Foreground & Background
/ˈfɔːr.ɡraʊnd ənd ˈbæk.ɡraʊnd/
noun — “the multitasking traffic lanes of your computer — one lane for the VIP, one for everyone else.”
Foreground & Background describe the execution context of processes in an operating system. A Foreground process is the one currently interacting with the user, receiving input and displaying output directly. In contrast, Background processes run without direct user interaction, performing tasks like file indexing, updates, or system monitoring while the user focuses on other activities.
