What is the difference between segmentation and paging?

Calculate the $8-$bit twos complement representation of the following integer numbers $-11,103,$ and $-32.$ Include your computations. Do not give just the results.

$($a$)-11$

$($b$)101$

$($c$)-32$

Using $8-$bit twos complement arithmetic, calculate the following differences. First calculate the negative value of the subtrahend, then add this to the minuend.

$($a$)(01011000{)}_2-(00110100{)}_2$

$($b$)(11000101{)}_2-(11101110{)}_2$

Express the following numbers in IEEE $32-$bit floating point format. Give the bit patterns for the sign, exponent and fractional part:

$($a$)+2\mathrm{.}25$

$($b$)-0\mathrm{.}1875$

$($c$)-3\mathrm{.}5$

What is the decimal value of the following IEEE $32-$bit floating point numbers:

$($a$)01000010010100000000000000000000$

$($b$)10111110111000000000000000000000$

Construct the truth table for the following Boolean expressions:

$($a$)\frac{?}{\text{b}\text{a}\text{r}}(A)BC+\frac{A}{b}ar(B)C$

$($b$)A((\frac{?}{\text{b}\text{a}\text{r}}(B))C^{}\frac{+}{b}ar(B)C)$

$($c$)(P+Q)(P+R)(\frac{?}{\text{b}\text{a}\text{r}}(P)\frac{+}{b}ar(Q))$
