Configuration refers to the arrangement or setup of components within a system, device, or software. It involves selecting and organizing various elements to ensure they work together effectively. For example, in a computer, configuration might include settings for hardware components like the CPU and RAM, as well as software settings for the operating system. In the context of networking, configuration is crucial for establishing connections between devices. This can involve setting up routers, switches, and firewalls to manage data flow and security. Proper configuration ensures that systems operate efficiently and meet the specific needs of users or organizations.
