On the same pattern, communication with computers is carried out through a language. This language is understood both by user and the machine. Just as every language like English, Hindi has its grammatical rules; every computer language is bound by rules known as SYNTAX of that language. The user is bound by that syntax while communicating with the computer system.                                                                                     ...

vv Logic gates: A logic circuit the outputs depends upon the inputs according to some logic rules. Types of logic gates: ð   Basic gates/Primary/Fundamental (AND, OR, NOT, BUFFER) ð   Compound gates (NAND, NOR, XOR, XNOR) vv Universal Gate: A gate that can perform all the basic logical operation is called Universal Gate. NAND, NOR gates are Universal Gate. ¯¯ Middle of 19 th century, an English mathematician George Boole developed rules for manipulations of binary variables, known as Boolean algebra.ion. vv Sign-Magnitude Representation: Digital circuit understands only two symbol 0 and 1.Thus those are used to indicate the sign of a number. Normally an additional bit is used as the sign bit and it is placed at the most significant bit (MSB) location. A 0 is used to a positive number and A 1 is used to a negative number. This kind of representation is called a Sign –Magnitude –Representation. vv Bipolar Junction transistor:  A Bipolar Junction trans...
