Although, technology brings a new revolution in the world, but the question arises does every one has the facility to learn and take advantage from this technology? the answer is no because factors such as age, gender, race, income, education , and physical abilities can all impact one's access to technology and how one uses it.The term "digital divide" refers to the gap between those who have access to information and communications technology and those who do not- often referred to as the "haves" and "have nots" (Morely 274). A variety of wireless Internet projects that are designed to provide Internet access to rural schools and homes One Laptop Per Child (OLPC) is one of them. Nicolas Negroponte first announced his idea of a low cost laptop to be used by children at the World Economic Forum in Davos in 2005.The goal of OLPC is to ensure that every child in the world between the ages of 6 and 12 has immediate access to a personal laptop computer by 2015, in order to provide them with access to new channels of learning,sharing, and self expression (Morely 276). Three years ago, knight foundation set out to find ways to bridge the digital divide in Detroit , a formidable task in a city where less than 40 % of households have broadband access. The average rate for monthly internet access in Detroit is $30. Also, The Schools and Library Divisions (SLD) of the Universal Service Administrative Company(USAC) Enables schools, libraries, and rural health care providers that could not afford them, with networking wiring and access to both telecommunications and Internet services. so "E-rate" program require telecommunications companies to provide services to those who have the highest priority and discounts are given based on the household incomes of students family.Congress and the FCC approved 2.25 billion in annual funding. In the first year funding, the program helped connect 80,000 schools and 38 million children. ALCT (Alliance for Latino Community Technology) is dedicated to preparing Latino's to acquire the skills of technology literacy. So, we can say that these projects are trying to do their best to dissolve the difference of haves and have nots.
2. The EPA estimates that the e-waste generated by digital devices produces more than 2.5 million tons every year. Research and post "green" initiatives to promote sustainability and reduce the amount of e-waste.
Present time the life can't be imagine without technology, and we know all the work it doesn't matter it is a office work, or healthcare technology, education, paying bills, travel etc all the work have done through the computer technology. So, if the technology resources will be increase then definitely every one wants to buy it, and if every one want to take the advantage of this technology then after some time it will need repair or replacement . This is the reason why e-waste is increasing in present time, we also know the manufacturing of these devices and use of rare materials that go into their production represent a huge source of embodied energy. Minimizing e-waste helps to conserve resources and reduces the amount energy we take from the earth. If we think a little in depth then we can reduce the amount of e-waste.
-Try finding one device with multiple functions.
-Keep your device clean, and avoid overcharging the battery.
-Look for products labeled Energy star or certified by the Electronic Product Environment Assessment Tool (EPEAT).
-Donate used electronics to social programs and helps victims of domestic violence, children safety initiatives and more.
-Recycle electronics and batteries in e-waste recycling bins located around you.
I think, if every one take an initiative to save one device in a useful manner, then soon we can decrees the numbers of e-waste which will be support to green thought.
3. The textbook discusses assistive devices for PCs to help individuals with visual impairment. Research and post apps that google and other developers are creating to help visually impaired users use smartphones.
According to American Foundation for the Blind, about 10 million people in the United States are blind or partly blind. And some estimates predict that over the next 30 years, as the vast baby boomer generation ages, the number of adults with vision impairments could double. For the convenience of those people google and other developers develop new apps TalkBack and VoiceOver are two of them. TalkBack is a google-made application that adds spoken, audible and vibration feedback to a smart phone.Apple's assistive technology also include VoiceOver which is the world's first "gesture based screen reader" the company said and with this app the blind people interact with their devices using multitouch gestures on the screen. For example, if you slide a finger around the phone surface , the iPhone will read aloud the name of each application. In short, we can say that these advanced apps give a new touch to those people, who are unable to see the beauty of nature or unable to listen the voice of a bird when the sun rise.
