What is a path? - A path is a sequence of directories used to reference a file. They can be relative or absolute. Why do we need file systems? - 1. Locate free storage space 2. Store information in a persistent way (survives process termination) 3. Allow more than one process to access the information store concurrently 4. Find information by human-accessible identifiers 5. Protect data from unauthorized use 6. Identifying types of data stored and programs that can read the data ...
