Installing from an image refers to the process of creating a copy of a computer system or software environment, and using that image to install the same system or software on another computer or device. An image typically contains all the necessary files, settings, and configurations required to install the system or software. Installing from an image can save time and effort compared to manually installing and configuring the system or software on each device. It also helps ensure consistency and uniformity across devices, reducing the risk of errors or discrepancies. Effective installation from images requires proper planning, testing, and documentation to ensure successful deployment and minimize disruptions.
