Answer:
The expression to this question can be defined as follows:
Expression:
(x >= 0 && y<0) //check condition using AND operator
Explanation:
In the given question it is defined that x and y are an integer variable that holds some value, in which it defines a condition that checks the value of variable x is positive, and the value of y is negative.
- To check positive value a condition is used, that checks x greater than equal to 0, and to check negative value, it uses condition, that is y is less than 0.
- In the above condition, the AND operator is used, which executes when both conditions are true.
Answer:
The correct answer is letter "A": The message is broken into independent blocks which are encrypted.
Explanation:
There are five (5) main forms of encryption: <em>Electronic Code Book (ECB), Cipher Block Chaining (CBC), Cipher Feedback (CFB), Output Feedback (OFB), and Output Feedback (OFB)</em>. Electronic Code Book (ECB) is the simplest of all of them. Using this method to encrypt information implies dividing a message into two parts to encrypt each block independently. ECB does not hide patterns effectively because the blocks are encrypted using identical plaintexts.

Answer:
B. Generally speaking, since 2009 more people use "red" in their search terms more than they use "blue", "yellow", "green", or "purple."
Explanation:
Based on the data provided in the figure, it can be inferred that the color 'red' was used the most in the search terms compared with the other colors such as purple or green. The other colors were also used in the search terms on google, however, the trend of those that used the color 'red' in the search terms is the highest.
Answer:
False
Explanation:
The maintenance phase of the waterfall model for software development involves making changes to the entire system or some parts of it for improved performance. Integration and testing is the step at which all units developed at the implementation stage are brought together to form a whole functioning system. At this stage, the system is constantly checked for proper functionality so it can be deployed.
Noise usually means static.
