Question

The logical ______ of the endpoint codes determines if the line is completely inside the window.

(a) AND

(b) OR

(c) NOT

(d) NOR

Answer 1

Right choice is (b) OR

Easiest explanation: The logical OR of the endpoint codes determines if the line is completely inside the window. If the logical OR is zero, the line can be trivially accepted. For example, if the endpoint codes are 0000 and 0000, the logical OR is 0000 – the line can be trivially accepted.
