# Online Random Number Generator

Last Updated : 20 Mar, 2024

Random Number Generator is a simple online tool used to generate random numbers between any two given numbers. Generate random positives with or without repeats within a custom range from 0 to 99999.

This Random Number Generator is Easy to use and accurate, which can be used for a lot of fun activities.

The Random Number Generator is a free online tool that can be used in many works such as in random toss, and playing guesstimates. For instance, you want to generate a random number b/w 10 – 80 or 133 – 57799 depending upon your need. then you just simply follow the given step.

## How to Generate Random Numbers

Here is the step-by-step guide to generating numbers using this online tool.

• Step 1: first define a range from which you want to specify the article.
• Step 2: Enter the lower limit in the left box, and the upper limit in the right box.
• Step 3: Enter the “Generate” Button.
• Step 4: Direct Copy your Results. (Optional)

## Types of Random Number Generator

Random number generators can be categorized into two types – hardware-based and pseudo-random number generators. Hardware-based random-number generators can use devices like dice, coins, or other similar objects.

On the other hand, a pseudo-random number generator is an algorithm that generates a sequence of numbers that has properties similar to sequences of random numbers. However, the numbers generated by pseudo-random number generators are not truly random.

Similarly, the generators mentioned above are also pseudo-random number generators. Although the numbers generated by these generators are sufficient for most applications, they are not suitable for cryptographic purposes. True random numbers are generated by physical phenomena such as atmospheric noise, thermal noise, and other quantum phenomena. The methods used to generate true random numbers also need to compensate for potential biases caused by the measurement process.

## Why Online Random Number Generator?

As the technology grows, Hardware-based random-number generators can involve the use of a dice, a coin for flipping, or many other devices have been replaced with online computer program-based Tools which are more convenient, free, flexible and easy to use.

Same, This Random Number Generator we use above is also a computer-based program based on a pseudo-centric algorithm which is more convenient then old hardware based tools.
