Until the past few years, we have gone to the technology, but with the new smaller and better machines, the technology is now going with us. The need for critical information at our fingertips is becoming even more important. Information is not useful unless we have timely access to it. Other developers are concentrating on making synchronizers to make the exchange of information between desktop computers, servers, and palmtops easier. Users are able not only to use the desktop computer to access information and practice information literacy but also to apply handheld computers for interacting with information that resides on desktop computers and the Internet.
Portability refers to the physical device.
Palmtops are small enough to be taken anywhere. They fit nicely into jacket pockets and purses or clip onto belts. Accessibility refers to the ability for users to get the information they need instantly. They no longer have to wait to get back to the office to check schedules or verify information. Mobility refers to the user who has the ability for greater movement and is not tethered to one place.
