Suppose two hosts A and B are separated by 10,000km and are connected by a direct link of R= 1Mbps. Suppose the propagation speed over the link is 2*10 ^8 m /sec. Consider sending a file of 900,000 bits from host A to host B
a. Suppose the file is sent continuously as one big message. How long does it take to send the file assuming it is sent continuously.
You have been contracted to make a network for a multimedia development firm which currently uses 10-Mbps Ethernet network. Company needs a high-bandwidth network for multimedia team.
Explain which concepts are the most significant to consider when designing information security policies and procedures.
Assume that we are working on a workstation with an instruction rate of 500 MIPS. How many instructions can the processor execute between the receipt of each individual bit of the message?
Suppose a subnet with prefix 128.119.40.128/26. Provide an example of one IP address (of the form xxx.xxx.xxx.xxx) which can be allocated to this network.
You have been hired by a small company to install backbone to connect four 100base-T Ethernet LANs (each using one 24-port hub) and to give a connection to Internet. Develop simple backbone and determine total cost.
Assuming you use a straight-through (not a crossover) cable, what port on hub A will you use to connect it to hub B?
Post note describing an example where IP would be the best solution method. at lease 100 words. Where do we go from here with Operations Research and Management Science?
Terminal A is sending data to terminal B using a sliding window protocol with the window size equal to 5 and the maximum sequence number equal to 6.
Suppose the university has the 128.100.xxx.xxx address range on the Internet. How would you assign the IP addresses to the various subnets?
Research to see how the Internet is put together. What are some key pieces of the basic architecture of the Internet?
What kind of network crimes may use P2P networks? Find the most challenging crimes that could be based on P2P networks and write a report on how to do forensic investigations on these crimes.
