Separators are tools or devices used to divide or distinguish different elements within a system. They can be physical objects, like walls or fences, or conceptual tools, such as categories in data organization. In various fields, separators help maintain order and clarity by preventing confusion between distinct items or groups. In the context of programming, separators often refer to characters or symbols that delineate data, such as commas in a CSV file. They play a crucial role in data parsing, ensuring that information is correctly interpreted and processed by software applications.
