A server is a specialized computer system or software application that is used to provide resources, data or services to other computers. These computers are also referred to as clients, which use and have access to this data.
Servers play an important role in computer networks because they are responsible for managing requests sent by clients. They receive these requests continuously and reliably, process them and return the requested information or services. Services include file sharing, email communication, database access, website access and more. Servers can be purchased in a variety of configurations, from powerful rack servers in data centers to small servers used by small businesses or individuals.
Choosing the right server depends on the specific requirements, such as: Performance, scalability, service or storage capacity. Servers therefore play an important role in IT infrastructures, as they efficiently provide services and enable the shared use of resources.
