Answer:
6 address lines
Explanation:
The computation of the number of address lines needed is shown below:
Given that
Total memory = 64MB
= 
=
Also we know that in 1MB RAM the number of chips is 6
So, the number of address lines is
i..e 26 address lines
And, the size of one chip is equivalent to 1 MB i.e. 
For a single 1MB chips of RAM, the number of address lines is

Therefore 6 address lines needed
Answer:
Following are statement is given below
int k=1,total=0; // variable declaration
while(k<50) // iterating the while loop
{
total=total+k*k;// calculating the square
k=k+1; // increments the value of k by 1
}
Explanation:
Following are the description of Statement.
- Declared a variable "total" and "k" of the "integer " type initialized the total to 0 and "k" to 1.
- Iterating the while loop for less then 50 .In this loop, we calculating the sum of square of first 50 number in the "total" variable .
- After that increment the value of "k" variable by 1 to execute the loop less then 50 .

Definition:
A "for loop" is something used for repeating things over a list of items. For instance, a list or a dictionary.
Code:
colors = ["red", "green", "blue"]
for x in colors:
print(x)
---------------------------------------------------
Definition:
A "while loop" is is something used for carrying out a set of lines that are true.
Code:
n = 1
while i < 4:
print(n)
n += 1
---------------------------------------------------
Real-Life Example:
A real-life example would if I was a manager or boss for a company say that everyone was off a certain day. Like, if I said everyone was off for Christmas the 25th. If I had 1000 employees that would take a very long time to send an email to everyone. Instead of sending an email to everyone I can program code that uses "for loops" and "while loops" to create a message and send it to everyone.

Hope This Helped! Good Luck!
Answer:
Option C is the correct answer for the above question.
Explanation:
Pishing is a type of attack which is used by the attacker to access the secured information from the system. It is used by the third person assuming for the system that he is the right use of the system and can access the information of the system.
The above question asked about the attack which can access the information to assume that he is the right user and give accessed to the network to been hacked. So the answer is phishing which is described above. Hence option C is the correct while the other is not because:-
- Option A states about direct mail which is not a type of attack.
- Option B states about instant messaging which is also not a type of attack.
- Option D states about spam which is used to send the spam messages.
- Option 'E' states about the mass mail which is used to send the lots of spam mail.
Answer:
C. sqrt(Math)
Explanation:
All but one of options A to E are is not a static method.
Only option C is a static method. The sqrt() is a static method of Math, that can always be used as Math.sqrt() is used;
The Math class defines all of its methods to be static. Invoking Math methods is done by using Math as a method rather than a variable of type Math; this means that sqrt(Math) doesn't rely on instance variables and don't need to be overridden, unlike others.
Lastly, sqrt(Math) is a static method because unlike other options, it is an utility method, and it is relevant to computations on primitive data types.
The purpose of the static method is in large part to offer a standard library of functions, and it doesn't need to be applied directly to an object.
