Reliability, availability and serviceability (RAS), also known as reliability, availability, and maintainability (RAM), is a computer hardware engineering term involving reliability engineering, high availability, and serviceability design. The phrase was originally used by IBM as a term to describe the robustness of their mainframe computers.
RAMP Simulation Software for Modelling Reliability, Availability and Maintainability (RAM) is a computer software application developed by WS Atkins specifically for the assessment of the reliability, availability, maintainability and productivity characteristics of complex systems that would otherwise prove too difficult, cost too much or take too long to study analytically.
In engineering, reliability, availability, maintainability and safety (RAMS) [1] [2] is used to characterize a product or system: . Reliability: Ability to perform a specific function and may be given as design reliability or operational reliability
A reliability block diagram (RBD) is a diagrammatic method for showing how component reliability contributes to the success or failure of a redundant system. RBD is also known as a dependence diagram (DD).
Memory management (also dynamic memory management, dynamic storage allocation, or dynamic memory allocation) is a form of resource management applied to computer memory.The essential requirement of memory management is to provide ways to dynamically allocate portions of memory to programs at their request, and free it for reuse when no longer needed.
Subsequently, several memory forensics tools were developed intended for practical use. These include both commercial tools like Responder PRO, Memoryze, winen, Belkasoft Live RAM Capturer, etc.. New features have been added, such as analysis of Linux and Mac OS X memory dumps, and substantial academic research has been carried out. [5] [6]
Core dumps allow a user to save a crash for later or off-site analysis, or comparison with other crashes. For embedded computers , it may be impractical to support debugging on the computer itself, so analysis of a dump may take place on a different computer.
Dynamic random-access memory (dynamic RAM or DRAM) is a type of random-access semiconductor memory that stores each bit of data in a memory cell, usually consisting of a tiny capacitor and a transistor, both typically based on metal–oxide–semiconductor (MOS) technology. While most DRAM memory cell designs use a capacitor and transistor ...
