Explanation / Answer

Firstly, I'm assuming you only want the answer to questions 6 and 7 since the question above 6 is not fully visible.

Alright, so Q.6 first.

In order to convert a decimal number into binary 2's complement. We take the positive part of the decimal number, convert it to binary and then flip all the bits and then add 1.

So, to do the reverse we need to basically do the process backwards.

But, to do this faster you can just take the rightmost bit as negative decimal equivalent and calculate the decimal value of the binary number normally.

Which means 10110 would be -(24) + 22 + 21 = -16 + 4 + 2 = -10 which gives the same answer.

Now to Q.7:

The message is 47 4F 4F 44 20 4A 4F 42, now you must be wondering why I wrote it in pairs. It is because in the question it's given that the English character is in 1 byte and 2 hexadecimal digits make up 1 byte, which basically means that each of these pairs is a 1 byte character.

To get the ASCII value, we need to convert each hexadecimal pair into decimal value. You can do this by multiplying the digit with increasing powers of 16 from right to left.

So, 47 in hex = 4*(161) + 7*(160) = 64 + 7 = 71

Similarly 4F in hex = 4*(161) + 15*(160) = 64 + 15 = 79 (Remember A = 10, B = 11 ...... F = 15 for hexadecimals)

So the whole message is now 71 79 79 68 32 74 79 66. Now in ASCII, 'A' is for 65, 'B' for 66 and so on.. and 32 is for empty space character ' '.

Hence, the message then becomes 'G' 'O' 'O' 'D' ' ' 'J' 'O' 'B'. Which is the answer => "GOOD JOB".

Hope this helps.
