Applications, as most people learn, are computer programs that perform specific set of jobs. Examples include Microsoft word, a word-processing application, along with QuickBooks, an accounting plan. In past years, users would install these programs independent hard drives. In additional cases, businesses would deploy a multiuser version in the software on a incurable server that their employees would access by using a local network. Terminal servers saved companies the trouble and costs of physically calibrating, patching, and repairing each individual desktop PC and all its applications.
