Answer to Question 1

D

Answer to Question 2

Business data communication needs may require that data be transported over great geographic distances, such as across a state, several states, a country, or even around the world. A network on this scale is called a wide area network (WAN). A WAN will very commonly use circuits provided by common carriers. In our discussion, a common carrier is a business or company that provides communication services of varying types to the general public. Common carriers include such organizations as Sprint, MCI, and AT&T, among others. A WAN can connect BNs and MANs. The infrastructures that create and support a WAN are heavily regulated. Figure 2.6 illustrates a WAN that spans a continent.
