A more thorough explanation:

An electronic agent is any computer program or automated system that can perform actions or respond to messages without human intervention. This means that the electronic agent can work independently and make decisions on its own.

• Chatbots: These are computer programs that can simulate conversation with human users. They can answer questions, provide information, and even make recommendations.
• Automated Trading Systems: These are computer programs that can buy and sell stocks or other financial instruments without human intervention. They use algorithms to analyze market data and make trading decisions.
• Virtual Assistants: These are computer programs that can perform tasks for users, such as scheduling appointments, sending emails, and setting reminders.

These examples illustrate the definition of electronic agents because they are all computer programs that can work independently and make decisions on their own. They do not require human intervention to perform their tasks.
