A Joystick is a control device that is connected to the computer to play games. A joystick is similar in structure to a control stick used by pilots in airplanes and got its name from the same. A joystick contains a stick, base, extra buttons, auto switch fire, trigger, throttle, POV hat, and a suction cup. A joystick also serves the purpose of assistive technology.
The device which can not be used in MS Office is a joystick. Therefore, option A is correct.
Answer:
For question a, it simplifies. If you re-express it in boolean algebra, you get:
(a + b) + (!a + b)
= a + !a + b
= b
So you can simplify that circuit to just:
x = 1 if b = 1
(edit: or rather, x = b)
For question b, let's try it:
(!a!b)(!b + c)
= !a!b + !a!bc
= !a!b(1 + c)
= !a!b
So that one can be simplified to
a = 0 and b = 0
I have no good means of drawing them here, but hopefully the simplification helped!
