1. If A=11001011 and B=10101110 then, what is the value of following operations ( F in hex =1111)
\n" ); document.write( "a. A AND B
\n" ); document.write( "

\r\n" );
document.write( "11001011 = CB\r\n" );
document.write( "10101110 = AE\r\n" );
document.write( "-----------------\r\n" );
document.write( "10001010 = 8A\r\n" );
document.write( "Both bits must be 1, or it's a zero.\r\n" );
document.write( "==========================\r\n" );
document.write( "b. A OR B\r\n" );

document.write( "------------\r\n" );
document.write( "11101111 = CF\r\n" );
document.write( "It either bit is a 1, the result is a 1.\r\n" );
