This is a list of Hypertext Transfer Protocol (HTTP) response status codes. Status codes are issued by a server in response to a client's request made to the server. It includes codes from IETF Request for Comments (RFCs), other specifications, and some additional codes used in some common applications of the HTTP.
This is a list of Simple Mail Transfer Protocol (SMTP) response status codes. Status codes are issued by a server in response to a client's request made to the server. Unless otherwise stated, all status codes described here is part of the current SMTP standard, RFC 5321. The message phrases shown are typical, but any human-readable alternative ...
Common Winsock Error Codes (These are not FTP return codes) 10054: Connection reset by peer. The connection was forcibly closed by the remote host. 10060: Cannot connect to remote server. 10061: Cannot connect to remote server. The connection is actively refused by the server. 10065: No route to host / DNS cannot be resolved. 10066: Directory ...
These codes are grouped according to their first digit as "provisional", "success", "redirection", "client error", "server error" or "global failure" codes, corresponding to a first digit of 1–6; these are expressed as, for example, "1xx" for provisional responses with a code of 100–199.
The Integrated Database Management System ( IDMS) is a network model ( CODASYL) database management system for mainframes. It was first developed at B.F. Goodrich and later marketed by Cullinane Database Systems (renamed Cullinet in 1983). Since 1989 the product has been owned by Computer Associates (now CA Technologies), who renamed it ...
In computing, telecommunication, information theory, and coding theory, forward error correction ( FEC) or channel coding [1] [2] [3] is a technique used for controlling errors in data transmission over unreliable or noisy communication channels .
In computing, an error code (or a return code) is a numeric or alphanumeric code that indicates the nature of an error and, when possible, why it occurred. Error codes can be reported to end users of software, returned from communication protocols , or used within programs as a method of representing anomalous conditions.
In DOS there are only 256 error codes available, but DR DOS 6.0 and higher support 16-bit error codes at least in CONFIG.SYS. With 4DOS and DR-DOS COMMAND.COM, exit codes (in batchjobs) can be set by EXIT n and (in CONFIG.SYS) through ERROR=n. Exit statuses are often captured by batch programs through IF ERRORLEVEL commands.

An error-correcting code is a way of encoding x as a message such that Bob will successfully understand the value x as intended by Alice, even if the message Alice sends and the message Bob receives differ. In an error-correcting code with feedback, the channel is two-way: Bob can send feedback to Alice about the message he received.
