In the context of software engineering and computing, OSS most frequently stands for Open Source Software. This refers to software code that is publicly accessible, allowing anyone to view, modify, distribute, and enhance the underlying source code freely. Popular examples include the Linux operating system, Apache web server, and Python. In enterprise tech operations and telecommunications, OSS can also denote Operations Support Systems, which are specialized software programs utilized by network operators to manage, provision, monitor, and troubleshoot infrastructure components and customer service levels.
