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.
A computer is made up of different network. The setting that molly must change is network type.
A computer network is known to be a group of computers that are linked to each other so as to help the computer to communicate with another computer and share their resources, data, and applications.
A computer network can be classified based on their sizes. A computer network is of four types. They are:
- PAN(Personal Area Network)
- MAN(Metropolitan Area Network)
