Question: Which of the following computer generation uses concept of artificial intelligence?

Answer:

The concept of artificial intelligence (AI) was first introduced in the 5th generation of computers, which spanned the period from the mid-1980s to the early 1990s. The main focus of this generation was on the development of AI technologies and expert systems that could mimic human intelligence and decision-making capabilities.

The 5th generation of computers also saw the development of new programming languages and software tools that were designed to support AI applications. Some of the notable achievements of this generation included the development of advanced speech recognition systems, natural language processing, and computer vision technologies. However, it should be noted that AI technologies and concepts have continued to evolve and be refined in subsequent generations of computers as well.
