Memory Allocation Visualizer

A beautiful web-based application that simulates OS memory management using First Fit and Best Fit algorithms.

Features

• 🎨 Modern, responsive UI
• 📊 Visual representation of memory allocation
• 💾 First Fit and Best Fit algorithms
• 📈 Internal fragmentation calculation
• 📱 Mobile-friendly design

Installation

1. Install dependencies:

pip install -r requirements.txt

Running the Application

1. Start the Flask server:

python app.py

2. Open your browser and navigate to:

http://localhost:5000

Usage

1. Select an algorithm (First Fit or Best Fit)
2. Enter memory partition sizes (space-separated integers in KB)
   • Example: 900 910 300 250
3. Enter process sizes (space-separated integers in KB)
   • Example: 275 690 155 750
4. Click "Run Allocation" to see the results

Algorithms

First Fit

Allocates each process to the first available partition that is large enough.

Best Fit

Allocates each process to the smallest available partition that can accommodate it, minimizing wasted space.

Output

The results page displays:

• Job overview with sizes
• Memory block allocation details
• Status (Allocated/Not Allocated)
• Internal fragmentation for each block
• Total statistics (memory used, available, internal fragmentation)
