A passive entity that "listens" on a specific port. It stays ready to process requests and provide resources (like a website or a database entry).

The bridge between these two is the . In programming, a socket is an endpoint for communication, defined by an IP address and a port number. A programmer writes code to "open" a socket, allowing the client to dial into the server much like a telephone call. The Significance of the "Three-Way Handshake" Internetworking with TCP IP.

Manages end-to-end communication. TCP (Transmission Control Protocol) provides a reliable, connection-oriented service by sequencing packets and retransmitting lost data. UDP (User Datagram Protocol) offers a faster, "best-effort" connection for real-time needs like streaming. A passive entity that "listens" on a specific port

Handles the physical transmission of data via cables, fiber optics, or wireless signals. In programming, a socket is an endpoint for

Internetworking is made possible by the four-layer TCP/IP model, which abstracts the complex process of moving data into manageable stages:

An active entity that initiates communication. It sends a request to the server’s IP address and waits for a response.

For client-server programming to be reliable over TCP, the two must agree to talk through a "Three-Way Handshake" (SYN, SYN-ACK, ACK). This ensures that both the client and server have the bandwidth and readiness to exchange data before the actual payload is sent. This synchronization is what makes the internet stable enough for banking, commerce, and secure communication. Conclusion
