a.
Circuit-switched network:
Circuit switched network is a process in which network nodes communicates with dedicated channel or circuit over the network. The data is divided into packets and transmitted over the network on requirement.
Packet-switched network:
Packet switched network is a process of aggregating the data packets to a single packet or device over the digital network. The data packets have a header which defines about the hardware used and a payload which is used in software applications.

- Please solve it correctly and please provide explanation of your answers. Please answer parts g, h and i. A PC and a Web Server are communicating over a TCP connection. The PC had started the three way handshake with the initial sequence number of 3069 . The Web Server's initial sequence number is 4830 . The window size of the PC is 815 bytes and the window size of the Web Server is 463 bytes. Using the third TCP handshake ack segment the PC sends the http request of the size 396 bytes to the Web Server. Then the Web Server answers with 3 segments containing the requested data. The first segment size is 42 bytes and the second segment size is 276 bytes and the third segment size is 146 bytes respectively. The PC receives all three segments within the timer. But unfortunately the second segment was corrupted. So the PC immediately sends an acknowledgement segment. Assume that the PC uses Selective Repeat/Reject ARQ. g) The second segment from webserver was corrupted. So the PC…arrow_forwardQ2- You are designing a connection mechanism between two programs, sending packets of data over the internet. You are trying to choose a size for the packets to be sent, depending on the capacity of the channel (channel bandwidth). For example, if a channel has a capacity of 10KB, then you can choose a packet size of 10KB, and send one packet, or choose a packet size of 5KB and send two packets...Etc. The problem you face is that the two programs are at two different locations, with two different channel capacities. If the first channel had a capacity of 3201KB, and the second channel had a capacity of 4565KB, find the maximum packet size that is suitable for both channels.arrow_forwardIN PYTHON Given the following six-node wide area network for which the numbers attached to the links are a measure of the “delay” in using that link (e.g., some lines could be more heavily used than others and therefore have a longer wait time), answer the following question. What is the shortest path from node A to node D, where shortest path is defined as the path with the smallest sum of the delays on each individual link? Explain exactly how you went about finding that path.arrow_forward
- As another example, consider a circuit-switched network that connects computers in two remote offices of a private company. The offices are connected using a T-1 line leased from a communication service provider. There are two 4 × 8 (4 inputs and 8 outputs) switches in this network. For each switch, four output ports are folded into the input ports to allow communication between computers in the same office. Four other output ports allow communication between the two offices. Figure shows the situationarrow_forwardPlease solve it correctly and please provide explanation of your answers. A PC and a Web Server are communicating over a TCP connection.

- The Amplitude Modulation (AM) is a technique used in communication for transmitting information via radio carrier wave. AM works by varying the amplitude of the transmitted signal in relation to the information being sent. The equations of the carrier signal, the original signal to send, and the modulated signal combining the two signals are respectively: VI-V sin (2πƒct) V2=Vm sin (2πfmt) V3=Vcsin (2πfct)+ Vm sin (2πfmt)* sin (2nfct) C Supposing that Vc =Vm=1, fc-20, fm=1. Write a MATLAB program that plots the three signals with single call, the graphs must be contain (desired title, axis labels, annotations, with symbols for color, style, and marker) for each graph. Use the step 0.0025 for the time.arrow_forwardOne way to electrically or optically represent a binary 1 or 0 is to use the transition between a voltage level (for example, going from a state of no voltage to a state of voltage, or vice versa, on a copper cable) or the transition of having light or no light on a fiber-optic cable to represent a binary 1. Similarly, a binary 0 is represented by having no transition in a voltage level or light level from one time period to the next. This approach of representing binary digits is called state transition modulation.arrow_forwardjava programming language Write a simple program that demonstrates the concept of (Multithreads) using more than one channel in the same class.

- For NAT Network Address Translation Scenario: Jenny Bello is a small business owner selling and making customized computer peripherals. She has been finding it difficult to track her sales and inventories, however recently after an expert's advice, she adopted a Point of Sale (PoS) server. So, she can now track her sales and inventories at the store. However, she ran into another issue, the server can only be accessed within the store, because it has been assigned a private IPv4 address, it is not publicly accessible via the Internet. a) Why is not having the PoS server accessible over the Internet a problem for the business? b) What caused this problem? c) Propose a solution for the problem and explain how the solution works.arrow_forward6. Consider sending over HTTP a Web page that consists of one video clip, and five images. Suppose that the video clip is transported as 25 frames, and each image has 4 frames. a. If all the video frames are sent first without interleaving, how many "frame times" are needed until all five images are sent? b. If frames are interleaved, how many frame times are needed until all five images are sent.arrow_forwardA video system can take videos from one of the two video sources, but can only display one source at a provided time. Each source outputs a stream of digitized videos on its 8-bit output. A switch with a single-bit output determines which of the two 8-bit streams will be passed on a display’s single 8-bit input. Implement a circuit that combines the two video sources, the switch, and the display. Use either ONE of the following: a single mux AND/OR an N-bit mux decoderarrow_forward
