A "server" is a computer or system on a network that manages and provides resources, data, services, or programs to other computers (called clients) upon request, essentially acting as a central hub to distribute information across a network; you can think of it like a waiter in a restaurant taking orders and delivering food to customers.

Ask any question about servers. What hardware to use, software, opensource software.

What's your favorite type of Linux? Do you use Windows Server? Please ask to what to use with your specific project. Maybe you want to setup a TrueNas server for network storage or maybe you want to build your own opensource pfsense router for your network. Maybe you want to get in to virtualization. What's the best hypervisor? Ask any question.
