The correct answer is: C. Neural network computers.
Neural network computers are computers that are modeled after the human brain. They are made up of many small processors, called neurons, that are connected to each other in a complex network. This network allows the computer to learn and adapt, just like the human brain.
Intelligent computers are computers that are able to perform tasks that would normally require human intelligence, such as understanding natural language and solving complex problems. Supercomputers are computers that are very powerful and can perform calculations very quickly. Smart computers are computers that are designed to be easy to use and understand.
Neural network computers are still in their early stages of development, but they have the potential to revolutionize the way we interact with computers. They could be used to create computers that are able to understand our natural language, recognize our faces, and even predict our actions.
