Write the 8-bit binary two's-complement representation of the following numbers. Show the steps of converting the number. 100_10 -128_10 5_10 128_10 Convert the following 16-bit Hexadecimal number to decimal, assuming they are unsigned numbers. I recommend converting them to binary and then converting binary to decimal. 0 times ffff 1250_16 0 times 0011 55AA_16 Write out the results of the following logical operations, assuming the variables are all int's (16-bit integers). Also assume that the variable "Port" is equal to 0 times 0055 for each line. Port &= 0 times fff0; Port = 15; Port = Port^0 times 0005; Port = ((Port & (0 times 000f)) | 0 times 0020)
