The purpose of the registry in system administration

In the absence of a registry, the operating system does not have the necessary information to run and control affiliated devices and applications and to respond correctly to user input. This is the most concise of all!Follow-up:

I don't understand, please explain it more clearly! : For example, depression is a bit like a table of contents for a book.

The system registry is a tool used to configure the Windows operating system, saving the information required by the system program, and when the program needs this information, it will be read from the registry, so the main function of the registry is to save the system information

the role played by the registry in holding information;

1. Record system installation information;

2. Set hardware attributes;

3. Windows settings and various license file extensions and application associations;

The most basic logical structure of the registry is the primary key, sub-key, key-value items and key-values, which are managed and organized according to the method of tree structure grouping, which is usually managed by the Windows operating system itself, and can also be modified by software or manually.

Purpose: The registry is a core database in the Windows operating system, which stores various parameters, directly controls the boot of Windows, the loading of hardware drivers and the running of some Windows applications, thus playing a central role in the entire system.

These functions include hardware and software configuration and state information, such as the initial conditions, preferences, and offload data of the application and explorer shells stored in the registry.

System-wide settings and licenses for networked computers, file extensions associated with applications, descriptions, statuses, and properties of hardware components, performance records and other underlying system state information, and other data.

If the registry is corrupted, it can cause the Windows boot process to be abnormal, or it may lead to the complete collapse of the entire Windows system. Therefore, it is very important for Windows users to correctly recognize, use, especially timely backup and restore the registry if there is a problem.

Purpose: 1. The registry allows the tracking configuration of hardware, certain operating system parameters, applications, and device drivers, which allows certain configuration changes to take effect immediately without restarting the system.

2. The hardware part of the data logged in the registry can be used to support the plug-and-play feature of win95. When win95 detects various devices on the machine, it saves the relevant data to the registry.

3. Through the registry, managers and users can check the configuration and settings of the system on the network, so that remote management can be realized.

The registry is a new core database that manages and configures the operating parameters of the system. Integrate all system and application initialization information in this database; It includes descriptions of hardware devices, interrelated applications and documentation files, window displays, network connection parameters, and even network settings related to computer security.
