B. regular
C. directories
D. named pipes
Answer: B

A. logical file system
B. physical file system
C. special file type system
D. regular file type system
Answer: A
The physical file system is allocated to the parts of the logical file system. The logical file system can be implemented on a system with two hard disks by the allocation of the bin directory under the hard disk 1 and the file subsystem under the hard disk 2.
126. Which directory is allocated on the hard disk 1 of the physical storage in a Linux operating system?
A. term
B. dev
C. etc
D. bin
Answer: D

127. Which process defines the allocation of the mass storage to the logical file system?
A. mounting
B. de-allocation
C. demounting
D. unmounting
Answer: A
