Chances are, you’ve heard of Android many times. You may even have an Android smartphone, tablet, watch, or TV. But what is Android? Android is a mobile operating system (OS) that was designed and developed by Google. The Android OS is Linux kernel-based. So, what’s “Linux kernel,” and why is that such an essential detail about Android?
In a nutshell, Linux kernel is an OS, well, sort of — it’s partially an OS. More like a small part of an OS, but an important one. The Linux kernel is the layer responsible for interfacing with the device’s hardware and managing the device’s CPU and memory. The Android OS is Linux kernel-based because the Linux kernel allows for a more open and customizable OS, which is what Android promotes — any device manufacturer can take the Android OS and make it their own.
Additionally, anyone can contribute to the actual source code that comprises Android and make it even better for all! That makes Android an open-source OS, unlike Apple iOS and Apple iPhone, for example. Android is truly open. Android is part of the Open Handset Alliance — a community of mobile and technology leaders who share the same vision of changing the mobile experience for consumers. The openness of Android makes it the number one mobile OS in the world. Hence, Android OS runs on Samsung smartphones (Samsung galaxy) and tablets, Amazon’s Kindle, Fire, and many others.
