    2. How can these problems be avoided?
  2. The open-file table is used to maintain information about files that are currently open. Do operating systems typically maintain a separate table for each process or just maintain one table that contains references to files that are being accessed by all processes and why?
  3. Operating systems can have a different set of failure semantics for remote file systems than for local file systems. What are the advantages and disadvantages of having a different set and why?
