Description: A logical block is a unit of data storage defined in logical terms, often used in various storage technologies, including file systems, databases, and cloud storage. Unlike physical blocks, which refer to the storage structure in hardware, logical blocks are an abstraction that allows operating systems to manage memory more efficiently. These blocks are fundamental for organizing and accessing data, as they enable operating systems and applications to interact with storage without needing to know the underlying physical details. Their size can vary, but is commonly set in multiples of 512 bytes, facilitating the reading and writing of data in larger units. This abstraction not only improves data access efficiency but also allows for the implementation of features such as compression and deduplication, further optimizing storage space usage.
