    Study Notes

    File Management Overview

    • Key components of file management include file abstraction, directory abstraction, file systems, and caching.
    • The chapter does not cover hardware management of storage devices; that will be addressed in the subsequent chapter on I/O and devices.

    Volatile vs. Non-Volatile Memory

    • Volatile Memory

      • Requires power to retain stored information.
      • Data loss occurs when power is lost.
      • Common examples: RAM and CPU caches.

    • Non-Volatile Memory

      • Retains stored information without requiring power.
      • Examples include hard disk drives (HDD) and solid-state drives (SSD).

    • General Characteristics

      • Volatile memory is typically faster than non-volatile memory.
      • Faster memory usually has a higher cost per byte.
      • CPU register access time is approximately 1 nanosecond (ns).

    File Management Overview

    • Key components of file management include file abstraction, directory abstraction, file systems, and caching.
