Data representation data types and number systems
What are the data types and number systems for data representation?
Types of data representation
Higher number systems are used in computing to reduce these streams of binary digits into manageable form.
This helps to improve the processing speed and optimize memory usage.
A number system is a set of symbols used to represent values derived from a common base or radix..
What is data types and data representation?
Data can be a name, a number, the colors in a photograph, or the notes in a musical composition.
Data Representation refers to the form in which data is stored, processed, and transmitted.
Devices such as smartphones, iPods, and computers store data in digital formats that can be handled by electronic circuitry..
What is data types and their representation?
It uses the binary number system to store data.
Each digit (0 or 1) is a bit thus the binary number 10110110 is a binary number having 8 bits.
The binary number system with only two independent digits, 0 and 1, is a base-2 number system.
All larger binary numbers are represented in terms of '0' and '1'..
What type of data is represented by numbers?
Quantitative Data
These kinds of data are also known as Numerical data.
It answers the questions like “how much,” “how many,” and “how often.” For example, the price of a phone, the computer's ram, the height or weight of a person, etc., falls under quantitative data..
Which form of data is used in number systems?

Each digit (0 or 1) is a bit thus the binary number 10110110 is a binary number having 8 bits.
The binary number system with only two independent digits, 0 and 1, is a base-2 number system.
All larger binary numbers are represented in terms of '0' and '1'..
- Computers use binary (base 2) number system, as they are made from binary digital components (known as transistors) operating in two states - on and off.
In computing, we also use hexadecimal (base 16) or octal (base 8) number systems, as a compact form for representing binary numbers.

What is a data type?
A data type defines what sorts of values can be stored and how that data can be used
The main data types are: Integer data can only store whole numbers - it will not store decimal places
The numbers can be positive (for example, 26) or negative (for example, -26) numbers
Boolean data can be in one of two states
In simple terms, for representing the information, we use the number system in the digital system. The digit value in the number system is calculated using: The digit The index, where the digit is present in the number. Finally, the base numbers, the total number of digits available in the number system.Numeric dataconsists of numbers that can be used in arithmetic operations. Digital devices represent numeric data using the binary number system, also called base 2. The binary number systemonly has two digits: 0 and 1. No numeral like 2 exists in the system, so the number “two” is represented in binary as 10 (pronounced “one zero”).To a computer, everything is a number, i.e., alphabets, pictures, sounds, etc., are numbers. Number system is categorized into four types − Binary number system consists of only two values, either 0 or 1 Octal number system represents values in 8 digits. Decimal number system represents values in 10 digits.
