A parallel circuit is a different path for current through each of its components. A parallel circuit provides the same voltage across all its components and hence the same brightness of bulb. The voltage is the same in a parallel circuit while the voltage is  shared in a series circuit.nother example of a series circuit is a houehold lamp and a light switch. When the light switch is open, no current flows through it and therefore, no current can flow through the lamp either. When the switch is closed, current will now flow through the switch and the lamp.
Answer The Internet was originally developed by DARPA-the Defense Advanced Research Projects Agency-as a means to share information on defense research between involved universities and defense research facilities.arry G. Roberts created the first functioning long-distance computer networks in 1965 and designed the Advanced Research Projects Agency Network (ARPANET), the seed from which the modern Internet grew, in 1966.
Ed Clark/Time Life Pictures/ Getty Images. Mention the history of the Internet to a group of people, and chances are someone will make a snarky comment about Al Gore claiming to have invented it. Gore actually said that he took the initiative in creating the Internet [source: CNN ].hey called the network ARPANET .Â­ Without ARPANET, the Internet wouldn't look or behave the way it does today -- it might not even exist. Although other groups were working on ways to network computers, ARPANET established the protocols used on the Internet today.
