1. What is a file system?
a) A hardware component responsible for storing data on disks
b) A software component responsible for managing and organizing data on storage devices
c) A network protocol used for transferring files between computers
d) A graphical user interface for accessing files and folders
Answer: b) A software component responsible for managing and organizing data on storage devices
Explanation: A file system is a method and data structure used by operating systems to manage and store files on storage devices such as hard drives or SSDs.
2. What does the term “geometry” refer to in computing?
a) The mathematical study of shapes and sizes
b) The arrangement of physical components within a computer
c) The logical structure of a disk’s data storage
d) The process of converting analog signals to digital signals
Answer: c) The logical structure of a disk’s data storage
Explanation: In computing, “geometry” typically refers to the logical layout or structure of data storage on a disk, including parameters such as cylinder, head, and sector.
3. What does a disk controller do?
a) Controls the speed of the computer’s processor
b) Manages the flow of data between the CPU and memory
c) Regulates the rotation speed of a disk drive’s platters
d) Oversees the reading and writing of data to and from a disk
Answer: d) Oversees the reading and writing of data to and from a disk
Explanation: A disk controller is a hardware component or integrated circuit that manages the flow of data between the computer’s CPU and memory and the disk drive, handling tasks such as reading and writing data.
4. Which file system is native to the Solaris operating system?
a) FAT32
b) NTFS
c) Solaris File System (SFS)
d) Ext4
Answer: c) Solaris File System (SFS)
Explanation: The Solaris File System (SFS) is a native file system used by the Solaris operating system for organizing and managing data on disks.
5. What are disk-based file systems?
a) File systems stored entirely on solid-state drives (SSDs)
b) File systems that utilize optical disks for data storage
c) File systems that manage data stored on magnetic disks
d) File systems accessed over a network connection
Answer: c) File systems that manage data stored on magnetic disks
Explanation: Disk-based file systems are those that manage data stored on magnetic disks, such as hard disk drives (HDDs).
6. Which type of file system operates over a network connection?
a) NTFS
b) Ext4
c) FAT32
d) Network-based file system
Answer: d) Network-based file system
Explanation: Network-based file systems allow remote access and sharing of files over a network, enabling users to access files stored on remote servers as if they were local.
7. What is a virtual file system?
a) A file system that exists only in virtual reality environments
b) A file system that manages virtual machines’ storage resources
c) An abstraction layer that provides a unified interface to different types of file systems
d) A file system that stores files in a virtualized environment
Answer: c) An abstraction layer that provides a unified interface to different types of file systems
Explanation: A virtual file system is an abstraction layer in an operating system that provides a consistent interface to various underlying file systems, allowing applications to access files regardless of the specific file system being used.
8. What does UFS stand for in the context of file systems?
a) Unified File System
b) Universal File System
c) Unix File System
d) Unique File System
Answer: c) Unix File System
Explanation: UFS stands for Unix File System, which is a file system commonly used in Unix and Unix-like operating systems for organizing and managing data on disks.
9. Which component of a file system contains information about the file system itself, such as its type and size?
a) The boot block
b) The super block
c) The inode
d) The directory entry
Answer: b) The super block
Explanation: The super block is a critical data structure in a file system that contains metadata about the file system itself, including its type, size, and layout.
10. What is the process of adjusting the parameters of a file system to optimize its performance called?
a) File system repair
b) File system initialization
c) File system tuning
d) File system defragmentation
Answer: c) File system tuning
Explanation: File system tuning refers to the process of adjusting various parameters and settings of a file system to optimize its performance, including parameters related to caching, disk I/O, and file allocation.
