Simile
A simile was a figure of speech that directly comparing one thing to another, explicitly drew a connection between two different things with the words "as" or "like". 

Discussing the interruption in the  sensors caused by the red bursts detected in 2257, Commander Michael Burnham described the interruption as "like a compass at the north pole." Evan Connolly indicated he found the "metaphor" simplistic, though Burnham corrected him that her statement was more accurately described as a simile. Captain Christopher Pike admired her correction, noting: "He said you were smart." ()
