In the dynamic landscape of operating systems, Linux and Windows have long been the titans vying for dominance. Each operating system brings unique strengths, catering to diverse user needs and preferences.

Linux, born from the open-source ethos in the early 1990s, has grown into a versatile platform celebrated for its stability, security, and customisation. Conversely, Windows, a proprietary system with roots in the graphical user interface (GUI) revolution of the 1980s, has become synonymous with user-friendliness and widespread compatibility.

This article delves into a comprehensive comparison of Linux and Windows, exploring their core functionalities, including file systems, file structures, security measures, software compatibility, and cost implications. By understanding the nuances of each system, businesses and individuals can make informed decisions aligned with their specific goals and requirements.

Linux vs Windows: File System Comparison

A file system is the fundamental structure through which operating systems organise and manage data on storage devices. It dictates how files and directories are located, accessed, and stored. The choice of file system significantly impacts performance, reliability, and data integrity.

Windows File Systems

Historically, Windows relied on FAT (File Allocation Table) and its successor, FAT32 (File Allocation Table 32). While simple and compatible with older systems, these FAT file systems had limitations in terms of file size, partition size, and performance.

So, NTFS (New Technology File System) emerged as the standard for modern Windows systems, offering enhanced features like journaling, security, and support for large files and volumes. While NTFS remains the primary file system for Windows, Microsoft has continued to enhance it with features like deduplication, compression, and better performance optimisations.

Linux File Systems

Linux, in contrast, typically uses the ext (extended) file system family, with ext4 being the most common. The ext file system is known for its stability, performance, and ability to handle large files and partitions. It also provides journaling, which helps maintain data integrity in the event of a system crash or power failure.

Linux boasts a diverse range of file systems, each tailored for specific use cases. The most common include:

• ext2, ext3, ext4: The extended file system family is known for reliability and performance. Ext4 is the most widely used and offers features like journaling, metadata checksums, and efficient resource allocation. It continues to evolve with improvements in performance and reliability.
• XFS: It is optimised for high-performance and large file systems and is often used in server environments.
• Btrfs: This file system is relatively new and has advanced features like copy-on-write, snapshots, self-healing capabilities, and data integrity checks.

Key Differences

Feature	Windows (NTFS)	Linux (ext4, Btrfs)
Journaling	Yes	Yes (ext4), Yes (Btrfs)
File Size Limits	Large (up to 16 exabytes)	Large
Performance	Good, better then FAT	Excellent (ext4), Very good (Btrfs)
Features	• File permissions • Encryption • Compression • Quotas • Deduplication	• Open source and free to use • Extensive metadata • Online file system checks • Flexible permissions • Snapshots • Copy-on-write • Self-healing
