COMPUTER LANGUAGES Languages are a means of communication. Normally people interact with each other through a language. 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.                                                                                     ...

a.                    Microcomputers (Personal Computer)  A microcomputer is the smallest general purpose processing system. The older pc started 8 bit processor with speed of 3.7MB and current pc 64 bit processor with speed  of 4.66 GB.  Examples: -      IBM PC s,  APPLE  computers Microcomputer can be classified into 2 types :            1 .   Desktops            2. Portables The difference is portables can be used while travelling whereas desktops computers cannot be carried around. The different portable computers are: - 1)         Laptop 2)         Notebooks 3)         Palmtop (hand held) 4)         Wearable ...

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...
