Integer overflow
In computer programming, an integer overflow occurs when an arithmetic operation attempts to create a numeric value that is outside of the range that can be represented with a given number of digits – either higher than the maximum or lower t ...
, a condition that occurs when an integer calculation produces a result that is greater than what a given register can store or represent
*
Buffer overflow
In information security and programming, a buffer overflow, or buffer overrun, is an anomaly whereby a program, while writing data to a buffer, overruns the buffer's boundary and overwrites adjacent memory locations.
Buffers are areas of memory ...
, a situation whereby the incoming data size exceeds that which can be accommodated by a buffer.
**
Heap overflow
A heap overflow, heap overrun, or heap smashing is a type of buffer overflow that occurs in the heap data area. Heap overflows are exploitable in a different manner to that of stack-based overflows. Memory on the heap is dynamically allocated at ...
, a type of buffer overflow that occurs in the heap data area

Overflow (software)
OVERFLOW - the OVERset grid FLOW solver - is a software package for simulating fluid flow around solid bodies using computational fluid dynamics (CFD). It is a compressible 3-D flow solver that solves the time-dependent, Reynolds-averaged, Nav ...
, a NASA-developed computational fluid dynamics program using overset (Chimera) grids
*
Overflow condition
Traffic shaping is a bandwidth management technique used on computer networks which delays some or all datagrams to bring them into compliance with a desired ''traffic profile''. Traffic shaping is used to optimize or guarantee performance, improv ...
, a situation that occurs when more information is being transmitted than the hardware can handle
*
Overspill
In nonstandard analysis, a branch of mathematics, overspill (referred to as ''overflow'' by Goldblatt (1998, p. 129)) is a widely used proof technique. It is based on the fact that the set of standard natural numbers N is not an internal su ...
, a proof technique in non-standard analysis, is less commonly called overflow
*
Stack overflow
In software, a stack overflow occurs if the call stack pointer exceeds the stack bound. The call stack may consist of a limited amount of address space, often determined at the start of the program. The size of the call stack depends on many fac ...
in which a computer program makes too many subroutine calls and its call stack runs out of space

River overflow
A flood is an overflow of water ( or rarely other fluids) that submerges land that is usually dry. In the sense of "flowing water", the word may also be applied to the inflow of the tide. Floods are an area of study of the discipline hydrolog ...
, a relatively long and significant increase in the water content of a river, causing a rise in its level
*
Sanitary sewer overflow
Sanitary sewer overflow (SSO) is a condition in which untreated sewage is discharged from a sanitary sewer into the environment prior to reaching sewage treatment facilities. When caused by rainfall it is also known as wet weather overflow. Cause ...
, a condition whereby untreated sewage is discharged into the environment, escaping wastewater treatment
