Answer:
The answer is "Option a, and c".
Explanation:
Following are the description of the Digital Signature choices:
- To change the physical transportation of paper or link files in the computerized messaging system, some processes should be identified and utilized in digital signatures, which enables documentation to be validated unforgivably.
- Using public-key cryptography, digital signatures, that's an exquisite system, that's why options a and b are correct.
- Digital signatures are not a central authority, that's why the option B is wrong.
Answer:
true
Explanation:
The command:
find -empty -type f -exec rm { } \;
carries out the following steps.
1) Finds all the empty files in the current directory and its subdirectories.
2) For each of the identified files, it executes the command specified as the parameter to exec option,namely, rm <filename>.
So effectively it removes all empty files in the directory tree starting at the current directory.
<u>Answer:</u>
<u>Privacy concerns.</u>
<u>Explanation:</u>
Privacy concerns have played an important role in how we collect digital data. For example, privacy activists believe that an individual has the right to know how his or her information is being used and that such an individual also has the right to withhold such information.
Such issues have affected the ability of law enforcement agencies to investigate criminal activities. For example, an individual who is accused of a crime may claim a <em>right to withhold his personal information, such as his mobile device, and thus he refuses to give out such information.</em>
Answer:
b. typically contain more circuits in the network than in star or ring networks
Explanation:
In mesh architecture, all computers are connected to each other. In mesh all nodes connect directly and non hierarchical to each other so as to efficiently route data.
Mesh combines the benefits of both ring and star networks. It usually provide relatively short routes through the network (compared to ring networks) and provide many possible routes through the network to prevent one circuit from becoming overloaded (as compared to star network). Mesh network uses decentralized routing with each network performing its own routing.
Mesh network typically contain more circuits in the network than in star or ring networks and are more expensive than ring networks
