Final answer:
Moving to a new chat room doesn't give a suspicious person access to your computer, unless you engage in unsafe actions like downloading harmful software or sharing sensitive information.
Step-by-step explanation:
If you meet a suspicious person in a chat room, moving to a new chat room does not inherently give them access to your computer. Access to your computer generally requires downloading and installing malicious software, clicking on a dangerous link, or providing personal information that can be used to compromise your system. Simply participating in a chat room does not expose you to these risks unless you perform an action that compromises your security.
