What does the term 'data blocks' refer to in storage?

The term 'data blocks' refers to units of data that contribute to a larger file. In the context of storage, a file stored on a disk is divided into smaller, manageable pieces known as blocks. Each block is a fixed-size container in which data is stored, and files may be composed of multiple blocks. This organization facilitates efficient data retrieval, management, and storage optimization.

For example, when a computer reads or writes a file, it does so in terms of these blocks. Even if a file occupies a large amount of space, it is handled modularly as several blocks, allowing for faster processing and easier management of disk operations. This concept is essential for understanding how storage systems, including hard drives and SSDs, function on a fundamental level.
