The correct answer is D. All of the above.
Fifth generation computers are likely to exhibit artificial intelligence, heuristic behavior, and advanced parallel processing.
Artificial intelligence (AI) is the ability of a computer or machine to mimic the capabilities of a human brain. This includes the ability to learn, reason, and solve problems. AI is already being used in a variety of applications, such as self-driving cars, facial recognition software, and medical diagnosis.
Heuristic behavior is a type of problem-solving that relies on trial and error. Heuristics are rules of thumb that can be used to quickly find a solution to a problem, even if it is not the best possible solution. Heuristic behavior is often used in situations where there is a lot of uncertainty or where there is not enough time to find the optimal solution.
Advanced parallel processing is the ability to perform multiple tasks at the same time. This is done by dividing the tasks into smaller pieces and then processing them on multiple processors. Advanced parallel processing is essential for many applications, such as video games, weather forecasting, and scientific computing.
In conclusion, fifth generation computers are likely to exhibit artificial intelligence, heuristic behavior, and advanced parallel processing. These capabilities will allow them to perform tasks that are currently beyond the capabilities of current computers.
