C. CD data copy prepared in a Linux system

This question is the same as 87, and the answer on that one was C
C 2
Selected Answer: C CDFS = Linux

A CDFS (Compact Disc File System) is a file system specifically made for optical discs like CDs. It is commonly tied to Windows operating systems and may not be the default file system used in Linux. Linux systems often use the ISO 9660 file system for CD-ROMs and DVDs. ISO 9660 is a standard file system for optical disc media, and it is widely supported across different operating systems, including Linux. Therefore, if you encounter an ISO file that is saved in CDFS format, it's more likely to be associated with a Windows-based system. For Linux-based systems, ISO 9660 is a more common file system for optical discs.

Selected Answer: A A. CD data copy prepared in Windows Explanation: CDFS (Compact Disc File System) is widely used for managing CD-ROM data, and it is most commonly linked to Windows systems, where it is natively supported for reading ISO 9660 file systems. While Linux and macOS can also read and write CDFS/ISO 9660 file systems, the question points to the most common use case, which is in a Windows environment. Why the Other Options Are Incorrect: B. CD data copy prepared in Mac-based system Mac systems often use HFS+ or APFS for disk management and do not natively default to CDFS/ISO 9660 unless specifically formatted for compatibility. C. CD data copy prepared in Linux system (Most Voted) Linux systems can read and write ISO 9660, but CDFS is not specific to Linux and is less commonly prepared on Linux compared to Windows. D. CD data copy prepared in Android-based system Android systems are not typically used to prepare CD data. They lack direct support for handling CDFS/ISO 9660 files natively.

Selected Answer: A An ISO file that is saved in CDFS format is a CD data copy prepared in Windows. Here's why: CDFS (Compact Disc File System) is largely synonymous with ISO 9660, which is the international standard for organizing data on CD-ROMs. However, "CDFS" specifically often refers to the Microsoft implementation of ISO 9660, which includes extensions like Joliet (for longer filenames and a wider character set) that are commonly used when burning CDs in Windows. While other operating systems (Linux, macOS) can also read and create ISO 9660 images, the term "CDFS format" in this context often specifically points to the way Windows handles CD file systems. DVDs typically use UDF (Universal Disk Format), not CDFS.

Please ignore my last message, pls clarify answers for ques 113 and 175 , supposed not to be the same answer Linux?

CDFS is not tied to a single Operating System, it means that a disc burned on Macintosh using CDFS can be read on a Windows or Linux based computer. Any input??

please think carefully before you post and regret your statement.

Selected Answer: C CDFS - Compact Disc File System CDFS - It is a virtual file system for Unix-like operating systems; it gives access to data and audio tracks on Compact Discs. - When the CDFS driver mounts a Compact Disc, it shows each track as a file. - This matches the Unix convention "everything is a file".

CD data copy prepared in a Linux system An ISO file saved in CDFS format usually means it was created in a Linux-based system. CDFS stands for "Compact Disc File System," and Linux often uses this format for CD/DVD images. So, the evidence in this case is likely a CD data copy prepared in a Linux system.

This question is an - any selection will match - because the CDFS standard was developed independently of any OS.

Selected Answer: A CDFS (Compact Disc File System) is the standard file system Windows uses to read and show the contents of a CD-ROM.

Selected Answer: C Correct answer is C. While Windows can read these, CDFS (Compact Disc File System) is a file system driver for the Linux kernel that lets the operating system read and export tracks from audio CDs as files
