable the user to interact with a computer, its hardware, or perform tasks. Without software, most computers would be useless. For example, without your Internet browser software, you could not surf the Internet or read this page and without an operating system, the browser could not run on your computer. The picture to the right shows a Microsoft Excel box, an example of a spreadsheet software program.
