Freeware is software that is available for use at no monetary cost.

In other words, while freeware may be used without payment it is most often proprietary software, as usually modification, re-distribution or reverse-engineering without the author's permission is prohibited.

Two historic examples of freeware include Skype and Adobe Acrobat Reader.

There is no agreed set of rights or a license or an EULA which would define "freeware" unambiguously; every Freeware publisher defines their own rules for their Freeware.

For instance, redistribution of Freeware by third-parties is often permitted but there is a significant portion of Freeware which prohibits redistribution.

In cryptanalysis and computer security, password cracking is the process of recovering passwords from data that have been stored in or transmitted by a computer system.

A common approach (brute-force attack) is to try guesses repeatedly for the password and check them against an available cryptographic hash of the password.

The graphical user interface (GUI), is a type of user interface that allows users to interact with electronic devices through graphical icons and visual indicators such as secondary notation, instead of text-based user interfaces, typed command labels or text navigation.

GUIs were introduced in reaction to the perceived steep learning curve of command-line interfaces (CLIs), which require commands to be typed on a computer keyboard.

System software, or systems software, is computer software designed to provide services to other software.

Examples of system software include operating systems, computational science software, game engines, industrial automation, and software as a service applications.

A programming tool or software development tool is a computer program that software developers use to create, debug, maintain, or otherwise support other programs and applications.

The term usually refers to relatively simple programs, that can be combined together to accomplish a task, much as one might use multiple hand tools to fix a physical object.

The ability to use a variety of tools productively is one hallmark of a skilled software engineer.
