What defines a 'file' in computing?

In computing, a 'file' is defined as a sequence of bytes representing data. This is foundational to understanding how data is stored, organized, and retrieved on storage devices. A file can contain a variety of information, including text, images, audio, or executable instructions, all represented as a series of bytes. These bytes together give structure to the data, allowing it to be identified, read, and manipulated by software applications.

The representation of data as bytes is crucial because it determines how the operating system and programs interact with the file. The byte sequence helps the system understand the content type and its intended use, facilitating actions such as reading from, writing to, or executing the file.

Understanding this concept is essential for anyone involved in computing, as it provides the groundwork for more complex topics, including file systems, data management, and programming.
