Hand-held
Encyclopedia
Handheld electronics is a common name for light mobile devices. Handheld electronics includes personal digital assistant
s (PDAs), such as Palm Pilots or cellular telephones with connectivity to a network such as the internet. Due to limited size of this machines developers of this system and applications face many challenges. For example, a PDA is typically about 5 inches (12.7 cm) in height and 3 inches (7.6 cm) in width and it weight less than 0.5 pounds (226.8 g).
Due to this limited size, most handheld devices have a small amount of memory, include slow processors
, and feature small displays (generally touchscreen
s, in order to save the space and weight of the keyboard) and weight not more than 2 pound (0.90718474 kg).
