1COMPUTER ORGANIZATION AND ARCHITECTUREQ1.A Computer uses IEEE-754single precision format to represent floatingpoints. What value (in decimal) the computer represents if the floating point isrepresented using the following binary digits:0 01111110 10100000000000000000000Answer:A) Single precision in IEEE 754 format is 0 0111111010100000000000000000000S=0thus it is a positive number01111110 =126E = 126-127=-1d=1.10100000000000000000000 x 2^-1= 0.110100000000000000000000 x 2^-1 x 2 ^1=0.110100000000000000000000=0.5+0.25+0.0625=0.8125The decimal value of the binary number is 8.125 * 10^-1sB)Let the 5 bit word be 00110
