Linux is a Unix-like computer operating system that was brought together under the model of free and open-source software development and distribution. Its main component is the Linux kernel, which was first released to the public on September 17, 1991, by Linus Torvalds. Android takes advantage of the Linux Kernel, since Linux is an open-source operating system. Google’s Android developers manipulate the Linux Kernel to suit their own needs. Linux provides the Android developers a pre-built, already maintained operating system kernel to start up with so that they do not have to write their own kernel from scratch. Although Android is developed based on Linux, it does not entirely employ the standard Linux kernel in its use. The two vary in regards to their features and nature of their functions. Android does not include the GNU software and libraries; Android includes very little GNU software, thus as GNU software, is a defining characteristic of a Linux distro. By default, the Android Operating doesn’t allow for customization unlike Linux Distributions which are pretty easy to customize; Android device owners don’t have root access to the underlying operating system. You cannot run Linux apps on Android; Android has very little software in common with other Linux distros, making it impossible to run regular Linux apps on Android. In the end, the Linux kernel is regarded as the most popular Operating System while Android is a framework built on top of the Linux kernel.
