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).
