For an inexpensive file server to share photos and videos while avoiding complicated licensing, the technician should recommend: * Linux: Linux is a free and open-source operating system that is ideal for setting up a file server. It offers robust file-sharing capabilities with minimal licensing complications. * Chrome OS: Designed primarily for lightweight, web-based tasks and not ideal for a file server. * macOS: Requires Apple hardware and involves more complex licensing compared to Linux. * Windows: While capable of being a file server, Windows may involve licensing fees, particularly for server editions.
