    What are Random Numbers?
    A random number is a number chosen from a pool of numbers without any pre-defined criteria for choosing that particular number. If a series of random numbers are generated, they should be such that there is no discernible pattern defining the choice of those numbers. While generating random numbers, it should be impossible to predict an upcoming outcome based on the numbers generated in the past. Random numbers have various applications such as in the field of cryptography, statistical computation, simulation processes, etc.

    What is a Random Number Generator?
    A random number generator is a system or source capable of generating numbers without any identifiable pattern or in a random sequence. An automated source of random numbers is capable of generating random numbers at a specific rate or over a defined interval.

    Random number generators can either be hardware-based or software programs.
    1. Hardware-based random number generators: These are termed ‘true random number generators’ and are high in precision. Here, objects such as a coin or dice are used for the generation of random numbers. Additionally, there are true random number generators that are based on physical phenomena such as electromagnetic noise, atmospheric noise, thermal noise, etc.
    2. Software-based random number generators: Also known as ‘pseudo-random number generators’, they use computer algorithms for generating random numbers. They have a limited scope when it comes to the degree of randomness of the numbers generated. While they are suitable to be used for a myriad of applications, these generators are not meant to be used for applications requiring high precision such as cryptography.

    How do these Random Number Generators work?
    These are software-based random number generators that have various applications including computer simulations, sequencing and modelling applications, gambling-based products, etc. Being online tools, these generators can be accessed from a mobile phone or a computer with an internet connection.

    Here’s a brief explanation of how the random number generators given above work:

    Random Number Generator
    This number generator can generate a random number within a specified range. The generator has two fields where the ‘lower limit’ and the ‘upper limit’ can be specified. The tool only accepts integers which can either be positive or negative. Here, the lower limit should not exceed the value of the upper limit. Enter the required values and click on the ‘Generate’ button to view the result.

    Output Shown: The result displayed is a random number generated by the system.

    Comprehensive Random Number Generator
    This tool allows users to generate a single or multiple random numbers that can either be integers or decimal numbers. Apart from fields to set the ‘lower limit’ and the ‘upper limit’ of the random number(s) generated, this generator also has several other features that allow users to further customize the number generated. These additional features have been discussed below:
    Users can specify the quantity of random number(s) to be generated
    Users can choose whether duplication should be allowed in the results generated or not
    The results can be sorted in an ascending, descending or no particular order
    Users can choose whether the result(s) shown should be an integer(s) or decimal number(s)
    Users can also set the precision of the numbers generated up to 999 digits/decimal places
    Enter the required details and click on the ‘Generate’ button to view the result.

    Output Shown: The result displayed is a random number or various random numbers generated by the system.
