Personal Digital Assistant or PDA, is also known as 'palmtop' and sometimes 'Smart Phones'. It is a portable electronic and communication device which can be integrated with education tools like interactive whiteboards, visualizers, voting systems etc (provided the compatibility exist) to enhance personalized learning and teaching environment, to provide a collaborative learning experience and to boost mobile learning. Teachers and students can use this device like an hand held portable computer for calculations, internet browsing, sending and receiving e-mails, e learning, e tutoring, word processing, numerical data processing (spreadsheets), database management (like address books), intranet/extranet access, digital note taking, blogs, pod casts, wikis etc. Many PDAs have video recording, sound recording, bluetooth, wifi and colored touch screen display which make them ideal for recording and sharing lectures, e learning material, proceedings of an experiment, seminar, conference, debate etc.
Just like interactive whiteboards, PDAs also come with stylus, which is used to handle its functions by tapping its touch screen to activate virtual buttons. The technology which is generally used for network connectivity is Bluetooth, wifi or IrDA. New PDAs have the ability to receive signals from radio stations and hence they can also be used to hear news and latest development in education, science, politics, business, economics and technology. Through GPS (Global Positioning System) enabled PDAs, one can calculate his absolute geographic position anywhere on earth. These devices also act as a mobile phone when used for making and receiving calls. All these features make them a boon especially for the geology, geography and archeology students who go outdoors for surveying, navigation, tracking and camping.
