Answer #1

Circuit switching is a kind of switching which generates a faithful interaction path amid of sender and receiver.it can provide the potential for preserving the messages for that moment in order to decrease the network congestion.employs a constant bandwidth.

packet switching is a kind of switching where the messages are splitted which are known as packets.generation of a Dedicated circuit is not necessary for this switching.infrastructure is a little bit hard.employs the store and forward strategy.

virtual-circuit is a way to transmit across the internet.

Draw the circuit for a three-phase full-bridge non-isolated inverter. Describe how the converter works using switching waveforms. Include a description of two different control strategies using PWM and square-wave phase difference methods. Clearly define the amplitude and frequency modulation indexes in the PWM method. Discuss and calculate the rms phase and line voltages when the DC input voltage is 400V.

Consider sending a file of 1 Mbits over a path of 5 links. Each link transmits at 10 Mbps. The network is lightly loaded so that there are no queuing delays. Propagation delay is negligible. When a form of packet switching is used, the file is broken up into 10 packets; each packet with 100 Kbits. Suppose the network is packet-switched virtual-circuit network. Denote the VC setup time by 10 milliseconds. Suppose the sending layer add a total of 100...

1.       In modern packet- switched networks, including the Internet, the source host segments long, application- layer messages (for example, an image or a music file) into smaller packets and sends the packets into the network. The receiver then reassembles the packets back into the original message. We refer to this process as message segmentation. Figure 1.27 illustrates the end- to- end transport of a message with and without message segmentation. Consider a message that is 8 · 106 bits long that is...
