The scope of test cases usually rely on the software tester involved, who uses experience and intuition to determine what situations commonly cause software failure, or may cause errors to appear. [2] Typical errors include divide by zero, null pointers, or invalid parameters. [3]
Error-correcting codes are used in lower-layer communication such as cellular network, high-speed fiber-optic communication and Wi-Fi, [11] [12] as well as for reliable storage in media such as flash memory, hard disk and RAM. [13] Error-correcting codes are usually distinguished between convolutional codes and block codes:

Common exceptions include an invalid argument (e.g. value is outside of the domain of a function), [5] an unavailable resource (like a missing file, [6] a network drive error, [7] or out-of-memory errors [8]), or that the routine has detected a normal condition that requires special handling, e.g., attention, end of file. [9]
The EDH packet also contains bits to signal that a prior link in a broadcast or transmission chain contained an error; equipment which receives a video signal with an incorrect CRC, and retransmits the signal, is expected to re-insert the correct CRC (which may be different if the equipment alters the video signal in any way) and set the flag ...

While performing this translation of technical errors into meaningful user messages, specific errors are often grouped into more generic errors, and this process can lead to user messages becoming so useless that the user doesn't know what went wrong or how to fix it.
No matter what the student puts for part a, the corresponding answer for part b can be calculated quickly. Lawson-Perfect discloses that this system cannot identify "why" a student made an error, but maintains that it is generally successful in providing fair ECF credit.
