I do think that a man should pay for the first date or two but after that the girl can pay now and then. For my relationship i pay in the winter time he pays in the summer.
Local subnetwork domains. On a local area network (LAN), a domain is a subnetwork made up of a group of clients and servers under the control of one central security database. Within a domain, users authenticate once to a centralized server known as a domain controller, rather than repeatedly authenticating to individual servers and services.
About the difference between WAN and LAN I only known that WAN, like MAN, is for Large Area Network and LAN is for a small Area Network, like between 3 or 4 computers. You got it right, right example of WAN is internet. And LAN is cable network in your city.
