What is the total number of communication lines needed for a fully connected network of eight computers?

x(x-1)=2y 8*7/2=28 28 lines


WAN stands for?

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.


What is the difference between a modem and a NIC card?

Oh, dude, a modem is like that thing that connects you to the internet, while a NIC card is like the thing that helps your computer communicate within a network. So, it's like the modem is the gateway to the internet, and the NIC card is the social butterfly of your computer, making friends with other devices. They're both important, but in different ways, you know?


What is the location of the NIC chip in your computer?

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.


What do you mean by metropolitan area network?

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.
