All about System, device and HTTP error/status codes

Something that we all are aware of but know little about.

System Error Code: (Definition) a system error code is an error number, sometimes followed by a short error message that a program in Windows may display in response to a particular issue it's having.

System error codes are provided to software programmers as part of the programming interface with the Windows operating system. In other words, system error codes are predefined error codes and error messages that software programmers can use with their software to tell you (the software user) that the program is experiencing a particular problem.

Not every software program uses these predefined system error codes. Some software programs have their own sets of error numbers and error messages.

Device Manager Error Code : (Definition) Device Manager error codes are numerical codes, accompanied by an error message, that help you determine what kind of issue Windows is having with a piece of hardware. Device Manager Error codes only display in Device Manager.

HTTP Status Code: (Definition) HTTP status codes are standard response codes given by web site servers on the Internet. The codes help identify the cause of the problem when a web page or other resource does not load properly.

The term HTTP status code is actually the common term for the HTTP status line that includes both the HTTP status code and the HTTP reason phrase.

For example, the HTTP status line 500: Internal Server Error is made up of the HTTP status code of 500 and the HTTP reason phrase of Internal Server Error.
