Answer:
1. A browser is used to access websites and web pages whereas a search engine is used to search for particular information.
2. Indexing is the process by which search engines organise information before a search to enable super-fast responses to queries.
3.Search engines are used to find specialized data rapidly whereas web directory is used to find a list of different sites.
4. The working behind the PageRank algorithm is that a page with a large number of in- links(a link from an important page) to it, then its outgoing links to other pages also become important. It gives more importance to back links of a web page and propagates the ranking through links.
5. Look for Sites from Established Institutions 2. Look for Sites with Expertise 3. Steer Clear of Commercial Sites 4. Beware of Bias 5. Check the Date 6. Consider the Site's Look 7. Avoid Anonymous Authors 8. Check the Links

Answer:
customers += newCustomer;
Explanation:
The operator += expands into + and assignment. The assignment is not overloaded so the required code is
customers += newCustomer;
This expands into
customers = customers + newCustomer;
The overloaded + operator is called for the right expression. This returns a `CustomerList`, which is then assigned through the = operator to `customers`.
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.
