All error-detection schemes attach additional error-detection data, based on a mathematical calculation, to the user’s message. The receiver performs the same calculation on incoming message, and if the results of the calculation do not match the error-detection data on the incoming message, an error has occurred. When is it appropriate to implement one error-detection scheme over another? Select one of the below network scenarios and develop a recommendation for implementing an error-detection scheme that best suits the scenario you choose. Address the advantages and disadvantages of the protocol and your rationale for choosing it.1. Two office computers connected via Ethernet layer2 switch, sharing a single DSL router and Internet connection.2. A rural business connects a single computer to a satellite Internet service provider and primarily conducts web browsing and research.3. A medical imaging company connects five digital imaging/scanning devices to a closed internal network where 30 computers located throughout the building can view digital imaging data in treatment rooms.4. A school has implemented network-based security cameras wired on a discrete Ethernet network that stretches across a mile-long campus. There are a total of 120 cameras that converge in a single control room where multiple computers collect, record, and provide management tools for viewing video data.
