Which encoding uses the hex value of characters to transmit binary data, often used in data representations?

• A. Hex Encoding
• B. URL Encoding
• C. Base64 Encoding
• D. UTF-8 Encoding

Answer: (A)

Using the hex representation of bytes to convey binary data is hex encoding. In this approach, every byte of binary data is shown as two hexadecimal digits, ranging from 00 to FF, which makes the data readable in text form while preserving the exact byte values. This is why hex encoding is commonly used in data representations, memory dumps, and debugging tools—it provides a compact, unambiguous view of binary content. Other encodings serve different purposes: URL encoding escapes characters with a percent sign followed by hex values to safely include data in URLs; Base64 encoding converts binary data into a set of ASCII characters for efficient text transmission; UTF-8 encodes Unicode characters into bytes but does not represent arbitrary binary data as hex.
