The National Vulnerability Database website offers guidance on putting together a checklist to provide guidance on configuring and hardening operating systems.
An operating system (OS) is the programme that controls all other application programmes in a computer after being installed into the system first by a boot programme.
Through a specified application programme interface, the application programmes seek services from the operating system (API). Additionally, users can communicate directly with the operating system by using a user interface, such as a graphical user interface (UI) or a command-line interface (CLI) (GUI).
The development of software for computers benefits greatly from an operating system. Without an operating system, each programme would have to contain both its own user interface (UI) and the complete code required to manage all low-level computer operations, such as disc storage, network connections, and other things.

Explanation:
Web or online proxy allows you to hide your Internet Protocol (IP) address from the website you are trying to visit or access. It is like a shield between the website you are accessing and you. They can be seen as a middleman between you and the site you are visiting and as such, the site sees that a specific IP address is accessing its server but the address is not yours as all requests between your computer and the web server are first passed through the proxy server.
