over wide areas. These networks are installed nationwide in all industrial
countries, and can be used without restriction for business and private
communication. Such networks are conceived keeping in mind the service
offering. Therefore, the classical analogue telephone network (POTS), just
like ISDN, is suitable for telephony. The public data packet networks, on the
other hand, were conceived for data transmission services. ATM, Frame
Relay and Fast Packet Switching are also worth naming in this connection.

computer names in Windows networks to IP addresses. The WINS method
takes into account that two computers with the same name or the same IP
address are never logged into the network.
With WINS, which uses the UDP protocol for transmission, the started client
logs on to the WINS server with its NetBIOS name and the IP address. The
latter checks whether the addresses are not already in use and enters them
in the address database of the WINS server. When a client logs off, the
address is released again and can be reassigned.
