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:
Option D, This PC allows a user to save a presentation on a computer
Explanation:
If one choses the option C, the file will be saved in the folder in which the user is working. Hence, option C is incorrect.
Like wise option A is also incorrect as it will require user to provide a location as option for saving the file
Option B is also incorrect as it will allow the user to save files in the C drive/D drive or one drive
Option D is correct because if the user choses this option file will be saved on the computer.
Hence option D is correct
Answer:
Option E Components that interact to produce information
Explanation:
Information system is a system to collect, analyze and disseminate information. An information system consists of five components that work with each other to produce information:
- Computer hardware - physical machine that works with information
- Computer software - a set of computer instructions that tell computer hardware how to perform a task
- Telecommunications - components that connect a group of hardware as to establish a network. This usually includes WiFI technology.
- Databases and data warehouses - the place where the digital data are kept and retrieved.
- Human resources and procedures - human expertise that run the system by following some standard procedures.
Answer:
A linear search is one that scans every record/file until it discovers the value being searched for.
Binary search, on the other hand, is also known as <em>Logarithmic search</em>. It is used to locate the position of a value inside an array that has already been sorted.
The linear search will return the lowest value faster than the binary search when small arrays are involved.
This will only be feasible when the array is sorted prior.
Cheers!
