Answer:
The "service password-encryption" global configuration command encrypts passwords configured before and after the command is issued.
Explanation:
A switch is an intermediate network device that is used to transfer frames to nodes on its collision domain. It operates in the Data-link layer of the OSI model.
Switches uses media address control (MAC) table, containing the MAC addresses of the nodes in the network, to determine the destination of nodes.
In the global configuration mode in a switch, the password and other protocols are configured. The service password-encryption command in the global execution mode encrypts passwords configured before and after the command.
Answer:
Log in to iCloud.com on a browser
Explanation:
On your browser which should be a supported browser, you should log in to iCloud.com since iCloud is not supported on mac OS X earlier than mac OS X Lion 10.7.5
Answer: True
Explanation:
Subset sum problem and Knapsack problem can be solved using dynamic programming.
In case of Knapsack problem there is a set of weights associative with objects and a set of profits associated with each object and a total capacity of knapsack let say C. With the help of dynamic programming we try to include object's weight such that total profit is maximized without fragmenting any weight of objects and without exceeding the capacity of knapsack, it is also called as 0/1 knapsack problem.
Similar to knapsack problem, in subset sum problem there is set of items and a set of weights associated with the items and a capacity let say C, task is to choose the subset of items such that total sum of weights associated with items of subset is maximized without exceeding the total capacity.
On the basis of above statements we can say that subset sum problem is generalization of knapsack problem.
