Linux kernel

Introduction

The Linux kernel is a monolithic Unix-like computer operating system kernel. It is the central part of Linux operating systems that
are extensively used on PCs, servers, handheld devices and various embedded devices such as routers, switches, wireless access
points, set-top boxes, smart TVs, DVRs, and NAS appliances. It manages tasks/applications running on the system and manages
system hardware. A typical Linux system looks like this:

Figure 2. Typical Linux System

The Linux kernel was created in 1991 by Linus Torvalds and released as an open source project under GNU General Public
License(GPL) version 2. It rapidly attracted developers around the world. In 2015 the Linux kernel has received contributions from
nearly 12,000 programmers from more than 1,200 companies. The software is officially released on
