Answer: data loss protection
Explanation:
In any organization or enterprise it is very essential to provide protection from data loss to avoid breaches by unauthorized accesses and to secure the data irrespective of whether it is in rest or motion.
It is known that data changes its form when it is copied, moved and stored in different memory location so in this process a lot of sensitive data might be exposed to the outside world and left into the hands of the unauthorized for easy of access to it.
So once a security breach is possible through the system or into the network of the organization it would expose all the application database, emails, spreadsheets and the personal workstation files. So in such a scenario the importance of data loss protection is highlighted and must be given due importance.
Answer:
x = int(input("What grade are you in? "))
if(x == 9):
print("Freshman")
elif(x == 10):
print("Sophomore")
elif(x == 11):
print("Junior")
elif(x == 12):
print("Senior")
else:
print("Not in High School")

Answer:
b. foreign key
Explanation:
In the database world, a foreign key is a field on one table and a primary key for another table. The purpose of a foreign key is to provide linkages between two or more tables. Given two tables A and B, and making A the point of reference, a primary key is a field that is unique in A while a foreign key is unique in B.
On another hand, a composite primary key is a combination of two or more fields/columns on database table that can be used to uniquely identify each row in the table.
In the database lingua, what we have is a unique key not a distinct key, though the two words are similar in meaning.
A duplicate key is used when an information may be repeatedly entered on a table.
So the correct option is a foreign key.
Answer:
3 bits
Explanation:
Given a 4- way set associative cache that has 64 blocks of 16 words.
Therefore, the number of sets cache has:
Now,
Cache data size is 16kB
The number of cache blocks can be calculated as:
Now,
Total sets = 
Total sets = 
Now,
n = 6
For 15 bit address for the architecture, the bits in tag field is given by:
15 - (6 + 6) = 3 bits
Thus the tag field will have 3 bits
