个人数字助理(Personal Digital Assistant),简称PDA,是可移动的、便携式电子产品。PDA的普通产品,即我们所称的电子记事本、电子辞典等。这种普通产品先天不足,首先是没有网络功能,其次是消费者的需要无法得到充分满足,再次是与其功能不相匹配的高价位。PDA的高端产品,即掌上电脑具有专为满足用户应用需求而开发的各种功能化产品,包括计算、字典、录音、图书、网络等功能,此类掌上电脑,实际上就是一台小电脑。它的优势具体表现在,CPU运行速度快(CPU速度已达400Mhz,相当于奔腾Ⅱ电脑),内存大(64M)、彩屏,主要应用于某一个行业领域,如医疗、公安等,显著提
Personal Digital Assistant (PDA) is a portable, portable electronic product. PDA’s common product, which we call the electronic notebook, electronic dictionary and so on. This common product is inherently deficient, first with no network function, secondly with the consumer’s inability to be fully satisfied, and again, the high price that does not match its function.

Such a PDA is actually a small computer. Its advantages are manifested in that the CPU runs at high speeds (CPU speed reaches 400Mhz, equivalent to Pentium II computer), large memory (64M) and color screen, which are mainly used in some industries such as medical care and public security,
