RAC, or Remote Access Control, is a technology that allows users to manage and control devices or systems from a distance. This can include accessing computers, servers, or other networked devices over the internet. RAC is commonly used in various fields, including IT support, home automation, and security systems, enabling users to perform tasks without being physically present. In addition to its convenience, RAC enhances security by allowing users to monitor and control access to sensitive information or systems. It often employs encryption and authentication methods to ensure that only authorized individuals can gain access, making it a vital tool for both personal and professional use.
