Its important to have user accounts so you can save data and maybe log in and out of a device/cmp to another one. The purpose of the user account is to help save your stuff and personalize your device. The features are more data storage to add up, and ability to make more accounts for others so each of you can personally have their own account and save their own data on their own. Administrator accounts are the highest and have the most power of all, they are in charge of everything, especially giving permission to apps you may have downloaded and removing system apps. Users rights are the tasks specific users can do to make sure no user has too much power or less so to speak and it means what you are able/not able to do as well.
The operating system's memory protection routine intervenes and (usually) terminates the program if a program attempts to modify (or, sometimes, even to read) the contents of memory locations that do not belong to it.
Further Explanation
The memory protection routine is most commonly used in multi-programmed systems to prevent one process from affecting the availability of another. When a user opens up multiple processes, by default, they usually reside at the same time in the main memory. Sometimes, a program may attempt to access, modify, or read memory locations allocated to other processes. When this happens, the memory protection program jumps in. Keep in mind that the memory manager somehow works hand in hand with the memory protection routine. It protects the OS from being accessed by other processes and these processes from accessing one another. In addition, it helps save memory by allocating the same amount of memory to all running processes. The memory protection program, on the other hand, should be able to allow controlled sharing of memory among different processes and will usually terminate a program that tries to modify content of memory locations of that does not belong to it.

To convert the inputs to dollars and cents, we make use of a combination of multiplication and addition.
The program written in Python where comments are used to explain each line is as follows:
<em />
<em>#This gets input for the number of quarters</em>
quarters = int(input("Quarters: "))
<em>#This gets input for the number of dimes</em>
dimes = int(input("Dimes: "))
<em>#This gets input for the number of nickels</em>
nickels= int(input("Nickels: "))
<em>#This gets input for the number of pennies</em>
pennies= int(input("Pennies: "))
<em>#This converts the amount to dollars and cents</em>
dollars = quarters * 0.25 + dimes * 0.10 + nickels * 0.05 + pennies * 0.01
<em>#This prints the amount to 2 decimal places</em>
print("Amount ${:.2f}".format(dollars))
