Which of the following file systems was the first to be designed specifically for Linux?

  1. FAT

  2. NTFS

  3. UFS

  4. EXT

The correct answer is: EXT

The EXT file system, specifically the EXT2 variant, was indeed the first file system designed specifically for the Linux operating system. Its development began in the early 1990s as a way to provide an efficient and high-performance file system that would meet the needs of UNIX-like operating systems, including Linux. EXT brought several advantages over existing file systems, such as better support for larger file sizes and improved performance with file system operations. It introduced features like extents for efficient disk usage, journaled logging in later versions, and a more flexible architecture which allowed for greater compatibility with a variety of storage media. In contrast, other file systems mentioned in the question, like FAT and NTFS, were developed by Microsoft and are primarily associated with Windows operating systems. UFS, while used in some UNIX systems, was not specifically designed for Linux, and its primary implementations are found in BSD variants. Therefore, EXT rightfully holds its place as the pioneering file system tailored for Linux, laying the foundation for later versions like EXT3 and EXT4, which introduced journaling capabilities and further enhancements.
