Total $15$ points

$(1$ point$)$ Why is assembly language not usually used when writing large application programs?

$(1$ point$)$ Assume that you have three $8-$bit storages $($memory$)$ named $A,B,$ and $C$ to store binary numbers. Memory A contains $11110100$ and memory B contains $10110111.$ Compute A$+$B and store the value in C register. What is the content of register, $C$ after the computation? Show the computation in details with carries.

$(2$ points$)$ Assume that you have $4-$bit storage to store the numbers. Calculate the following operations using two's complement method. Show all the computations in details. $($assuming $4-$bit register is used$)$

$-3-1-1$

$[$Hint: Perform the computation in binary system, then convert it back to decimal$]$

$4.(1$ point$)$ What is the hexadecimal representation of the following binary numbers? Show the conversion in details.

$100010100101010111100001100110111$

$(2$ points$)$ What is the $16-$bit hexadecimal representation of the following signed decimal integer? Show all the steps of conversion in details.

$-58$

$(2$ points$)$ What is the decimal representation of each of the following signed binary numbers? Show the computation.

a$.(1$ point$)01110111$

b$.(1$ point$)11110001$

$(2$ point$)$ Evaluate the following Hexadecimal expression. All the numbers are hexadecimal. Show all the steps of computation and the carries.
