3. Several departments around campus have wireless access points, but problems arise if two wireless access points within 200 feet of each other are operating on the same frequency. Suppose the departments with wireless access points are situated as follows: Department: Math Sociology Physics Psychology History English Economics Chemistry Is within 200 feet of departments: Physics, Psychology, Chemistry, Sociology History, English, Economics, Math, Chemistry, Psychology Math, Chemistry Math, Chemistry, Sociology, Economics Sociology, English Economics, Sociology, History English, Sociology, Psychology Math, Psychology, Sociology, Physics 2 a. Draw an undirected graph that represents the table above. b. What is the fewest number of frequencies needed? How could these frequencies be assigned to departments? (Hint: if you need help, Google "graph coloring.")

Metcalfe's Law states that the value of a telecommunications network is proportional to the square of the number of connected users of the system. If a network has 20 nodes, then what is the inherent value of the network? Metacalfe's - Wikipedia A B C D 20 400 200 100
Consider the importance of wireless networks in countries that are still in the process of developing their economies at the current moment. Traditional local area networks (LANS) and cable connections have been rendered obsolete in a number of settings thanks to the proliferation of wireless technology. If we proceed in this manner, is there going to be a good result, or will there be a bad consequence instead?
More research needs to be done to better understand the significance of wireless networks in the developing nations of today, particularly those in Africa. In certain circumstances, the usage of actual wires is still necessary, while in others, wireless technology has completely replaced them. Is there any benefit to carrying out such an action, or are there any potential drawbacks?
Is it still feasible for a network to be effective and successful if it has the following three characteristics? Give specifics and an illustration.
In order for a network to be both efficient and successful, what are the three conditions that must be met?In a short window of time,
Wireless Internet is gaining importance in today's developing countries. The widespread use of Wi-Fi has rendered LANs and other wired connections obsolete. Can the present scenario be characterised as favourable or negative?
A network must satisfy three criteria in order to be considered functional. Please give me a brief description of one in your own terms.
Consider the relevance of wireless networks in nations where development is still under progress.Local area networks (LANs) and cables have been largely replaced by wireless technology in a variety of scenarios.Exists the possibility for anything positive or negative to result from this?
If a network is to carry out its duties properly and efficiently, what are the three conditions that must be met? A minute of your time is appreciated as you take the time to describe one to me in your own words.
For voice and video, the network treats them differently. All traffic would be handled equally if that were the case.
Find out the topologies of five typical networks. To what extent do you trust each?
A network is only regarded effective and efficient if all three of these requirements are satisfied; before then, it cannot be considered either. The action came to a brief halt at that point.
