If this is a computer related question; a WAN is a Wide Area Network. If you have 2 or more computers in your home or business and they are connected to each other you have a network. This is considered a local area network - LAN.If you have 2 of these groups of computers in separate locations they are each individual LANs. When you connect the separate LANs together either with dedicated phone lines (like T1) or through the internet using a 'private' (VPN is one type) connection they become a WAN.-------------------------------------------------------------------------------------------------------------------------------------------AnswerWANs or Wide Area Network are usually setup in different geographical Locations with the help of certain hardwares such as Router,Gateway and Bridge.It uses communication switching technique like Circuit,Message and Packet switching to exchange data.It used certain services to switch data ( exchange of data between nodes) likePSTN,PSDN,VAS,ISDN or Private Network.
The "network interface card" in your computer could be in a number of locations, I would need more specifics (motherboard, year, manufacture) in order to exactly tell you. But you can look at the motherboard and find out yourself.Where you plug your network cable into (RJ 45) is soldered onto your mother board with fine copper lines running from the individual pins of the soldered component. The fine copper lines are called traces, so if you trace the trace you should be able to follow it back to the NIC if the NIC is integrated. If you have an expansion card for your NIC well then... it's on there.
A metropolitan area network (MAN) is a network that interconnects users with computer resources in a geographic area or region larger than that covered by even a large local area network (LAN) but smaller than the area covered by a wide area network (WAN). The term is applied to the interconnection of networks in a city into a single larger network (which may then also offer efficient connection to a wide area network). It is also used to mean the interconnection of several local area networks by bridging them with backbone lines. The latter usage is also sometimes referred to as a campus network. Examples of metropolitan area networks of various sizes can be found in the metropolitan areas of London, England; Lodz, Poland; and Geneva, Switzerland. Large universities also sometimes use the term to describe their networks. A recent trend is the installation of wireless MANs.
The physical topology of a network refers to the configuration of cables, computers, and other peripherals. Physical topology should not be confused with logical topology which is the method used to pass information between workstations.In communication networks, a topology is a usually schematic description of the arrangement of a network, including its nodes and connecting lines. There are two ways of defining network geometry: the physical topology and the logical (or signal) topology.The physical topology of a network is the actual geometric layout of workstations.above tropologies are described belowBus - Both ends of the network must be terminated with a terminator. A barrel connector can be used to extend it.Star - All devices revolve around a central hub, which is what controls the network communications, and can communicate with other hubs. Range limits are about 100 meters from the hub.Ring - Devices are connected from one to another, as in a ring. A data token is used to grant permission for each computer to communicate.
The invention of the standard gauge made a network of railroad lines possible.
New Railroad lines :)
It allowed railroads to form a cross-country network.
The United States Railroad Administration, with the help of William McAdoo.
It allowed railroads to form a cross-country network.
The telegraph line helped significantly and the railroad was very successful due to the fact that it had three lines. Land grants made the custruslction of new telegraph linea and the railroad possible.
Railroad lines are the companies that offer rail carriers. These are like airlines or bus lines in that they offer service to customers.
Yes, Chicago has active railroad lines, commuter, long distance, and commercial.

It was a railroad junction place where two railroad lines met.
