Client–server model is a distributed application structure that partitions tasks or workloads between the providers of a resource or service, called servers, and service requesters, called clients. Often clients and servers communicate over a computer network on separate hardware, but both client and server may reside in the same system. A server host runs one or more server programs which share their resources with clients. A client does not share any of its resources, but requests a server's content or service function. Clients therefore initiate communication sessions with servers which await incoming requests. Examples of computer applications that use the client–server model are Email, network printing, and the World Wide Web.
An operating system (OS) is system software that manages computer hardware and software resources and provides common services for computer programs.
A thin client is a lightweight computer that has been optimized for establishing a remote connection with a server-based computing environment. The server does most of the work, which can include launching software programs, crunching numbers, and storing data. This contrasts with a fat client or a conventional personal computer; the former is also intended for working in a client–server model but has significant local processing power, while the latter aims to perform its function mostly locally.
A management information system (MIS) is an information system used for decision-making, and for the coordination, control, analysis, and visualization of information in an organization; especially in a company.
A client is a piece of computer hardware or software that accesses a service made available by a server. The server is often on another computer system, in which case the client accesses the service by way of a network. The term applies to the role that programs or devices play in the client–server model.
Cincom Systems, Inc., is a privately held, multinational, computer technology corporation founded in 1968 by Tom Nies, Tom Richley, and Claude Bogardus.
Phoning Home, in computing, refers to an act of client to server communication which may be undesirable to the user and/or proprietor of the device or software. It is often used to refer to the behavior of security systems which report network location, username, or other such data to another computer.
A 3270 Emulator is a terminal emulator that duplicates the functions of an IBM 3270 mainframe computer terminal on a PC or similar microcomputer.
LINC is a fourth-generation programming language, used mostly on Unisys computer systems.
A network host is a computer or other device connected to a computer network. A network host may offer information resources, services, and applications to users or other nodes on the network. A network host is a network node that is assigned a network address.
Desktop virtualization is software technology that separates the desktop environment and associated application software from the physical client device that is used to access it.
SME Server is a Linux distribution based on CentOS offering an operating system for computers used as web, file, email and database servers. It employs a comprehensive UI for all management-related tasks and is extensible through templates.
A clustered file system is a file system which is shared by being simultaneously mounted on multiple servers. There are several approaches to clustering, most of which do not employ a clustered file system. Clustered file systems can provide features like location-independent addressing and redundancy which improve reliability or reduce the complexity of the other parts of the cluster. Parallel file systems are a type of clustered file system that spread data across multiple storage nodes, usually for redundancy or performance.
EntireX DCOM is a commercial implementation of Microsoft's Distributed Component Object Model (DCOM) technology by Software AG for the Windows, AIX, HP/UX, Solaris, Linux, AS/400, z/OS, z/VM, and BS2000/OSD platforms.
In computing, virtualization refers to the act of creating a virtual version of something, including virtual computer hardware platforms, storage devices, and computer network resources.
Information technology infrastructure is defined broadly as a set of information technology (IT) components that are the foundation of an IT service; typically physical components, but also various software and network components.
An Information Technology Assistant is a person who works as an assistant in the IT business.
Linux on IBM Z is the collective term for the Linux operating system compiled to run on IBM mainframes, especially IBM Z and IBM LinuxONE servers. Similar terms which imply the same meaning are Linux on zEnterprise, Linux on zSeries, Linux/390, Linux/390x, etc. The terms zLinux or z/Linux are also sometimes used, but these terms are discouraged by IBM as they create the implication of an IBM-offered or IBM-distributed version of Linux, which is incorrect.
Computers can be classified, or typed, in many ways. Some common classifications of digital computers are summarized below. For others see Category:Classes of computers.
