Explanation of Solution
Given:
An
To find:Â The four important functions of an Operating System.
Solution:
The four important functions of an Operating System are:
The Operating System provides a user interface that can be used to perform reconstruction of a hard drive, copying and deleting files, etc.
The Operating System is used to manage files stored in DVD drives, CD Drives, and other drives.
The Operating System is used to manage hardware devices, for example managing the memory, identifying problems related to hardware, etc.
The Operating System is used for the management of installing and uninstalling applications. It also manages the interface between user and hardware.

Assume that Oscar can observe all messages sent between Rina and Naseem. Oscar has no knowledge of any keys but the public one, in the case of DS. State whether DS and MAC protect against each attack and, if they do, how. The value auth(x) is computed with a DS or a MAC algorithm. In each scenario, assume the message M = x#####auth(x). (Message integrity) Rina has the textual data x = “Transfer $1000 to Mark” to send to Naseem. To ensure the integrity of the data, Rina generates auth(x), forms a message M, and then sends M in cleartext to Naseem. Oscar intercepts the message and replaces “Mark” with “Oscar.” Will Naseem detect this in the case of either DS or MAC? If yes, how will Naseem detect it? If not, why? (Replay) Rina has the textual data x = “Transfer $1000 to Mark” to send to Naseem. To ensure the integrity of the data, Rina generates auth(x), forms a message…arrow_forward
