Content

What is Operating System?

==> An operating system (OS) is the program that, after being initially loaded into the computer by a boot program, manages all of the other application programs in a computer. The application programs make use of the operating system by making requests for services through a defined application program interface (API). In addition, users can interact directly with the operating system through a user interface, such as a command-line interface (CLI) or a graphical UI (GUI).

What is Linux?

==>Linux is an operating system that was developed by Linus Torvalds in 1991. The name “Linux” originates from the Linux kernel. It is an open-source software that is completely free to use. It is used for computer hardware and software, game development, mainframes, etc. It can run various client programs.

Everyday use of Linux.

  • US Agencies
  • NASA
  • Health Care
  • Bullet Train in Japan
  • Traffic Control
  • Financial institutes
  • World Commerce leaders.

Linux Distribution.

  • RedHat(not Free)
  • CentOS
  • Fedora
  • SUSE
  • Debian
  • Ubuntu


Linux vs Windows

Linux Windows
Price Free $$$
Ease Not-User friendly User-friendly
Reliability Very-reliable Often-require reboot
Multi-tasking Best for Multi-tasking Multi-tasking is available but very high CPU and Memory required
Security Very Secure Some How Secure
Software Mostly enterprise level software Most Larger Selection of Software eg, office, games
Open Source Open to Public Not an Open Source


Linux vs Unix

  • Linux is an operating system that was developed by Linus Torvalds in 1991. The name “Linux” originates from the Linux kernel. It is an open-source software that is completely free to use. It is used for computer hardware and software, game development, mainframes, etc. It can run various client programs while,
  • Unix is a portable, multi-tasking, bug-fixing, multi-user operating system developed by AT&T. It started as a one-man venture under the initiative of Ken Thompson of Bell Labs. It proceeded to turn out to become the most widely used operating system. It is used in web servers, workstations, and PCs. Many business applications are accessible on it.
