These intelligent machines are programmed to understand and respond to natural language, making them capable of carrying out tasks and providing information in a conversational manner. Bots can be found in various forms, from chatbots on messaging platforms to virtual assistants on smart devices. They are constantly evolving and improving, with the goal of providing seamless and efficient communication between humans and machines.
