Socket Plugs

The assignment is a direct analogy with genitalia and heterosexual sex; the part bearing one or more protrusions, or which fits inside the other, being designated male in contrast to the part containing the corresponding indentations, or fitting outside the other, being designated female. Extension of the analogy results in the verb to mate being used to describe the process of connecting two corresponding parts together.though the names of some standards conflict with this as they contain the letters A or B within the name; unambiguous, though rare, terms include plug and socket or jack.
