Other uses of supercomputers scientific simulations, (animated) graphics, fluidĭynamic calculations, nuclear energy research, electronic design, and analysis of geological data (e. Require immense amounts of mathematical calculations (number crunching). Supercomputers are very expensive and are employed for specialized applications that Supercomputer is a broad term for one of the fastest computers with very powerful and very fast processorsĬurrently available.
Supercomputer: An extremely fast computer that can perform hundreds of millions of instructions per Mainframe: A powerful multi-user computer capable of supporting many hundreds or thousands of users Minicomputer: A multi-user computer capable of supporting up to hundreds of users simultaneously. More powerful microprocessor and, in general, a higher-quality monitor.
A workstation is like a personal computer, but it has a Workstation: A powerful, single-user computer. Personal computer: A small, single-user computer based on a microprocessor. For example, every computer requires a bus that transmits data from one part of the computer toĬomputers can be generally classified by size and power as follows, though there is considerable overlap: In addition to these components, many others make it possible for the basic components to work togetherĮfficiently. Output device: A display screen, printer, or other devices that let you see what the computer has Input device: Usually a keyboard and mouse, the input device is the conduit through which data and Common mass storage devices include disk drives and Large amounts of data and programs between jobs. Mass storage device (slower, cheaper, long-term memory): Allows a computer to permanently retain Memory (fast, expensive, short-term memory): Enables a computer to store, at least temporarily, data, Instructions organized in programs (& quot software& quot ) which tell the computer what to do. All general-purpose computers requireĬentral processing unit (CPU): The heart of the computer, this is the component that actually executes The actual machinery (wires, transistors, and circuits) isĬalled hardware the instructions and data are called software. Modern computers are electronic and digital. Therefore computers can perform complex and repetitive procedures quickly, precisely and reliably. It can quickly store and retrieve large amounts of data. It can execute a prerecorded list of instructions (a program). It responds to a specific set of instructions in a well-defined manner.
It defines an industry that uses computers, networking, software programming, and other equipmentĪnd processes to store, process, retrieve, transmit, and protect information.Ī computer is an electronic device that can be programmed to manipulate symbols. Technology is maintained, upgraded, and replaced. Installation of networks network administration and security the design of web pages theĭevelopment of multimedia resources the installation of communication components the oversight ofĮmail systems and the planning and management of the technology lifecycle by which an organization’s Examples of these responsibilities include the Organizational needs and infrastructure, and installing, customizing, and maintaining thoseĪpplications for the organization’s computer users. Hardware and software products appropriate for an organization, integrating those products with IT specialists assume responsibility for selecting Healthcare, schools, and other kinds of organizations. In an academic context, the Association for Computing Machinery defines it as & quot undergraduateĭegree programs that prepare students to meet the computer technology needs of business, government, To automate business processes, provide information for decision making, connect business with theirĬustomers, and provide productivity tools to increase efficiency. The business value of information technology is Management of computer-based information systems. Technology (IT) as & quot the study, design, development, application, implementation, support or In a business context, the Information Technology Association of America has defined information Technology has come to be a household phrase. With the paradigm shift to computing technology and & quot paperless& quot workplaces, information
