A number system is a set of symbols used to represent values derived from a common base or radix. In a number, the value of each digit can be determined using digit, position of the digit in the number, and the base of the number system. The base is defined as the total number of digits are available in the number system. This is known as positional number system.Number SystemBaseDigit UsedBinary20, 1Octal80, 1, 2, 3, 4, 5, 6, 7Decimal100, 1, 2, 3, 4, 5, 6, 7, 8, 9Hexadecimal160, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, ...

Light can be obtained from various sources like candles, lamp and sunrays etc. Light bulb had invented by Thomas Edison in 1879. An electric current is passed through a filament inside bulb, it gets heated up and emits light when sufficient current is passed through the filament. That means it converts electrical energy into heat energy in the bulb. Where in Light Emitting Diodes (LED), electronic electrical energy can directly converted into light energy.Light is a energy which is released by atoms. Particles of light are photons which have no mass. Atoms are basic building blocks which are made of small ... Read More

A Bipolar Junction Transistor (BJT) is a three terminal circuit or device that amplifies flow of current. It is solid state device that flows current in two terminals, i.e., collector and emitter and controlled by third device known as terminal or base terminal. Unlike a normal p-n junction diode, this transistor has two p-n junctions. The basic symbols of BJT are n-type and p-type. Electronic current is conducted by both free electrons and holes in bipolar junction transistor.Terminals of Bipolar Junction TransistorsThere are three terminals in bipolar junction transistors are explained below.Emitter − It supplies charge carriers. It is highly ... Read More

A microprocessor is digital is a digital circuit which is built using a combination logic functions. The microprocessor package contains an integrated circuit.Integrated CircuitAn integrated circuit is electronic circuit or device that has electronic components on a small semiconductor chip. It has functionality of logic AND or amplifying of a signal. These are mainly two types of circuits: Digital or Analog. Analog ICs handle continuous signals such as audio signals and Digital ICs handle discrete signals such as binary values.Types of Integrated CircuitsThere are different types of integrated circuits based various criteria. Based on intended application, the Integrated Circuit (IC) ... Read More

The impact of technology has been nothing short of phenomenal on the lives of people with disabilities. Nothing articulates this better than the statement by Mary Pat Radabaugh, Director of IBM National Support Center for Persons with Disabilities - "For most people, technology makes things easier.Technology Makes Things PossibleFor people with disabilities, technology makes things possible." That's one of the most accurate observations on the matter and it is based on a whole list of examples that could be found across different parts of the world. In fact, there's a term that has been coined specifically for this kind of ... Read More

Binary is the simplest kind of number system that uses only two digits of 0 and 1 (i.e. value of base 2). Since digital electronics have only these two states (either 0 or 1), so binary number is most preferred in modern computer engineer, networking and communication specialists, and other professionals.Whereas Hexadecimal number is one of the number systems which has value is 16 and it has only 16 symbols − 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 and A, B, C, D, E, F. Where A, B, C, D, E and F are single bit representations ... Read More

Whereas Hexadecimal number is one of the number systems which has value is 16 and it has only 16 symbols: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 and A, B, C, D, E, F. Where A, B, C, D, E and F are single bit representations of decimal value 10, 11, 12, 13, 14 and 15 respectively. Whereas Decimal system is most familiar number system to the general public. It is base 10 which has only 10 symbols: 0, 1, 2, 3, 4, 5, 6, 7, 8 and 9.Conversion from Hexadecimal to Decimal number systemThere are various ... Read More

Decimal system is most familiar number system to the general public. It is base 10 which has only 10 symbols − 0, 1, 2, 3, 4, 5, 6, 7, 8 and 9. Whereas Hexadecimal system is most familiar number system color representation in Computers or digital systems. It is base 16 which has only 16 symbols: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 and A, B, C, D, E, F. These A, B, C, D, E, F use as single digit in place of double digits, 10, 11, 12, 13, 14, 15 respectively.Conversion from Decimal to Hexadecimal ... Read More

Octal number is one of the number systems which has value of base is 8, that means there only 8 symbols − 0, 1, 2, 3, 4, 5, 6, and 7. Whereas Binary number is most familiar number system to the digital systems, networking, and computer professionals. It is base 2 which has only 2 symbols − 0 and 1, these digits can be represented by off and on respectively.Conversion from Octal to Binary number systemThere are various direct or indirect methods to convert a octal number into binary number. In an indirect method, you need to convert an octal ... Read More
