What is Android? Everything You Need to Know

May 21, 2024

When I first started using Android, I was amazed by the things it could do. As someone who knows a lot about technology, I’ve seen this OS evolve from version 1.0 to the version 15 that we use today. Initially supporting a few devices, today it runs on over two billion devices globally.

In this article, I’ll show you what exactly Android is all about. If you are new to smartphones or simply want to learn more about it, you have come to the right place. Let’s look at what makes Android better than iPhone and explore some of its important features.

What is Android Operating System

What is Android?

Android is an open-source Linux-based mobile operating system designed for smartphones and tablets.

The name “Android” is a combination of the words “andro” (meaning man) and “oid” (meaning very similar to), which were originally used to describe robots made to appear like humans.

The term “Android” refers to an advanced, human-like operating system that lets users manage tasks on their devices easily and efficiently. A group known as the Open Handset Alliance, led by Google, developed their platform on November 5, 2007. Since it is based on Linux, a type of computer operating system that anyone can use and modify freely, this platform is found on many devices.

This makes it easier for developers because they only need to create their apps once, and then those apps can run on many different devices, including the Google Chrome OS and Windows 11.
