  4. Computer Science: In computer science, a domain can refer to a specific field of knowledge, influence, or activity. It can also refer to a set of network addresses or a group of computers that share a common communications address.
  5. Real Estate: In real estate, a domain can refer to a large and impressive estate or a territory over which rule or control is exercised.
  6. Business: In business, a domain can refer to a distinct subset of a company’s operations or market, such as a product domain or a service domain.
  7. Law: In legal terms, a domain can refer to the absolute ownership of land, or it can refer to a sphere of activity, knowledge, or influence.
  8. Artificial Intelligence: In AI, a domain refers to a specific area of knowledge or expertise that an AI system is designed to handle, such as medical diagnosis, language translation, or autonomous driving.
