Wide area network (wan) - spans a large geographic area such as a state, province, or country. Attenuation - represents the loss of a network signal strength measured in decibels (db) and occurs because the transmission gradually dissipate in strength over longer distances or because of radio interference or physical obstructions such a walls. Repeater - receives and repeats a signal to extend its attenuation or range. Metropolitan area network (man) - large computer network usually spanning a city. National service providers (nsps) - private companies that own and maintain the worldwide backbone that supports the internet.
