Final answer:
The 'TCP Concurrent server, one thread per client' model is a network server design where each client connection is handled by a separate thread, facilitating multiple simultaneous connections through the use of the reliable Transmission Control Protocol.
Step-by-step explanation:
The model "TCP Concurrent server, one thread per client" refers to a server architecture used in network programming. In this model, the server is capable of handling multiple client connections at the same time by creating a new thread for each incoming client connection. Here, the Transmission Control Protocol (TCP) is used for reliable communication between the server and the client.
When a client initiates a connection to the server, the server spawns a new thread dedicated solely to that client. This thread handles all the communication with that client, receiving requests, and sending responses. The main advantage of this model is its straightforward implementation and the ability to serve multiple clients simultaneously with isolated processing for each. However, it can be resource-intensive because each connection requires a separate thread, which consumes system resources such as memory and processing power. When too many threads are created, it could lead to performance bottlenecks and scalability issues.
Typically, this model is utilized in scenarios where the number of clients is moderate, and the interaction with each client is complex or long-lived. Examples include chat servers or interactive gaming servers, where each client maintains a persistent connection and has a high level of interaction with the server.
