48656C6C6F

48656c6c6f is a hexadecimal representation of the ASCII string "Hello". It consists of five byte values: 0x48, 0x65, 0x6c, 0x6c, 0x6f. When interpreted as ASCII text, these bytes map to the characters H, e, l, l, o respectively. Hex notation expresses binary data using two hexadecimal digits for each byte, making it compact and readable for humans and machines.

In computing, hex strings like 48656c6c6f are commonly used to display or transmit binary data, perform debugging, and inspect memory or network payloads. They are not encryption or a cipher; they are a representation of raw bytes. The same approach applies to other characters and data, where each byte is shown as a two-digit hex value.

Decoding a hex string to text involves reversing the process: group the string into pairs of hex digits, convert each pair to its corresponding byte value, and interpret those bytes using a character encoding such as ASCII. For the specific string in question, decoding yields "Hello". If the data uses UTF-8 or another encoding for non-ASCII characters, multi-byte sequences may appear, but ASCII characters like H, e, l, l, o remain represented by the same hex values.

Case and variations: hex digits are commonly written in uppercase or lowercase, and prefixes like 0x may be used in code, but the underlying values are the same.
