* A memory leak occurs when a program requests memory from the operating system and never returns the memory when it's done with it.

There is no need to allocate or deallocate memory explicitly and no chance of a memory leak.

Some other debugging tools have been designed to work with GDB, such as memory leak detectors.

In object-oriented programming, a memory leak happens when an object is stored in memory but cannot be accessed by the running code.

A memory leak has symptoms similar to a number of other problems ( see below ) and generally can only be diagnosed by a programmer with access to the program source code ; however, many people refer to any unwanted increase in memory usage as a memory leak, though this is not strictly accurate from a technical perspective.

A memory leak can diminish the performance of the computer by reducing the amount of available memory.

This means that a memory leak in a program that only runs for a short time may not be noticed and is rarely serious.

* Where the leak occurs within the operating system or memory manager.

The following example, written in pseudocode, is intended to show how a memory leak can come about, and its effects, without needing any programming knowledge.

The memory leak would occur if the floor number requested is the same floor that the lift is on ; the condition for releasing the memory would be skipped.

The memory leak lasts until the system is reset.

When power was turned on again, the program would restart and all the memory would be available again, but the slow process of memory leak would restart together with the program, eventually prejudicing the correct running of the system.

For this step the computer memory is separated into three regions: cells in the W-region are used for storage of the forms in the text-form list ; ;

offer two alternate methods to compute the skewness and kurtosis, each of which can save substantial computer memory requirements and CPU time in certain applications.

The Analytical Engine incorporated an arithmetic logic unit, control flow in the form of conditional branching and loops, and integrated memory, making it the first design for a general-purpose computer that could be described in modern terms as Turing-complete.

The Aster computer could use the software written for the popular Tandy TRS-80 computer while fixing many of the problems of that computer, but it could also run CP / M software, with a big amount of free memory ( Transient Program Area, TPA ) and a full 80 × 25 display, and it could be used as a Videotext terminal.

Tradition ( e. g. Donald Knuth's ( 1973 ) hypothetical MIX computer ), for example, uses two instructions called load accumulator from register / memory ( e. g. " LDA r ") and store accumulator to register / memory ( e. g. " STA r ").

But during the 1960s faster and more affordable computers became available, and as prices decreased newer computer systems supported time-sharing, a system which allows multiple users or processes to use the CPU and memory.

By the mid 1960s, binary addressing had become the standard architecture in most computer designs, and main memory sizes were most commonly powers of two.

Early computer system documentation would specify the memory size with an exact number such as 4096, 8192, or 16384 words of storage.

But as computer main memory in a binary-addressed system is manufactured in sizes that were easily expressed as multiples of 1024, kilobyte, when applied to computer memory, came to be used to mean 1024 bytes instead of 1000.

while the HP 3000 business computer ( 1973 ) could have 64K, 96K, or 128K bytes of memory.

Unlike binary-addressed computer main memory, there is nothing in a disk drive that influences it to have a total capacity easily expressed using a power of 1024.

When a backplane is used with a plug-in single board computer ( SBC ) or system host board ( SHB ), the combination provides the same functionality as a motherboard, providing processing power, memory, I / O and slots for plug-in cards.

In computer security and programming, a buffer overflow, or buffer overrun, is an anomaly where a program, while writing data to a buffer, overruns the buffer's boundary and overwrites adjacent memory.

Significantly, the programs written for EDVAC were stored in high-speed computer memory rather than specified by the physical wiring of the computer.

The program is represented by a series of numbers that are kept in some kind of computer memory.

Many can be used on a standalone basis without a computer, using a memory card or USB connector.

Computer data storage, often called storage or memory, is a technology consisting of computer components and recording media used to retain digital data.

In computer science, garbage collection ( GC ) is a form of automatic memory management.

* Garbage collection ( computer science ), in automatic memory management

Other branches of cognitive science examine how human memory stores sounds, sights, smells, emotions, procedures, and abstract ideas.

* In computer science, lambda is the time window over which a process is observed for determining the working memory set for a digital computer's virtual memory management.

Michael Buckland, in an article published in 1992, suggested that the memex was severely flawed because Bush did not thoroughly understand information science and had a bad opinion of indices and classification schemes: " Bush thought that the creation of arbitrary associations between individual records was the basis of memory, so he wanted ' mem ( ory -) ex ', or ' Memex instead of index '.

Examples of pathological science may include homeopathy, Martian canals, N-rays, polywater, water memory, and cold fusion.

In computer science, reference counting is a technique of storing the number of references, pointers, or handles to a resource such as an object, block of memory, disk space or other resource.

In computer science, sequential access means that a group of elements ( e. g. data in a memory array or a disk file or on magnetic tape data storage ) is accessed in a predetermined, ordered sequence.

In computer science, in the context of data storage and transmission, serialization is the process of converting a data structure or object state into a format that can be stored ( for example, in a file or memory buffer, or transmitted across a network connection link ) and " resurrected " later in the same or another computer environment.

* Climate science – In 2010, the German Climate Computing Centre ( DKRZ ) was generating 10, 000 TB of data per year, from a supercomputer with a 20 TB memory and 7, 000 TB disk space.

It depicts the six corporate acts of mercy — feeding the hungry, giving drink to the thirsty, clothing the naked, sheltering the homeless, visiting prisoners and the sick, and the inscription reads: " This window is sacred to the memory of Mary Anning of this parish, who died 9 March AD 1847 and is erected by the vicar and some members of the Geological Society of London in commemoration of her usefulness in furthering the science of geology, as also of her benevolence of heart and integrity of life.

* In science fiction, psychosurgery is typically presented as far more advanced than its modern day counterparts, often including such things as selective memory erasure, direct alteration of thoughts, and generally having a higher effectiveness than in reality.

In science, cognition is a group of mental processes that includes attention, memory, producing and understanding language, solving problems, and making decisions.

* Resource ( computer science ), physical or virtual entities of limited availability ( e. g., memory, processing capacity, and network speed ), including

* Reference ( computer science ), an object referring to data stored elsewhere in computer memory

In computer science, an object is a location in memory having a value and referenced by an identifier.

* The science and math wing of Cheney High School is dedicated to his memory.

Multiversion concurrency control ( MCC or MVCC ), in the database field of computer science, is a concurrency control method commonly used by database management systems to provide concurrent access to the database and in programming languages to implement transactional memory.

* Coalescence ( computer science ), the merging of adjacent blocks of memory to fill gaps caused by deallocated memory

In computer science, a reference is a value that enables a program to indirectly access a particular datum, such as a variable or a record, in the computer's memory or in some other storage device.
