System Calls | Multi Tasking | TCP/IP Networking

Linux Kernel Internals - Course Overview

The Linux Kernel Internals Course will enable you to write Linux system programs and applications by making use of system calls.Starting with OS concepts, this course will deep dive into process, memory, networking, IPC mechanisms of Linux.

The Linux Operating System has established number one position in Embedded Systems due to many reasons, one of them being robust Kernel design. This course on Linux Kernel Internals will take you through a hands-on and exciting journey.

Currently most of the embedded systems are built over an operating system due to performance requirements and the resource complexity. This adds responsibility to developers to understand the OS capabilities in form of system calls – Interfaces, API’s and system calls.

This course gives hands-on perspective on various Inter Process Communication (IPC) mechanisms like Pipes, FIFO, Shared Memory, TCP/IP Socket programming and multithreading using pThread APIs. By the end of the module you will be able to implement a multi-tasking or multi-threading application by understanding the internal aspects of Linux.

Working Professionals - Testimonials

Everyone hits the career crossroads one time or another. UpSkilling is the best way forward. Here is the list of professionals from the past who have won over their career challenges.

Got 5 Job Offers After UpSkilling

Developing solutions on my own and the belief in Best return on investment is in improving self-skills were the key motivating factors that made me reach Emertxe. Mentors helped me advance diversified skills in the Embedded domain. I could enhance my profile and started giving interviews. At one point I had 5 offers in hand to make a choice. Thanks to Emertxe.

Career Transition into Embedded

I was working in a non Embedded domain, and wanted to get back into the core. Hence I quit my job and joined Emertxe. I got help from mentors who helped me to get back into hands-on programming. Because of Helped to achieve a career transition. Mentors Helped to get the basics of embedded systems and build a career in the core domain.

What are the unique features of Linux device driver kit?

Linux device driver kit is one of the key innovations that our team has brought in the field of education. Learning device drivers is considered to be a challenging affair due to lack of proper hardware, documentation and self-learning ecosystem that consist of sample code and projects. Our team has come up with a self-learning device that addresses these limitations by bundling unique combination of hardware, software and documentation. This kit can also be used as a micro-controller kit for IoT programming by changing modes. Recently this kit related technical paper was presented in Open Source India conference, which can be accessed by clicking here. In summary you can learn device drivers like a breeze using this kit.

Can I purchase the Linux device driver kit? How?

Definitely. Self-learning kits can be purchased by anybody interested in self-learning. Request you visit self-learning kits in the web-site, choose the kit that matches your need. In each section we have provided simple ‘How to order’ section using which kits can be purchased at ease.
