A Random Access File is a type of data storage that allows information to be read or written in any order, rather than sequentially. This means that you can quickly access specific pieces of data without having to go through the entire file. This is particularly useful for large files where speed and efficiency are important. In programming, random access files are often used in languages like C or Java to manage data efficiently. They enable developers to manipulate data records directly, making it easier to update, delete, or retrieve information as needed, which enhances overall performance in applications.
