"Server" has many implication and definitions, once such
definition is that of a
game server which is a piece of hardware that allows for an instance of a
game to be running. A server comes in many forms, some of which are dedication and ran as an individual piece of hardware, usually not having any displaying device and only utilising software to maximise the servers performance. Servers can also be ran by individuals that are not dedicated, these servers usually
run parallel with a systems normal functions and hence generally are not very stable and do not provide insane amounts of stability for those connected. These servers are usually volatile and cease to
run once
power to the system has been relinquished.
You can also
ask someone where a server is by simple putting their name and then the word server afterwards. You can also use other words to ask for a server such as "sulfur?" "server her" "Sir Vir?"
