Answer:
D. Government and law enforcement want access to encrypted messaging apps to help fight criminals and terrorists.
Explanation:
The explanation is simple: if a messaging application has encryption implemented into its functionality, then it means one of the purposes of that application is maintaining the privacy of the end user.
If a government and the law enforcement under that government want access to encrypted messaging applications with the intention of fighting criminals and terrorists -- which is an altruistic act to maintain security in the country -- this defeats the purpose of maintaining the end user's privacy if the developer(s) of the app were to hand over that data to a government and the law enforcement under them.
This is a famous example of security vs privacy, actually.
Answer: Instruction count
Explanation: Instruction count is the most general and least useful performance matrix for RISC machine because RISC is known for the reduced set of instruction so indirectly the instructions are less so there is not much requirement of keeping the count of instruction.other features mentioned in the question describes the performance factor of RISC machine and are the major factor behind the working of the RISC machine.
Answer: 2 ^56 times more unique user ID's can be represented in the system.
Explanation:
5 bits will produce a maximum data allocation for User ID entries of 2^ 10.
12 bits will produce a maximum data allocation for User ID entries of 2^ 66.
Therefore the number of times more unique user ID's will be represented is 2^(66-10) = 2 ^ 56 times.
The correct answer is: [B]:

Answer:
dog
Explanation:
Given the code :
>>> A = [21, 'dog', 'red']
>>> B = [35, 'cat', 'blue')
>>> C = [12, 'fish', 'green']
>>> E = [A, B, C]
the value of E[0][1]
Here, square boxes is used to select the value at E[0] ; the output is then used to select the value at index 1 of E[0] output.
Note that, indexing starts at 0; hence first list element is 0, then, 1, 2, and so on.
At
E[0] ; list E, index 0 (first element in the list) , gives an output A
Then, A[1] ; list A, index 1 (second element in the list) gives 'dog'
