Is there any difference between Linux and Android?
There is a difference between Linux and Android. Although Android is based on the Linux kernel, there are still big differences between the two. The main difference is: Android is mainly used in mobile devices, such as smartphones and tablets, while Linux is mainly used for backend servers.
Linux
Linux, the full name is GNU/Linux, is a set of Unix-like operating systems that are free to use and freely disseminated. A multi-user, multi-tasking, multi-threading and multi-CPU operating system based on POSIX and Unix. With the development of the Internet, Linux has received support from software enthusiasts, organizations, and companies around the world. In addition to maintaining a strong momentum of development in servers, it has also made great progress in personal computers and embedded systems. Users can not only intuitively obtain the implementation mechanism of the operating system, but also modify and improve Linux according to their own needs to maximize it to meet the needs of users.
Linux not only has stable system performance, but also is an open source software. Its core firewall components have high performance and simple configuration, ensuring system security. In many corporate networks, in order to pursue speed and security, Linux is not only used as a server by network operation and maintenance personnel. Linux can be used as both a server and a network firewall, which is a highlight of Linux.
Linux has the characteristics of open source, no copyright, and many users in the technical community. Open source allows users to tailor it freely, has high flexibility, powerful functions, and low cost. In particular, the network protocol stack is embedded in the system, and the function of the router can be realized after appropriate configuration. These characteristics make Linux an ideal development platform for developing routing and switching equipment.
Android
Android is a free and open source operating system based on the Linux kernel (excluding GNU components). It is mainly used in mobile devices, such as smartphones and tablets, and is led and developed by the American Google Company and the Open Handset Alliance. The Android operating system was originally developed by Andy Rubin and mainly supports mobile phones. In August 2005, it was acquired and invested by Google. In November 2007, Google formed the Open Handset Alliance with 84 hardware manufacturers, software developers and telecom operators to jointly develop and improve the Android system. Google then released the Android source code under the Apache open source license. The first Android smartphone was released in October 2008. Android has gradually expanded to tablet computers and other areas, such as televisions, digital cameras, game consoles, smart watches, etc. In the first quarter of 2011, Android's global market share surpassed Symbian for the first time, ranking first in the world. In the fourth quarter of 2013, the global market share of Android platform mobile phones reached 78.1%. Android, the operating system developed by Google, celebrated its 5th birthday on September 24, 2013. The number of devices using this system worldwide has reached 1 billion.
