1. Introduction to Linux operating system

**

1. What is an operating system?

Operating System (OS) is a computer program that manages and controls computer hardware and software resources. It is the most basic system software that runs directly on bare metal. Any other software must be supported by the operating system to run.

2, Linux application areas

**

1. Personal desktop applications

This area is the weakest link in traditional linux applications. Traditional linux has been suppressed by windows due to its simple interface, complex operation and few application software. However, in recent years, with the rise of excellent desktop environments such as ubuntu and fedora, and the increase of support from major hardware manufacturers, linux has gradually increased its share in the personal desktop area.

Typical representatives: ubuntu, fedora, suse linux

Play QQ in Ubuntu

2. Server area

Linux is an important branch of linux in server applications

Linux free, stable, efficient and other characteristics have been well reflected here, but early because of maintenance, operation and other reasons have also been greatly limited, but in recent years the Linux server market has been rapidly improved, especially in some high-end areas.

Typical Representative:

Red Hat AS Series

Fully open source debian series

suse EnterPrise 11 series etc.

3, embedded field

In recent years, linux applications in the embedded field have been rapidly improved

Linux runs stably, has good network support, low cost, and can be tailored according to needs. The kernel can reach several hundred KB at least, which greatly improves its application in the embedded field in recent years.

Main applications: set-top box, digital TV, network telephone, SPC switch, mobile phone, PDA, etc. are all its application fields, which have been vigorously promoted by Motorola, Samsung, NEC, Google and other companies.
