Computer Networks Answers

Design a network Scenario by yourself (Do not use the scenarios presented in the textbook or in

the lecture) where longest mask matching can be used to reduce the size of Routing table. Draw

the network scenario with proper IP addresses and subnet masks. And explain how longest mask

matching is helping here to reduce the routing table size and what would happen if we were not

following longest mask matching technique.

what is network byte order?

If the network is to be divided into four subnetworks having 50 machines each give a plan to do so. What additional devices will be needed? Give the IP address of each subnetwork and the address ranges for hosts in each subnetwork.

Does router have internet connection with network? Wired connection or Wireless connecrion?

How about modem? Does computers connect to it through internet connection , wired or wireless?

If modem or router is not available, what alternatives devices can you used? THANK YOU!

Mr. Hadi sent an email using 01 Gbps network bandwidth which contained a message size of 2.5-KB (Kilobyte) . Mr. John is 802 km away from sender who received email at speed of light travels at 2.4 × 108 m/s. You may need to calculate propagation time and the transmission time for the entire communication, and also discuss the dominant factor in this communication. Draw the figure by labelling all above mentioned values and add screen shot in your answer along with your solution.

Mr. Hadi sent an email using 01 Gbps network bandwidth which contained a message size of 2.5-KB (Kilobyte) . Mr. John is X km away from sender (where X is last 3 digit of your arid number) who received email at speed of light travels at 2.4 × 108 m/s. You may need to calculate propagation time and the transmission time for the entire communication, and also discuss the dominant factor in this communication.

One important issue in networking is the performance of the network. The question is how can measure the performance of heterogeneous networks. For example, UIIT network which provides access to students at both wired and wireless networks. In this kind of scenario: a)  You may need to define key performance parameters that can be used to evaluate the network performance.  b)If UIIT has a total bandwidth of 100Mbps and 40Mbps is reserved for admin and faculty. Due to COVID-19 pandemic total students coming daily altogether in morning and evening are 500. How much bandwidth a student can achieve if all students are using internet at the same time?                       

Mr. Hadi sent an email using 01 Gbps network bandwidth which contained a message size of 2.5-KB (Kilobyte) . Mr. John is X km away from sender (where X is 558) who received email at speed of light travels at 2.4 × 10⁸ m/s. You may need to calculate propagation time and the transmission time for the entire communication, and also discuss the dominant factor in this communication. Draw the figure by labelling all above mentioned values and add screen shot in your answer along with your solution.
