TCP Client-Server Sockets
Implement reliable, connection-oriented communication by building basic TCP client and server applications in Python.
TCP Sockets: Connection First
Welcome to building network applications with Python! This lesson focuses on TCP (Transmission Control Protocol) sockets, which are the backbone of reliable internet communication.
Unlike UDP, TCP is a connection-oriented protocol. This means a direct, stable link is established between two applications before any data is sent.
Why TCP is Reliable
TCP ensures your data arrives correctly and in order. It handles:
- Guaranteed Delivery: Data segments are retransmitted if lost.
- Ordered Data: Data arrives in the order it was sent.
- Error Checking: Data integrity is verified.
- Flow Control: Prevents a fast sender from overwhelming a slow receiver.
This makes TCP ideal for web browsing, email, and file transfers.
