32.
Videoconferencing allows participants to collaborate as if they were in the same room.

33.
Wireless transmission use cable and other tangible (touchable) materials to send communications signals.
34.
Coaxial cable is insulated less heavily than twisted-pair cable, and thus is more susceptible to noise.
35.
Although each network that constitutes the Internet is owned by a public or private organization, a single organization owns and controls the Internet.
36.
Computers manipulate and organize data into information.
37.
While the World Wide Web was developed in the late 1960s, the Internet came into existence less than a decade ago - in the early 1990s.
38.
