+# Reliable Transmission  
+
+**Reliable transmission** ensures that data sent over a network reaches its destination 
+accurately and in the correct order, a critical requirement for server-side game development. 
+`TCP` achieves this through mechanisms like acknowledgments (ACKs), sequence numbers, and 
+retransmission strategies. When a packet is lost or corrupted, `TCP` retransmits it using 
+algorithms such as automatic repeat request (ARQ) and fast retransmit. Additionally, flow 
+control and congestion control work together to prevent data loss due to network congestion. 
+Reliable transmission is essential for maintaining synchronization in multiplayer games, 
+preventing desynchronization issues, and ensuring a smooth gaming experience.
