Open source software (OSS) refers to software whose source code is available to the public for use and modification. Some key examples of OSS include the Apache web server, Linux operating system, Firefox web browser, and OpenOffice productivity suite. OSS development relies on peer collaboration and community involvement to create widely available products without licensing fees. OSS has many applications in fields like education, media, and government due to its low-cost and collaborative development model.
