Q1:

1) Form the two's complement of a unsigned hexadecimal number

hex to bin, bin to 2's, 2's to hex

Convert: -(A7)₁₆

1) Convert signed binary to decimal

2's - 1 , !bits , val = - (bin to dec):

Convert: (11011011)₂

2) Convert signed decimal to binary dec to bin , bin to 2's

Convert: (-391)₁₀

3) Convert signed decimal to hexadecimal dec to 2's , 2's to hex

Convert: (-543)₁₀

4) Convert signed hexadecimal to decimal

hex to bin (2's) , 2's -1 , !bits , val = - (bin to dec)

Convert: (A01)₁₆

Q2:

1) (10111)₂ + (111)₂ = ( )2
2) (101)₂ + (101)₁₀= ( )16
3) (-83)₁₀- (200)₁₆ = ( )rs
4) (ABC)₁₆ + (CBA)₁₆ = )16
5) (ABC)₁₆ - (CBA)₁₆ to = )2's

Q3:

1) Given a computer system with an old CPU that has only 16 bits for a RAM address, if RAM is allowed to save unsigned integer numbers, what is the maximum size in Bytes for this RAM.

RAM = 2^16 = 65536 B or 64 KB

2) Given a modern CPU installed along a RAM of 4GB, compute number of lines of the address bus connecting the RAM and the CPU?

4GB = 2^32 -> need 32 bit/line address bus
