concept of information technology

The first way I describe information systems to students is to tell them that they are made up of five components: hardware, software, data, people, and process. Information is a resource which has no value until it is extracted, processed and utilized. [8] Comparable geared devices did not emerge in Europe until the 16th century, and it was not until 1645 that the first mechanical calculator capable of performing the four basic arithmetical operations was developed. Information technology (IT) is the use of any computers, storage, networking and other physical devices, infrastructure and processes to create, process, store, secure and exchange all forms of electronic data. It is a word of Greek origin, τεχνολογία, Topic: Concept of Technology. Information Technology deals with all the information activities. These important inventions led to the development of the personal computer (PC) in the 1970s, and the emergence of information and communications technology (ICT). [3] This article focuses on the most recent period (electronic). The Basics – What is Information? In 1981, the first commercially available relational database management system (RDBMS) was released by Oracle. IT is considered to be a subset of information and communications technology (ICT). Introduction: The emergence of ICT is one of the wonderful gifts of modern science and technology which has brought tremendous changes in library and information science. [44]:9 Some of the ethical issues associated with the use of information technology include:[45]:20–21, "Infotech" redirects here. [4], The term is commonly used as a synonym for computers and computer networks, but it also encompasses other information distribution technologies such as television and telephones. As a response t… Therefore, if a … A 1958 article in Harvard Business Review referred to information technology as consisting of three basic parts: computational data processing, decision support, and business software. Inthe literature of IS there is a distinction betweendocument retrieval and fact retrieval. Read chapter Concepts of Information Security: ... As the congressional Office of Technology Assessment has noted, the effects of computer-based monitoring depend on the way it is used (OTA, 1987a). [24], In recent years, the extensible markup language (XML) has become a popular format for data representation. * Information is data processed for some purpose * Information can only be considered to be 'real' Info if it meets certain criteria i.e. Information technology (IT) is the use of computers to store, retrieve, transmit, and manipulate data[1] or information. [34], Hilbert and Lopez identify the exponential pace of technological change (a kind of Moore's law): machines' application-specific capacity to compute information per capita roughly doubled every 14 months between 1986 and 2007; the per capita capacity of the world's general-purpose computers doubled every 18 months during the same two decades; the global telecommunication capacity per capita doubled every 34 months; the world's storage capacity per capita required roughly 40 months to double (every 3 years); and per capita broadcast information has doubled every 12.3 years. [10] The first recognisably modern electronic digital stored-program computer was the Manchester Baby, which ran its first program on 21 June 1948. This video was created to assist learners in developing a basic understanding of the concept of information technology. (1986). Website Powered by 321 Web Marketing. [25] IMS stores data hierarchically,[24] but in the 1970s Ted Codd proposed an alternative relational storage model based on set theory and predicate logic and the familiar concepts of tables, rows and columns. This time period marked the beginning of IT as an officially defined … [12], Several later breakthroughs in semiconductor technology include the integrated circuit (IC) invented by Jack Kilby at Texas Instruments and Robert Noyce at Fairchild Semiconductor in 1959, the metal-oxide-semiconductor field-effect transistor (MOSFET) invented by Mohamed Atalla and Dawon Kahng at Bell Laboratories in 1959, and the microprocessor invented by Ted Hoff, Federico Faggin, Masatoshi Shima and Stanley Mazor at Intel in 1971. "[38], Companies in the information technology field are often discussed as a group as the "tech sector" or the "tech industry".[39][40][41]. It also lacked the ability to store its program in memory; programming was carried out using plugs and switches to alter the internal wiring. [18], IBM introduced the first hard disk drive in 1956, as a component of their 305 RAMAC computer system. This page was last edited on 14 December 2020, at 23:00. They typically contain data extracted from various sources, including external sources such as the Internet, organized in such a way as to facilitate decision support systems (DSS). That place notation is equivalent to computationally trading space and time (economical representation of decimal versus long binary strings). Meaning of Technology. [15] The first random-access digital storage device was the Williams tube, based on a standard cathode ray tube,[16] but the information stored in it and delay line memory was volatile in that it had to be continuously refreshed, and thus was lost once power was removed. [14] Electronic data storage, which is used in modern computers, dates from World War II, when a form of delay line memory was developed to remove the clutter from radar signals, the first practical application of which was the mercury delay line. Previous work in informed consent concepts in an information technology context includes work by Friedman et al. [20]:4–5 Until 2002 most information was stored on analog devices, but that year digital storage capacity exceeded analog for the first time. Basic Concepts of Information Technology, which is the basis for the theoretical test. We see its effect around us every day, even though we may not know what it is. Without these backbones of business, it would be impossible for most companies to operate. • Information is data processed for some purpose • Information can only be considered to be 'real' Info if it meets certain criteria i.e. Hardware can be as small as a smartphone that fits in a pocket or as large as a supercomputer that fills a building. Humans have been storing, retrieving, manipulating, and communicating information since the Sumerians in Mesopotamia developed writing in about 3000 BC. These might include databases or other information repositories. IT is typically used within the context of business operations as opposed to personal or entertainment technologies. * 1. it must… Although it was programmable, it was not general-purpose, being designed to perform only a single task. Information system, an integrated set of components for collecting, storing, and processing data and for providing information, knowledge, and digital products. Information and communications technology (ICT) refers to all the technology used to handle telecommunications, broadcast media, intelligent building management systems, audiovisual processing and transmission systems, and network-based control and monitoring functions. Information technology management includes many of the basic functions of management, such as staffing, organizing, budgeting and control, but it also has functions that are unique to IT, such as software development, change management, network planning and tech support. Friedman's work on implementing Value-Sensitive Design 3.1 in the Mozilla Web browser uses the value of informed consent as the focus for the project [ Friedman & Howe, 2002 ]. [32]:4–6, Data transmission has three aspects: transmission, propagation, and reception. Their definition consists of three categories: techniques for processing, the application of statistical and mathematical methods to decision-making, and the simulation of higher-order thinking through computer programs. Fundamental Information Technology Ideas Concept descriptions Binary: that switches have the ability to represent any numeral. UNDERSTANDING INFORMATION TECHNOLOGY This handout mainly deals with descriptions of data and information technology (IT) concepts and terminologies. [23], Database Management Systems (DMS) emerged in the 1960s to address the problem of storing and retrieving large amounts of data accurately and quickly. [22], Massive amounts of data are stored worldwide every day, but unless it can be analysed and presented effectively it essentially resides in what have been called data tombs: "data archives that are seldom visited". ", "Format" refers to the physical characteristics of the stored data such as its. Devices have been used to aid computation for thousands of years, probably initially in the form of a tally stick. 1. We shall call it information technology (IT)." Colossus, developed during the Second World War to decrypt German messages, was the first electronic digital computer. The Basics – What is Information? [33] It can be broadly categorized as broadcasting, in which information is transmitted unidirectionally downstream, or telecommunications, with bidirectional upstream and downstream channels. Concepts and Applications of Information Technology IFSM 201 | 3 Credits (Access to a standard office productivity package, i.e., word processing, spreadsheet, database, and presentation software, required.) IT specialists assume responsibility for selecting hardware and software products appropriate for an organization, integrating those products with organizational needs and infrastructure, and installing, customizing, and maintaining those applications for the organization’s computer users. [13], Early electronic computers such as Colossus made use of punched tape, a long strip of paper on which data was represented by a series of holes, a technology now obsolete. Based on the storage and processing technologies employed, it is possible to distinguish four distinct phases of IT development: pre-mechanical (3000 BC – 1450 AD), mechanical (1450–1840), electromechanical (1840–1940), and electronic (1940–present). An information technology system (IT system) is generally an information system, a communications system or, more specifically speaking, a computer system – including all hardware, soft… It automatically receives data, process data and by controlling the whole process of … This useful conceptual term has since been converted to what purports to be of great use, but without the reinforcement of definition ... the term IT lacks substance when applied to the name of any function, discipline, or position. [COVID-19 Alert] Network Depot is giving back. The earliest form of non-volatile computer storage was the magnetic drum, invented in 1932[17] and used in the Ferranti Mark 1, the world's first commercially available general-purpose electronic computer. An early such systems was IBM's Information Management System (IMS),[24] which is still widely deployed more than 50 years later. In this module you can learn about different parts of a computer, as well as some of the key concepts of Information and Communication Technology (ICT), such as those relating to networks and security: – Understand what hardware is, know about factors that affect computer performance and know about the peripheral devices. THE CONCEPT OF INFORMATION TECHNOLOGY. It includes all the various activities connected with the location, acquisition, processing, storage and communication of information. Basic Concepts Of Information Technology (IT) Dheeraj Mehrotra www.computerscienceexpertise.com (1999). There are complex trade-offs among privacy, management control, … [11], The development of transistors in the late 1940s at Bell Laboratories allowed a new generation of computers to be designed with greatly reduced power consumption. Information technology definition is - the technology involving the development, maintenance, and use of computer systems, software, and networks for the processing and distribution of data. [26], All DMS consist of components, they allow the data they store to be accessed simultaneously by many users while maintaining its integrity. There are several answers. By comparison, the first transistorized computer developed at the University of Manchester and operational by November 1953, consumed only 150 watts in its final version. The first commercially available stored-program computer, the Ferranti Mark I, contained 4050 valves and had a power consumption of 25 kilowatts. Webster, Frank, and Robins, Kevin. (2000) on a practical foundation for informed consent in Internet transactions. The terms "data" and "information" are not synonymous. CONCEPT OF INFORMATION TECHNOLOGY. Management information systems are computer-based methods of arranging information in a cohesive, coherent fashion. data-at-rest". The Joint Task Force for Computing Curricula 2005. information and communications technology, metal-oxide-semiconductor field-effect transistor, Information Technology Association of America, Center for Minorities and People with Disabilities in Information Technology, Information and communications technology, Journal of Cases on Information Technology, List of the largest information technology companies, World Information Technology and Services Alliance, "Free on-line dictionary of computing (FOLDOC)", "Advanced information on the Nobel Prize in Physics 2000", "Early computers at Manchester University", "How Much Information Is There in the World? Typically, IT is used in the context of enterprise operations … [2] IT is considered to be a subset of information and communications technology (ICT). [28] As an evolution of the Standard Generalized Markup Language (SGML), XML's text-based structure offers the advantage of being both machine and human-readable.[29]. Definitions and concepts of technology Definition of technology Technology is the set of technical knowledge, scientifically, ordered that allow you to design and create goods and services that facilitate the adaptation to the environment and meet both their essential needs as people's wishes. Who Should Attend Anyone who is interested to get knowledge in Computers Pre-requisites General knowledge in computer Objective Basic Concepts of Information Technology requires the… As of 2007 almost 94% of the data stored worldwide was held digitally:[21] 52% on hard disks, 28% on optical devices and 11% on digital magnetic tape. No-Charge Teleworking Consultations. … Why is it important to understand these technical terms? Although XML data can be stored in normal file systems, it is commonly held in relational databases to take advantage of their "robust implementation verified by years of both theoretical and practical effort". The basic concept of Information Technology can be traced to the World War II alliance of the military and industry in the development of electronics, computers, and information theory. One difficulty faced by students on many information management courses is the lack of any attempt to teach concepts of information. After the 1940s, the military remained the major source of research and development funding for the expansion of automation to replace manpower with machine power. The module consists of eight categories and the test will contain questions from all of the categories. IT is typically used within the context of business operations as opposed to personal or entertainment technologies. Hardware also includes the peripheral devices that work with computers, such as keyboards, external disk drives, and routers. It has been estimated that the worldwide capacity to store information on electronic devices grew from less than 3 exabytes in 1986 to 295 exabytes in 2007,[22] doubling roughly every 3 years. An information technology system (IT system) is generally an information system, a communications system, or, more specifically speaking, a computer system – including all hardware, software, and peripheral equipment – operated by a limited group of users. Technology affects our daily life. [35] To address that issue, the field of data mining – "the process of discovering interesting patterns and knowledge from large amounts of data"[36] – emerged in the late 1980s. [42][page needed] The responsibilities of those working in the field include network administration, software development and installation, and the planning and management of an organization's technology life cycle, by which hardware and software are maintained, upgraded and replaced.
