#### Answers

 181 Answer :   (b) Reason :            The first computer architecture having stored program is Von-Neumann 182 Answer :   (c) Reason :            Large-scale integrated and very large-scale integrated circuits are used  in the IV generation. 183 Answer :   (a) Reason :            The x value is 01000011 184 Answer :   (c) Reason :            The gray code of 1001 is 1101 185 Answer :   (a) Reason :            Over –flow flag will be set . 186 Answer :   (a) Reason :            The binary adder is used to add binary numbers of any length 187 Answer :   (d) Reason :            Unsigned binary representation occupies less space to store the number +255. 188 Answer :   (e) Reason :            If 2n data inputs lines are connected to a MUX then there will be n Selection lines.                  For  8-to -1 MUX 23 input lines and 3 selection lines are possible 189 Answer :   (d) Reason :            The complement of AB’ +C’D is ( A’+B ) ( C+D’ ) 190 Answer :   (b) Reason :            Shift registers are used for serial to parallel data. Conversion.

2. If you need your ex-girlfriend or ex-boyfriend to come crawling back to you on their knees (even if they're dating somebody else now) you have to watch this video
right away...

(VIDEO) Have your ex CRAWLING back to you...?
