3. Unix is an operating system whose development started in 1969 at the Bell Labs research center by Ken Thompson, Dennis Ritchie It supports multitasking and multi-user functionality. Unix is most widely used in all forms of computing systems such as desktop, laptop, and servers. On Unix, there is a Graphical user interface similar to windows that support easy navigation and support environment

4. Cont. Initial release date   November 3, 1971 OS family   Unix Programming languages:  C, Assembly language Developer   FreeBSD, Nokia Bell Labs

5. Linux student at the University of Helsinki, Torvalds started developing Linux to create a system similar to Unix OS. Linux is a Unix-like, open source and community-developed operating system (OS) for computers, servers, mainframes, mobile devices and embedded devices . is supported on almost every major computer platform x86 and x64

6. History of Linux Linux , computer operating system created in the early 1990s by Finnish software engineer  Linus Torvalds  and the  Version 1.0 of the Linux kernel , In 1991 he released version 0.02 . kernel is the main component of a Linux operating system (OS) and is the core interface between a computer's hardware and its processes

7. How is the Linux operating system used? Every version of the Linux OS manages hardware resources, launches and handles applications, and provides some form of user interface. The enormous community for developers and wide range of distributions means that a Linux version is available for almost any task, and Linux has penetrated many areas of computing.

8. Cont. Server OS  for web servers, database servers, file servers, email servers and any other type of shared server. Designed to support high-volume and multithreading applications, Linux is well-suited for all types of server applications. Desktop OS  for personal productivity computing. Linux is an open source and freely available desktop environment for users who prefer it to commercial OSes. Headless server OS  for systems that do not require a graphical user interface (GUI) or directly connected terminal and keyboard. Headless systems are often used for remotely managed networking server and other devices.

9. Cont. Network OS  for routers, switches, domain name system servers, home networking devices and more. For example, Cisco offers a version of the Cisco Internetwork Operating System (IOS) that uses the Linux kernel. Software development OS  for enterprise software development. Although many development tools have been ported to Windows or other OSes, Linux is home to some of the most widely used open source software development tools. For example, git for distributed source control; vim and emacs for source code editing; and compilers and interpreters for almost every programming language.

10. Cont Cloud OS  for cloud instances. Major cloud computing providers offer access to cloud computing instances running Linux for cloud servers, desktops and other services.

11. Cont. Linux is highly configurable and depends on a modular design that enables users to customize their own versions of Linux. Depending on the application, Linux can be optimized for different purposes such as: networking performance; computation performance; deployment on specific hardware platforms and deployment on systems with limited memory, storage or computing resources

12. Types of Linux OS There are more types of Linux OS Debian Linux. Gentoo Linux. Ubuntu Linux. Mint Desktop. RHEL Linux . CentOS Linux. Fedora Linux. Kali Linux. Open-SUSE Linux.

22. Windows Windows dates far back to 1981 when Microsoft began work on a project called “Interface Manager.” Later renamed Windows in 1983. The first official version of Windows, however, wasn’t released until November 1985. Microsoft built the early Windows as a graphical user interface (GUI) extension of their MS-DOS operating system .
