## 🌟 Overview

The WIA-COMP-005 standard defines the framework for modern operating systems, including kernel architectures, process scheduling, memory management, file systems, and system security.

**弘익人間 (Benefit All Humanity)** - This standard promotes secure, efficient, and accessible operating systems that empower users worldwide and enable innovation at all levels of computing.

## 🎯 Key Features

- **Kernel Architectures**: Monolithic, microkernel, hybrid, unikernel
- **Process Scheduling**: CFS, O(1) scheduler, real-time scheduling
- **Memory Management**: Virtual memory, paging, TLB, NUMA
- **File Systems**: ext4, Btrfs, ZFS, F2FS
- **Security**: SELinux, AppArmor, capabilities, sandboxing
- **Containerization**: Namespaces, cgroups, Docker, Kubernetes
- **Device Drivers**: Plug-and-play, hotplug, driver frameworks
- **Inter-Process Communication**: Pipes, shared memory, signals
- **System Calls**: POSIX compliance, system call interface
- **Power Management**: ACPI, CPU governors, suspend/resume

## 📊 Core Concepts

### 1. Kernel Architectures

```
Architecture Types:
- Monolithic: Linux, Unix (all services in kernel space)
- Microkernel: Minix, L4 (minimal kernel, services in user space)
- Hybrid: Windows NT, macOS (combination approach)
- Unikernel: MirageOS, IncludeOS (library OS, single address space)
```

### 2. Process States

| State | Description | Transitions |
|-------|-------------|-------------|
| New | Process created | → Ready |
| Ready | Waiting for CPU | → Running |
| Running | Executing on CPU | → Ready, Blocked, Terminated |
| Blocked | Waiting for I/O | → Ready |
| Terminated | Execution complete | (final state) |

## 🔧 Components

### TypeScript SDK

```typescript
import {
  analyzeScheduler,
  optimizeMemory,
  benchmarkFileSystem,
  validateSecurity
} from '@wia/comp-005';

// Analyze scheduling policy
const scheduler = analyzeScheduler({
  policy: 'CFS',
  processes: 100,
  cpuCores: 16,
  realTimeRatio: 0.1
});

console.log(`Context Switches: ${scheduler.contextSwitches}/sec`);
console.log(`Average Latency: ${scheduler.avgLatency} ms`);
```

### CLI Tool

```bash
# Analyze kernel configuration
wia-comp-005 analyze-kernel --arch monolithic --version 6.5

# Benchmark file system
wia-comp-005 benchmark-fs --type ext4 --operations 10000

# Validate security policy
wia-comp-005 validate-security --policy selinux --level strict
```

## 🌐 WIA Integration

This standard integrates with:
- **WIA-INTENT**: Intent-based system configuration
- **WIA-BLOCKCHAIN**: Immutable audit logging
- **WIA-QUANTUM**: Quantum-resistant security

## 📖 Use Cases

1. **Server Infrastructure**: Linux, Windows Server
2. **Cloud Computing**: Container orchestration, virtualization
3. **Embedded Systems**: Real-time OS, IoT devices
4. **Mobile Devices**: Android, iOS
5. **Desktop Computing**: Windows, macOS, Linux distributions
6. **High-Performance Computing**: Lightweight kernels
7. **Safety-Critical Systems**: Aerospace, automotive OS
8. **Research & Education**: Teaching OS concepts
