Scenario
A high-speed Internet connection is suitable in order to connect all computers on the home network to the Internet.The three primary ways for home users to obtain a fast connection to the Internet are Digital Subscriber Loop (DSL),cable,and satellite.DSL is provided by telephone companies,cable is provided by cable TV companies,and satellite connections are provided by satellite TV providers.DSL shares the same phone line as the telephone service,but it uses a different part of the phone line's bandwidth.It does not interfere with normal phone service because there is a significant amount of unused capacity in current phone wires.Each has its advantages and disadvantages,including the minimum and maximum speed of Internet access,cost,and availability.
Determining the optimal high-speed Internet connection depends largely on where the network will be located,local costs,and service availability.The way to obtain the best high-speed Internet connection is to research the options available in your area.
Assume you live in prominent town area.You have decided that high-speed Internet access and a Wi-Fi network would be advantageous for your home use.Find answers to the following questions for this township.
Produce a report emphasizing the following requirements:
a) Describe the technology involved,giving a clear indication of methods of high-speed Internet access that are available.
b) Which service provides the best service?Which is the cheapest?Justify your answer.
c) Describe with examples the importance of Wi-Fi technology (i.e.how the technology has or will affect human beings at work and social life).
d) Describe the criteria required for the successful implementation of the Wi-Fi technology (i.e.the basic requirements such as hardware,software,skills,cost,etc.).
e) Describe under what circumstances the technology can be implemented (i.e.any special considerations or pre-requisites such as safety,security,regulation,etc.).
f) Describe where such technology is best suited for implementation (i.e.for specific industry and locality).
g) Describe the advantages / strengths for implementing Wi-Fi technology.
h) Describe the disadvantages / problems for implementing Wi-Fi technology.
i) Based on the information you gather,write a plan for subscribing to a high-speed Internet connection service using relevant diagrams,figures and provide a simple illustration of the implementation of the chosen standard.
