Final answer:
A bot is a web-based program that employs artificial intelligence to perform automated tasks, such as searching the internet or interacting online. AI can vary from simple to highly complex systems, and despite debates on its capabilities, its applications are extensive in modern technology.
Step-by-step explanation:
The correct answer to the question is B. Bot. A bot, which is short for robot, is a web-based program that uses artificial intelligence (AI) techniques to automate tasks such as searches or interacting on social media platforms. To effectively define artificial intelligence, we can describe it as 'the simulation of human intelligence by machines programmed to mimic human thought and actions.'
There are different types of AI, including but not limited to reactive machines, limited memory, theory of mind, and self-aware AI. Each type serves different functions with varying complexities. AI technology ranges from the simple, like recommendation algorithms on entertainment platforms, to the highly complex, such as quantum computers or self-driving cars.
While strong AI attempts to replicate human cognitive abilities to perform multiple tasks, weak AI is designed to focus on a single task, such as virtual assistants like Apple's Siri. Despite varying assertions about the limits of AI, its presence and applications in our daily lives are undeniable and continue to advance.
