A class of small specialist servers called network appliances are generally at the low end of the scale, often being smaller than common desktop computers. Proprietary operating systems such as z/OS and macOS Server are also deployed, but in much smaller numbers. This architecture is called the client–server model. Web service. An MIT graduate who brings years of technical experience to articles on SEO, computers, and wireless networking. A network server is a computer system, which is used as the central repository of data and various programs that are shared by users in a network. Most home operating systems are also void of server-related features. A single server can serve multiple clients, and a single client can use multiple servers. Thus any general-purpose computer connected to a network can host servers. That machine might be a dedicated server or it might be used for other purposes. [a] The word service (noun) may refer to either the abstract form of functionality, e.g. The longer text box is the server name and the text box towards the right is the port. to understand the difference. As a rule, the larger the network in terms of clients that connect to it or the amount of data that it moves, the more likely it is that several servers play a role, each dedicated to a specific purpose. Since uptime is critically important for most servers, servers aren't designed to shut down but instead run 24/7. Wayback Machine is one example of a web archiver that stores snapshots of web pages and files stored on web servers. Read When to use a proxy and when to use a VPN?
