11. The weights are 8+0+2+1 = 11.

2^n distinct values, ranging from 0 to 2^n − 1 when unsigned.

255, since 2^8 − 1 = 255.

Group the bits into sets of three starting from the radix point; each group of three bits maps to one octal digit.

Group the bits into sets of four starting from the radix point; each group of four bits maps to one hex digit.
