There are many Electronic products, gadgets available for us to use in our daily life which are become mandatory for us. Let me touch those things here.
Mobile phones: Eariler days we used to have a land phone to make a call to others and to receive calls from others. That times the uses were limited. But now a days the evolution of the mobile phones made the landlines to disappear from the scene. Mobile phones not only useful to call or receive call but also can send messages, play music, play games, and more over now a days we can evern browse web pages, check e-mails. Mobile phones are become common thing for all. Even small childrens are using them. In Japan one school ordered there students to come to the school with that Iphone, according to them they use some technology which recognises the phone id and gives attendance to the student. This one example shows how the technology is binding humans with it.
PDA: It means Personal Digital Assistance. We can say it as a Handheld computer or a Palmtop. It is like having a small computer in hand. With this PDA we can Store the data using memory cards, and can connect to internet, intranet, via Wi-Fi. According to the sources it was first introduced in 1983. But the Term PDA was named to it by Joh Schulley of Apple Computer in 1992 in a consumer Electronics show in Los Vegas. After some years of works and modifications the complete use was started in 1995 and then it dint look back and Most of the IT persons in the world having this PDA with them now. Though you have a laptop with you, you can use this to get Internet connection. Now a days Mobiles are replacing the PDA's as they can be useful for calls also they can be useful for connecting to the net.
