Today every student of science or engineering and even high school students come across this common word electronics. Students study just because it is part of academics, but some students at least 1 out of every 10 students wonder?

## Introduction & Importance of Digital electronics

Today, We will begin with a short introduction to digital electronics and learn more about analog and digital circuits in future posts. Before we get started with the formal introduction, I think some questions would have already started running through your mind. Alright, I will put down the question in a better way.

## Number Systems

A number system is simply a methodology that includes rules and symbols for counting, or performing operations like addition, subtraction, multiplication, division.

## Binary to Decimal – How to Convert Binary to Decimal with examples

Convert Binary to Decimal number step-by-step explanation with illustrated examples

In earlier posts, we have covered the various number systems and their representation. Here we will see how we can convert a given binary number to its equivalent in another number system(Decimal number)

## Octal to Decimal – How to convert octal to Decimal

This post we will learn **how to convert octal to decimal** with Illustrated examples showing the conversion steps from a given octal number to an equivalent decimal number.

## Hex to Decimal – Hex to Decimal Converter

We can convert hexadecimal to decimal by simply representing the given each digit of the given Hexadecimal number as sum of powers of 16, since for hexadecimal number system 16 is the base or radix. Here we first convert each individual hexadecimal digit separately and then add it together to get the final decimal equivalent. Detailed steps explaining the process of converting Hexadecimal to decimal, with illustrated examples of hexadecimal to decimal conversions.

## Number System Conversion

In the previous posts, we have discussed the representation of numbers in different number systems. We have also solved example problems step by step and tried some shortcuts as well. Here we will briefly discuss number system conversion. In other words, we would see how we can represent a given number in another number system without any change in value.

## Decimal vs Binary – What are the Similarities & differences between Binary & Decimal Systems?

In this post, we will do a quick comparison of decimal vs binary number systems, highlighting all the similarities and differences between the two number systems for better understanding of their use case.

We are familiar with the decimal number system or the decimal numeration system since we use it every day for paying bills, grocery shopping, bank transactions, etc.,. In the decimal number system, we represent or express a given decimal number in Units, tens, hundreds, thousands, etc.,

On the other hand, our computers and other digital devices which we use every day make use of the binary number system to communicate, perform arithmetic and logical operations.

The decimal number uses 10 digits to represent different values whereas the Binary number uses only 2 digits (0 & 1) to represent any binary number.

## Hexadecimal vs Decimal – Difference between Hexadecimal and decimal numbers

In earlier posts, we have been discussing the representation of both hexadecimal & decimal numbers. In this post, we will be listing out the difference between hexadecimal and decimal numbers.

## Octal vs Decimal

We aware of the octal number system which uses 8 digits to represent all the numbers and the decimal number system which uses 10 digits to represent all the numbers include fractions.

We will now see the difference between octal and decimal numbers.
