Cloud Computing

Cloud computing is a type of Internet-based computing that provides shared computer processing resources and data to computers and other devices on demand. It is a model for enabling ubiquitous, on-demand access to a shared pool of configurable computing resources (e.g., computer networks, servers, storage, applications and services), which can be rapidly provisioned and released with minimal management effort. Cloud computing and storage solutions provide users and enterprises with various capabilities to store and process their data in third-party data centers that may be located far from the user–ranging in distance from across a city to across the world. Cloud computing relies on sharing of resources to achieve coherence and economy of scale, similar to a utility (like the electricity grid) over an electricity network.

Integrated Circuit (IC)

An integrated circuit (IC), sometimes called a chip or microchip, is a semiconductor wafer on which thousands or millions of tiny resistors, capacitors, and transistors are fabricated. An IC can function as an amplifier, oscillator, timer, counter, computer memory, or microprocessor. A particular IC is categorized as either linear (analog) or digital, depending on its intended application.

Linear ICs have continuously variable output (theoretically capable of attaining an infinite number of states) that depends on the input signal level. As the term implies, the output signal level is a linear function of the input signal level. Ideally, when the instantaneous output is graphed against the instantaneous input, the plot appears as a straight line. Linear ICs are used as audio-frequency (AF) and radio-frequency (RF) amplifiers. The operational amplifier(op amp) is a common device in these applications.

Digital ICs operate at only a few defined levels or states, rather than over a continuous range of signal amplitudes. These devices are used in computers, computer networks, modems, and frequency counters. The fundamental building blocks of digital ICs are logic gates, which work with binary data, that is, signals that have only two different states, called low (logic 0) and high (logic 1).

Our world is full of integrated circuits. You find several of them in computers. For example, most people have probably heard about the microprocessor. The microprocessor is an integrated circuit that processes all information in the computer. It keeps track of what keys are pressed and if the mouse has been moved. It counts numbers and runs programs, games and the operating system. Integrated circuits are also found in almost every modern electrical device such as cars, television sets, CD players, cellular phones, etc. But what is an integrated circuit and what is the history behind it?

Transistor

A transistor computer is a computer which uses discrete transistors instead of vacuum tubes. The "first generation" of electronic computers used vacuum tubes, which generated large amounts of heat, were bulky, and were unreliable. A "second generation" of computers, through the late 1950s and 1960s featured boards filled with individual transistors and magnetic memory cores (see History of computing hardware). These machines remained the mainstream design into the late 1960s, when integrated circuits started appearing and led to the "third generation" machines.

Vacuum Tube

Alternatively referred to as an electron tube or valve and first developed by John Ambrose Fleming in 1904. The vacuum tube is a glass tube that has its gas removed which creates a vacuum. Vacuum tubes contain electrodes for controlling electron flow in early computers that used them as a switch or an amplifier. The picture shows a collection of different vacuum tubes to give you a better understanding.

Today, vacuum tubes are no longer used with computers and have been replaced by the transistor.

Artificial Intelligence (AI)

Artificial intelligence (AI) is the intelligence exhibited by machines or software. It is also the name of the academic field of study which studies how to create computers and computer software that are capable of intelligent behavior.
History
"machines will be capable, within 20 years, of doing any work a man can do." Two years later, MIT researcher Marvin Minsky predicted, "Within a generation ... the problem of creating 'artificial intelligence' will substantially be solved."
(artificial intelligence innovator Herbert Simon.1965)
Definition
     Artificial intelligence (AI) is the intelligence of machines and the branch of computer science which aims to create it
     Artificial intelligence (AI) is the intelligence of machines and the branch of computer science which aims to create it
Comparisons between human and computer intelligence
Image result for artificial intelligence
Normal humans have the same intellectual mechanisms and that differences in intelligence are related to ``quantitative biochemical and physiological conditions' , but computer programs have plenty of speed and memory but their abilities correspond to the intellectual mechanisms that program designers understand well enough to put in programs.
Whenever people do better than computers on some task or computers use a lot of computation to do as well as people, this demonstrates that the program designers lack understanding of the intellectual mechanisms required to do the task efficiently.
Motivation
Why Artificial Intelligence?
  Computers are fundamentally well suited to performing mechanical computations, using fixed programmed rules.
    Artificial machines perform simple monotonous tasks efficiently and reliably, which humans are ill-suited to.
   For more complex problems, things get more difficult... Unlike humans, computers have trouble understanding specific situations, and adapting to new situations.
         Artificial Intelligence aims to improve machine behavior in tackling such complex tasks.
   Humans have an interesting approach to problem-solving, based on abstract thought, high-level deliberative reasoning and pattern recognition.
        AI research is allowing us to understand our intelligent behavior.
       Artificial Intelligence can help us understand this process by recreating it, then potentially enabling us to enhance it beyond our current capabilities.
Limitations
        When will Computers become truly intelligent?
      To date, all the traits of human intelligence have not been captured and applied together to spawn an intelligent artificial creature. 
        Currently, Artificial Intelligence rather seems to focus on lucrative domain specific applications, which do not necessarily require the full extent of AI capabilities.
     There is little doubt among the community that artificial machines will be capable of intelligent thought in the near future.
Technology
     How does Artificial Intelligence work?
   There are many different approaches to Artificial Intelligence. Some are obviously more suited than others in some cases.
   Over the past five decades, AI research has mostly been focusing on solving specific problems. Numerous solutions have been devised and improved to do so efficiently and reliably.
   This explains why the field of Artificial Intelligence is split into many branches, ranging from Pattern Recognition to Artificial Life, including Evolutionary Computation and Planning.
Advantage
         it can help improve our way of life
         machines will be able to do jobs that require detailed instructions
         mental alertness and decision making capabilities
         use robots for heavy construction, military benefits, or even for personal assistance at private homes
         there will be less injuries and stress to human beings
     Many of our health problems now have possible solutions with the use of Artificial Intelligence in studies at universities
          scientists have been using AI to test theories and notions about how our brains work
          AI opens up new and exciting avenues for entertainment possibilities.
      AI also makes interactive electronic games more fun by making the computer controlled characters more realistic and human-like.
Applications
Image result for applications of artificial intelligence
          game playing
There is some AI in them and they play well against people
          speech recognition
instruct some computers using speech
          understanding natural language
The computer has to be provided with a understanding of the domain the text is about, and this is presently possible only for very limited domains.
          expert systems
One of the first expert systems was MYCIN in 1974, which diagnosed bacterial infections of the blood and suggested treatments. It did better than medical students or practicing doctors, provided its limitations were observed.The usefulness of current expert systems depends on their users having common sense

Artificial intelligence and Learning
Using Artificial intelligence (AI) help instructional designers to provide creative solutions ,  problem solving strategies and more interactivity in the learning  .
For example , Games :

The games provide interactive learning environment for learners .The intelligence is necessary in computer games when players are competing against other characters which are played by the computer. Most people enjoy playing against other people rather than a machine because other people can provide variable, random and sometimes unpredictable responses and behaviors, whereas simply programmed machines will always respond the same way, in predictable ways that mean a player only has to remember the few basic responses possible, and respond to them in order to complete the level.

Vacuum Tube

A vacuum tube (also called a VT,  electron tube or, in the UK, a valve ) is a device sometimes used to amplify electronic signals. In most applications, the vacuum tube is obsolete, having been replaced decades ago by the bipolar transistor and, more recently, by the field-effect transistor . However, tubes are still used in some high-power amplifiers, especially at microwave radio frequencies and in some hi-fi audio systems.
                  vacuum tube
                source: wikipedia
Tubes operate at higher voltages than transistors. A typical transistorized amplifier needs 6 to 12 volts to function; an equivalent tube type amplifier needs 200 to 400 volts. At the highest power levels, some tube circuits have power supplies delivering several kilovolts.
Vacuum tubes are making a comeback among audiophiles who insist that tubes deliver better audio quality than transistors. These old-fashioned components are more electrically rugged than their solid-state counterparts; a tube can often withstand temporary overload conditions and power-line transients that would instantly destroy a transistor.
The major disadvantages of tubes include the fact that they require bulky power supplies, and the high voltages can present an electric shock hazard.

Digital Literacy: be savvy for better achievement


Digital Literacy is the ability to use information and communication technologies to find, evaluate, create, and communicate information, requiring both cognitive and technical skills.
Knowledge, skills, and behaviours used in a broad range of digital devices such as smartphones, tabletslaptops and desktop PCs, all of which are seen as network rather than computing devices is called digital literacy. Digital literacy initially focused on digital skills and stand-alone computers, but the focus has moved from stand-alone to network devices. Digital literacy is distinct from computer literacy and digital skills. Computer literacy preceded digital literacy, and refers to knowledge and skills in using traditional computers (such as desktop PCs and laptops) with a focus on practical skills in using software application packages. Digital skills is a more contemporary term but is limited to practical abilities in using digital devices like; laptops and smartphones.
                 Source: images.google.com
A digitally literate person will possess a range of digital skills, knowledge of the basic principles of computing devices, skills in using computer networks, an ability to engage in online communities and social networks while adhering to behavioural protocols, be able to find, capture and evaluate information, an understanding of the societal issues raised by digital technologies and possess critical thinking skills.
Digital literacy does not replace traditional forms of literacy. It builds upon the foundation of traditional forms of literacy.Digital literacy is the marrying of the two terms digital and literacy; however, it is much more than a combination of the two terms. Digital information is a symbolic representation of data, and literacy refers to the ability to read for knowledge, write coherently, and think critically about the written word.
Digital literacy researchers explore a wide variety of topics, including how people find, use, summarize, evaluate, create, and communicate information while using digital technologies. Research also encompasses a variety of hardware platforms, such as computer hardwarecell phones and other mobile devices and software or applications, including web search or Internet applications more broadly. As a result, the area is concerned with much more than how people learn to use computers. In Scandinavian English as well as in OECD(Centre for Educational Research and Innovation) research, the term Digital Competence is preferred over literacy due to its holistic use. In 2013, European Commission published a Digital Competence Framework which also includes the notion of digital literacy, but goes further than that, for example, defining problem solving in digital environments as part of the Digital competences.
Academic and pedagogical concepts
From a competency perspective, literacy is the lowest level in a progression that spans literacy, fluency and mastery. From an academic perspective, digital literacy is a part of the computing subject area, alongside computer science andinformation technology.

It is a new literacy, and may it be decomposed into several sub-literacies. One such decomposition considers digital literacy as embracing computer literacynetwork literacyinformation literacy and social media literacy. Previous conceptualisations of digital literacy focused on the practical skills associated with using computers. These include hardware skills, such as connecting devices, and software skills, such as using application packages. Contemporary conceptualisations of digital literacy add to these traditional skills, and embrace knowledge, skills, attitudes and behaviours, particularly with respect to networked devices. Digital literacy differs from computer literacy in a number of significant ways. While it embraces the practical skills that computer literacy incorporates, there is a much greater focus on sociological, political, cultural, economic and behavioural aspects of digital technologies.
As a pedagogical approach in curriculum design, the implementation of digital literacy affords far-reaching advantages. The Internet is both a source of information and communication that has increased exponentially internationally. Subsequently, integrating technology into the classroom in a meaningful way exposes students to a range of literacy practices called multi-literacies which broadens their outlook and widens vistas of information and knowledge which is highly constructive. This methodology embraces the constructivist theory of learning wherein learners draw from their existing knowledge in order to construct new learning.
Core elements and their educational effects
Literacies can be grouped together in what is known as the Essential Elements of Digital Literacies which expounds the theory that having an understanding of these eight essential elements of digital literacies will enable an individual to be digitally literate. The eight elements are Cultural, Cognitive, Constructive, Communicative, Confidence, Creative, Critical and Civic. The value of each of these core elements is dependent on varying needs at different times.
It is recognized that the implementation of these elements in an individual context will require constant updating and upgrading as digital information and tools change along with our understanding of them.

From a pedagogical perspective, digital literacy seeks to include knowledge and understanding of the applications and implications of digital technologies, in contrast to the skills focus of computer literacy. Digital literacy is considered a key aspect of contemporary citizenship to enable individuals to fully participate in the digital economy and the democratic process, and knowledgeably engage with debates relating to the networked society, such as those relating to personal privacy. Digital literacy may be studied at a number of levels. While fundamental concepts and skills are normally covered in the lower levels of national qualification frameworks, more advanced treatments, dealing with more sophisticated concepts and skills such as critical thinking, are higher level competencies.Now a days new literacy, Layered literacy, Transliteracy, Electracy, and Digital citizen grooming with digital literacy. 
Digital and media literacy
Source: examiner.com 
Digital literacy informs Communities sustaining democratic movements in the digital age.  Technology, economic and behavioral changes are dramatically altering how people communicate and move towards. In this age, information is more fragmented. Communications systems no longer runalong the same lines as local governance. The gap in access to digital tools and skills is wide and troubling. This new era poses major challenges to the flow of news and information. people depend on to manage their complex lives. Digital and media literacy is seen as a constellation of life skills that are necessary for full participation in our media-saturated, information-rich society.
Digital Literacy in this Era
Digital literacy requires certain skill sets that are interdisciplinary in nature. Worshiper and Matuchniak list information, media, and technology; learning and innovation skills; and life and career skills as the three skills sets that individuals need to master in order to be digitally literate, or the 21st century skills. In order to achieve information, media, and technology skills, one needs to achieve competency in information literacy, media literacy and ICT (information communication technologies). Encompassed within Learning and Innovation Skills, one must also be able to be exercise their creativity and innovation, critical thinking and problem solving, and communication and collaboration skills (4Cs). In order to be competent in Life and Career Skills, it is also necessary to be able to exercise flexibility and adaptability, initiative and self-direction, social and cross-cultural skills, productivity and accountability, leadership and responsibility.  Aviram & Eshet-Alkalai contend that there are five types of literacies that are encompassed in the umbrella term that is digital literacy.
1.     Photo-visual literacy is the ability to read and deduce information from visuals.
2.     Reproduction literacy is the ability to use digital technology to create a new piece of work or combine existing pieces of work together to make it your own.
3.     Branching literacy is the ability to successfully navigate in the non-linear medium of digital space.
4.     Information literacy is the ability to search, locate, assess and critically evaluate information found on the web and on-shelf in libraries.
5.   Socio-emotional literacy refers to the social and emotional aspects of being present online, whether it may be through socializing, and collaborating, or simply consuming content.
Use in education
  Source: edc.org
Schools are continuously updating their curriculum for digital literacy to keep up with accelerating technological developments. This often includes computers in the classroom, the use of educational software to teach curriculum, and course materials being made available to students online. Some classrooms are designed to use smartboards andaudience response systems. These techniques are most effective when the teacher is digitally literate as well.
Teachers often teach digital literacy skills to students who use computers for research. Such skills include verifying credible sources online and how-to cite web sites. Google and Wikipedia are used by students "for everyday life research.
Educators are often required to be certified in digital literacy to teach certain software and, more prevalently, to prevent plagiarism amongst students.
Digital natives and immigrants
Source: hnoblogs
Marc Prensky invented and popularized the terms "digital native" and "digital immigrant." A digital native, according to Prensky, is one who was born into the digital age. A digital immigrant refers to one who adopts technology later in life. These terms aid in understanding the issues of teaching digital literacy, however, simply being a digital native does not make one digitally literate.
Digital immigrants, although they adapt to the same technology as natives, possess a sort of "accent" which restricts them from communicating the way natives do. In fact, research shows that, due to the brain's malleable nature, technology has changed the way today's students read, perceive, and process information. This means that today's educators may struggle to find effective teaching methods for digital natives. Digital immigrants might resist teaching digital literacy because they themselves weren't taught that way. Prensky believes this is a problem because today's students are "a population that speaks an entirely new language" than the people who educate them.
Statistics and popular representations of the elderly and digital technologies portray them as digital immigrants. For example, in 2010 in Canada, 29% of those 75+ and 60% of those 65-74 had browsed the Internet in the past month whereas this activity almost reached 100% among those 15-24 years old. Eugene Loos identifies the most common assumptions about digital technologies and the elderly, all of which contribute to portray them as digital immigrants and to perpetuate digital ageism: senior citizens may be regarded as a homogenous group; this group does not want to or is not able to make use of digital information sources; however, it is not perceived as a problem, because as time passes, these generations will be succeeded by new generations that have no problem at all with digital technologies. The heterogeneity of cohorts, interest in technologies changing according to life events, and the importance of regular use to develop skills and literacy are examples of other elements to take into account.
Digital visitors and residents
In contrast to Marc Prensky, Dave White from the Department for Continuing Education at the University of Oxford has been publicising his concept of digital visitors and residents. Briefly, the concept is that visitors leave no online social trace whereas residents live a portion of their lives online. These are not two separate categories of people but rather a description of a continuum of behaviours. It is probable that many individuals demonstrate both visitor and residential behaviours in different contexts. Dave White has developed a mapping tool which explores this concept.
Digital writing

Source: textboss
Digital writing is a new type of composition being taught increasingly within universities. Digital writing is a pedagogy focused on technology's impact on writing environments; it is not simply using a computer to write. Rather than the traditional print perspective, digital writing enables students to explore modern technologies and learn how different writing spaces affect the meaning, audience, and readability of text. Educators in favor of digital writing argue that it is necessary because "technology fundamentally changes how writing is produced, delivered, and received." The goal of teaching digital writing is that students will increase their ability to produce a relevant, high-quality product, instead of just a standard academic paper.
One aspect of digital writing is the use of hypertext. As opposed to printed text, hypertext invites readers to explore information in a non-linear fashion. Hypertext consists of traditional text and hyperlinks that send readers to other texts. These links may refer to related terms or concepts like wikipedia or they may enable readers to choose the order in which they read. The process of digital writing requires the composer to make unique "decisions regarding linking and omission." These decisions "give rise to questions about the author's responsibilities to the text and to objectivity."
Use in society

Source: jpaap.napier.ac.uk
Digital literacy helps people communicate and keep up with societal trends. Literacy in social network services and Web 2.0sites helps people stay in contact with others, pass timely information and even sell goods and services. This is mostly popular among younger generations, though sites like LinkedIn have made it valuable to older professionals.
Digital literacy can also prevent people from believing hoaxes that are spread online or are the result of photo manipulation.E-mail frauds and phishing often take advantage of the digitally illiterate, costing victim’s money and making them vulnerable to identity theft.
Research has demonstrated that the differences in the level of digital literacy depend mainly on age and education level, while the influence of gender is decreasing (Hargittai, 2002; van Dijk, 2005; van Dijk and van Deursen, 2009). Among young people, in particular, digital literacy is high in its operational dimension (e.g. rapidly move through hypertext, familiarity with different kinds of online resources) while the skills to critically evaluate content found online show a deficit (Gui and Argentin, 2011).
Building on digital literacy is the concept of digital creativity which is the expression of creative skills in the digital medium. This can include programming, web sites and the generation and manipulation of digital images.
Social networking
With the emergence of social networking, one who is digitally literate now has a major voice online. The level of digital literacy needed to voice an opinion online today compared to the Internet before social networks is minute. Websites like Facebook and Twitter, as well as personal websites and blogs have enabled a new type of journalism that is subjective, personal, and "represents a global conversation that is connected through its community of readers."  These online communities foster group interactivity among the digitally literate. Social networks also help users establish a digital identity, or a "symbolic digital representation of identity attributes." Without digital literacy or the assistance of someone who is digitally literate, one cannot possess a personal digital identity. This is closely allied to Web Literacy.
Digital divide
Digital literacy and digital access have become increasingly important competitive differentiators.  Bridging the economic and developmental divides is in large measure a matter of increasing digital literacy and access for peoples who have been left out of the information and communications technology revolutions.
Scholar Howard Besser contends that the digital divide is more than just a gap between those who have access to technology and those who don’t. This issue encompasses aspects such as information literacy, appropriateness of content, and access to content. Beyond access, a digital divide exists between those who apply critical thinking to technology or not, those who speak English or not, and those who create digital content or merely consume it.
Research published in 2012 found that the digital divide, as defined by access to information technology, does not exist amongst youth in the United States. Young people of all races and ethnicities report being connected to the internet at rates of 94-98%. There remains, however, a Civic Opportunity Gap, where youth from poorer families and those attending lower socioeconomic status schools are less likely to encounter opportunities to apply their digital literacies toward civic ends.
Community Informatics overlaps to a considerable degree with digital literacy by being concerned with ensuring the opportunity not only for ICT access at the community level but also, according to Michael Gurstein, that the means for the "effective use" of ICTs for community betterment and empowerment are available.  Digital literacy is of course, one of the significant elements in this process.
The United Nations Global Alliance for ICT and Development (GAID). seeks to address this set of issues at an international and global level. Many organizations (e.g. Per Scholas for underserved communities in the United States andInterConnection for underserved communities around the world as well as the U.S.) focus on addressing this concern at national, local and community levels.
Digital Citizen

       Source: tidesinc.org
A digital citizen refers to a person utilizing information technology (IT) in order to engage in society, politics, and government participation. K. Mossberger, et al. define digital citizens as "those who use the Internet regularly and effectively". Digital citizenship can be defined as the norms of appropriate, responsible behaviour with regard to technology use. 
·         Digital access: full electronic participation in society.
·         Digital commerce: electronic buying and selling of goods.
·         Digital communication: electronic exchange of information.
·         Digital literacy: process of teaching and learning about technology and the use of technology.
·         Digital etiquette: electronic standards of conduct or procedure.
·         Digital law: electronic responsibility for actions and deeds.
·         Digital rights and responsibilities: those freedoms extended to everyone in a digital world.
·         Digital health and wellness: physical and psychological well-being in a digital technology world.
·         Digital security (self-protection): electronic precautions to guarantee safety.
Global impact

Government officials around the world have emphasized the importance of digital literacy for their economy. According to HotChalk, an Online resource for educators: "Nations with centralized education systems, such as China, are leading the charge and implementing digital literacy training programs faster than anyone else. For those countries, the news is good."
Code.org was started in 2013 to expand access to computer science, and increasing participation by women and underrepresented students of colour.
Many developing nations are also focusing on digital literacy education to compete globally.
Economically, socially and regionally marginalised people have benefited from the ECDL Foundation’s ECDL programme through funding and support from Corporate Social Responsibility initiatives, international development agency funding and non-governmental organisations(NGO’s).
Ministry of science and technology Nepal gov’t has set a various plans and policies to provide ICT competencies and literacy as well, though it’s departments and ministry of education also promoting to design various courses to figure global standard.
The PhilippinesEducation Secretary Jesli Lapus has emphasized the importance of digital literacy in Filipino education. He claims a resistance to change is the main obstacle to improving the nation's education in the globalized world. In 2008, Lapus was inducted into Certiport's "Champions of Digital Literacy" Hall of Fame for his work to emphasize digital literacy.
Use in the workforce

Source: slideshare.net
Those who are digitally literate are more likely to be economically secure. Many jobs require a working knowledge of computers and the Internet to perform basic functions. As wireless technology improves, more jobs require proficiency with cell phones and PDAs (sometimes combined into smart phones).
White collar jobs are increasingly performed primarily on computers and portable devices. Many of these jobs require proof of digital literacy to be hired or promoted. Sometimes companies will administer their own tests to employees, or official certification will be required.
As technology has become cheaper and more readily available, more blue-collar jobs have required digital literacy as well. Manufacturers and retailers, for example, are expected to collect and analyse data about productivity and market trends to stay competitive. Construction workers often use computers to increase employee safety.
Job recruiters often use employment Web sites to find potential employees, thus magnifying the importance of digital literacy in securing a job.
The 2014 Workforce Innovation and Opportunity Act (WIOA)...defines digital literacy skills as a workforce preparation activity.
