android vs linux?
Android is a free and open source operating system based on the Linux kernel (without GNU components). It is mainly used in mobile devices, such as smartphones and tablets, and is led and developed by Google Inc. and the Open Handset Alliance.
Linux, known as GNU/Linux, is a free-to-use and freely distributed UNIX-like operating system, whose kernel was first released by Linus Bennedict Tovaz on October 5, 1991. It is a POSIX-based, multi-user, multi-tasking, multi-threaded, and multi-CPU operating system, inspired primarily by the ideas of Minix and Unix. CPU operating system.
Harmony system is different from Android?
Difference between Harmony System and Android: Scope of application
The current usage scenario of Android system basically focuses on smart mobile devices, such as: cell phones, tablets, smart watches and so on. It is reported that Huawei's Hongmeng system is able to realize one-time development, multi-end operation. In addition to cell phones, tablets, watches and other conventional terminals. Similarly, TVs, cars and even smart homes can also run Hongmeng. This not only broadens the scope of adaptation of the system, but also makes cross-terminal collaboration, one-click interconnection possible. This advantage is probably the most intuitively felt by consumers in terms of the difference between the Hongmeng system and Android.
Difference between Hongmeng system and Android: performance
Hongmeng system is a full-scene distributed system based on microkernel, which has the advantages of distributed architecture, innate smoothness, kernel security and ecological **** enjoyment. The microkernel also makes the overall power consumption of the system will become very low. Android system has a large amount of redundant code, developer conference Yu Chengdong said, Android system has 100 million lines of code, the code is huge is difficult to ensure the smoothness of the system, even Android Linux kernel has 20 million lines, and the core code is frequently called only less than one-tenth.
Difference between Hongmeng system and Android: security
Android system widely criticized point is that there is no system level unified rights management and scheduling. This makes the actual experience of the user can be very cut-throat. On the one hand, the Android system requires users to pass some permission licenses, on the other hand, in the actual operation of the APP, the APP program can take the opportunity to collect information without supervision and control. Such as cottage software background collection of address book, clipboard and other data. The system structure makes the progress of privacy protection of Android difficult. Hongmeng system is said to solve the problem, because access is prohibited at the core, and all the functions are independently locked, Hongmeng system is inherently not rooted.
Which is better, android or linux?
The bottom layer (core) of Android is linux, and currently Android is applied to the RAM platform, while linux is applied to the x86 platform, two different operating systems, cell phone tablets generally use Android, computers and laptops use linux.
