An electronic dictionary means that the contents of a traditional dictionary are converted into files stored in a digital format and stored in memory. When users use it, they only need to input the items they need to query through the keyboard. The electronic dictionary

The earliest electronic dictionaries in China appeared around the end of the 1980s to the beginning of the 1990s.

Earlier, there were only very simple functions such as dictionaries and calculators. The keyboard and screen were designed together to make the display screen very small. Only simple translations were possible, and dictionary information could not be updated.

Subsequent mainstream designs typically have screens and keyboards separated, like a small laptop. With the advancement of technology, some are miniaturized, the size is as large as a credit card, and some are larger and clearer. The larger capacity is enough to build a large authorized dictionary, such as Oxford Advanced English-Chinese Dictionary Wait.

The electronic dictionary has been developed to have functions comparable to mobile phones and PDAs, and has a wide range of functions such as a color touch display, MP3 music playback, video playback, and Internet connection via WiFi. ^[1]
