The programs run on the server; the user manages them on the client by sending mouse movements and keystrokes to the server.
During desktop sharing, applications that use remote desktop protocol (RDP) or proprietary protocols send screen content as terminal servers. This is sent over the network to one or more clients (multichannel) in the form of primitives, a mixture of images and information. They can even transmit the desktop sound if needed. The users then work on the server's desktop, alone or in parallel with other users, as if sitting directly in front of it.
