1- How many bits are required to encode the value 240 as unsigned integer? How many as signed integer?

2- What is the 8-bit 2s complement binary code for -1? . What would it be as 16-bit 2s complement binary code?

3- True or False? We would double the range of signed integers that could be represented by 8 bits if we instead used 16 bits binary coding. Correct it if it is false!

4- True or False? The range of integers 0 to 127 would have the same binary codes if we encode them as 8-bit unsigned binary codes or as 8-bit 2s complement signed binary codes.
