INFORMATION TECHNOLOGY

INTRODUCTION

Technology is the knowledge of tools, techniques, systems to solve a problem or serve some purpose.

The word technology comes from Greek word technología;téchnē, meaning "art, skill, craft", and logia

meaning "study of-“ has affected society and its surroundings in a

number of ways. Information helps in the process of knowledge and

knowledge is regarded as power. Technology makes information gathering fast and

easy. Created a new branch called Information

Technology (IT). It involves the processing of information by a

computer.

INFORMATION

Data that has been processed into a form that is meaningful to the recipient and is of real value in current of future actions.

INFORMATION TECHNOLOGY (IT)

It is the acquisition, processing, storage and dissemination of vocal, pictorial, textual and numerical information by combination of computing and telecommunications.

PRESENT SCENARIO OF IT

The scenario of IT is described in the following four headings: Commoditisation and ConsumerisationTera-Architectures and VirtualisationNew Development and Acquisition and

Delivery ModelsCommunity and Collaboration

COMMODITISATION AND CONSUMERISATION

The impact of commoditisation and consumerisation of IT on enterprise technology and business as a whole will be far greater than anyone could have ever predicted due, in the main, to two factors: The commoditisation of the PC is enabling new

enterprise architecturesTechnology-enabled consumer power is

forcing businesses to become more agile and update their legacy systems

TERA-ARCHITECTURES AND VIRTUALISATION

Demand for infrastructure capacity will increase a hundredfold over the next ten years.

Virtualisation is breaking the direct link, which has existed for many years, between the physical devices and their usage

Virtualisation and tera-architectures support the model of the real-time enterprise (RTE)

NEW DEVELOPMENT AND ACQUISITION AND DELIVERY MODELS

The move in software development is towards open source which allows to meet the local demand.

COMMUNITY AND COLLABORATION

With commoditisation and consumerisation come not only revolutionary changes in enterprise IT but also life-altering changes to the way we interact with the wider world.

ROLE OF INFORMATION TECHNOLOGY

significant impact in research and development.

The major areas impacted by the advent of IT include library, business, media, education and so forth.

IT IN LIBRARY

A brief description of impact of ICTs on library and information services are listed below:

The implementation of ICT in the libraries has demanded new forms of library services to get more user satisfaction. Digital library service has evolved after the implementation of ICT in the library and information centers

Encourages participation and interaction by the user with the library in an Internet environment called web 2.0. An example of this could be a library setting up an RSS.

Offering podcast of library instruction (or audio-guided tours of the library) could be another example.

IT IN LIBRARY

Libraries have to acquire, organize, distribute and preserve information in digital formats

Library service have become web-based and information services electronic.

Strength of library is measured not on the basis of its collection but on the basis of its capacity in accessing and retrieving documents globally

IT IN MANAGEMENT

It is believed that IT has and will continue to revolutionize management. A few contributions of IT in management is given below: Creates new relationships between customers

and suppliers who electronically link themselves together.

Presents the opportunity for electronic commerce, which reduces purchasing cycle times, increases the exposure of suppliers to customers, and creates greater convenience for buyers.

Enables tremendous efficiencies in production and service industries through electronic data interchange to facilitate just-in-time production.

IT IN MANAGEMENT… Provides mechanisms through groupware for

coordinating work and creating a knowledge base of organizational intelligence.

Makes it possible for the organization to capture the knowledge of its employees and provide access to it through the organization

Provides the manager with electronic alternatives to face-to-face communications and supervision.

Provide developing countries with opportunities to compete with the industrialized nations

IT IN MEDIA

With the advent of information technology, two powerful forces have emerged to change the media.

The first is the use of computers used as a means of processing and analyzing information.

The second is the constantly accelerating capacity of the technology to enhance communication in areas such as entertainment and social awakening.

IT IN PRINT MEDIA

The print media is the most widespread of the media technology. It remains the widely adopted, portable, flexible and economical media. The most common example of print media is newspaper and book.

IT IN ELECTRONIC MEDIA

Despite the growing popularity of the Internet, radio and television still represent the mode through which people around the world receive information about national and international events.

Multimedia applications are increasingly been used as part of global revolution in electronic media.

IT IN EDUCATION

ICTs can be defined as a “diverse set of technological tools and resources used to communicate, and to create, disseminate, store, and manage information.”

ELECTRONIC LEARNING (E-LEARNING)

Although most commonly associated with higher education and corporate training, e-learning encompasses learning at all levels, both formal and non-formal, that uses an information network—theInternet, an intranet (LAN) or extranet (WAN)—w

BLENDED LEARNING

It is refers to learning models that combine traditional classroom practice with e-learning solutions. For example, students in a traditional class can be assigned both print-based and online materials, have online mentoring sessions with their teacher through chat, and are subscribed to a class email list.

A Web-based training course can be enhanced by periodic face-to-face instruction

OPEN AND DISTANCE LEARNING

“a way of providing learning opportunities that is characterized by the separation of teacher and learner in time or place, or both time and place; learning that is certified in some way by an institution or agency; the use of a variety of media, including print and electronic; two-way communications that allow learners and tutors to interact; the possibility of occasional face-to-face meetings; and a specialized division of labor in the production and delivery of courses.”

THE PROMISE OF ICTS IN EDUCATION

ICTs have the potential for increasing access to and improving the relevance and quality of education.

The new communications technologies promise to reduce that sense of isolation

HOW CAN ICTS HELP EXPAND ACCESS TO EDUCATION?
