Linux is an operating system, while the other options are networks or operating systems.
- Internet is a global system of interconnected computer networks that use the standard Internet protocol suite (TCP/IP) to serve billions of users worldwide. It is a network of networks that consists of millions of private, public, academic, business, and government networks, of local to global scope, that are linked by a broad array of electronic, wireless, and optical networking technologies. The Internet carries an extensive range of information resources and services, such as the inter-linked hypertext documents and applications of the World Wide Web (WWW), electronic mail, telephony, and file sharing.
- Windows is a group of several proprietary graphical operating system families, all of which are developed and marketed by Microsoft. Each family caters to a certain sector of the computing industry. Active Windows families include Windows NT and Windows IoT; these may encompass subfamilies, e.g. Windows Server or Windows Embedded Compact (Windows CE). Defunct Windows families include Windows 9x, Windows Mobile and Windows Phone.
- Unix is a multitasking, multiuser computer operating system that exists in many variants. The original Unix was developed at AT&T’s Bell Labs research center by Ken Thompson, Dennis Ritchie, and others. Unix was first released in 1971 and has been under constant development ever since. It is one of the most widely used operating systems in the world, and is used on a wide variety of computer hardware platforms.
Linux is a Unix-like operating system based on the Linux kernel, an operating system kernel first released on September 17, 1991, by Linus Torvalds. Linux is typically packaged in a Linux distribution. Linux distributions include the Linux kernel and supporting system software and applications that are often freely distributed. Many Linux distributions are available, and most of them are free and open-source software.
