PDA stands for Personal Digital Assistant. It is a small phone fitted with several high tech facilities that enables you to perform the tasks that a CEO would normally employ an assistant to do; thus the name. The PDA is actually a combination of a phone and a computer.
There are several sizes of PDA. Some are about the size of a cigar box and others are as small as call cards. No matter what the size, the essence of the PDA has been the same - super functionality within limited space. A typical PDA would first function as a phone. You would be able to place calls, send messages, store numbers and set alarms. Then comes the slightly sophiscated functions: MP3 player, camera and appointment setter. Any PDA that performs functions above these primary ones may be called a fourth generation device. These include PDAs that can let you access the internet via WIFI and ones that incorporate GPS.
There are some PDAs that allow you to upgrade the existing software so you have enhanced functionality. For example, you can add more maps to the GPS so you can be able to find directions to more places. Some also have retractable mini keyboards that mimic the traditional PC layouts so you can type out your text quickly. The PDA was created to solve two main problems faced by business executives and people who need to work whilst on the road. First, there was the need to have a keyword layout similar to what we have on laptops but on a smaller scale. You would note that it would be very inconvenient to type ten paragraphs with the traditional toggle keypad of the phone. Secondly, the telecommuter needed to have all the functions performed by the assistant managed by the phone. So a PDA becomes an electronic device that is serving the user with both computer and office assistance wherever he goes. Some top PDA brands are Palm Z22 PDA, ASUS MyPal A639 PDA, Palm Tungsten E2 PDA and Palm LifeDrive Mobile.
