Programming Software:

Programming software is used to aid programmers in the creation and writing of computer programs in a variety programming languages. This type of software includes editors, compilers, debuggers and interpreters. All of the software works together to allow the programmer to create an application from start to finish.

Examples of application software include Microsoft Word, Microsoft Outlook, Internet Explorer, AOL Instant Messenger and thousands of other types ranging from games to word processors.

Application software comes in many forms and a variety of price ranges. Many programmers provide their software on a shareware or freeware basis that allows you to try out their software for a small fee or for free. Other software must be purchased starting a very low cost and moving up in price depending on the application. Most of the higher end applications are developed for companies and not the average end user.

Traditionally software has been installed on the computer in order to use the application. With the popularity and easy access of the Internet, many software vendors are now providing their software via the Internet. This way the end user does not have to install anything on their system not worry about updates or issues running the software.
