Introduction to Boolean Algebra Boolean algebra was developed by George Boole in 1854. He developed an algebra that was used for designing logic circuits in computer system. According to George Boole symbols can be used to represent the structure of logic in computer arithmetic. It also deals with law or rules that’s why it is also known as laws of Boolean algebra. It is used to simplify Boolean expressions which represent combinational logic circuits in computer system. The law of Boolean algebra is used to reduce and simplify a complex Boolean expression and reduce the number of gates required. The variables used in Boolean algebra have truth values such as true and false and logic values such as logic 0 and logic 1. It used with binary operation such as multiplication (.), addition (+) and unary operation (‘) . There are various types of laws of Boolean...

## Logic Family and its types

Introduction to Logic family In logic family the switching characteristics of the semiconductor device such as diode, CMOS, transistor and MOSFET all are involve in the operation of digital circuit. There are various types of digital circuit are combined in a single chip or integrated circuit known as digital Integrated circuits or Digital Ics. The Digital Integrated circuits are required to make digital system or whole system. The term Integrated circuits means electronic circuit constructed on a single chip by use of such type of semiconductor devices and group of circuit give specific circuit called logic family. The Integrated circuit has small size and it is more reliable, inexpensive than other circuits. Logic family is defined in one line that circuit arrangement or configuration of circuit element in a special manner is called logic family. Types of Logic Family The logic family can be classified...

## Flip Flop and its Types

Introduction to Flip Flop A flip flop can be defined as a circuit capable of storing one bit of information either 1 or 0 based on inputs applied on it. The basic memory element used to store one bit of information in sequential circuit known as flip flop. It is also known as latch, bistable multivibrator and toggle circuit. Flip flop has logic 0 and 1 as two stable states. Clock is basically used to control flip flops. It can be classified into two categories: Positive Clocking Negative Clocking Positive Clocking If flip flop changes its state at high clock pulse then flip flop is said to have positive clocking. Negative Clocking If flip flop changes its state based on applied input then flip flop is said to have negative clocking. Features of flip flop A flip flop has number...

## Number System in Memory

Introduction to Number System The computer can understand binary number and when we type some letter or words the computer translates them in number. A computer can understand positional number system where there are only a few symbols called digits and these symbols represent different values depending on the position they occupy in the number. Each digit in a number can be represented by using Digit Position of digit in number Base of number system where base is defined as total number of digits Here are some number systems are as follows: Decimal number system Binary number system Octal number system Hexadecimal number system Decimal number system This number system is used in day to day life and consists of ten digits from 0 to 9 and use base 10. These digits are used to represent any numeric value it is mostly used in number system....
