Answer:
There are different kinds of operating systems: such as Windows, Linux and Mac OS
There are also different versions of these operating systems, e.g. Windows 7, 8 and 10
Operating systems can be used with different user interfaces (UI): text user interfaces (TUI) and graphical user interfaces (GUI) as examples
Graphical user interfaces have many similarities in different operating systems: such as the start menu, desktop etc.
When you can recognize the typical parts of each operating system’s user interface, you will mostly be able to use both Windows and Linux as well as e.g. Mac OS.
THE ROLE OF OPERATING SYSTEM IN THE COMPUTER
An operating system (OS) is a set of programs which ensures the interoperability of the hardware and software in your computer. The operating system enables, among other things,
the identification and activation of devices connected to the computer,
the installation and use of programs, and
the handling of files.
 
        
             
        
        
        
Answer:
Following are the code to this question:
list_val = input()#defining a integer variable for input value
test_grades = list(map(int, list_val.split()))#defining test_grades as a list
sum_extra = -999 #defining sum_extra that holds negative integer value
sum_extra = 0#defining sum_extra that holds value
for y in range(len(test_grades)):#defining a for loop to check range of list  
    if(test_grades[y] > 100):# defining if block that check list value is greater then 100
        sum_extra = sum_extra + (test_grades[y] - 100)#use sum_extra variable to hold extra value and add this value
print('Sum extra:', sum_extra)#print value
Output:
101 83 107 90
Sum extra: 8
Explanation:
In the above code a, "list_val" variable is declared, that uses an input method to input the values and declared a "test_grades" variable that uses a list method to add all values in the list. 
In the next step, the "sum_extra" variable is declared, which holds some values and defines a for loop to check the range of the "test_grades", and define a if block, that checks list value is greater than 100. If the condition is true, it will remove the extra value, and add it into the sum_extera variable and add its value, and at the last use, print variable to print its value. 
 
        
             
        
        
        
Answer:
a) We know that atleast one or more author writes a book.
Symbol to indicate one or more is (B)
So the correct option is B
b) We know that zero to multiple books are written by any author.
Symbol to indicate zero or more is (A)
So the correct option is A
c) The fourth option is correct if we replace by many to many relationship and generate a new entity.
So the relationship betweem author and contract is one to many. So we know that there is atleast one author that represent in symbol d and books has atleast 0 that represent in symbol c.
So Fourth Option is correct d at blue side and c at red side.
d) There are two forirgn keys in table Contract one is from AuthorId and other is ISBN.
So correcct option is C
