Answer: Strong 128-bit encryption.
Explanation: An individual character corresponds to 8 bits . So if there are 16 characters then,
16
8=128 bits keys
This makes the 128 bit key encryption the strongest amongst all other options.It is strongest because it is almost impossible to decode the 128-character key by any method e.g.-brute-force method.
Other options are incorrect because the characters given by the other bits are as follows: 
=32 characters
=64 characters
=128 characters
Thus, the strongest character key is of 128 bits. for cipher.
Answer:
Phased installation
Explanation:
The name of this strategy is phased installation. Phased installation (or phased implementation) occurs when an existing system is replaced by a new one. However, unlike most implementations, this takes place in stages. This has several advantages. First, it allows you to test the system. If there is a problem with it, it is easier to revert back to the old strategy. Moreover, if employees need to adopt this new system, it allows them to get used to it slowly while still being able to access the previous one.
Answer:
The answer to the following question is the option "B".
Explanation:
In computer science, the term Reliability is an attribute for any computer-related element like software or hardware. It consistently acts according to its terms. It has a lengthy process for considering one of three similar properties that must be analyzed when using a computer component. So the answer to this question is option B which is "0.684".
Cloud computing allows computers from all around the world that are not being used to be able to do extra computations. This removes many of the limitations of a single computer and lets the user calculate things much faster.
