263.  George Boole find the relationship between Logic & Math's in 1854; 264.  George Boole invented the Boolean Algebra; 265.  There are 2 values of each variable in Boolean Algebra; 266.  There are 3 basic/fundamental gates in Boolean Algebra; 267.  NOT is one of the basic/fundamental gates of Boolean Algebra; 268.  The logic gate NOT has one input and one output; 269.  NOT operator is one of the logical operator; 270.  The logic gate NOT has- One output & One Output; 271.  The main character of NOT gate is- reverse the signal; 272.  X-NOR gate is the combination of X-OR gate and NOT gate; 273.  John Nepiar invented- Logarithms; 274.  Super computers, Mainframe computers, minicomputers and Micro computers are based on Digital; 275.  The arranging of data in a logical sequence is called- sorting; 276.  The brain of a computer within the CPU is- Arithmetic Logic Unit (ALU); 277.  Central Processing Unit is combination of Arithmetic Logic Unit & Control Unit; 278.  The ancient Babylon people used 2 types of counting system; 279.  The ancient Babylon people used 15 based for large counting; 280.  The ancient Babylon people used 10 based for small counting; 281.  The ten-based book was published in India; 282.  Al Khwarizmi wrote a book on ten based; 283.  Binary number system is mainly used for computer system; 284.  In binary number system 2 is the base; 285.  In decimal system there are 10 digits; 286.  In number system the lowest unit is digit; 287.  Computers use 2 digits for its electronic job purpose: 0 & 1; 288.  1 (One) is the value of any number when its power zero;
