In configuration management, a baseline is an agreed description of the attributes of a product, at a point in time, which serves as a basis for defining change. [ 1] A change is a movement from this baseline state to a next state. The identification of significant changes from the baseline state is the central purpose of baseline identification.
Configuration management ( CM) is a management process for establishing and maintaining consistency of a product's performance, functional, and physical attributes with its requirements, design, and operational information throughout its life. [ 1][ 2] The CM process is widely used by military engineering organizations to manage changes ...
Many computers, especially older models, have user accessible "reset" buttons that assert the reset line to facilitate a system reboot in a way that cannot be trapped (i.e. prevented) by the operating system. Out-of-band management also frequently provides the possibility to reset the remote system in this way.
In effect, this is a multistage watchdog timer in which the software comprises the first and intermediate timer stages and the hardware reset the final stage. In a Linux system, for example, the watchdog daemon could attempt to perform a software-initiated restart, which can be preferable to a hardware reset as the file systems will be safely ...
v. t. e. An operating system ( OS) is system software that manages computer hardware and software resources, and provides common services for computer programs . Time-sharing operating systems schedule tasks for efficient use of the system and may also include accounting software for cost allocation of processor time, mass storage, peripherals ...
FLAGS register. The FLAGS register is the status register that contains the current state of an x86 CPU. The size and meanings of the flag bits are architecture dependent. It usually reflects the result of arithmetic operations as well as information about restrictions placed on the CPU operation at the current time.
Reboot to restore software. Reboot to restore software is a system of restore technology that enables restoring the user-defined system configuration of a computing device after every restart. [1] The technology maintains systems in their optimal working conditions and is used in multi-user computing environments. [2]
A control store is the part of a CPU's control unit that stores the CPU's microprogram.It is usually accessed by a microsequencer.A control store implementation whose contents are unalterable is known as a Read Only Memory (ROM) or Read Only Storage (ROS); one whose contents are alterable is known as a Writable Control Store (WCS).
