 1. If you were creating an operating system to handle files, what are the six basic file operations that you should implement? (8 marks)
+  These size basic operations comprise the minimal set of required file operations.
+
   1. Creating a file. Allocate space and add directory entry.
   1. Writing a file. Write data starting at seek position in to a file.
   1. Reading a file. Read data from the seek position into a specified buffer.
   1. Repositioning within a file. Change the seek position in a file to read/write to/from.
   1. Deleting a file. Remove the file entry from the directory and release file space.
   1. Truncating a file. Reset size of file to 0 and keep other attributes.
+
+  Other common operations include appending new information to the end of an
