Information and communications technology (ICT) is an extensional term for information technology (IT) that stresses the role of unified communicationsand the integration of telecommunications (telephone lines and wireless signals) and computers as per IFGICT, as well as necessary enterprise software, middleware, storage and audiovisual, that enable users to access, store, transmit, understand and manipulate information as per the international federation of ICT.
The term ICT is also used to refer to the convergence of audiovisual and telephone networks with computer networks through a single cabling or link system. There are large economic incentives to merge the telephone network 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 is a broad subject and the concepts are evolving.It covers any product that will store, retrieve, manipulate, transmit, or receive information electronically in a digital form (e.g., personal computers including smartphones, digital television, email, or robots). Theoretical differences between interpersonal-communication technologies and mass-communication technologies have been identified by the philosopher Piyush Mathur. Skills Framework for the Information Age is one of many models for describing and managing competencies for ICT professionals for the 21st century.
The phrase "information and communication technologies" has been used by academic researchers since the 1980s.The abbreviation "ICT" became popular after it was used in a report to the UK government by Dennis Stevenson in 1997, and then in the revised National Curriculum for England, Wales and Northern Ireland in 2000. However, in 2012, the Royal Society recommended that the use of the term "ICT" should be discontinued in British schools "as it has attracted too many negative connotations". From 2014, the National Curriculum has used the word computing, which reflects the addition of computer programming into the curriculum.
Variations of the phrase have spread worldwide. The United Nations has created a "United Nations Information and Communication Technologies Task Force" and an internal "Office of Information and Communications Technology".
The money spent on IT worldwide has been estimated as US$3.8 trillionin 2017 and has been growing at less than 5% per year since 2009. The estimate 2018 growth of the entire ICT is 5%. The biggest growth of 16% is expected in the area of new technologies (IoT, Robotics, AR/VR, and AI).
The 2014 IT budget of the US federal government was nearly $82 billion.IT costs, as a percentage of corporate revenue, have grown 50% since 2002, putting a strain on IT budgets. When looking at current companies' IT budgets, 75% are recurrent costs, used to "keep the lights on" in the IT department, and 25% are the cost of new initiatives for technology development.
The average IT budget has the following breakdown:
The estimate of money to be spent in 2022 is just over US$6 trillion.
The world's technological capacity to store information grew from 2.6 (optimally compressed) exabytes in 1986 to 15.8 in 1993, over 54.5 in 2000, and to 295 (optimally compressed) exabytes in 2007, and some 5 zetta bytes in 2014.This is the informational equivalent to 1.25 stacks of CD-ROM from the earth to the moon in 2007, and the equivalent of 4,500 stacks of printed books from the earth to the sun in 2014. The world's technological capacity to receive information through one-way broadcast networks was 432 exabytes of (optimally compressed) information in 1986, 715 (optimally compressed) exabytes in 1993, 1.2 (optimally compressed) zettabytes in 2000, and 1.9 zettabytes in 2007. The world's effective capacity to exchange information through two-way telecommunication networks was 281 petabytes of (optimally compressed) information in 1986, 471 petabytes in 1993, 2.2 (optimally compressed) exabytes in 2000, 65 (optimally compressed) exabytes in 2007, and some 100 exabytes in 2014. The world's technological capacity to compute information with humanly guided general-purpose computers grew from 3.0 × 10^8 MIPS in 1986, to 6.4 x 10^12 MIPS in 2007.

The ICT Development Index ranks and compares the level of ICT use and access across the various countries around the world.In 2014 ITU (International Telecommunications Union) released the latest rankings of the IDI, with Denmark attaining the top spot, followed by South Korea. The top 30 countries in the rankings include most high-income countries where the quality of life is higher than average, which includes countries from Europe and other regions such as "Australia, Bahrain, Canada, Japan, Macao (China), New Zealand, Singapore, and the United States; almost all countries surveyed improved their IDI ranking this year."
On 21 December 2001, the United Nations General Assembly approved Resolution 56/183, endorsing the holding of the World Summit on the Information Society (WSIS) to discuss the opportunities and challenges facing today's information society.According to this resolution, the General Assembly related the Summit to the United Nations Millennium Declaration's goal of implementing ICT to achieve Millennium Development Goals. It also emphasized a multi-stakeholder approach to achieve these goals, using all stakeholders including civil society and the private sector, in addition to governments.
To help anchor and expand ICT to every habitable part of the world, "2015 is the deadline for achievements of the UN Millennium Development Goals (MDGs), which global leaders agreed upon in the year 2000."
There is evidence that, to be effective in education, ICT must be fully integrated into the pedagogy. Specifically, when teaching literacy and math, using ICT in combination with Writing to Learnproduces better results than traditional methods alone or ICT alone. The United Nations Educational, Scientific and Cultural Organisation (UNESCO), a division of the United Nations, has made integrating ICT into education part of its efforts to ensure equity and access to education. The following, taken directly from a UNESCO publication on educational ICT, explains the organization's position on the initiative.
Information and Communication Technology can contribute to universal access to education, equity in education, the delivery of quality learning and teaching, teachers' professional development and more efficient education management, governance, and administration. UNESCO takes a holistic and comprehensive approach to promote ICT in education. Access, inclusion, and quality are among the main challenges they can address. The Organization's Intersectoral Platform for ICT in education focuses on these issues through the joint work of three of its sectors: Communication & Information, Education and Science.
Despite the power of computers to enhance and reform teaching and learning practices, improper implementation is a widespread issue beyond the reach of increased funding and technological advances with little evidence that teachers and tutors are properly integrating ICT into everyday learning. Intrinsic barriers such as a belief in more traditional teaching practices and individual attitudes towards computers in education as well as the teachers own comfort with computers and their ability to use them all as result in varying effectiveness in the integration of ICT in the classroom.
School environments play an important role in facilitating language learning. However, language and literacy barriers are obstacles preventing refugees from accessing and attending school, especially outside camp settings.
Mobile-assisted language learning apps are key tools for language learning. Mobile solutions can provide support for refugees’ language and literacy challenges in three main areas: literacy development, foreign language learning and translations. Mobile technology is relevant because communicative practice is a key asset for refugees and immigrants as they immerse themselves in a new language and a new society. Well-designed mobile language learning activities connect refugees with mainstream cultures, helping them learn in authentic contexts.
ICT has been employed as an educational enhancement in Sub-Saharan Africa since the 1960s. Beginning with television and radio, it extended the reach of education from the classroom to the living room, and to geographical areas that had been beyond the reach of the traditional classroom. As the technology evolved and became more widely used, efforts in Sub-Saharan Africa were also expanded. In the 1990s a massive effort to push computer hardware and software into schools was undertaken, with the goal of familiarizing both students and teachers with computers in the classroom. Since then, multiple projects have endeavoured to continue the expansion of ICT's reach in the region, including the One Laptop Per Child (OLPC) project, which by 2015 had distributed over 2.4 million laptops to nearly 2 million students and teachers.
The inclusion of ICT in the classroom often referred to as M-Learning, has expanded the reach of educators and improved their ability to track student progress in Sub-Saharan Africa. In particular, the mobile phone has been most important in this effort. Mobile phone use is widespread, and mobile networks cover a wider area than internet networks in the region. The devices are familiar to student, teacher, and parent, and allow increased communication and access to educational materials. In addition to benefits for students, M-learning also offers the opportunity for better teacher training, which leads to a more consistent curriculum across the educational service area. In 2011, UNESCO started a yearly symposium called Mobile Learning Week with the purpose of gathering stakeholders to discuss the M-learning initiative.
Implementation is not without its challenges. While mobile phone and internet use are increasing much more rapidly in Sub-Saharan Africa than in other developing countries, the progress is still slow compared to the rest of the developed world, with smartphone penetration only expected to reach 20% by 2017.Additionally, there are gender, social, and geo-political barriers to educational access, and the severity of these barriers vary greatly by country. Overall, 29.6 million children in Sub-Saharan Africa were not in school in the year 2012, owing not just to the geographical divide, but also to political instability, the importance of social origins, social structure, and gender inequality. Once in school, students also face barriers to quality education, such as teacher competency, training and preparedness, access to educational materials, and lack of information management.
Modern ICT In modern society ICT is ever-present, with over three billion people having access to the Internet.With approximately 8 out of 10 Internet users owning a smartphone, information and data are increasing by leaps and bounds. This rapid growth, especially in developing countries, has led ICT to become a keystone of everyday life, in which life without some facet of technology renders most of clerical, work and routine tasks dysfunctional.
The most recent authoritative data, released in 2014, shows "that Internet use continues to grow steadily, at 6.6% globally in 2014 (3.3% in developed countries, 8.7% in the developing world); the number of Internet users in developing countries has doubled in five years (2009-2014), with two-thirds of all people online now living in the developing world."
However, hurdles are still large. "Of the 4.3 billion people not yet using the Internet, 90% live in developing countries. In the world's 42 Least Connected Countries (LCCs), which are home to 2.5 billion people, access to ICTs remains largely out of reach, particularly for these countries' large rural populations."ICT has yet to penetrate the remote areas of some countries, with many developing countries dearth of any type of Internet. This also includes the availability of telephone lines, particularly the availability of cellular coverage, and other forms of electronic transmission of data. The latest "Measuring the Information Society Report" cautiously stated that the increase in the aforementioned cellular data coverage is ostensible, as "many users have multiple subscriptions, with global growth figures sometimes translating into little real improvement in the level of connectivity of those at the very bottom of the pyramid; an estimated 450 million people worldwide live in places which are still out of reach of mobile cellular service."
Favourably, the gap between the access to the Internet and mobile coverage has decreased substantially in the last fifteen years, in which "2015 [was] the deadline for achievements of the UN Millennium Development Goals (MDGs), which global leaders agreed upon in the year 2000, and the new data show ICT progress and highlight remaining gaps." ICT continues to take on a new form, with nanotechnology set to usher in a new wave of ICT electronics and gadgets. ICT newest editions into the modern electronic world include smartwatches, such as the Apple Watch, smart wristbands such as the Nike+ FuelBand, and smart TVs such as Google TV. With desktops soon becoming part of a bygone era, and laptops becoming the preferred method of computing, ICT continues to insinuate and alter itself in the ever-changing globe.
Information communication technologies play a role in facilitating accelerated pluralism in new social movements today. The internet according to Bruce Bimber is "accelerating the process of issue group formation and action"and coined the term accelerated pluralism to explain this new phenomena. ICTs are tools for "enabling social movement leaders and empowering dictators" in effect promoting societal change. ICTs can be used to garner grassroots support for a cause due to the internet allowing for political discourse and direct interventions with state policy as well as change the way complaints from the populace are handled by governments. Furthermore, ICTs in a household are associated with women rejecting justifications for intimate partner violence. According to a study published in 2017, this is likely because “[a]ccess to ICTs exposes women to different ways of life and different notions about women’s role in society and the household, especially in culturally conservative regions where traditional gender expectations contrast observed alternatives."
Scholar Mark Warschauer defines a “models of access” framework for analyzing ICT accessibility. In the second chapter of his book, Technology and Social Inclusion: Rethinking the Digital Divide, he describes three models of access to ICTs: devices, conduits, and literacy.Devices and conduits are the most common descriptors for access to ICTs, but they are insufficient for meaningful access to ICTs without third model of access, literacy. Combined, these three models roughly incorporate all twelve of the criteria of “Real Access” to ICT use, conceptualized by a non-profit organization called Bridges.org in 2005:
The most straightforward model of access for ICT in Warschauer’s theory is devices.In this model, access is defined most simply as the ownership of a device such as a phone or computer. Warschauer identifies many flaws with this model, including its inability to account for additional costs of ownership such as software, access to telecommunications, knowledge gaps surrounding computer use, and the role of government regulation in some countries. Therefore, Warschauer argues that considering only devices understates the magnitude of digital inequality. For example, the Pew Research Center notes that 96% of Americans own a smartphone, although most scholars in this field would contend that comprehensive access to ICT in the United States is likely much lower than that.
A conduit requires a connection to a supply line, which for ICT could be a telephone line or Internet line. Accessing the supply requires investment in the proper infrastructure from a commercial company or local government and recurring payments from the user once the line is set up. For this reason, conduits usually divide people based on their geographic locations. As a Pew Research Center poll reports, rural Americans are 12% less likely to have broadband access than other Americans, thereby making them less likely to own the devices.Additionally, these costs can be prohibitive to lower-income families accessing ICTs. These difficulties have led to a shift toward mobile technology; fewer people are purchasing broadband connection and are instead relying on their smartphones for Internet access, which can be found for free at public places such as libraries. Indeed, smartphones are on the rise, with 37% of Americans using smartphones as their primary medium for internet access and 96% of Americans owning a smartphone.
In 1981, Sylvia Scribner and Michael Cole studied a tribe in Liberia, the Vai people, that has its own local language. Since about half of those literate in Vai have never had formal schooling, Scribner and Cole were able to test more than 1,000 subjects to measure the mental capabilities of literates over non-literates.This research, which they laid out in their book The Psychology of Literacy, allowed them to study whether the literacy divide exists at the individual level. Warschauer applied their literacy research to ICT literacy as part of his model of ICT access.
Scribner and Cole found no generalizable cognitive benefits from Vai literacy; instead, individual differences on cognitive tasks were due to other factors, like schooling or living environment.The results suggested that there is “no single construct of literacy that divides people into two cognitive camps; [...] rather, there are gradations and types of literacies, with a range of benefits closely related to the specific functions of literacy practices.” Furthermore, literacy and social development are intertwined, and the literacy divide does not exist on the individual level.
Warschauer draws on Scribner and Cole’s research to argue that ICT literacy functions similarly to literacy acquisition, as they both require resources rather than a narrow cognitive skill. Conclusions about literacy serve as the basis for a theory of the digital divide and ICT access, as detailed below:
There is not just one type of ICT access, but many types. The meaning and value of access varies in particular social contexts. Access exists in gradations rather than in a bipolar opposition. Computer and Internet use brings no automatic benefit outside of its particular functions. ICT use is a social practice, involving access to physical artifacts, content, skills, and social support. And acquisition of ICT access is a matter not only of education but also of power.
Therefore, Warschauer concludes that access to ICT cannot rest on devices or conduits alone; it must also engage physical, digital, human, and social resources.Each of these categories of resources have iterative relations with ICT use. If ICT is used well, it can promote these resources, but if it is used poorly, it can contribute to a cycle of underdevelopment and exclusion.
The Information Age is a historical period that began in the mid-20th century, characterized by a rapid epochal shift from the traditional industry established by the Industrial Revolution to an economy primarily based upon information technology. The onset of the Information Age can be associated with the development of transistor technology.
The digital divide refers to the gap who are to benefit from the Digital Age and those who are not. People without access to the Internet and other information and communication technologies are put at a disadvantage, as they are unable or less able to obtain digital information, shop online, participate democratically, or learn and offer skills. This resulted in programs to give computers and related services to people without access.
The global digital divide describes global disparities, primarily between developed and developing countries, in regards to access to computing and information resources such as the Internet and the opportunities derived from such access. As with a smaller unit of analysis, this gap describes an inequality that exists, referencing a global scale.
Freedom of information is freedom of a person or people to publish and consume information. Access to information is the ability for an individual to seek, receive and impart information effectively. This sometimes includes "scientific, indigenous, and traditional knowledge; freedom of information, building of open knowledge resources, including open Internet and open standards, and open access and availability of data; preservation of digital heritage; respect for cultural and linguistic diversity, such as fostering access to local content in accessible languages; quality education for all, including lifelong and e-learning; diffusion of new media and information literacy and skills, and social inclusion online, including addressing inequalities based on skills, education, gender, age, race, ethnicity, and accessibility by those with disabilities; and the development of connectivity and affordable ICTs, including mobile, the Internet, and broadband infrastructures".
M-learning or mobile learning is "learning across multiple contexts, through social and content interactions, using personal electronic devices". A form of distance education, m-learners use mobile device educational technology at their convenient time.
A telecentre is a public place where people can access computers, the Internet, and other digital technologies that enable them to gather information, create, learn, and communicate with others while they develop essential digital skills. Telecentres exist in almost every country, although they sometimes go by a different names including public internet access center (PIAP), village knowledge center, infocenter, Telecottage, Electronic Village Hall, community technology center (CTC), community multimedia center (CMC), multipurpose community telecentre (MCT), Common/Citizen Service Centre (CSC) and school-based telecentre. While each telecentre is different, their common focus is on the use of digital technologies to support community, economic, educational, and social development—reducing isolation, bridging the digital divide, promoting health issues, creating economic opportunities, and reaching out to youth for example.
Technological literacy is the ability to use, manage, understand, and assess technology. Technological literacy is related to digital literacy in that when an individual is proficient in using computers and other digital devices to access the Internet, digital literacy gives them the ability to use the Internet to discover, review, evaluate, create, and use information via various digital platforms, such as web browsers, databases, online journals, magazines, newspapers, blogs, and social media sites.
Digital literacy refers to an individual's ability to find, evaluate, and clearly communicate information through typing and other media on various digital platforms. It is evaluated by an individual's grammar, composition, typing skills and ability to produce text, images, audio and designs using technology. The American Library Association (ALA) defines digital literacy as "the ability to use information and communication technologies to find, evaluate, create, and communicate information, requiring both cognitive and technical skills." While digital literacy initially focused on digital skills and stand-alone computers, the advent of the internet and use of social media, has resulted in the shift in some of its focus to mobile devices. Similar to other expanding definitions of literacy that recognize cultural and historical ways of making meaning, digital literacy does not replace traditional forms of literacy, but instead builds upon and expands the skills that form the foundation of traditional forms of literacy. Digital literacy should be considered to be a part of the path to knowledge.
The knowledge divide is the gap between those who can find, create, manage, process, and disseminate information or knowledge, and those who are impaired in this process. According to a 2005 UNESCO World Report, the rise in the 21st century of a global information society has resulted in the emergence of knowledge as a valuable resource, increasingly determining who has access to power and profit. The rapid dissemination of information on a potentially global scale as a result of new information media and the globally uneven ability to assimilate knowledge and information has resulted in potentially expanding gaps in knowledge between individuals and nations. The digital divide is an extension of the knowledge divide, dividing people who have access to the internet and those who do not. The knowledge divide also represents the inequalities of knowledge among different identities, including but nor limited to race, economic status, and gender.
Mark Warschauer is a professor in the Department of Education and the Department of Informatics at the University of California, Irvine, director of UCI's Ph.D. in Education program and founding director of UCI's Digital Learning Lab. He is the author or editor of eight books and more than 100 scholarly papers on topics related to technology use for language and literacy development, education, and social inclusion.
Information and communication technology in agriculture, also known as e-agriculture, focuses on the enhancement of agricultural and rural development through improved information and communication processes. More specifically, e-agriculture involves the conceptualization, design, development, evaluation and application of innovative ways to use information and communication technologies (ICTs) in the rural domain, with a primary focus on agriculture. ICT includes devices, networks, mobiles, services and applications; these range from innovative Internet-era technologies and sensors to other pre-existing aids such as fixed telephones, televisions, radios and satellites. Provisions of standards, norms, methodologies, and tools as well as development of individual and institutional capacities, and policy support are all key components of e-agriculture.
Information and media literacy (IML) enables people to show and make informed judgments as users of information and media, as well as to become skillful creators and producers of information and media messages in their own right. Renee Hobbs suggests that “few people verify the information they find online ― both adults and children tend to uncritically trust information they find, from whatever source.” People need to gauge the credibility of information and can do so by answering three questions:
The use of new media in Ghana like elsewhere is growing. The Information and Communications Technologies (ICT) sector, which is based on a free market approach, has promoted new media use. Most popular aspects of new media to Ghanaians is the Internet, and its associated mobile and desktop applications for education, health, politics, business, publishing, governance and so on. Also popular is the use of mobile devices like smartphones and tablets and computers.
A knowledge society generates, shares and makes available to all members of the society knowledge that may be used to improve the human condition. A knowledge society differs from an information society in that the former serves to transform information into resources that allow society to take effective action while the latter only creates and disseminates the raw data. The capacity to gather and analyze information has existed throughout human history. However, the idea of the present-day knowledge society is based on the vast increase in data creation and information dissemination that results from the innovation of information technologies. The UNESCO World Report addresses the definition, content and future of knowledge societies.
One of the defining features of development today is the relationship between education and technology, stimulated by the spectacular growth in internet connectivity and mobile penetration. We live in a connected world. An estimated 40% of the world’s population now uses the internet and this number is growing at a remarkable rate. While there are significant variations in internet connectivity among countries and regions, the number of households with such links in the global South has now overtaken those in the global North. Moreover, over 70% of mobile telephone subscriptions worldwide are now in the global South. Five billion people are expected to go from no to full connectivity within the next twenty years. However, there are still significant gaps among countries and regions, for example between urban and rural areas. Limited broadband speed and lack of connectivity hamper access to knowledge, participation in society and economic development.
Educational technology in sub-Saharan Africa refers to the promotion, development and use of information and communication technologies (ICT), m-learning, media, and other technological tools to improve aspects of education in sub-Saharan Africa. Since the 1960s, various information and communication technologies have aroused strong interest in sub-Saharan Africa as a way of increasing access to education, and enhancing its quality and fairness.
The digital divide is an economic and social inequality with regard to access to, use of, or impact of information and communication technologies (ICT). Factors causing the divide can vary depending on the country and culture, as can the potential solutions for minimizing or closing the divide.
Mobile learning for refugees refers to solutions and roles that mobile technology plays in refugees’ informal learning. Educational responses ensures that refugees and displaced populations have access to equitable and inclusive quality education and lifelong learning opportunities. The increased access that refugees have to digital mobile technologies is a source of support for education delivery, administration and support services in refugee contexts.
Gender digital divide is defined as gender biases coded into technology products, technology sector and digital skills education.
