Application Support " UNIX/Linux "

Application Support
UNIX has plenty of application support because it is the oldest of the NOSes discussed in this chapter. However, it is important to note that applications are usually made to run on the specific
version and flavor of UNIX. For example, an application written for Sun Solaris may not run on SCO UNIX, even though they are both UNIX. Also, a large amount of UNIX software is available for free on the Internet. It can be downloaded and installed, but there may not be any technical support available for it if you get it for free.
