Running Head: Computer Organization and Architecture3Question 1 a: Floating points representationA Computer uses IEEE-754 single precision format to represent floating points. What value (in decimal) the computer represents if the floating point is represented using the following binary digits: 0 01111110 10100000000000000000000Solution:01111110=126 Then, 126-127=-1 =1.10100000000000000000000 x 2^-1 = 0.110100000000000000000000 x 2^-1 x 2 ^1 =0.110100000000000000000000=0.5+0.25+0.0625=0.8125 Null & Lobur (2015).Question 1 b: Binary NumbersUsing a "word" of 5 bits, list all of the possible signed binary numbers and their decimal equivalents that are represent able in: [3+3+3 = 9 marks]i. Signed magnitudeii. One's complementiii. Two's complementSolution:According to Patterson & Hennessy, (2012) a word of 5 bits can be represented as:SignedMagnitudeOne’sComplementTwo’scomplementDecimalEquivalent00000000000000000000100001000011000100001000010200011000110001130010000100001004001010010100101500110001100011060011100111001117010000100001000801001010010100190101001010010101001011010110101111011000110001100120110101101011011301110011100111014
