The use of atomic weapons at the end of World War 2 fostered fears about their potential use during the Cold War years.
Interrupts and signals are low-level mechanisms that can alter the flow of control in a way similar to a subroutine, but usually occur as a response to some external stimulus or event (that can occur asynchronously), rather than execution of an 'in-line' control flow statement.
Steady uniform flow is defined by two factors. 1  Uniform flow, a flow in which the velocity pattern within a cross-section in the direction of flow does not change from one section to another with distance. 2  Steady flow, a flow in which the velocity at any point in the channel does not change with time.
