A private network is a communication network that is restricted to a specific group of users or devices. Unlike public networks, which are open to anyone, private networks provide enhanced security and control over data. They are commonly used by businesses and organizations to protect sensitive information and ensure that only authorized personnel can access certain resources. Private networks can be set up using various technologies, such as Virtual Private Networks (VPNs) or Local Area Networks (LANs). These networks allow users to share files, applications, and other resources securely. By limiting access, private networks help prevent unauthorized use and potential cyber threats.
