In a client-server application on the web using sockets, the server must come up first.How client-server architecture worksA client-server application is a type of distributed application that processes the workload between the server and clients. This application is built on the client-server architecture. It is important to note that the architecture consists of two types of machines: the client and the server. Each machine performs specific functions in the application.In this architecture, the server provides services and resources to the client. When a client requests a service or resource from the server, it sends a request to the server. The server processes the request and responds with the required service or resource to the client.In a client-server application on the web using sockets, the server must come up first. This is because the server provides services and resources to the client. The client can only request the service or resource from the server after the server is up and running. Therefore, if the server is not up and running, the client will not be able to access the services or resources it needs.
