IPhone 4S: New Technology

It is like a passion of this new generations’ to have iPhone. Apple introduced iPhone in 2007 for first time. And it became most successful technology and the evidence of this is a line of thousands of customers to be the first to buy the phones, which featured computing and Wi-Fi capabilities, along with a crisp, computer-like display on an innovative touch screen.

It constantly and continuously improves it and make new version with special features. Following this principle in October 2011, the company revealed an excitedly awaited new version of the device, the iPhone 4S.  It is the fifth generation of the iPhone and retains the exterior design of its predecessor, the iPhone 4, but is host to a range of improved hardware specifications and software updates.

Some of the special feature make it more special and more demanded, the phone added a voice recognition system known as Siri, that recognized voice commands by users to schedule appointments, dictate text messages and conduct Web searches; and a cloud storage service named iCloud which is the easiest way to manage all your stuff, because it manages it all for you. iCloud stores your music, photos, apps, mail, contacts, calendars, documents, and more. And wirelessly pushes them to all your devices. It’s automatic, effortless, and seamless. The iSight camera just might be the best camera ever on a phone. And with all-new optics, it just might be the only camera you need. Because behind every shot, you’ve got 8-megapixel resolution and a custom lens with a larger f/2.4 aperture

Although the new phone was virtually indistinguishable on the outside from its predecessor, the iPhone 4, it was packed with better technical innards, including a more advanced camera. The phone also included a more powerful chip known as the A5, the same microprocessor that acts as the brains inside the iPad.

Student and Technology

One side we promote students to use technology, and in other side we are afraid with the situation of the student who spends their time in computer or technology. We can see students of college and schools are continuously hanging with computer, Internet and other technological stuff. We heard complain about students are using more technology than ever, they love to spend there time in technology. More clearly students love to spend their time in social media like facebook, twitter and google+. The question is “Is this right?”. Answer is simple “effective technology use in education is right and should promote.”. So it is necessity for an investigation into how students use information technology in college and school and how it can be harness to improve the learning experience.

Here is a simple saying "ICT is not a good substitute for good teaching. Good teachers are good with or without ICT and students learn a great deal from them. Poor teachers are poor with or without ICT and students learn little from them." Then how can we consider the affection of ICT in learning, most of the research and polling shows that majority percentage of students said IT help them for research specially google and Wikipedia.

Usage of social media by student is not just limited with status writing and chatting, Collaboration learning and group studies are practiced by them. We often got this example in different groups in social media. Another great study and resulting infographic from mastersineducation.org showcases that social media and education not only can coexist, but students excel by using social media as a collaboration and education tool.

Communication over the internet plays such a huge role in students' lives today and sadly if they aren't able to understand what can happen the consequences can be horrific. Students really need to understand their rights on the internet.I heard that a talented school girl, only 15, who had qualified to play in a state sports team in USA took her life as a result of being cyber bullied. Last year one friend of a girl abuse her by using her fake facebook account. last year one boy(school level student) killed in india by kidnapper, because the boy used to show him billionaire in facebook.

It is always more complex than it seems but at least if students were made aware of their rights on the internet as well as what to do in situations like that one, then perhaps we would see the rate of tragedies like this occurring decrease.

Better understanding the purpose and knowledge of right will lead the student in right way. Student can extend their knowledge, they are not limited with just a single book and teacher, they get the change to move ahead through internet and find out the level.

The interest of student in ICT education is not just interest in technology; there is a scope behind it. The scope of ICT is boundless, that means it is not just limited with some area, the scope is every where: the usage of ICT can be viewed independently or with other field (education, medial, finance, agriculture etc.). Student should use technology not just unknowingly, they should aware about what they are doing and their purpose for each time must clear.
