For example, while you might use your Web browser every day, you probably don't have much use for an assembler program (unless, of course, you are a computer programmer).
Since system software runs at the most basic level of your computer, it is called "low-level" software.
So again, avoiding patches will, over time, leave the software at a greater risk of attacks but also outdated and possibly incompatible with newer devices and software.
Major software companies will periodically release patches, usually downloadable from the Internet, that correct very specific problems in their software programs.
Yesterday, we made some changes to the Free Software Definition to help clarify a few points that had been confusing for people in the past.
Because this definition is the benchmark we use to decide whether or not a license is free, we want it to be as easy as possible for people to understand, and over the years we've regularly made changes to the text that do that.
You can update the software by running programs such as "Windows Update" for Windows or "Software Update" for Mac OS X.
Unlike application programs, however, system software is not meant to be run by the end user.
