A VPN (Virtual Private Network) is the technology that allows a home PC to connect securely to a company's network over the internet. It extends a private network across a public network, enabling users to send and receive data as if their computing devices were directly connected to the private network. This makes VPNs ideal for remote work and accessing company resources securely from a home PC.
