Usability Trade-offs: Mac OS made usability its main priority and therefore sometimes sacrificed power user capabilities. Windows 95 had more functionality but with more complexity that could confuse the novice user.
β‘ Multitasking Capabilities
Cooperative Multitasking: Mac OS
How it worked - Applications agreed voluntarily to give up some processor time to other programs.
Characteristics:
- Application Responsibility: Programs controlled the CPU usage
- Smooth Performance Well-behaved apps offered fluid experience
- System Vulnerability: An app that is frozen could be the reason for entire system to hang up
- Predictable Behavior: Applications ran with predictably the same behavior
- Reduced Overhead: Limited system intervention in the task switching
Real-world Impact: Creative applications such as Photoshop and QuarkXPress could potentially hog system resources as needed and thus be able to provide optimal performance for intensive operations.
πͺ Windows 95: Preemptive Multitasking.
How it worked: Operating system had control over allocation of the CPU and could switch between applications forcibly.
Characteristics:
- OS Control: System controlled all task switching
- Better Stability: Frozen apps which are less likely to crash system
- Fair Resource Sharing: CPU time was gotten by all applications
- 32-bit Applications - Full support for preemptive multitasking of modern applications
- 16-bit Compatibility: DOS/Windows old apps have been cooperative model

| Performance Overhead | Minimal - applications self manage | Moderate - OS manages task switching |
| Responsiveness | Depends on application co-operation | Consistent across all applications |
| Resource Allocation | Applications can have monopolistic resources | Fair sharing enforced by OS |
| Background Processing | Limited due to cooperative nature | True background processing available |
Evolution Impact: The multi-tasking approaches of these systems had an influence over the modern OS design. Mac OS X switched to preemptive multitasking where as Windows continued to develop and fine tune its preemptive model in future versions.
π File System Architecture
ποΈ HFS: Hierarchy File System
Mac OS choosen the Hierarchical File System (HFS), made for simplicity and media optimisation:
Key Features:
- Case-Sensitive: Called into effect from differentiating between "File.txt" and "file.txt"
- Resource Forks: Files could have data & resource components
- Type/Creator Codes Four-character codes identified file types and applications
- Alias System: Smart short-cut which tracked moved files
- Desktop Database: Information for file types and icons that would be centralized
File Structure ExampleHere is an example of its file structure: MyDocument.doc--->Data Fork (the document content)--->Resource Fork (formatting, icons) Type Code: 'WDBN' (Word document) Creator Code: 'MSWD' (Microsoft Word)
πΎ FAT32: File Allocation Table
Windows 95 added FAT32 to the possibilities of the original FAT file system:
Key Features:
- Case-Insensitive "File.txt" and "file.txt" were the same
- Long Filenames: I can have more than 255 characters (more than 8.3 DOS limit)
- Large Volume Support: Support for partitions upto 2TB
- Improved Efficiency: Could make better use of every single space (as compared to FAT16)
- DOS Compatibility: Backward compatible
Filename Evolution Demonstrated DOS (8.3): MYDOCU~1.DOC Windows 95: My Important Document.doc (with 8.3 alias for compatibility)
File System Comparison
| Feature | HFS (Mac OS) | FAT32 (Windows 95) |
|---|---|---|
| Maximum Filename Length | 31 characters | 255 characters |
| Case Sensitivity | Case sensitive | Case-insensitive (preserving) |
| File Identification | Type/Creator codes | File extensions |
| Maximum File Size | 2GB | 4GB |
| Metadata Storage | Resource forks, desktop database | File attributes, registry |
| Fragmentation Handling | Automatic defragmentation | Manual defragmentation tools |
HFS Innovation: Resource forksrowth to Mac files allowed self-contained with embedded icons, version information and application data creating a more integrated user experience.
FAT32 Practicality Long filename support and large volume capacity combined to make Windows 95 more practical for business and power users that had to manage large collections of files.
File Management Philosophy
The differences on the file system represented larger conceptions philosophically:
- Mac OS Approach Files as intelligent objects that incorporate metadata and behaviour
- Windows 95 Approach Files as data containers + external associations and attributes
Cross-Platform Challenges: These different file system approaches introduced substantial compatibility issues in using files across platforms of Mac and PC systems which required special softwares to translate or in case of files metadata has to be taken care of.
