What is a license server?

A license server is a specially configured computer that serves (provides) floating licenses to Keysight products running (typically) on other machines (the licensing clients in the client/server architecture). It is sometimes referred to as a remote license server to indicate that it is running on a different machine from the licensed Keysight products.

To function as a floating license server, a machine must run the FlexNet Publisher license server manager (lmgrd) and the Keysight vendor daemon (agileesofd).
The license files are installed on the license server machine. (You or your system administrator will install them there.)
Each client machine is configured to request its licenses from that server. (See Specify a Remote License Server.) You can also configure a client to get its licenses from multiple license servers; in that case, when you run the licensed software, it requests the needed license from each server in turn until a request is successful (meaning that server had the correct license available).
In this way, many users/machines can share a pool of licenses. Each machine uses only the licenses needed for the Keysight products it is running at that time; when a user closes or stops a licensed product, the license is returned to the server's pool and can be used by someone else.
