Whereas the words server and client may refer either to a computer or to a computer program, server-host and client-host always refer to computers. The host is a versatile, multifunction computer; clients and servers are just programs that run on a host. In the client–server model, a server is more likely to be devoted to the task of serving.
Historically, a network operating system was an operating system for a computer which implemented network capabilities. Operating systems with a network stack allowed personal computers to participate in a client-server architecture in which a server enables multiple clients to share resources, such as printers.

The communication protocol between server and client runs network-transparently: the client and server may run on the same machine or on different ones, possibly with different architectures and operating systems. A client and server can communicate securely over the Internet by tunneling the connection over an encrypted connection. [2]
In computer science, interprocess communication (IPC) is the sharing of data between running processes in a computer system. Mechanisms for IPC may be provided by an operating system. Applications which use IPC are often categorized as clients and servers, where the client requests data and the server responds to client requests. [1]
Sometimes the more general term server or server process is used, particularly for daemons that operate as part of client-server systems. [5] After the term was adopted for computer use, it was rationalized as a backronym for Disk And Execution MONitor. [6] [1] Daemons that connect to a computer network are examples of network services.
The client stub packs the parameters into a message and makes a system call to send the message. Packing the parameters is called marshalling. The client's local operating system sends the message from the client machine to the server machine. The local operating system on the server machine passes the incoming packets to the server stub.
Upon accepting a client connection, the server then executes a read system call that will block wait. The client connects to the server's socket via the server's address. The client process then writes a message for the server process to read. The application's algorithm may entail multiple read/write interactions. Upon completion of the ...
Server and client An open connection, data received can be delivered to the user. The normal state for the data transfer phase of the connection. FIN-WAIT-1 Server and client Waiting for a connection termination request from the remote TCP, or an acknowledgment of the connection termination request previously sent. FIN-WAIT-2 Server and client
