![]() Such servers are often referred to as virtual servers. These days, a server may be nothing more than software running on one or more physical computing devices. In previous computing models, such as the mainframe-terminal model, the mainframe did act as a server even though it wasn’t referred to by that name.Īs technology has evolved, the definition of a server has evolved with it. ![]() This network architecture is often referred to as the client-server model, in which both the client computer and the server possess computing power, but certain tasks are delegated to servers. Later, servers were often single, powerful computers connected over a network to a set of less-powerful client computers. The actual computing was done on the server. These terminals, referred to as dumb terminals, existed simply to accept input via a keyboard or card reader and to return the results of any computations to a display screen or printer. Initially, such servers were connected to clients known as terminals that did not do any actual computing. However, as technology progressed, they ended up becoming much larger than desktop computers, which made the term microcomputer somewhat farcical. Minicomputers were much smaller than mainframe computers, hence the name. Some of the first servers were mainframe computers or minicomputers. This means that a device could be both a server and a client at the same time. An individual system can provide resources and use them from another system at the same time.
