Remote access to a computer system is typically facilitated by Remote Desktop Protocol (RDP) or Virtual Private Networks (VPNs). These technologies allow users to connect to systems from distant locations securely, enabling access to files, applications, and resources as if they were directly on the local network. RDP provides a graphical interface, while VPNs create a secure tunnel over the internet, ensuring that data transmitted is encrypted and private. Together, they enhance productivity and accessibility for remote workers and off-site collaborations.
