TCP Networking
TCP (Transmission Control Protocol) Networking is a fundamental networking concept that involves the reliable, ordered, and error-checked delivery of data between applications over an IP network. It operates at the transport layer of the TCP/IP model, establishing connections through a three-way handshake and ensuring data integrity with flow control, congestion control, and retransmission mechanisms. This protocol is essential for applications requiring guaranteed data delivery, such as web browsing, email, and file transfers.
Developers should learn TCP Networking when building applications that require reliable data transmission, such as client-server systems, real-time communication tools, or any networked software where data loss is unacceptable. It is crucial for understanding network programming, debugging connectivity issues, and optimizing performance in distributed systems, making it a core skill for backend, full-stack, and network engineers.
