## Introductions :

If you are a competitive exams addict and are looking forward to cracking exams of **RBI, SBI, IBPS, SSB, and other State exams**, Go ahead reading; Because, This is a perfect article for peeps like you with bigger goals. For this time, we will be thoroughly discussing **Data Representations Questions and Answers**. Before that, we will be **discussing important points **about the same. But first, If you are here with a reason you will definitely know what is the essentiality of further matter. However, if you are new, we’ll let you know the importance. Just **don’t worry and scroll further**. There’s lots more to **explore**.

## What Is Data Representation?

**Answer**: **Data is a Technical word for information**. Likewise, Wikipedia says, “**Data are individual facts, statistics, or items of information, often numeric**. **One collects them via long and Short term research**“. In other words, Data is a collection of Numerical and Condition values of any circumstance. On the other hand, Datum is its single component.

The **raw form of data** is not orthodox for understanding Concepts. However, the conversion of this data into graphs, tables, diagram images makes it easy to understand. This conversion is nothing but **Data Representations**.

For example, A thermometer reading from an outdoor Arctic location recording a tropical temperature. Observers then convert this reading into a table for further visualization.

## Types Of Data:

**Decimal Number System**: Decimal Number System AKA Hindu-Arabic number system is a positional number system working 10 as the base. Accordingly, It requires 10 different numerals. In addition, it requires a Decimal point to show Decimal fractions.

**Binary Number System**: Binary Number System is a positional number system working 2 as the base. Firstly, It is a two-method mathematical system that uses only two symbols; typically 0 and 1. Secondly, The base-2 numeral system is a positional notation with a radix of 2.

**Octal Number System**: Octal Number system AKA Oct are positional number system working 8 as the base. It uses digits 0 to 7, that is to say, 10 uses 8 as Decimal, and 100 uses 64 as Decimal.

**Hexadecimal Number System**: Hexadecimal Number System is a positional number system working 16 as the base. This number system, therefore, has numbers from 0 to 15. A single unit should represent the two-digit as a result for them to exist in the numeral system.

To sum up the explanations, we begin the Questions. So, Let’s dig into Data Representation Questions and Answers.
