Glossary of terms
User Space is the area of a computer system’s memory where user programs are executed. This area is separated from Kernel Space, where the operating system kernel is executed. User Space contains programs that interact with the user, such as web browsers, text editors, graphics programs, etc. All these programs run in a virtual address space, which allows them to use memory and other system resources directly through the operating system.
User Space has limited access to computer resources and operates in a restricted environment, which helps prevent the execution of dangerous code and ensures stable operation of the operating system. Most of the usual operations performed by the user while using the computer take place in this space. User Space and Kernel Space interact with each other through system calls, which allows user programs to access the functionality of the operating system kernel.
User Space is an area separate from the operating system kernel where low-level operations such as resource management, process scheduling, memory management, etc. are performed. User Space consists of several components that ensure its functioning. One of the main elements is libraries, which contain a set of functions for interacting with the operating system and hardware. These libraries provide access to various functions, such as file management, network operations, graphical output, etc. In addition, User Space can use additional components, such as services, drivers, and other program modules that help in interacting with the operating system and other programs.
The main function of the User Space is to provide the user with the ability to interact with the computer and perform various tasks, such as launching programs, working with files, browsing the web, etc. This space allows the user to use a variety of programs and services to solve their needs.
Another important function of User Space is to ensure the security and stability of the computer. It allows you to isolate user programs from the operating system and other programs, which prevents the execution of dangerous code and ensures normal operation of the system even in the event of errors in user programs.
Artificial intelligence (AI) has become an integral part of modern life, from the algorithms that curate our social media feeds to the systems that make
In today’s fast-paced digital world, cloud automation has rapidly evolved from a cutting-edge innovation to an essential component of modern business operations. As companies increasingly
Businesses need reliable and efficient management of information flows to operate. Data collection, storage, and management require a well-developed infrastructure with workstations, database servers, storage nodes and networks, engineering networks, and data transmission networks. Building such an infrastructure requires serious start-up investments and ongoing maintenance costs. Using cloud network technology eliminates most of these problems. So what is cloud technology?
