Linux was created in 1991 by Linus Torvalds as an open-source alternative to the proprietary Minix operating system. Some key features of Linux include its portability across different hardware, its open-source and collaborative development model, its ability to support multiple users and programs running simultaneously, its hierarchical file system, and its built-in security features like password protection. Linux also provides advantages over other operating systems like Windows by being free, allowing for custom modifications, and providing highly secure and robust servers.

- 6. ADVANTAGES OF LINUX OS Its a free Operating System unlike windows which has to be purchased. Other benefits are being open source, anyone with programming knowledge can modify it. Once installed in your system, no antivirus required. Linux is a highly secure system.
- 7. ADVANTAGES OF LINUX OS With its upgrades Linux becomes more secure and robust. Companies like Amazon, Google, Facebook use Linux for their servers. Linux based servers could run non-stop without a reboot for years.
