🧠 Memory Management Simulator — Best Fit Allocation

A modern, interactive Web-based Memory Management Simulator that demonstrates how processes are allocated in memory using the Best Fit algorithm under:

Fixed Partitioning

Variable Partitioning

This project is designed to help students understand core Operating System concepts through real-time visualization.

🚀 Features

🎯 Best Fit Memory Allocation

🧩 Supports:

Fixed Partitioning

Variable Partitioning

📊 Real-time Memory Visualization

📋 Process Table Tracking

📐 Fragmentation Analysis:

Internal Fragmentation

External Fragmentation

🔄 Reset & Next Process Simulation

🎨 Modern UI with animations and particle background

⚙️ How It Works

Enter:

Process ID

Process Size

Memory Block Sizes (minimum 4 blocks)

Select Partition Type:

Fixed

Variable

Click Allocate Memory

The simulator:

Finds the best-fit block

Allocates memory

Updates visualization

Shows fragmentation

🧮 Best Fit Algorithm

The Best Fit strategy selects the smallest available memory block that can accommodate the process.

Logic:

Traverse all free blocks

Choose block with minimum leftover space

Allocate process to that block

📊 Fragmentation Handling
🔹 Fixed Partitioning

Shows Internal Fragmentation

Unused memory inside allocated block is tracked

🔹 Variable Partitioning

Shows External Fragmentation

Free blocks may exist but not usable due to size mismatch

🛠️ Technologies Used

HTML5

CSS3 (Modern UI + Animations)

Vanilla JavaScript (ES6)

▶️ How to Run

Download or clone the repository:
