Logic

/ˌkɑːmbɪˈneɪʃənəl ˈsɜːrkɪt/

noun … “Logic circuit with output determined only by current inputs.”

Combinational Circuit is a type of digital logic circuit whose output depends solely on the present values of its inputs, with no reliance on past states or stored memory. Unlike sequential circuits, combinational circuits have no internal state, clock, or feedback loops. They are built entirely from logic gates and implement Boolean expressions directly.
