Status Code
A three-digit numeric code in an HTTP response that indicates the outcome of a request. Status codes are grouped into five classes: 1xx (Informational), 2xx (Successful), 3xx (Redirection), 4xx (Client Error), and 5xx (Server Error). Other protocols like SIP, FTP, and SMTP use similar numeric code systems with their own semantics.
