Answer: hello your question lacks the required option, below are the missing options
A. The transaction data in the tampered block is deleted, and a copy is created with the same hash value.
B. The hash values of transaction data of subsequent blocks are validated, and the chain is broken.
C. The hash value for the entire block is nullified, creating a domino effect on all subsequent blocks.
D. The hash values of subsequent blocks are updated as soon as they are tampered with, and the chain continues.
answer : The hash values of subsequent blocks are updated as soon as they are tampered with, and the chain continues ( D )
Explanation:
What happens if a transaction data is changed in an earlier existing block in a Blockchain is that the Hash values of subsequent blocks will be updated as soon as they are tampered with and the chain will continue.
Blockchain is a specially design system for recording information, hence any change in data inputted in an earlier existing blocks that changes will automatically be updated as well in all preceding blocks.
Answer:
See attachment for flowchart
Explanation:
The flowchart is represented by the following algorithm:
1. Start
2. Input Mass
3. Input Volume
4 Density = Mass/Volume
5. Print Density
6. Stop
The flowchart is explained by the algorithm above.
It starts by accepting input for Mass
Then it accepts input for Volume
Step 4 of the flowchart/algorithm calculated the Density using the following formula: Density = Mass/Volume
Step 5 prints the calculated Density
The flowchart stops execution afterwards
Note that the flowchart assumes that the user input is of number type (integer, float, double, etc.)
"Key logger" This could be software or hardware that does this.
This depends on what program you're using. Some programs can only read certain files exclusive to that program, such as .psd files can usually only be read in Photoshop or other adobe programs. Many fields of work (Journalism, the Arts, Design, etc.) ask for .psd files to be converted to either .png, .jpg, or .tiff so that it can be seen on many other platforms.
For images especially, files are more compatible either on a program or printed. for example, .png files are good for storing color data from computer to computer, but if you print a .png file, the quality is poor. hence it's recommended to save files you want to print for designs as .jpeg, because .jpeg can more easily be printed and will then be presented at a high quality.
Sometimes color quality changes depending on CMYK as well but that's a whole other ball of wax.
