The term "append" refers to the action of adding something to the end of an existing item or list. In computer programming, for example, it often involves adding new data to an array or a file. This operation is commonly used in various programming languages, such as Python and Java, to manage collections of data efficiently. In everyday contexts, "append" can also describe adding information to a document or a report. For instance, when writing a paper, you might append additional notes or references at the end to provide more context or support for your arguments. This ensures that all relevant information is included in one place.
