concept of information technology

[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. Technology affects our daily life. As a response t… 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 Basics – What is Information? UNDERSTANDING INFORMATION TECHNOLOGY This handout mainly deals with descriptions of data and information technology (IT) concepts and terminologies. Basic Concepts Of Information Technology (IT) 2. 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. Basics of the information technology Information technology (IT) is a technology which uses computers to gather, process, store, protect, and transfer information. The first three, fitting under the technology category, are generally what most students think of … Basic Concepts of Information Technology, which is the basis for the theoretical test. Access study documents, get answers to your study questions, and connect with real tutors for IFSM 201 : Concepts and Applications of Information Technology at University Of Maryland. 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. There are complex trade-offs among privacy, management control, … Information Technology deals with all the information activities. CONCEPT OF INFORMATION TECHNOLOGY. 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. [9], Electronic computers, using either relays or valves, began to appear in the early 1940s. No-Charge Teleworking Consultations. [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. "[38], Companies in the information technology field are often discussed as a group as the "tech sector" or the "tech industry".[39][40][41]. [24], In recent years, the extensible markup language (XML) has become a popular format for data representation. It also lacked the ability to store its program in memory; programming was carried out using plugs and switches to alter the internal wiring. [10] The first recognisably modern electronic digital stored-program computer was the Manchester Baby, which ran its first program on 21 June 1948. Business firms and other organizations rely on information systems to carry out and manage their operations, interact with their customers and suppliers, and compete in the marketplace. This page was last edited on 14 December 2020, at 23:00. 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. 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. Basic Technology JSS 1, Week: 1. (1986). • Information is data processed for some purpose • Information can only be considered to be 'real' Info if it meets certain criteria i.e. By: Kh Atiar Rahman: A computer is an electrically powered device or set of devices which works under the control of a stored programme. [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. The electromechanical Zuse Z3, completed in 1941, was the world's first programmable computer, and by modern standards one of the first machines that could be considered a complete computing machine. 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. 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… Basic Concepts Of Information Technology (It) 1. IT is typically used within the context of business operations as opposed to personal or entertainment technologies. Several products or services within an economy are associated with information technology, including computer hardware, software, electronics, semiconductors, internet, telecom equipment, and e-commerce.[5][a]. These might include databases or other information repositories. 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. [2] IT is considered to be a subset of information and communications technology (ICT). It is a word of Greek origin, τεχνολογία, It includes all the various activities connected with the location, acquisition, processing, storage and communication of information. [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. [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. In a business context, the Information Technology Association of America has defined information technology as "the study, design, development, application, implementation, support or management of computer-based information systems". 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). Meaning of Technology. Humans have been storing, retrieving, manipulating, and communicating information since the Sumerians in Mesopotamia developed writing in about 3000 BC. 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. Although it was programmable, it was not general-purpose, being designed to perform only a single task. data-at-rest". For the Indian company, see, On the later more broad application of the term IT, Keary comments: "In its original application 'information technology' was appropriate to describe the convergence of technologies with application in the vast field of data storage, retrieval, processing, and dissemination. [COVID-19 Alert] Network Depot is giving back. [3] This article focuses on the most recent period (electronic). (2000) on a practical foundation for informed consent in Internet transactions. 1. [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". This video was created to assist learners in developing a basic understanding of the concept of information technology. * 1. it must… Therefore, if a … Why is it important to understand these technical terms? 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. [19]:6 Most digital data today is still stored magnetically on hard disks, or optically on media such as CD-ROMs. Inspite of our claim that IR is actually documentretrieval, there has throughout the history of the field aproblematic tendency to regard information as pieces of facts oropinion freed from the documents. The Basics – What is Information? Technology is a term that may be new to us but it is describing something which is not new at all. * Information is data processed for some purpose * Information can only be considered to be 'real' Info if it meets certain criteria i.e. 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. 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. 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 ]. 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). Shelly, Gary, Cashman, Thomas, Vermaat, Misty, and Walker, Tim. First, many of these terms come up in later sessions, and therefore need to be understood. These important inventions led to the development of the personal computer (PC) in the 1970s, and the emergence of information and communications technology (ICT). U.S. Employment distribution of computer systems design and related services, 2011[43], U.S. Employment in the computer systems and design related services industry, in thousands, 1990-2011[43], U.S. Occupational growth and wages in computer systems design and related services, 2010-2020[43], U.S. projected percent change in employment in selected occupations in computer systems design and related services, 2010-2020[43], U.S. projected average annual percent change in output and employment in selected industries, 2010-2020[43], The field of information ethics was established by mathematician Norbert Wiener in the 1940s. [23], Database Management Systems (DMS) emerged in the 1960s to address the problem of storing and retrieving large amounts of data accurately and quickly. One difficulty faced by students on many information management courses is the lack of any attempt to teach concepts of information. An early such systems was IBM's Information Management System (IMS),[24] which is still widely deployed more than 50 years later. [27] All databases are common in one point that the structure of the data they contain is defined and stored separately from the data itself, in a database schema. Information is a resource which has no value until it is extracted, processed and utilized. This is the physical technology that works with information. [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.
