<h4 id="comparision">Comparison Between Multithreading and Multiprocessing</h4>
<table>
<tr>
<th>Aspect</th>
<th>Multithreading</th>
<th>Multiprocessing</th>
</tr>
<tr>
<td>Memory Usage</td>
<td>Less memory usage/Shared memory space</td>
<td>More memory usage/Separate memory space for each process</td>
</tr>
<tr>
<td>Concurrency Type</td>
<td>Concurrent threads within a single process</td>
<td>Parallel processes with separate memory spaces</td>
</tr>
<tr>
<td>GIL Impact</td>
<td>Affected by GIL (only one thread executes Python code at a time)</td>
<td>No GIL; multiple processes can run Python code simultaneously</td>
</tr>
<tr>
<td>Best For</td>
<td>I/O-bound tasks (e.g., web scraping, file I/O)</td>
<td>CPU-bound tasks (e.g., heavy computations)</td>
</tr>
<tr>
<td>Synchronization</td>
<td>More complex due to shared state</td>
<td>Less complex but requires IPC for communication</td>
</tr>
<tr>
<td>Overhead</td>
<td>Lower overhead, but limited by GIL</td>
<td>Higher overhead due to process creation and management, but no GIL limitation</td>
</tr>
<tr>
<td>Fault Isolation</td>
<td>A thread crash can affect the entire process</td>
<td>A process crash is isolated to that process</td>
</tr>
