A network computing environment is one in which an organization has linked together personal computers that have been connected into a network. There are a number of types of computer networks.
Local area network: A computer network located within a relatively limited area such as a building, agency or university campus. Also known as a LAN.
Wide area network (WAN): A computer network that covers a large geographical area.
The purpose of networking personal computers and even mainframes together is to permit employees in the organization to
• communicate with one another as well as others outside the organization, normally through the use of electronic messages
• access information and services supported on the World Wide Web
• share documents and data
• support various work processes in the organization based on the automation of specific tasks.
A computer that is not connected to a network is referred to as a stand-alone computer. When a computer is physically connected to a local area network, using a cable or other communications channel, the computer becomes a workstation on the network. Each device on the network including workstations, servers, and printers is referred to as a node.
A workstation normally has all of the usual resources found in the personal computing environment (hard drive, software, data and printer). However, users of workstations will also have access to network resources, which typically include application software, storage space for data files, and printers other than those on the local workstation. On a network, the network server typically provides the applications
software and storage space for data files.
An application server is a computer that runs applications software and runs the results of processing to workstations as requested. An application server makes it possible to use the processing power of both the server and the workstation. Use of an application server splits processing between the workstation client and the network server. The method is also referred to as client/server architecture.
The main advantage of a computer network is that all the users can share resources, rather than have users each maintain his or her own resources. It is not necessary to purchase multiple copies of software; instead a license can be purchased to use the software within the network which allows everyone to use the program at the same time.
An internal network that belongs to an organization and is accessible only by that organization members is often referred to as an Intranet. Intranet is an internal computer network that belongs to an organization and is accessible only by that organization's members.
