Android is an open-source operating system developed by Google and the Open Handset Alliance for use in mobile devices. It uses a modified Linux kernel and other open source software, allowing developers to write managed code in Java for the applications. The Android platform includes features like storage, connectivity, messaging, web browsing, media support, and multi-touch. It is designed to be adaptable to various hardware configurations and uses Linux for its underlying functions. The architecture of Android is based on a modified Linux kernel with libraries and APIs written in C/C++.

8. PLATFORM
HARDWARE
 Android
is not a single piece of hardware;
it's a complete, end-to-end software
platform that can be adapted to work on
any number of hardware configurations.
Everything is there, from the bootloader all
the way up to the applications

9. PLATFORM
OPERATING SYSTEM

Android uses Linux for its device drivers, memory
management, process management, and networking.

The next level up contains the Android native
libraries. They are all written in C/C++ internally, but
you’ll be calling them through Java interfaces.

10. PLATFORM
NETWORK CONNECTIVITY
It supports wireless communications using:
