Features:

• Remote Access using the RFB algorithm (captures only screen changes).
• Data Compression for efficient communication.
• File Sharing capabilities.
• Chat feature for communication.
• Form Inheritance to access multiple machines simultaneously in separate windows.

⚙️ How It Works

1. The Client connects to the Server.

   • The first socket initializes and connects others (for image transfer, file operations, or remote keyboard input).
   • It transfers messages, mouse position, and clicks.

2. The Server requests an initial screen capture.

   • The Client captures the screen as an 8-bit Bitmap to reduce size.
   • The image is compressed with zLib and sent to the Server.
   • The image is saved in memory.

3. Subsequent requests:

   • The Client compares the new capture with the previous one.
   • Only differences are sent, compressed to minimize data size.
