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 ...
Software-defined networking ( SDN) is an approach to network management that enables dynamic and programmatically efficient network configuration to improve network performance and monitoring in a manner more akin to cloud computing than to traditional network management. [1] SDN is meant to improve the static architecture of traditional ...
IEEE 802.1aq is an amendment to the IEEE 802.1Q networking standard which adds support for Shortest Path Bridging ( SPB ). This technology is intended to simplify the creation and configuration of Ethernet networks while enabling multipath routing. [1] [2] [3]
A series of devices connected in a daisy chain layout. In electrical and electronic engineering, a daisy chain is a wiring scheme in which multiple devices are wired together in sequence or in a ring, [1] similar to a garland of daisy flowers. Daisy chains may be used for power, analog signals, digital data, or a combination thereof.
CAPTCHA. This CAPTCHA ( reCAPTCHA v1) of "smwm" obscures its message from computer interpretation by twisting the letters and adding a slight background color gradient. A CAPTCHA ( / ˈkæp.tʃə / KAP-chə) is a type of challenge–response test used in computing to determine whether the user is human in order to deter bot attacks and spam.
Electrical wiring is an electrical installation of cabling and associated devices such as switches, distribution boards, sockets, and light fittings in a structure. Wiring is subject to safety standards for design and installation. Allowable wire and cable types and sizes are specified according to the circuit operating voltage and electric ...
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 ...
Connection-oriented and connectionless communications. Very generally, most of communications can be divided into connection-oriented, and connectionless.Whether a communication is connection-oriented or connectionless, is defined by the communication protocol, and not by application programming interface (API).
