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:
b. template<classT>.
Explanation:
Template functions are that can work with generic types. Template lets us to create a function so that more than 1 type or class can adapt the functionality of that function.
We can write the template function as following:-
template<class typename>.
It matches to the option b.
In think is C or B in my opinion
Answer:
Input devices: For raw data input.
Processing devices: To process raw data instructions into information.
Output devices: To disseminate data and information.
Storage devices: For data and information retention.
