Understanding the Fundamentals of Linux

1. What is Linux?

   • Linux is an open-source, Unix-like operating system that was first released in 1991 by Linus Torvalds.
   • It is kernel-based and designed to run on a wide range of devices, from personal computers to supercomputers and embedded systems.
   • Linux is known for its robustness, security, and flexibility, making it a popular choice for servers, desktops, and various applications.

2. Who invented Linux and what is its history?

   • Linux was created by Linus Torvalds, a Finnish computer science student, in 1991.
   • Torvalds initially developed Linux as a personal project to create a free and open-source operating system kernel.
   • The Linux kernel was then combined with other components, such as the GNU utilities and libraries, to form a complete operating system.
   • Over time, Linux gained popularity and a large community of developers contributed to its growth and improvement.

3. What is the difference between Linux and Unix?

   • Linux and Unix are both multi-user, multi-tasking operating systems, but they have some key differences:
     • Unix is a proprietary operating system developed by AT&T, while Linux is an open-source operating system.
     • Unix is typically more expensive, while Linux is free to use and distribute.
     • Linux is designed to be more portable and can run on a wider range of hardware platforms.
     • Unix follows a more strict set of standards and guidelines, while Linux is more flexible and adapts to various needs.

4. What is the Linux kernel?

   • The Linux kernel is the core component of the Linux operating system.
   • It is responsible for managing system resources, such as memory, processes, and hardware devices.
   • The kernel acts as an intermediary between the hardware and the software, providing an abstraction layer that allows applications to run on different hardware platforms.
   • The Linux kernel is open-source and can be modified by developers to fit specific needs or add new features.
