PDAs are very useful incross-country competitionsbe it road rally, bike rally, or trekking. It serves as the third eye as it helps tonavigate in unknown places and locations.
Many PDAs are used in car kits and are fitted with differential GlobalPositioning System (GPS) receivers to provide real time automobile navigation. PDAs are increasinglybeing fitted as standard on new cars. Many systems can also display traffic conditions and dynamic routing .
Like standard desktop and laptop computers, PDAs are powered by microprocessors. Themicroprocessor is the brainof the PDA and coordinates all of the PDAs functions according to programmed instructions.
The operating system is a program which act as an interface between the user and the hardware.
A PDA doesnt have a hard drive. It stores basic programs (address book, calendar, memo pad and operating system) in a read-only memory (ROM) chip, which remains intact even when the machine shutsdown. The data and any programs that are added later are stored in the devices RAM.
PDAs are powered by batteries. Some models usealkaline (AAA) batteries, while others use rechargeable batteries. The battery lifedepends on what kind of PDA one has and what it is used for.
Hand-held computers typically use a miniature keyboard in combination with a touchscreen. Palm-sized computersuse a stylus and touch screen exclusively in combinationwith a handwriting recognition program.

Computers are the guides to the Information Age. Over the years, they have assumed the role as administrators of data PDAs are the solution to this vision of ubiquitous computing These devices represent a new step in computer technology. PDAs are no different. But, eventually, they will fulfill their original purpose of being "all-knowing" and "all-doing" devices.
