Open with Google Docs I. A central monitoring computer is used to track and maintain the connections of the Internet. II. Data is routed between points in multiple ways so that if a connection fails, the data can be rerouted around the inoperative connections. III. Protocols for packets and routing are used so that computers from different manufacturers can communicate in a standard way.

Select the one that is best in each case. Which of the following explains a benefit of using open standards and protocols for Internet communication? (A) Open standards and protocols allow different manufacturers and developers to build hardware and software that can communicate with hardware and software on the rest of the network. (B) Open standards and protocols provide ways for users to eliminate the latency of messages they send on the Internet. (C) Open standards and protocols allow users to freely share or reuse material found on the Internet for noncommercial purposes. (D) Open standards and protocols prevent developers from releasing software that contains errors. Which of the following best explains how IP addresses are assigned? (A) As a new device is connected to the Internet, it is assigned an IP address to enable communication on the network. (B) IP addresses are assigned only to servers that host Web sites; user devices do not require an IP address. (C) New devices are connected to the Internet without an IP address, but are eventually assigned an IP address once they can be verified by a certificate authority. (D) New devices are connected to the Internet without an IP address; IP addresses are assigned only for encrypted communications.
