block device
A block device is a type of data storage that manages information in fixed-size chunks called blocks. Each block can be read or written independently, allowing for efficient handling of data. Common examples of block devices include hard drives, solid-state drives (SSDs), and USB drives. They are used by computers to store files and run programs because they provide quick access and reliability. Unlike other devices that might handle data in a continuous stream, block devices enable random access to any part of the data, making them versatile and essential for modern computing.

A block device is a type of hardware that stores data in fixed-size blocks or chunks. This allows the operating system to read from or write to these blocks individually, making it efficient for managing large amounts of data. Examples include hard drives, solid-state drives, and USB flash drives. Block devices are crucial for tasks like saving files, running applications, and managing system data because they can quickly access different parts of the storage without reading the entire drive, much like picking out specific chapters from a book rather than reading it from start to finish.
