Kassandra Rouse discusses open source technology and its benefits for organizations. The most commonly used operating systems are Itron, Windows, and various open source specifications from TRON. The most popular web servers are Apache, which has been at the top for over 17 years, and the open source Nginx, which is growing in popularity. Open source tools are programs for specific tasks that have openly published source code allowing for modifications. Benefits include improving code, free changes, and compatibility across servers, while potential conflicts include limited server compatibility and less security than closed codes. Open source is suitable for organizations due to flexibility, compatibility, low costs, and allowing for growth.
