What type of operating system does iOS and Android belong to?

1. Definition and concept of computer operating system;

A computer is a complex system that runs at high speed: It has CPU, internal memory, external memory, a variety of input, often called hardware resources, it may have multiple users running their respective programs at the same time, sharing a large amount of data, often referred to as software resources. Without a software that manages these resources uniformly, the computer is not able to accomplish the tasks that the user has entrusted to it in a coordinated and efficient manner.

From the point of view of resource management, the operating system is the software that manages the hardware resources and resources of computer system for reasonable and convenient use. It is one of the most basic software in the system software, and it is a kind of software that every person who uses computer must learn to use.

1. Classification of operating systems

According to the real-time, it can be divided into real-time operating systems and time-sharing operating system, which is divided into hard real-time operating system and soft real-time operating system.

According to the number of users, can be divided into single-user operating system and multi-user operating system.

According to the hardware structure, can be divided into network operating system, distributed operating system, multimedia operating system.

1. Analysis of advantages and disadvantages of several common operating systems; linux,windows

1. Microsoft provides the Windows operating system, currently the most widely used, by Windows XP and Windows 72, of course, there are other earlier versions 95, 98, server operating system Windows Nt,windows 2003 server and so on. Its greatest advantage or advantage is the use of extremely broad, simple operation, intuitive, application software is extremely rich, application surface is very extensive. But its operation efficiency, the security is weak.

2. Unix and Unix-based Linux, which is mainly used in server-side, and some network interactive devices, such as routers, firewalls (hardware firewall) and so on. Its greatest advantage is its security, but its disadvantage is also obvious is that the operation and configuration is more complex and professional than Windows, so the application surface and the corresponding application software is relatively narrow and less.

3. Apple's Mac OS operating system, because it is a relatively closed operating system, can only be applied to Apple's own production equipment, so the application surface is narrower. But because of the good sales performance of ipad and Apple's notebooks now, the use of the crowd also has a considerable scale. Its operation is very convenient, the user experience is quite perfect, but its application surface is much narrower.

In the peace talks on the mobile phone operating system, because the mobile device access to the Internet more and more, mobile devices, especially mobile phones, tablet computer operating system is also in the ascendant.

What type of operating system does iOS and Android belong to?

Cisco's Internet Operating system (IOS) is an operating system optimized for Internet connectivity-similar to a local operating system (NOS), such as Novell's NetWare, optimized for LANs.

Android is an open source operating system based on Linux and Java, mainly used in portable devices.
