Article title: Newbie School: full access to basic embedded Linux knowledge. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source.

　　1. what is embedded Linux?

Embedded Linux is an operating system that allows you to crop and modify popular Linux operating systems to run on embedded computer systems. Embedded Linux not only inherits the unlimited open source code resources on intelnet, but also has the characteristics of embedded operating systems.

　　2. features of embedded Linux

Copyright Fee: Free; purchase fee: media cost; technical support: free software developers around the world provide support; network features: free and excellent performance; software porting: easy, open code, there are a lot of application software support; application product development cycle: short, new products are on the market fast, because there are a lot of public code for reference and transplantation; real-time performance: RT_Linux, embedded Linux such as hardhat Linux supports real-time performance and stability: Good; security: good.

　　3. Embedded Linux has a huge market prospect and business opportunities

A large number of professional companies and products have emerged, such as Montavista, Lineo, and Emi. There are industry associations, such as Embedded Linux Consortum. Supported by world-renowned computer companies and oem board-level manufacturers, such as IBM, Motorola, and Intel. Traditional embedded system vendors also adopt Linux strategies such as Lynxworks, Windriver, and QNX. There is also support from a large number of embedded Linux enthusiasts on intelnet. Embedded Linux supports almost all embedded CPUs and has been transplanted to almost all embedded oem boards.

　　4. a wide range of embedded Linux applications

Main application fields include: PDA, STB-Set-stopbox, Digital Telephone, Answering Machine, Screen Phone, data network: Ethernet switches, Router, Bridge, Hub, remote access servers, ATM, Frame relay, Remote communication, medical electronics, transportation, computer peripherals, industrial control, aviation, etc.
