Attributes associated with a file can be maintained in several places as discussed inthe course content:a. Within the set of open file descriptorsb. Within the system-wide file table entry for the filec. Within the ‘i-node’ (or ‘v-node’)These attributes can be associated with the actual file (e.g. the file size), or can be associatedwith an open instance of the file (e.g. whether the file is opened for reading or writing, whether thefile is opened for non-blocking I/O, etc.).What would be preferred location of the following attributes of a file and why? Discuss anytradeoffs if that attribute could be in more than one of the above.a. The owner of the file.b. The “read/write” pointer of the open file.c. Whether the file is opened for reading, writing, or both.

How do you complie the file with gcc if there are still errors in the code? When I tried to complie the code with gcc I received multiple syntax errors.

When it comes to copywriting, what is the difference between a shallow and deep copy?

What distinguishes the two file access techniques? What sets these two apart from one another?
