Question 6 [8 points] A system transmitting synchronous frames operates at a bit rate of 56...
Please answer this 2 part question! Please show all work (15 points) The bit stream 1110 0111 1010 is transmitted using the standard CRC algorithm described in the book. The generator polynomial is r + x + x + 1. Show the actual bit string transmitted. Suppose that the THIRTEENTH (13th) bit from the left in the transmitted message is inverted during transmission. Show that this error is detected on the receiver's end. Show every step in your calculations for...
help with computer network questions 1. What is the difference between circuit switching and packet switching? 2. What are the different layers in today’s Internet? Why do we create layers? 3. Suppose there is a 10 Mbps microwave link between a geostationary satellite and its base station on Earth. Every minute the satellite takes a digital photo and sends it to the base station. Assume a propagation speed of 2.4 * 10^8 meters/sec. a. What is the propagation delay of...
Question#1 1. What is the difference between a BSS and an ESS? 2. Discuss the three types of mobility in a wireless LAN. Question#2 A network using CSMA/CD has a bandwidth of 10 Mbps. If the maximum propagation time (Including the delays in the devices and ignoring the time needed to send a jamming signal, as we see later) is 25.611US, what is the minimum size of the frame? Question#3 Assume that, in a Stop-and-Wait ARQ system, the bandwidth of...
Please Answer all Questions on Networks, They all involve calculation ( 1-9 Questions) "A single router is transmitting packets, each of length L bits, over a single link with transmission rate R Mbps to another router at the other end of the link. Suppose that the packet length is L= 12000 bits, and that the link transmission rate along the link to router on the right is R = 1000 Mbps. What is the maximum number of packets per second...

Question 2 options: True False Question 3 (1 point) Saved Consider two hosts, A and B, connected by a single link of rate R bps. Suppose that the two hosts are separated by m meters,...
summatize the following info and break them into differeng key points. write them in yojr own words apartus 6.1 Introduction—The design of a successful hot box appa- ratus is influenced by many factors. Before beginning the design of an apparatus meeting this standard, the designer shall review the discussion on the limitations and accuracy, Section 13, discussions of the energy flows in a hot box, Annex A2, the metering box wall loss flow, Annex A3, and flanking loss, Annex...
