Introduction:
Linux System programming is the activity of programming computer system software. It aims to produce software and platforms which provide services to other applications, operating system and hardware. The system software also manages running of the system. System programming requires a great degree of hardware awareness. Its goal is to achieve optimal use of available hardware and software resources.
The training module covers various aspects of learning with respect to developing efficient Linux based system software.

About Linux System Programming: click here...
The Linux based System Programming is all about programming in C programming language for incorporating software service in the operating system for facilitating platform for applicaitions to run, provide operating system facilities to applications and hardware.
The programmer will understand requirements about the hardware and other properties of the system that the program runs on, will exploit those properties and develop algorithms that is known to be efficient when used with specific hardware.
- It is a high level programming for facilitating low-level programming language or device hardware.
- It can operate in resource-constrained environments
- It is very efficient and has little runtime overhead
- It has a small runtime library, or none at all
- It allows for direct and "raw" control over memory access and control flow
- It lets the programmer write parts of the program directly in C or assembly language
Often systems programs cannot be run in a debugger. Running the program in a simulated environment can sometimes be used to reduce this problem.
Systems programming is sufficiently different from application programming that programmers tend to specialize in one or the other.
In system programming, often limited programming facilities are available. The use of automatic garbage collection is not common and debugging is sometimes hard to do. The runtime library, if available at all, is usually far less powerful, and does less error checking. Because of those limitations, monitoring and logging are often used; operating systems may have extremely elaborate logging subsystems.
Implementing certain parts in operating systems and networking requires systems programming.
