The full form of PDA is Personal Digital Assistant. PDAs are portable computers without keyboards with screens for writing or drawing on styluses resembling pens. They can link, upload, read charts, take notes, and access the internet. PDAs are sometimes known as palmtops or pocket computers.
PDAs come with either a stylus or a keyboard. Many PDAs were initially pen-based, utilising a stylus as opposed to a keyboard for input. Voice recognition technology is also used by many PDAs to process voice inputs.
