ASCII

The American Standard Code for Information Interchange (ASCII) is an encoding standard that assigns numerical values to characters and translates them into computer-readable code. This translation enables machines to store, process, and efficiently share information.

Web developers and designers must ensure a web page displays text accurately and consistently, regardless of the device, screen size, or software. Following the ASCII standards allows them to prevent compatibility problems and create websites and apps with the correct text by defining precise character encoding for all textual data. 

For example, a developer building a site's contact form must define each form field's characters, such as name, age, sex, phone number, and email address. 

By using ASCII, developers can specify character limits and acceptable inputs, such as preventing users from entering letters in the age field.
