Provide examples of applications that typically access
files according to the following methods. Some systems
automatically open a file when it is referenced for the first
time and close the file when the job terminates. Discuss
the advantage, and disadvantages of this scheme
compared with the more traditional one, where the user
has to open and close the file explicitly. If the operating
system knew that a certain application was going to access
file data in a sequential manner, how could it exploit this
information to improve performance? Give an example of
an application that could benefit from operating-system
support for random access to indexed files.
