Agent
An agent is defined as an entity that perceives and acts upon its environment. The term ‘agent’ can refer to both software agents and human agents.
A software agent is a computer program that is designed to autonomously perform tasks on behalf of its users. Software agents are often used to automate repetitive or tedious tasks, such as checking email or monitoring stock prices.
Human agents are individuals who act on behalf of others. Human agents can be found in a variety of industries, including real estate, sales, and customer service. Agents typically receive a commission for their services.
