Detailed explanation-1: -The client makes a request for a service, and a server performs that service. Server functions often require some resource management, in which a server synchronizes and manages access to the resource, and responds to client requests with either data or status information.
Detailed explanation-2: -Client/server services are built as a layer on XCF signaling services and provide a simple implementation model that makes use of XCF and sysplex programming best practices. Note that the processing might not be suitable for some performance-sensitive applications.
Detailed explanation-3: -A server stores, sends, and receives data. In essence, it “serves” something else and exists to provide services. A computer, software program, or even a storage device may act as a server, and it may provide one service or several.
Detailed explanation-4: -A client initiates the communication by connecting to a server. The client sends requests to the server, and the server sends replies back. Finally, the client disconnects. A server might handle connections from many clients concurrently, and clients might also connect to multiple servers.
