What operating system is Linux and how Linux works


What is Linux?

Linux is an open source operating system.

Operating system is the software that directly manages system hardware and resources, such as CPU, memory and database. The operating system is located between applications and hardware, connecting all software and physical resources to perform work.

Xiaobian, for example, is like a car engine. Although the engine can run by itself, when it is connected with the transmission, axle and wheel, it becomes a fully functional car.

If the engine doesn’t work, other parts won’t work in the perfect car.

How does Linux work?

Linux operating system is designed to be similar to UNIX, but it has been developed to be used in everything from mobile phones to supercomputers.

Every Linux based operating system involves the Linux kernel – managing hardware resources – and a set of software packages that make up the rest of the operating system.

The operating system includes some common core components, such as GNU core tool group and so on.

These tools provide users with methods to manage the resources provided by the kernel, install additional software, configure performance and security settings, etc.

All these bundled tools form a functional operating system.

Because Linux is an open source operating system, the software combination may be different between different Linux distributions.
