"Copy and Paste" is a computer function that allows users to duplicate text, images, or files from one location and place them in another. This process involves selecting the desired item, using the "Copy" command, and then using the "Paste" command to insert the copied item elsewhere. It is commonly used in software applications like word processors and graphic design programs. This feature is available on most operating systems, including Windows, macOS, and Linux. Users can typically execute these commands using keyboard shortcuts, such as Ctrl+C for copy and Ctrl+V for paste, making it a quick and efficient way to manage information.
