What is the core of computer system software?

The core of computer system software is the "operating system". The operating system is the most basic system software that runs directly on the computer hardware. It is the core of the system software. Only the hardware equipment of the computer with the operating system can be called, otherwise the computer cannot be used; other computer software must be based on the operating system. for the platform.

In fact, the key to the design and improvement of a new operating system is the design of the system structure. After decades of development, computer operating systems have developed from a simple control loop at the beginning into a more complex distributed operating system. Coupled with the increasingly diverse needs of computer users, computer operating systems have become one of the complex and huge computer software systems.

Computer system refers to the computer hardware, software and network system used for database management. Database systems require large-capacity main memory to store and run operating systems, database management system programs, applications, databases, directories, system buffers, etc., while memory requires large-capacity direct access devices. In addition, the system should have strong network capabilities. Computer systems consist of hardware systems and software systems. The characteristics of the computer system are that it can perform accurate and fast calculations and judgments, and it has good versatility and is easy to use.
