Circuit breaker design pattern. Circuit breaker is a design pattern used in software development. It is used to detect failures and encapsulates the logic of preventing a failure from constantly recurring, during maintenance, temporary external system failure or unexpected system difficulties. Circuit breaker pattern prevents cascading failures ...
There exist different mechanisms for software fault tolerance, among which: Recovery blocks; N-version software; Self-checking software; Operating system failure. Computer applications make a call using the application programming interface (API) to access shared resources, like the keyboard, mouse, screen, disk drive, network, and printer ...
Systems programming, or system programming, is the activity of programming [1] computer system software. The primary distinguishing characteristic of systems programming when compared to application programming is that application programming aims to produce software which provides services to the user directly (e.g. word processor ), whereas ...
Software rot ( bit rot, code rot, software erosion, software decay, or software entropy) is the deterioration of software quality or performance over time that leads to it becoming faulty, unusable, or needing upgrade . Since software cannot physically decay, the term is hyperbole. The process is due to either changes in the source code or to ...
In software development, a breakpoint is an intentional stopping or pausing place in a program, put in place for debugging purposes. It is also sometimes simply referred to as a pause . More generally, a breakpoint is a means of acquiring knowledge about a program during its execution. During the interruption, the programmer inspects the test ...
Native (computing) In computing, native software or data-formats are those that were designed to run on a particular operating system. In a more technical sense, native code is code written specifically for a certain processor. [1] In contrast, cross-platform software can be run on multiple operating systems and/or computer architectures .
Semaphore (programming) In computer science, a semaphore is a variable or abstract data type used to control access to a common resource by multiple threads and avoid critical section problems in a concurrent system such as a multitasking operating system. Semaphores are a type of synchronization primitive.
Interrupt handler. In computer systems programming, an interrupt handler, also known as an interrupt service routine or ISR, is a special block of code associated with a specific interrupt condition. Interrupt handlers are initiated by hardware interrupts, software interrupt instructions, or software exceptions, and are used for implementing ...
