What is a Clipboard, and How Does the Operating System Manage It?
The clipboard is a temporary storage area in an operating system that holds data copied by a user. It allows transferring text, images, or other types of data between different applications. Operating systems manage the clipboard through memory allocation and provide APIs to interact with it programmatically. These APIs allow developers to access and manipulate clipboard contents, enabling advanced features like copying and pasting dynamically generated data or custom formats. Clipboard.js leverages these APIs to provide seamless cross-browser compatibility.
