True When you use a network to share software, you sometimes have to install the software on your computer, and a server on the network manages the licenses. False Files on an intranet generally are also accessible from the Internet. False The main difference between network classifications is the number of computers and devices connected to it. False A WAN can be one large network or can consist of multiple LANs. True A BAN is a type of PAN that wirelessly connects sensors worn by, carried by, implanted in, or attached to a human body. True P2P networks share a common file server. False With P2P file sharing, when a user signs out of the network, others can still access the user's hard drive. False Sometimes communications devices are preprogrammed to accomplish communications tasks. True With MMS, users can send and receive photos, videos, and audio files. True Without a data plan, you must use Wi-Fi or a wired connection to access the Internet. True Ethernet is a network standard that specifies that computers and devices on the network share or pass a special signal in a unidirectional manner and in a present order. False Because they are assigned randomly, you cannot use an IP address to determine a computer or device's location. False Bluetooth devices need to be within the same line of sight. False Bluetooth technology is standardized globally, so it can be used to connect devices that are not of the same make or True Because of its high transfer rates, UWB is best suited for transmission of large files. True T1 lines have faster transfer rates than T3 lines. False The CATV signal enters a building through a single line, usually a coaxial cable. True Some DSL installations include a dial tone, providing users with both voice and data communications. True FTTP uses fiber-optic cable to provide extremely high-speed Internet access to a user's physical permanent location. True Some smartphones can also function as a wireless modem. True Routers along the Internet backbone forward data packets to their destination using the fastest available path. True Larger networks typically use a switch, while smaller networks use a hub. False A home network can be as simple as using a cable to connect two devices. True Coaxial cable is capable of carrying significantly more signals than fiber-optic cables.

COMPUTER SCIENCE A function is called once from a program’s main function, and then it calls itself four times. The depth of recursion is _______________. a. one b. four c. five d. nine Verified answer
COMPUTER SCIENCE The greatest common divisor (GCD) of two values can be computed using Euclid's algorithm. Starting with the values m and n, we repeatedly apply the formula: n, m = m, n%m until m is 0. At that point, n is the GCD of the original m and n. Write a program that finds the GCD of two numbers using this algorithm. Verified answer
