Consider a $32-$bit hexadecimal number stored in memory as follows:

Address $100101102103$ Value $2$A C$2081$B

$8$

a$)$If the machine is big endian and uses $2$s complement representation for integers, write the $32-$bit integer stored at address $100($you may write the number in hex.$)$

b$)$If the machine is big endian and the number is an IEEE single$-$precision floating$-$point value, is the number positive or negative?

c$)$IfthemachineisbigendianandthenumberisanIEEEsingle$-$precisionfloatingpointvalue, determine the decimal equivalent of the number stored at address $100($you may leave your answer in scientific notation form, as a number times a power of $2).$

d$)$If the machine is little endian and uses $2$s complement representation for integers, write the $32-$bit integer stored at address $100($you may write the number in hex.$)$

e$)$If the machine is little endian and the number is an IEEE single$-$precision floating$-$point value, is the number positive or negative?

f$)$If the machine is little endian and the number is an IEEE single$-$precision floatingpoint value, determine the decimal equivalent of the number stored at address $100($you may leave your answer in scientific notation form, as a number times a power of $2).$
