What is Open Source?
Open source describes software where the source code is available for anyone to view, use, change, and then share. Making source code publicly available allows others to build on and learn from it, enabling broad collaboration from people around the world.
It's in your phone, your car, your TV, and your wifi-connected light bulbs. Open source components enable engineers to build on the work of a global community of developers to deliver better products faster and at lower cost. Linux, the Apache web server, Android, Firefox, and WordPress are examples of open source projects you may have heard of.
