WHAT IS ICT? According to Longman dictionary INFORMATION is : facts or details that tell you something about a situation, person, event etc COMMUNICATION is : the process by which people exchange information or express their thoughts and feelings TECHNOLOGY is : new machines, equipment, and ways of doing things that are based on modern knowledge about science and computersSo ICT is : machine, equipment or ways of giving orexchange fact or detail about a situation, person,event etc
WHY WE NEED ICT? Imagine yourself living in a jungle alone. No TV, telephone, electricity, internet, radio, satellite, friends to talk to just like the stone age period. How do you feel about it? Human being is a social creature, we must live and communicate each other. For that reason people invent many things to ease their social needs Nowadays, people hardly live without ICT. Its almost inn every sectors of our life. Kitchen,bedroom,office,school,mosque,church, even open spaces like park or street have available communication media. Internet,TV,Radio,Telephone,newspaper are unavailabe source to our life. Bussiness and pleasure runs smoothly with ICT
BRIEF HISTORY ABOUT ICT PremechanicalThe premechanical age is the earliest age ofinformation technology. It can be defined as thetime between 3000B. When humans first startedcommunicating they would try to use language orsimple picture drawings known as petrologlythswhich were usually carved in rock. Early alphabetswere developed such as the Phoenician alphabets.
ICT NOW AND THEN (COMPARISON) For people without disabilities, technology makes things easier. For people with disabilities, technology makes things possible. Take, for example, the 1980’s precursor to the Adaptech Research Network… I and a student with a visual impairment are working on a research paper. Our main technology is the typewriter. But… we heard of exciting innovations! Alas, a day and hundreds of windings and dollar signs (control characters) later we realize that word processing software for people who are blind is not yet ready for prime time. Back to the typewriter! But not for long. By the 1990s, a major challenge is price. But American legislation resulted in more and more general use ICTs incorporating access features. Primitive, yes, but definitely the beginning of universal design in this realm as people with different disabilities used mainstream ICTs as adaptive aids. For example, most people use spell checkers. For people with some learning disabilities this is adaptive technology that helps compensate for the disability. Dictation software, developed for professionals, was now used as adaptive technology by people with neuromuscular impairments. Screen reading and word prediction technologies, intended for individuals with disabilities, crossed over into the mainstream and were increasingly available on mobile devices. People with disabilities also used ICTs in idiosyncratic, creative ways, further clouding distinctions between general use and adaptive computer technologies.

BREAKTHROUGH ON ICT Advances that have transformed how the world communicates Advances that transformed how the world communicates are among the top twenty-five technological breakthroughs of the past quarter century, according to a panel of experts assembled by CNN, June 19, 2005. Advances in technology have done much to change the way we live and communicate over the past quarter century, but no breakthrough has revolutionized life as much as the advent of the "wireless world," according to a panel of experts assembled by CNN to pick the top 25. In 1980, many telephones were attached to walls, facts were found in books, and people had to browse shelves in a record store if they wanted to buy the latest music. Now, access to all of those and more is found by just reaching into our pocket. In the "Information Age" having immediate access to data is fundamental to progress. In some cases the advances are serving to overhaul industries at a lightning-fast pace.
BREAKTHROUGH ON ICT The internet allowed tech-savvy music lovers to force changes in the way the music industry does business. Text messaging over cell phones has made written communication more immediate. Having a computer in almost every American home (No. 5) has changed the way the world conducts business and how people communicate. Computers have gone from whirring behemoths to devices that fit in every room—or every pocket. Just as computer use is exploding worldwide, the brains behind them— the processors—are getting smaller. Computer chips made the list at No. 9, and today a chip that you can balance on your fingertip can hold massive amounts of data. This ability to store (No. 10) tons of information in cell phones or digital cameras allows us to keep our smart technology portable. Even as our technology is getting faster and smarter, so is the e- baggage (No. 20) that comes with it. When the internet age dawned, the World Wide Web seemed to be harmless. Today, however, we are mired in problems caused by things like online scams and viruses—traps aimed at taking down our computers and sometimes even our identities. An entire industry meant to curb e-baggage and protect consumers has formed in reaction to this threat.
BREAKTHROUGH ON ICTScripting our entertainment experience Technological advances have also transformed the entertainment industry. Satellite television and radio (No. 13) give consumers more choices. The development of the remote control (No. 21) allows viewers to tailor their own experiences. Video game technology has made great strides. In the early 1980s, the first wave of video games popularity was in full swing with a little yellow Pac Man gobbling dots on a computer screen. Today, the $10 billion a year industry produces realistic games that invite players into fantasy worlds, sports, and even wars. The hunger for bigger and better screens with which to watch the tailored programs or new video games is being met with technological improvements. Advancements made to our television and movie screens—such as plasma TV, HDTV and IMAX—made the list at No. 24.
BREAKTHROUGH ON ICTLeapfrogging into the future Many life-altering innovations in the past quarter-century were made in scientific laboratories. Researchers decoded the genetic makeup of many organisms (No. 7), which led to advances in biotechnology (No. 4)—the science of manipulating an organisms genetic material. DNA testing and forensic science (No. 14) made it possible to reunite an unidentified baby with his parents after the Asian tsunami. Law enforcement officers said it helped them crack the 30-year-old BTK serial killer case. Amazing new technologies are changing the way crimes are investigated and solved, although this science is still not as immediate as many prime-time crime television shows make it appear. Biometrics, the science of digitizing information; such as, fingerprints or facial features for accurate identification, and animal cloning join the ranks at Nos. 16 and 22, respectively.
BREAKTHROUGH ON ICTMaking advances Higher fuel prices sparked more interest in alternative fuel vehicles (No. 3), and so far hybrid vehicles curry the most favor with the growing number of consumers willing to pay more for their cars to save money on fuel. Hybrid vehicles are those that use at least two power sources, typically gasoline and electricity from batteries. As low-tech as it may seem, the compact fluorescent light bulb is doing a great deal to revolutionize quality of life. It is one of the most successful energy and water conservation devices developed to date; others include low-flow toilets and showerheads. Together they rank No. 17.

POSITIVE & NEGATIVE EFFECT OFICTPOSITIVE FASTER COMMUNICATION SPEED In the past, it took a long time for any news or messages to be send. Now with the Internet, news or messages are sent via e- mail to friends, business partners or to anyone efficiently. With the capability of bandwidth, broadband and connection speed on the Internet, any information can travel fast and at an instant. It saves time and is inexpensive. LOWER COMMUNICATION COST Using the Internet is cost-effective than the other modes of communication such as telephone, mailing or courier service. It allows people to have access to large amounts of data at a very low cost. With the Internet we do not have to pay for any basic services provided by the Internet. Furthermore, the cost of connection to the Internet is relatively cheap.
NEGATIVESOCIAL PROBLEMS THERE ARE SOME NEGATIVE EFFECTS OF ICT. ITHAS CREATED SOCIAL PROBLEMS IN THE SOCIETY. NOWADAYS,PEOPLE TEND TO CHOOSE ONLINE COMMUNICATION RATHER THANHAVING REAL TIME CONVERSATIONS. PEOPLE TEND TO BECOMEMORE INDIVIDUALISTIC AND INTROVERT. ANOTHER NEGATIVE EFFECT OF ICT IS :• FRAUD• IDENTITY THEFT• PORNOGRAPHY• HACKING THIS WILL RESULT A MORAL DECEDENT ANDGENERATE THREADS TO THE SOCIETY.HEALTY PROBLEMS A COMPUTER MAY HARM USERS IF THEY USE IT FORLONG HOURS FREQUENTLY. COMPUTER USERS ARE ALSO EXPOSEDTO BAD POSTURE, EYESTRAIN, PHYSICAL AND MENTAL STRESS. INORDER TO SOLVE THE HEALTH PROBLEMS, AN ERGONOMICENVIRONMENT CAN BE INTRODUCED. FOR EXAMPLE, AN ERGONOMICCHAIR CAN REDUCES BACK STRAIN AND A SCREEN FILTER IS USED TOMINIMIZE EYE STRAIN.
SUMMARY Information technology has entered our lives over a relatively brief period of time with little warning and essentially no formal educational preparation for most people. Many who currently use information technology have only a limited understanding of the tools they use and a (probably correct) belief that they are underutilizing them. Many citizens do not feel confident or in control when confronted by information technology, and they would like to be more certain of themselves. There have been impressive claims for the potential benefits of information technology, and many would like to realize those benefits. There is concern on the part of some citizens that changes implied by information technology embody potential risks to social values, freedoms or economic interests, etc., obligating them to become informed.Source :www.
