The Android OS and iOS both operating systems are made for mobile devices, especially for touch screens devices such as smartphones and tablets. An android operating system is an open-source software developed by Google whereas iOS operating system is developed by Apple Inc.
Exclusively for its hardware i,e iPhone, iPod, iPad, etc. While there are lots of similarities and differences between the two operating systems, both of the operating systems are widely popular globally. iOS is considered as the second most popular mobile operating system after Android.
The android operating system is based on the Linux kernel and has the ability to freely modify, invent and implement our own device drivers and features.
There are five different layers of an Android Operating System. The first layer is the Application Framework for developers to create apps using a programming language Java in SDK,
The second is Binder IPC Proxies(This interface allows a programmer to make an application to communicate with other applications. ), the third consists of the Android System Services(The system services of android provide necessary information to the user applications in order for them to work properly).
Fourth is the Hardware Abstraction Layer( Allows the Android application/framework to communicate with hardware-specific device drivers), and the last being the Linux Kernel(It manages the operations of the computer and the hardware, most notably memory and CPU time).
Android operating system supports lots of programming languages such as Java, C, C++, XML, Assembly language, Python, Shell script, etc, However, Java is the most popular and preferable programming language for Android app development.
The iOS operating system and its architecture are layered. It contains an intermediate layer between the applications and the hardware so they do not communicate directly.
The lower layers in iOS provide the basic services and the higher layers provide the user interface and sophisticated graphics.
The layered architecture of iOS is as follows, the first layer is Cocoa Touch( It is a user interface framework provided by Apple for building software applications), the second is Media Layer(Graphics, audio, and video are handled by the Media layer), the third layer is core services(It is fundamental system services that native iOS applications use), and the fourth layer is Core Os. The iOS operating system supports Objective-C, C, C++, Swift programming language for building iOS applications.
The basic functions in iOS and Android are alike. Both iOS and Android phones have calling, messaging, web browsing, video chat, maps, voice commands, etc.
The user interfaces of iOS and Android have a lot of similarities. Both of this support swiping, tapping, pinch and zoom, etc on their phone screens.
There is a status bar on both the iOS and Android devices and it offers similar information such as battery life, time, app notifications, wifi, etc. 4G cellular network can be enjoyed on both the iOS and Android devices. This is very important as the cellular network is crucial for internet surfing.
Privacy settings are paramount in both iOS and Android. Users are presented with app permissions as this lessens the risk of data leakage.
