With remote access taking over distance and materials, accessing devices from faraway places is now a matter of the push of a button. You can now turn on computer remotely by activating a couple of options. In order to be able to access your system from a remote location, set up the option called Wake-On-Lane. Hit the Wake on Magic Packet to allow access from foreign devices. There you will need to put in the details of the accessing device so that your system does not get vulnerable to all attempts of access from malicious hackers. Another way you can access a computer from far away physical locations is through software called Team Viewer that allows access and monitor.
