1, operating system
Operating system (English: operating? System, abbreviated as? OS) is a computer program that manages computer software and hardware resources, and it is also the kernel and cornerstone of a computer system.
The operating system needs to deal with basic affairs such as managing and configuring memory, determining the priority of supply and demand of system resources, controlling input and output devices, operating networks, and managing file systems. The operating system also provides an operating interface for users to interact with the system.
2. Application system
It is generally composed of computer hardware system, system software and application software. The basic hardware system of computer consists of arithmetic unit and controller, memory, peripheral interface and peripheral equipment. System software includes operating system, compiler, database management system, various high-level languages, etc. Application software consists of general support software and various application software packages.
Extended data:
The most important and basic computer software is the operating system (OS). It is the lowest-level software, which controls the programs run by all computers and manages the resources of the whole computer. It is a bridge between bare metal, applications and users. Without it, users can't use a software or program.
Operating system is the control and management center of computer system. In terms of resources, it has four functions: processor, memory management, device management and file management.
The system software not only provides the above basic functions for the application software, but also manages the hardware, so that different application software running simultaneously or successively on a computer can share the hardware equipment in an orderly manner.
For example, both applications have to save and modify data to the hard disk. If there is no coordination management organization to delimit areas for them, it will inevitably destroy each other's data.
