Linux Systems and Internals Programming

Embisyslabs Embedded Systems Training Institutes in bangalore courses offered on Linux system programming and Linux Internals Weekend and Weekdays. Linux is a modern Unix-like system, written from scratch by Linus Torvalds and a loose-knit community of programmers around the globe. Although Linux shares the goals and philosophy of Unix, Linux is not Unix. Instead, Linux follows its own course, diverging where desired and converging only where practical. The core of Linux system programming is the same as on any other Unix system. Beyond the basics, however, Linux differentiates itself—in comparison with traditional Unix systems, Linux supports additional system calls, behaves distinctly, and offers new features.
