Information technology in the context of Amsterdam Science Park

The Internet (or internet) is the global system of interconnected computer networks that uses the Internet protocol suite (TCP/IP) to communicate between networks and devices. It is a network of networks that comprises private, public, academic, business, and government networks of local to global scope, linked by electronic, wireless, and optical networking technologies. The Internet carries a vast range of information services and resources, such as the interlinked hypertext documents and applications of the World Wide Web (WWW), electronic mail, internet telephony, streaming media and file sharing.

Most traditional communication media, including telephone, radio, television, paper mail, newspapers, and print publishing, have been transformed by the Internet, giving rise to new media such as email, online music, digital newspapers, news aggregators, and audio and video streaming websites. The Internet has enabled and accelerated new forms of personal interaction through instant messaging, Internet forums, and social networking services. Online shopping has also grown to occupy a significant market across industries, enabling firms to extend brick and mortar presences to serve larger markets. Business-to-business and financial services on the Internet affect supply chains across entire industries.

Information and communications technology (ICT) is an extensional term for information technology (IT) that stresses the role of unified communications and the integration of telecommunications (telephone lines and wireless signals) and computers, as well as necessary enterprise software, middleware, storage and audiovisual, that enable users to access, store, transmit, understand and manipulate information.

ICT is also used to refer to the convergence of audiovisuals and telephone networks with computer networks through a single cabling or link system. There are large economic incentives to merge the telephone networks with the computer network system using a single unified system of cabling, signal distribution, and management. ICT is an umbrella term that includes any communication device, encompassing radio, television, cell phones, computer and network hardware, satellite systems and so on, as well as the various services and appliances with them such as video conferencing and distance learning. ICT also includes analog technology, such as paper communication, and any mode that transmits communication.

The People's Republic of China has a developing mixed socialist market economy, incorporating industrial policies and strategic five-year plans. China has the world's second-largest economy by nominal GDP and since 2016 has been the world's largest economy when measured by purchasing power parity (PPP). China accounted for 19% of the global economy in 2022 in PPP terms, and around 18% in nominal terms in 2022. The economy consists of state-owned enterprises (SOEs) and mixed-ownership enterprises, as well as a large domestic private sector which contribute approximately 60% of the GDP, 80% of urban employment and 90% of new jobs.

China is the world's largest manufacturing industrial economy and exporter of goods. China is widely regarded as the "powerhouse of manufacturing", "the factory of the world" and the world's "manufacturing superpower". Its production exceeds that of the nine next largest manufacturers combined. However, exports as a percentage of GDP have steadily dropped to just around 20%, reflecting its decreasing importance to the Chinese economy. Nevertheless, it remains the largest trading nation in the world and plays a prominent role in international trade. Manufacturing has been transitioning toward high-tech industries such as electric vehicles, renewable energy, telecommunications and IT equipment, and services has also grown as a percentage of GDP. However, recent research indicates that China’s Total factor productivity (TFP) growth has slowed significantly. IMF estimates show that TFP growth declined from approximately 3.7% in the 2000s to around 1.9% during 2010–2019. Structural reforms and technological progress in manufacturing between 2010 and 2020 contributed only modestly to productivity gains. Additionally, a 2024–2025 IMF working paper finds that factor misallocation resulting from industrial and regulatory policies implemented since the early 2010s reduces China’s aggregate TFP by roughly 1.2% annually. IMF research suggests that while China’s state-led push for high-tech self-reliance since 2013 has supported rapid innovation, it has been accompanied by efficiency losses. Policy measures, including targeted state subsidies appear to favor politically connected firms, crowd out competition, and lead to overcapacity, undermining overall productivity. China is the world's largest high technology exporter. As of 2023, the country spends around 2.6% of GDP to advance research and development across various sectors of the economy. It is also the world's second-largest importer of goods. China is a net importer of services products.

In product development, an end user (sometimes end-user) is a person who ultimately uses or is intended to ultimately use a product. The end user stands in contrast to users who support or maintain the product, such as sysops, system administrators, database administrators, information technology (IT) experts, software professionals, and computer technicians. End users typically do not possess the technical understanding or skill of the product designers, a fact easily overlooked and forgotten by designers: leading to features creating low customer satisfaction. In information technology, end users are not customers in the usual sense—they are typically employees of the customer. For example, if a large retail corporation buys a software package for its employees to use, even though the large retail corporation was the customer that purchased the software, the end users are the employees of the company, who will use the software at work.

Risk is the possibility of something bad happening, comprising a level of uncertainty about the effects and implications of an activity, particularly negative and undesirable consequences.

Risk theory, assessment, and management are applied but substantially differ in different practice areas, such as business, economics, environment, finance, information technology, health, insurance, safety, security, and privacy. The international standard for risk management, ISO 31000, provides general guidelines and principles on managing risks faced by organizations.

Science fiction (often shortened to sci-fi or abbreviated SF) is the genre of speculative fiction that imagines advanced and futuristic scientific or technological progress. The elements of science fiction have evolved over time: from space exploration, extraterrestrial life, time travel, and robotics; to parallel universes, dystopian societies, and biological manipulations; and, most lately, to information technology, transhumanism (and posthumanism), and environmental challenges. Science fiction often specifically explores human responses to the consequences of these types of projected or imagined scientific advances.

The precise definition of science fiction has long been disputed among authors, critics, scholars, and readers. It contains many subgenres, including hard science fiction, which emphasizes scientific accuracy, and soft science fiction, which focuses on social sciences. Other notable subgenres are cyberpunk, which explores the interface between technology and society; climate fiction, which addresses environmental issues; and space opera, which emphasizes pure adventure in a universe in which space travel is common.

In information technology, lossy compression or irreversible compression is the class of data compression methods that uses inexact approximations and partial data discarding to represent the content. These techniques are used to reduce data size for storing, handling, and transmitting content. Higher degrees of approximation create coarser images as more details are removed. This is opposed to lossless data compression (reversible data compression) which does not degrade the data. The amount of data reduction possible using lossy compression is much higher than using lossless techniques.

Well-designed lossy compression technology often reduces file sizes significantly before degradation is noticed by the end-user. Even when noticeable by the user, further data reduction may be desirable (e.g., for real-time communication or to reduce transmission times or storage needs). The most widely used lossy compression algorithm is the discrete cosine transform (DCT), first published by Nasir Ahmed, T. Natarajan and K. R. Rao in 1974.

The World Wide Web (also known as WWW, W3, or simply the Web) is an information system that enables content sharing over the Internet through user-friendly ways meant to appeal to users beyond IT specialists and hobbyists. It allows documents and other web resources to be accessed over the Internet according to specific rules of the Hypertext Transfer Protocol (HTTP).

The Web was invented by English computer scientist Tim Berners-Lee while at CERN in 1989 and opened to the public in 1993. It was conceived as a "universal linked information system". Documents and other media content are made available to the network through web servers and can be accessed by programs such as web browsers. Servers and resources on the World Wide Web are identified and located through a character string called uniform resource locator (URL).

Computing is any goal-oriented activity requiring, benefiting from, or creating computing machinery. It includes the study and experimentation of algorithmic processes, and the development of both hardware and software. Computing has scientific, engineering, mathematical, technological, and social aspects. Major computing disciplines include computer engineering, computer science, cybersecurity, data science, information systems, information technology, and software engineering.

The term computing is also synonymous with counting and calculating. In earlier times, it was used in reference to the action performed by mechanical computing machines, and before that, to human computers.

The Information Age is a historical period that began in the mid-20th century. It is characterized by a rapid shift from traditional industries, as established during the Industrial Revolution, to an economy centered on information technology. The onset of the Information Age has been linked to the development of the transistor in 1947. This technological advance has had a significant impact on the way information is processed and transmitted.

According to the United Nations Public Administration Network, the Information Age was formed by capitalizing on computer miniaturization advances, which led to modernized information systems and internet communications as the driving force of social evolution.

Haryana (Hindi: Hariyāṇā, pronounced [ɦəɾɪːˈaːɳɑɐː]) is a state located in the northwestern part of India. It was carved out after the linguistic reorganisation of Punjab on 1 November 1966. It is ranked 21st in terms of area, with less than 1.4% (44,212 km or 17,070 sq mi) of India's land area. The state capital is Chandigarh, which it shares with the neighbouring state of Punjab; the most populous city is Faridabad, a part of the National Capital Region. The city of Gurgaon is among India's largest financial and technology hubs. Haryana has 6 administrative divisions, 22 districts, 72 sub-divisions, 93 revenue tehsils, 50 sub-tehsils, 140 community development blocks, 154 cities and towns, 7,356 villages, and 6,222 villages panchayats.

Haryana contains 32 special economic zones (SEZs), mainly located within the industrial corridor projects connecting the National Capital Region. Gurgaon is considered one of the major information technology and automobile hubs of India. Haryana ranks 11th among Indian states in human development index. The economy of Haryana is the 13th largest in India, with a gross state domestic product (GSDP) of ₹7.65 trillion (US$90 billion) and has the country's 5th-highest GSDP per capita of ₹240,000 (US$2,800).

In organizational studies, resource management is the efficient and effective development of an organization's resources when they are needed. Such resources may include the financial resources, inventory, human skills, production resources, or information technology (IT) and natural resources.

In the realm of project management, processes, techniques and philosophies as to the best approach for allocating resources have been developed. These include discussions on functional vs. cross-functional resource allocation as well as processes espoused by organizations like the Project Management Institute (PMI) through their Project Management Body of Knowledge (PMBOK) methodology of project management. Resource management is a key element to activity resource estimating and project human resource management. Both are essential components of a comprehensive project management plan to execute and monitor a project successfully. As is the case with the larger discipline of project management, there are resource management software tools available that automate and assist the process of resource allocation to projects and portfolio resource transparency including supply and demand of resources.

A white-collar worker is a person who performs knowledge-based, aptitude-based, managerial, or administrative work generally performed in an office or similar setting. White-collar workers include job paths related to banking, finance, compliance, legal, risk management, internal audit, data privacy, cybersecurity, insurance, government, consulting, academia, accountancy, business and executive management, customer support, design, economics, science, technology, engineering, market research, human resources, operations research, marketing, public relations, real estate, information technology, networking, healthcare, architecture, and research and development.

In contrast, blue-collar workers perform manual labor or work in skilled trades; pink-collar workers work in care, health care, social work, or teaching; green-collar workers specifically work in the environmental sector; and grey-collar jobs combine manual labor and skilled trades with non-manual or managerial duties.

The National Institute of Standards and Technology (NIST) is an agency of the United States Department of Commerce whose mission is to promote American innovation and industrial competitiveness. NIST's activities are organized into physical science laboratory programs that include nanoscale science and technology, engineering, information technology, neutron research, material measurement, and physical measurement. From 1901 to 1988, the agency was named the National Bureau of Standards.

The quaternary sector of the economy is based upon the economic activity that is associated with either the intellectual or knowledge-based economy. This consists of information technology; media; research and development; information-based services such as information-generation and information-sharing; and knowledge-based services such as consultation, entertainment, broadcasting, mass media, telecommunication, education, information technology, financial planning, blogging, and designing.Other definitions describe the quaternary sector as pure services. This may consist of the entertainment industry, to describe media and culture, and government. This may be classified into an additional quinary sector.

The term reflects the analysis of the three-sector model of the economy, in which the primary sector produces raw materials used by the secondary sector to produce goods, which are then distributed to consumers by the tertiary sector.

Service economy can refer to one or both of two recent economic developments:

• The increased importance of the service sector in industrialized economies. The current list of Fortune 500 companies contains more service companies and fewer manufacturers than in previous decades.
• The relative importance of service in a product offering. The service economy in developing countries is mostly concentrated in financial services, hospitality, retail, health, human services, information technology and education. Products today have a higher service component than in previous decades. In the management literature this is referred to as the servitization of products or a product-service system. Virtually every product today has a service component to it.

The old dichotomy between product and service has been replaced by a Service (economics) service–product continuum [1]. Many products are being transformed into services.
