What is agent

An agent is a software application or robotic device that can act on behalf of a user or other program to complete tasks, interact with other systems and environments, and provide services. Agents are used in a wide variety of applications, from customer service to automation of complex tasks. Agents can be intelligent, meaning they have the ability to learn and adapt to changing conditions, or they can be programmed to follow a set of rules and instructions. Agents can be used to automate mundane tasks, such as scheduling appointments, or to provide more complex services, such as recommending products or services. Agents can also be used to monitor and control systems, such as surveillance cameras or industrial machines.
