What is Linux?
Linux is an open source operating system.
An operating system is software that directly manages the system’s hardware and resources, such as the central processing unit, memory, and database. The operating system sits between the applications and the hardware, connecting all the software and the physical resources to perform the work.
The engine can run by itself, but when it is connected to the transmission, axle and wheels, it becomes a fully functional car.
If the engine doesn’t work, other parts in a perfect car won’t move either.
How does Linux work?
The Linux operating system was designed to resemble UNIX, but has evolved to be used in everything from mobile phones to supercomputers.
Every Linux-based operating system involves the Linux kernel-managing hardware resources-and the set of software packages that make up the rest of the operating system.
The operating system includes some common core components, such as the GNU core tool set and so on.
These tools provide users with ways to manage resources provided by the kernel, install additional software, configure performance and security Settings, and so on.
All of these bundled tools make up a functional operating system.
Because Linux is an open source operating system, software combinations can vary between Linux distributions.
