A well-known type of server is a web server where web pages can be accessed over the internet through a client like a web browser. The Proxy server is responsible for a connection between a client(web browser or an app) with and an external server to entertain the request for connection, performance enhancement, and accessibility Most home operating systems are also void of server-related features. Large businesses that have multiple servers don't typically access these servers locally, like with a keyboard and mouse, but instead by remote access. The word cluster is used broadly in computer networking to refer to an implementation of shared computing resources. In fact, web hosting is simply a service in which you remotely lease web servers for your web site’s use. For example, some network-aware hard drives use the Network Attached Storage server protocol to allow different PCs on a home network to access a shared set of files. Critical components might be hot swappable, allowing technicians to replace them on the running server without shutting it down, and to guard against overheating, servers might have more powerful fans or use water cooling.
