THE INTERNET

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The internet is a relatively new system. In the 1950s, when there was no internet, tensions were high between the US and the Soviet Union. Many experts in the US worried that an attack on the telephone system might destroy communication in the country. There was a pressing need for a communication system that could better survive an attack. In this tense time, scientists came up with the ideas for the internet. Messages would be broken up into smaller pieces and sent along different paths. They’d be reassembled upon arrival. If something happened to one path, there would be others available. This early internet was called ARPAnet. The first message was sent from UCLA to Stanford on ARPAnet in 1969.Based on the passage, how was ARPAnet different from telephone communication systems?
A
Communication was quicker on ARPAnet.
B
Messages could travel farther on ARPAnet.
C
Messages could take multiple paths on ARPAnet.
D
Messages were received in secret codes on ARPAnet.
Explanation: 

Detailed explanation-1: -But this period was when the internet went mainstream, not when it was invented. In reality, the internet had been developing since the 1950s, although its early form was a mere shell of what it would eventually become.

Detailed explanation-2: -January 1, 1983 is considered the official birthday of the Internet. Prior to this, the various computer networks did not have a standard way to communicate with each other. A new communications protocol was established called Transfer Control Protocol/Internetwork Protocol (TCP/IP).

Detailed explanation-3: -ARPANET, in full Advanced Research Projects Agency Network, experimental computer network that was the forerunner of the Internet. The Advanced Research Projects Agency (ARPA), an arm of the U.S. Defense Department, funded the development of the Advanced Research Projects Agency Network (ARPANET) in the late 1960s.

Detailed explanation-4: -Twenty-five years ago today, the World Wide Web announced that it was for everybody. On April 30, 1993, the European Organization for Nuclear Research (CERN) put the web into the public domain a decision that has fundamentally altered the past quarter-century.
