Answer:
The main problem with such a tool would be resource usage
Explanation:
The main problem with such a tool would be resource usage. Such a tool would need a large amount of CPU power in order to check all of the files on the system thoroughly and at a fast enough speed to finish the process before the next cycle starts. Such a program would also have to allocate a large amount of hard drive space since it would need to temporarily save the original versions of these files in order to compare the current file to the original version and determine whether it changed or not. Depending the amount of files in the system the work on configuring the program may be very extensive since each individual file needs to be analyzed to determine whether or not they need to be verified by the program or not. Monitoring responses may not be so time consuming since the program should only warn about changes that have occurred which may be only 10% of the files on a daily basis or less.
Answer:
D. Mass production
Explanation:
Henry Ford came up with the first assembly line for the production of cars. It was his aim to be able to produce enough cars to meet the high demands. With the assembly line, he was able to produce automobiles more efficiently, lessening the time substantially, to produce a single automobile.
This allowed them to not only produce more automobiles, but also allowed him to maintain the low cost of the car. Being able to produce more automobiles also enabled him to increase his worker's wages.
