What are the distinctions between computers from the third generation and computers from the fourth generation?

Our investigation suggests that there may be a need for a further tier of classification in Flynn's taxonomy. How do today's computers improve upon their forebears? What features give current PCs an advantage over its analogous machines?

To what extent has the impact of computers and their applications been widespread thus far?

According to the findings of our study, Flynn's taxonomy has to be revised to include one additional level. Why are today's computers so much more advanced than those that came before them?
