answer and explain please

Write the 8-bit-bman two's-complement representation of the following numbers. Show the steps of converting the number. A) 64_10 B) -128_10 C) 2_10 D) 128_10 Convert the following 16-bit Hexadecimal number to decimal, assuming they are signed numbers. I recommend converting them to binary and then converting the signed binary to decimal. A) 0xffff B) 1250_14 C) 0x0011 D) 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 0x0055 at the start of each line. A) Port & = 0xfff0: B) Port l = 15: // 15 is decimal. C) Port = Port ^0x0005: D) Port = ((Port & ~(0x000f))|0x0020)
