<span>The preservation of anything
other than mineral skeletons is (with a few exceptions described below) an
extremely rare event. Anything that can decay is likely to be lost. Fur, skin,
internal organs – all are immensely vulnerable to the destruction by
bacteria, fungi and scavengers that assure their recycling back into the ecosystem. </span>
Answer:
a: Twisted pair won't span a 400-foot distance.
Explanation:
The maximum distance that twisted pair cables can support without attenuation is 100 meters which is approximately 328 feet and the two office buildings are 400 feet apart, so it is useless to install a twisted pair cable for such a large distance. A much better option would be to install optic fiber. Though it is a bit expensive but it is the best option in this case.
Hence option (a) is the correct reason for installing an optic fiber cable rather than a twisted pair cable.
The user documents are stored in _______ format.
A. qvd.
B. qvw
C. None of the options
D. qvs.
Answer:
B. qvw
Explanation:
Given the options available, it can be inferred that the application the question is referring to is called QlikView which is a software application that is used for analytics explanation. This software applications saves documents created in a file extension specifically known as "QVW."
Hence, the right answer is that: in QlikView, the user documents are stored in QVW format.
Answer: (C) MAC
Explanation:
MAC is stand for the message authentication code and it is one of the key dependent hash function. Message authentication provide the data integrity and also the origin of data authentication.
- It basically allow the specific recipients known as the holder of the symmetric key.
- The message authentication code uses the CBC (Cipher block chaining) mode for constructing the MAC algorithm and it also uses the block cipher for the conjunction by using the CBC operations.
On the other hand, all the options are incorrect as they are not the key dependent hash function.
Therefore, Option (C) is correct.
Answer:
application software refers to the programs or series of instructions that allows us to do specific type of task on a personal computer examples word processing programs, spreadsheet programs, presentation programs among others
