Which program allows a user to invite a technician for remote computer repair?

The correct choice is Remote Assistance, which is specifically designed for scenarios where a user needs to invite a technician to help with remote computer repair. This feature enables the user to actively grant permission for the technician to connect to their computer and provides a way for the user to share their desktop screen. In this arrangement, the user can observe the technician's actions and communicate in real-time, ensuring that they understand any changes being made.

Remote Assistance is particularly user-friendly, as it generates an invitation that the user can send to the technician, allowing them to connect securely. This is different from Remote Desktop Connection, which typically requires the user to have administrative privileges or control over the machine being accessed and does not involve an invitation system as noted in Remote Assistance.

RDP, which stands for Remote Desktop Protocol, is a protocol that enables remote connections, but it is not a program in itself that allows an invitation for assistance. Meanwhile, remote connectivity is a broader term that encompasses any methods through which remote connections are established but does not identify a specific program like Remote Assistance does.
