An assign statement is a continuous assignment because the output is "recomputed" whenever any of its inputs change, forever, much like a simple logic gate. Unlike physical wires, wires (and other signals) in Verilog are directional.This means information flows in only one direction, from (usually one) source to the sinks (The source is also often called a driver that drives a value onto a wire). ; load: Loads shift register with data[3:0] instead of shifting.
