CompTIA A+ Core 2 (220-1202)Operating SystemsMedium
A technician is preparing to install Linux on an older computer with limited storage capacity. The computer will primarily be used for basic web browsing and document editing. Which of the following file systems would be the MOST efficient choice for this scenario, considering both performance and storage overhead?
- ANTFS
- Bext4
- CFAT32
- DAPFS
Show answer & explanationAnswer & explanation
Correct answer: B. ext4
ext4 (Extended File System 4) is the default and most widely used file system for Linux distributions. It offers good performance, journaling for data integrity, and is optimized for Linux, making it the most efficient choice for a Linux installation.
Why the other options are wrong
- A. NTFS is the primary file system for Windows and is not natively fully supported or optimized for Linux system installations.
- C. FAT32 is an older file system with limitations (e.g., 4GB file size limit, 32GB partition size limit) and lacks journaling, making it unsuitable for a modern Linux operating system installation.
- D. APFS (Apple File System) is designed for macOS and iOS devices and is not compatible with Linux.
ext4 (Extended File System 4)
The default and most commonly used journaling file system for Linux distributions, offering improved performance, reliability, and features over its predecessors (ext2, ext3).
- Supports large file sizes (up to 16TB) and volume sizes (up to 1EB).
- Includes journaling for faster recovery from crashes and data integrity.
- Optimized for modern solid-state drives (SSDs) and traditional hard drives.
Memory trick: Ext4 is the 'EXTended' choice for 'EXactly' what Linux needs!
