Final answer:
The function/keyword pair ENCODE_FOR_URI() is used to encode specific characters in a URI component into a percent-encoded format, ensuring that the data conforms to web standards and can be transmitted over the Internet.
Step-by-step explanation:
What is the function/keyword pair ENCODE_FOR_URI()?
The function/keyword pair ENCODE_FOR_URI() is a function in various programming languages and technologies used for encoding a Uniform Resource Identifier (URI). Its main purpose is to convert certain characters within a string that are not allowed in a URI into their respective percent-encoded representation. This is crucial when creating URI query parts to ensure that they conform to the standards of the Web and can be transmitted over the Internet without error.
For example, when encoding a URI component, a space character would typically be encoded as '%20', which is its ASCII value in hexadecimal preceded by a percent symbol. This allows for the transmission of data that would otherwise conflict with URI delimiters or have special meanings in URIs. Similar encoding transformations would apply for other non-allowed characters.
