Im not trying to cheat by asking others to help me in my homework...How many numbers can a 16-bit system represent? Show your working.

but i find this a really wierd question.

1) about what am i supposed to put as an answer?

2) why arent there any specifications to what base i am supposed to give the answer in? what should i assume?

3) why arent there any specifications to whether its signed or unsigned? what should i assume?

so which is the correct answer?

1)2)A 16-bit system can represent 65535_{1}₀ signed numbers.

The largest a 16-bit system can represent is 1111 1111 1111 1111₂

(then i do the calculations)3)A 16-bit system can represent 131071_{1}₀ unsigned numbers.

The largest a 16-bit system can represent is 1111 1111 1111 1111₂

(then i do the calculations)4)A 16-bitsystem can represent 1111 1111 1111 1111₂ Show your working part...... (i dont get what i supposed to do in this step)or what?
