computer systems able to perform tasks that normally require human intelligence,

It seems like you're asking about the definition of a certain concept but your question got cut off. If you're referring to "computer systems able to perform tasks that normally require human intelligence," this is typically known as Artificial Intelligence (AI).

AI is a branch of computer science that aims to create systems capable of performing tasks that would normally require human intelligence. These tasks include learning and adapting to new information or tasks, understanding human language (natural language processing), recognizing patterns (such as in images or speech), problem-solving, and decision-making.

AI can be categorized into two types: Narrow AI, which is designed to perform a narrow task (e.g., facial recognition or internet searches), and General AI, which can perform any intellectual task that a human being can do.

AI technologies are now commonly used in a wide range of fields, including but not limited to healthcare, finance, transportation, and entertainment.
