Understanding How Servers Work
A server is a broad term for both general and specific computer applications. In computing, it may refer to a computer program serving the needs of another program, or a computer running exclusively to serve the needs of one or more computers in the same network. It is a physical or virtual device that enables multiple end-users to access and share data across a network. Generally, a server may provide services to multiple private users within a private organization or to public users through the Internet. Nearly all companies today use servers to store, process, and share information to provide services specifically customized to their business needs. This type of server only provides services to users in a single facility. On the other hand, there are servers used to provide services to distant users via the Internet. Public servers are normally larger than private servers since they serve a larger group of users. The public servicing process involves three major elements—the user who demands for a specific service, the Internet that conveys the demand towards the server that contains the service, and the server that in turn provides the service via the Internet. In contrast, private servicing through a server may or may not use the Internet as a medium of information sharing. Traditionally, servers come in huge hardware that needs tedious and careful upkeep. Because of these, only those companies that can afford can benefit from this expensive technology, limiting the chance of smaller companies to extend services to a larger populace through the Internet. Some resort to purchasing the best used servers that can only provide restricted services. Thanks to cloud computing, businesses proving services through the Internet no longer need physical servers to serve the needs of their clients. They can now limit the task of their best used servers to private operations. Cloud computing is the storage, processing, and delivery of services through the Internet. In cloud computing, large websites, referred to as server clouds, act as online servers. Instead of individuals or organizations keeping information and performing specific commands for the benefit of their online clients through physical servers, these virtual clouds provide an even faster set of services specific to their business needs. However, they can still buy refurbished server hardware for internal operations.
