A server acts as the central point for all programs and data over a network.
in this case , the another computer take the role of server
I think you are referring to Server. A Server is an elevated computer that is on a defined network that has a specific range of tasks, such as providing resources, services and security. A server plays an important role in building Domains in computer networking environments.
Simple: in order to have a client-server architecture you need a network. The role of the network is to move data packets between the client and the server. In a client-server architecture the server usually has to manage the network (for example, a domain controller in a Windows environment).
From a network topology perspective, a personal computer that is connected to the network is a node. From a software/OS perspective, this would be a network client, but personal computers can act as, or serve the role of, a server, but I think that is out of scope of the question.
In a small network, a network computer is the most likely candidate to act as a network server. Network computers are specifically designed to manage and facilitate communication and resource sharing among connected devices. While minicomputers can also serve as servers, they are typically larger and more powerful than what's needed for small networks. Supercomputers and laptops are generally not suited for this role due to their specific use cases and limitations.
A server role is a set of software programs that, when they are installed and properly configured, lets a computer perform a specific function for multiple users or other computers within a network. Generally, roles share the following characteristics.

A server is as the name suggests: it provides a serviceto a network of clients. In the world of the Internet today, this can range from Web servers (they run websites, including this site you're using now), game servers (these run online games where people can play with each other online), and much more.
A computer or program that is structured to accept requests from diverse network sources is typically termed a server. Servers hold the function of responding to numerous requests across a network and are pivotal in network management, aiding in the facilitation of information flow and resource allocation between computers. They perform a critical role in ensuring seamless network interactions, catering to a multitude of requests, and delivering the requisite responses or data back to the requesting entities. Balancing load, managing resources, and securing data are also integral parts of a server’s duties, making them indispensable in maintaining the efficacy and security of network communications.
The main function of NOS is to provide server type of role to enhance support or make a working network.
