Since the 1950s, crash has been used attributively (before a noun) to denote something such as a course or programme that is done or undertaken urgently or quickly, e.g. a crash course in Russian or a crash diet. In this use, crash seems to be unaffected by possible associations of collision and violence (or indeed of computer failure), though a crash course in driving skills might come dangerously close to suggesting them.

Finance: precipitate drop in stock prices and economic activity, as in the crash of 1929, which initiated the Great Depression. Crashes are usually brought on by a loss in investor confidence.
Data processing: hardware failure or program error causing a computer to become inoperable. A well-designed operating system contains protection against inappropriate input so that a user’s program will not be able to cause a system crash.

1. n. A sudden, usually drastic failure. Most often said of the system (q.v., sense 1), esp. of magnetic disk drives (the term originally described what happens when the air gap of a hard disk collapses). “Three lusers lost their files in last night's disk crash.” A disk crash that involves the read/write heads dropping onto the surface of the disks and scraping off the oxide may also be referred to as a head crash, whereas the term system crash usually, though not always, implies that the operating system or other software was at fault.
2. v. To fail suddenly. “Has the system just crashed?” “Something crashed the OS!” See down. Also used transitively to indicate the cause of the crash (usually a person or a program, or both). “Those idiots playing SPACEWAR crashed the system.”
3. vi. Sometimes said of people hitting the sack after a long hacking run; see gronk out.

A crash (or system crash) in computing is a condition where a computer or a program, either an application or part of the operating system, ceases to function properly, often exiting after encountering errors. Often the offending program may appear to freeze or hang until a crash reporting service documents details of the crash. If the program is a critical part of the operating system kernel, the entire computer may crash. This is different from a hang or freeze where the application or OS continues to run without obvious response to input.
Many crashes are the result of the execution of a single machine instruction, but the causes of this are many fold. Typical causes are when the program counter is set to an incorrect address or a buffer overflow overwrites a portion of program code due to an earlier bug. In either case, it is quite common for the processor to attempt to execute data or random memory values. Since all data values are possible but only some values are valid instructions, this often results in an illegal instruction exception. By chance such data or random values could be valid (though unplanned) instructions. One might say that the original bug that upset the program counter "caused" the crash, but the actual fault was an illegal instruction some time later. The art of debugging such crashes is connecting the actual cause of the crash (easily determined) with the code that set off the chain of events. This is often very far from obvious—the original bug is usually perfectly valid code from the processor's perspective.
On earlier personal computers, it was actually possible to cause hardware damage through trying to write to hardware addresses outside of the system's main memory. Occasionally, execution of arbitrary data on a system will result in a breakup of screen display. This is widely considered a severe system crash.

Etymology
The term "crash" may originate from the phrase "head crash", which occurs when the read/write heads inside a hard disk physically come into contact with--"crash" into—the platter, the magnetic data storage surface of a hard disk. A head crash is catastrophic to the drive operation, roughly analogous to the severity of a computer crash to computer software.
Application crashes
An application typically crashes when it performs an operation which is not allowed by the operating system. The operating system then triggers an exception or signal in the application. Unix applications traditionally responded to the signal by dumping core. Most Windows and Unix GUI applications respond by displaying a dialog box (such as the one shown to the right) with the option to attach a debugger if one is installed. This behavior is called "crashing". Some applications attempt to recover from the error and continue execution instead of crashing.
Typical errors that result in application crashes include:
- attempting to read or write memory that is not allocated for reading or writing by that application (segmentation fault) or x86 specific (general protection fault)
- attempting to execute privileged or invalid instructions
- attempting to perform I/O operations on hardware devices to which it does not have permission to access
- passing invalid arguments to system calls
- attempting to access other system resources to which the application does not have permission to access (bus error)
- attempting to execute machine instructions with bad arguments (depending on CPU architecture): divide by zero, operations on denorms or NaN values, memory access to unaligned addresses, etc.
Website server crashes
The software running the server behind a website may crash, rendering it inaccessible entirely or providing only an error message instead of normal content.
For example: If a site was using a SQL database (such as MySQL) for a script (such as php) and that SQL server crashed, then php would display a connection error.
Operating system crashes
An operating system crash commonly occurs when a hardware exception occurs that cannot be handled. Operating system crashes can also occur when internal sanity-checking logic within the operating system detects that the operating system has lost its internal self-consistency.
Modern multi-tasking operating systems, such as Windows NT, Linux, or Mac OS X usually remain unharmed when an application program crashes.
