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.
Ping. The PING utility is a system administrator's tool that is used to see if a computer is operating and also to see if network connections are intact.Ping uses the Internet Control Message Protocol (ICMP) Echo function which is detailed in RFC 792.A small packet is sent through the network to a particular IP address.This packet contains 64 bytes - 56 data bytes and 8 bytes of protocol reader information.ing uses the Internet Control Message Protocol (ICMP) Echo function which is detailed in RFC 792.
