A) is a commonly used symmetric encryption
<u>Explanation:</u>
DES stands for Data Encryption Standard. It is a symmetric key algorithm and is used for encrypting electronic data. It was developed in 1975. DES is one of the oldest encryption standards to be used in the industry.
The algorithm takes 16 rounds of permutations in order to encrypt data. But now, with the advent of technology, as new algorithms have been designed and put in use, DES is less preferable.
In the process of key generation, some keys generated sometimes turn out to be weak and hence are prone to attacks. If not for the weak keys generation, DES works perfectly fine and is an effective algorithm to encrypt data.
Answer:
First two statements: yes. Last two: not so much.
But many of the better ones do have advanced degrees, but some don't.
The laboratory statement is silly; they sit behind a set of screens figuring out stuff and writing code.
Answer:
The Harmonium is not a combination of a key board and percussion musical instrument.
Explanation:
The Harmonium is not a combination of a key board and percussion musical instrument.
A harmonium, also called a "melodeon", "reed organ" or "pump organ", is a keyboard instrument that is a lot like an organ. It makes sound by blowing air through reeds, which are tuned to different pitches to make musical notes.
Answer:

Explanation:
It was the ARPANET sponsored by the US Department of Defense to enable scientists collaborate on research.
