security is a technology that operates the two modes: transport and tunnel
modes. Each of these modes has its own uses and care should be taken to ensure
that the correct one is selected for the solution.
<span>·
</span>Tunnel mode is most very often used between gateways, or at
an end-station to a gateway, the gateway temporarily doing the duties as a
proxy for the hosts in support of it.
<span>·
</span>Transport mode<span> is used between
end-stations or between an end-station and a gateway, if the gateway is being
treated as a host—for example, an encrypted Telnet session from a workstation
to a router, in which the router is the actual destination.</span>
Answer:Design a program that asks the user for the number of fat grams and calories in a food item. Validate the input as follows.
Make sure the number of fat grams and calories are not less than 0.
According to nutritional formulas, the number of calories cannot exceed fat grams * 9. Make sure that the number of calories entered is not greater than fat grams * 9.
Once correct data has been entered, the program should calculate and display the percentage of calories that come from fat. Use the following formula:
Percentage of calories from fat=( Fat grams * 9) / Calories
Some nutritionists classify food as “ low fat” if less than 30percent of its calories come from fat. If the results of this formula are less than 0.3, the program should display a message indicating the food is low in fat.
