D-Bus

D-Bus (Desktop Bus) is an inter-process communication system that enables different software applications and components on a computer to exchange messages and coordinate their actions. It acts as a central messaging hub, allowing programs to request services, send notifications, or share data without needing to know each other's internal details. By facilitating smooth communication between various parts of a system, D-Bus helps ensure that applications can work together efficiently and respond quickly to user inputs or system events, improving overall system stability and user experience.
