Media is always required to connect one device to another on a network. It doesn't matter if it is a client server network or a peer to peer network.

The device is looking for a DHCP server to obtain a DHCP address.
A network is an information system usually localized within a set area (buildings, or multiple sites). These multiple sites have terminals or work stations which can access the network amongst them. The mainframe or server is what manages the network through hardware and physical backing-up of the network itself.
Usually only one. A DHCP server is a Dynamic Host Control Panel, which assigns an IP to a network device. It will only give you one, and everyone using that network device will also have the same IP.
