Meaning – A dotted decimal notation, is a type of representation of numerical data, that is different from the conventional methods of notation. This method of data representation is used to replace “octets” eight individual bits) in machine language. Dotted decimal notation effectively does this by putting numbers in different containers that are separated by dots or decimals.
When it comes to changing the set of bytes into a decimal dotted notation, the ones and zeroes that make up the various bytes of data, are replaced by decimal delineated numbers ranging from 0 to 255.
This dotted decimal notation system is used to represent IP addresses of websites, and in IP version 4 addresses, which are 32 bits long, this results in four numbers.
Example of usage – “When she was studying IP addresses, the first thing she studied was how to understand and perform dotted decimal notation.”
