What is Android OS?
Android is the mobile Operating System (OS) made by Google for smartphones and tablets. An OS is the basic software that makes a computer run–and your smartphone is a very powerful computer. Versions of Android are now built into many other devices, like TVs and Google’s home control products. Android OS takes care of things like interpreting voice commands, connecting to the internet, managing screens, knowing your location, interpreting gestures like swipes and taps, and handling files. In other words, Android takes care of all the basic tasks your smartphone or tablet needs to operate as a smart device.
Some companies build features on top of the Android OS
Android is somewhat of an open system, and manufacturers like Samsung and OnePlus have added their own looks and features to complement their phones. What you have on your phone may be Android or Android with additional visual and functional features.
Apps vs operating systems
The second type of software we’ll talk about are apps (short for applications). Apps are specific programs that perform a task. Your bank will have an app you can use to access your account. Facebook and YouTube are popular apps. Apps rely on the OS to operate. Your Android came with a lot of apps, like the camera, calendar, and Gmail already installed. You’ll learn how to download apps from Google Play in a later section.
Google licenses Android software to many companies that make smartphones and devices. Some of the more popular brands include Samsung, Motorola, Asus, HTC, and Sony, to name but a few. Eligible Pixel smartphones, made by Google, receive the new Android OS as soon as it is released. Updates to other Android devices may be delayed (or not available) depending upon the phone’s manufacturer and cellular carrier.
