Open-source software is computer software whose source code is released under a license in which the copyright holder grants users the rights to study, change, and distribute the software to anyone and for any purpose.  Open Source software is a development method for software that harnesses the power of distributed peer review and transparency of process. The promise of Open Source is better quality, higher reliability, more flexibility, lower cost, without predatory vendor lock-in.

The Linux kernel is an open-source monolithic Unix-like computer operating system kernel. The Linux family of operating systems is based on this kernel and deployed on both traditional computer systems such as personal computers and servers, usually in the form of Linux distributions, and on various embedded devices such as routers, wireless access points, PBXes, set-top boxes, FTA receivers, smart TVs, PVRs, and NAS appliances. The Android operating system for tablet computers, smartphones, and smartwatches uses services provided by the Linux kernel to implement its functionality.
While the adoption on desktop computers is low, Linux-based operating systems dominate nearly every other segment of computing, from mobile devices to mainframes.
Linux is the operating system for over 95% of the top one million domains
More than 80% of new smartphones sold run Android, which is based on the Linux kernel
All of the top 500 supercomputers in the world run on Linux
Most of the global markets run on Linux, including the New York Stock Exchange, NASDAQ, the London Exchange, and the Tokyo Stock Exchange
The majority of consumer electronics devices use Linux for its small footprint
More than 75% of cloud-enabled enterprises report using Linux as their primary cloud platform
Linux is the go-to infrastructure supporting the world’s ecommerce leaders, including Amazon, eBay, PayPal, Walmart, and others
You may be wondering: why would people spend hours of their own time to write software, carefully package it, and then give it all away? The answers are as varied as the people who contribute. Some people like to help others. Many write programs to learn more about computers. More and more people are looking for ways to avoid the inflated price of software. A growing crowd contribute as a thank you for all the great free software they’ve received from others. Many in academia create free software to help get the results of their research into wider use. Businesses help maintain free software so they can have a say in how it develops — there’s no quicker way to get a new feature than to implement it yourself! Of course, a lot of us just find it great fun.
