Connectivity: 

Connectivity Connectivity to the PDA could be via wired i.e serial ports or other proprietary format, many today connect via USB cable. Most modern PDAs have Bluetooth wireless connectivity, Many mid-range and superior PDAs have Wi-Fi/WLAN/ 802.11 connectivity. 9

SYNCHRONIZATION: 

10 SYNCHRONIZATION PDAs are designed to complement your PC, they need to work with the same information in both places. An important function of PDAs is synchronizing data with a PC. The advantage of synchronization is that you always have a backup copy of your data, which can be a lifesaver if your PDA is broken, stolen.

Working of PDA’s: 

Working of PDA’s Micro processors . The Operating system . Batteries . LCD Display. Input Device .

Microprocessors : 

Microprocessors Like standard desktop and laptop computers, PDAs are powered by microprocessors. The microprocessor is the brain of the PDA and coordinates all of the PDA's functions according to programmed instructions. 21

The Operating System: 

The Operating System The operating system contains the pre-programmed instructions that tell the microprocessor what to do. There are many other operating systems, some designed solely for Smartphones. Example: Palm, Windows Mobile, iOS, Android. 22

Batteries: 

Batteries PDAs are powered by batteries. Some models use alkaline (AAA) batteries, while others use rechargeable batteries(lithium) The battery life depends on what kind of PDA one has and what it is used for. 23

LCD Display: 

LCD Display Unlike the LCD screens for desktop or laptop computers, which are used solely as output devices, PDAs use their screens for output and input. The LCD screens of PDAs are smaller than laptop screens, but vary in size. 24

Input Device: 

Input Device Palm-sized computers use a stylus and touch screen exclusively in combination with a handwriting recognition program . Eventually, most PDAs will incorporate voice recognition technology, where one speaks into a built-in microphone while software converts voice waves into data. 25
