File I/O (Input/Output) is a fundamental concept in programming that involves reading from and writing to files, allowing programs to persist data beyond runtime. Efficient handling of file I/O is crucial for performance and data integrity, especially in applications dealing with large volumes of data or requiring frequent read/write operations.

File I/O (Input/Output)

File I/O (Input/Output) is a fundamental operation in programming that allows for reading from and writing to files, enabling data persistence and interaction with the file system. Mastery of File I/O is essential for handling data storage, configuration files, logging, and more, across various programming languages and environments.

File I/O

Input/Output (I/O) refers to the communication between an information processing system, such as a computer, and the external world, which could be a human or another information processing system. It encompasses all the methods and devices used to transfer data to and from a computer, playing a crucial role in the functionality and usability of computing systems.
