Open source software efforts have been behind some of the most popular applications and operating systems available, including the Android OS for smartphones and the Firefox web browser. Open source relies on community engagement, trust, and permissive licensing strategies. Compare Accounts.

The disadvantages of using open source software may include exposure to hackers. While open source code benefits from being available for further improvements within the developer community, it is also available to be viewed by malicious users who may seek out vulnerabilities to exploit. Free software refers to computer software that is distributed under terms that allow users to run copy, distribute, study, change, or improve the software for any purpose, with an emphasis on liberty rather than price.

While both open source software and free open source software essentially refer to the same set of licenses and software parameters, the difference lies in the underlying goals and philosophy. The Open Source Initiative focuses on the technicalities of the public development model and on promoting open source ideas based on pragmatic, business-case grounds.

The Free Software Initiative focuses more on the ethical issue of user rights, community cooperation, and liberation in cyberspace. Various types of open source software have been adopted in some manner by nearly every field, including but not limited to: Artificial Intelligence, Machine Learning, bioinformatics, nanotechnology, computer simulation, data mining, data visualization components, enterprise search engines, web browsers, middleware, bug trackers, game engines, healthcare software, antivirus, open source dashboard software, open source GIS software, open source relational database software, and open source database management software.

Sometimes it takes more time to debug a program than to code it. Description: To debug a program, user has to start with a problem, isolate the source code of the problem, and then fix it. A user of a program must know how to fix the problem as knowledge about problem analysis is expected. When the bug is fixed, then the software is ready to use. Debugging tools called debuggers are used to identify coding errors at various development stages. They are used to reproduce the conditions in which error has occurred, then examine the program state at that time and locate the cause.

Programmers can trace the program execution step-by-step by evaluating the value of variables and stop the execution wherever required to get the value of variables or reset the program variables. Some programming language packages provide a debugger for checking the code for errors while it is being written at run time.

Reproduce the problem. Describe the bug. Try to get as much input from the user to get the exact reason. Capture the program snapshot when the bug appears. Try to get all the variable values and states of the program at that time. Analyse the snapshot based on the state and action. Based on that try to find the cause of the bug. Fix the existing bug, but also check that any new bug does not occur. Prototype Model Definition: The Prototyping Model is a Systems Development Methodology SDM within which a paradigm output or an early approximation of a final system or product is constructed, tested, and then reworked.

It is majorly a trial-and-error process which works in an iterative fashion. Description: There are many steps within the Prototyping Model: 1. New system requirements or expectations of the system output are outlined in as much detail as possible. This requires interviewing variety of users, representing all the segments or stakeholders of the prevailing system.

A preliminary layout specification is formed for the new system. A first output model of the new system is made from the preliminary layouts. This is often a scaled-down system which tentatively gives an approximation of the desired output required.

The users check the primary output, noting its strengths and weaknesses, the things which need to be carried ahead in the next steps and the things which need to be discarded. The developer collects and examines the remarks from the all the stakeholders.

The first paradigm is changed, supported by the comments provided by the users, and is shaped to a second output of the new system. The second output is evaluated in the same manner as was the primary output. These steps are reiterated persistently, till the users are satisfied with the output. The final system is hence constructed, supported by the ultimate output.

The final system is completely evaluated and tested. Routine maintenance is administered on a seamless basis to forecast large-scale failures and to reduce the time period.

Definition: A software for which the original source code is made freely available and may be redistributed and modified according to the requirement of the user.
