Final answer:
The 'core' or minimal installation option of server software requires the least amount of system resources, typically lacking a graphical interface and focusing on essential features to maintain a smaller footprint.
Step-by-step explanation:
In the context of server software, the edition that requires the least amount of system resources to install would typically be the 'core' or minimal installation option. This version is often designed for use in scenarios where limited system resources are available, or when a lightweight, efficient server is necessary. It would generally have a smaller footprint, reducing disk space requirements and system overhead, as it omits many of the graphical and management tools found in more fully-featured editions.
For example, with Microsoft Windows Server, the 'Core' installation option is a stripped-down version of the operating system with no graphical interface and only essential features. This reduces its system resource requirements significantly when compared to the full 'Desktop Experience' version. In the Linux domain, a minimal install of a distribution like Ubuntu Server or CentOS without a graphical user interface would be the choice requiring fewer resources.
