A fatal system error (also known as a system crash, stop error, kernel error, or bug check) occurs when an operating system halts because it has reached a condition where it can no longer operate safely (i.e., where critical data could be lost or the system damaged in other ways). In Microsoft Windows, a fatal system error can be deliberately caused from a kernel-mode driver with either the or function. However, this should only be done as a last option when a critical driver is corrupted and is impossible to recover. This design parallels that in OpenVMS. The Unix kernel panic concept is very similar. In Windows When a bug check is issued, a crash dump file will be created if the system is configured to create them. This file contains a "snapshot" of useful low-level information about the system that can be used to debug the root cause of the problem and possibly other things in the background. If the user has enabled it, the system will also write an entry to the syste ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Operating System
An operating system (OS) is system software that manages computer hardware and software resources, and provides common daemon (computing), services for computer programs. Time-sharing operating systems scheduler (computing), schedule tasks for efficient use of the system and may also include accounting software for cost allocation of Scheduling (computing), processor time, mass storage, peripherals, and other resources. For hardware functions such as input and output and memory allocation, the operating system acts as an intermediary between programs and the computer hardware, although the application code is usually executed directly by the hardware and frequently makes system calls to an OS function or is interrupted by it. Operating systems are found on many devices that contain a computerfrom cellular phones and video game consoles to web servers and supercomputers. , Android (operating system), Android is the most popular operating system with a 46% market share, followed ...

Microsoft Windows
Windows is a Product lining, product line of Proprietary software, proprietary graphical user interface, graphical operating systems developed and marketed by Microsoft. It is grouped into families and subfamilies that cater to particular sectors of the computing industry – Windows (unqualified) for a consumer or corporate workstation, Windows Server for a Server (computing), server and Windows IoT for an embedded system. Windows is sold as either a consumer retail product or licensed to Original equipment manufacturer, third-party hardware manufacturers who sell products Software bundles, bundled with Windows. The first version of Windows, Windows 1.0, was released on November 20, 1985, as a graphical operating system shell for MS-DOS in response to the growing interest in graphical user interfaces (GUIs). The name "Windows" is a reference to the windowing system in GUIs. The 1990 release of Windows 3.0 catapulted its market success and led to various other product families ...

Blue Screen Of Death
The blue screen of death (BSoD) or blue screen error, blue screen, fatal error, bugcheck, and officially known as a stop erroris a fatal system error, critical error screen displayed by the Microsoft Windows operating systems to indicate a crash (computing), system crash, in which the operating system reaches a critical condition where it can no longer operate safely. The name comes from the blue colored background used predominately on the error screens found in the majority of Windows releases. Possible issues contributing to a BSoD may include hardware failures, an issue with or without a device driver, computer virus, viruses, malware, and other factors such as intentional user action. __TOC__ History Blue screen errors have been around since the very first version of Windows in 1985. In the Beta Release of Windows 1.0, if it detected a version of DOS that is newer than the OS expects, the boot screen would have the text "Incorrect DOS version" alongside other messages ...

OpenVMS
OpenVMS, often referred to as just VMS, is a multi-user, multiprocessing and virtual memory-based operating system. It is designed to support time-sharing, batch processing, transaction processing and workstation applications. Customers using OpenVMS include banks and financial services, hospitals and healthcare, telecommunications operators, network information services, and industrial manufacturers. During the 1990s and 2000s, there were approximately half a million VMS systems in operation worldwide. It was first announced by Digital Equipment Corporation (DEC) as VAX/VMS (''Virtual Address eXtension/Virtual Memory System'') alongside the VAX-11/780 minicomputer in 1977. OpenVMS has subsequently been ported to run on DEC Alpha systems, the Itanium-based HPE Integrity Servers, and select x86-64 hardware and hypervisors. Since 2014, OpenVMS is developed and supported by VMS Software Inc. (VSI). OpenVMS offers high availability through computer cluster, clustering—the ability t ...

Unix
Unix (, ; trademarked as UNIX) is a family of multitasking, multi-user computer operating systems that derive from the original AT&T Unix, whose development started in 1969 at the Bell Labs research center by Ken Thompson, Dennis Ritchie, and others. Initially intended for use inside the Bell System, AT&T licensed Unix to outside parties in the late 1970s, leading to a variety of both academic and commercial Unix variants from vendors including University of California, Berkeley ( BSD), Microsoft (Xenix), Sun Microsystems ( SunOS/ Solaris), HP/ HPE ( HP-UX), and IBM ( AIX). The early versions of Unix—which are retrospectively referred to as " Research Unix"—ran on computers such as the PDP-11 and VAX; Unix was commonly used on minicomputers and mainframes from the 1970s onwards. It distinguished itself from its predecessors as the first portable operating system: almost the entire operating system is written in the C programming language (in 1973), which allows U ...

Kernel Panic
A kernel panic (sometimes abbreviated as KP) is a safety measure taken by an operating system's Kernel (operating system), kernel upon detecting an internal Fatal system error, fatal error in which either it is unable to safely recover or continuing to run the system would have a higher risk of major data loss. The term is largely specific to Unix and Unix-like systems. The equivalent on Microsoft Windows operating systems is a Blue screen of death, stop error, often called a "blue screen of death". The Kernel (operating system), kernel routines that handle panics, known as panic() in AT&T Corporation, AT&T-derived and Berkeley Software Distribution, BSD Unix source code, are generally designed to output an error message to the system console, console, dump an image of kernel memory to disk for post-mortem debugging, and then either wait for the system to be manually rebooted, or initiate an automatic reboot. The information provided is of a highly technical nature and aims t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kernel (operating System)
A kernel is a computer program at the core of a computer's operating system that always has complete control over everything in the system. The kernel is also responsible for preventing and mitigating conflicts between different processes. It is the portion of the operating system code that is always resident in memory and facilitates interactions between hardware and software components. A full kernel controls all hardware resources (e.g. I/O, memory, cryptography) via device drivers, arbitrates conflicts between processes concerning such resources, and optimizes the use of common resources, such as CPU, cache, file systems, and network sockets. On most systems, the kernel is one of the first programs loaded on startup (after the bootloader). It handles the rest of startup as well as memory, peripherals, and input/output (I/O) requests from software, translating them into data-processing instructions for the central processing unit. The critical code of the kernel is usua ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Windows Driver Kit
The Windows Driver Kit (WDK) is a software toolset from Microsoft that enables the development of device drivers for the Microsoft Windows platform. It includes documentation, samples, build environments, and tools for driver developers. A complete toolset for driver development also need the following: a compiler Visual Studio, Windows SDK, and Windows HLK. History Previously, the WDK was known as Device Development Kit (DDK) for Windows 3.x and Windows 9x. It supported the development of VxD drivers. Later versions for Windows NT and Windows 98SE and ME were called Driver Development Kit (DDK) and supported Windows Driver Model (WDM) development. It got its current name when Microsoft released Windows Vista Windows Vista is a major release of the Windows NT operating system developed by Microsoft. It was the direct successor to Windows XP, released five years earlier, which was then the longest time span between successive releases of Microsoft W ... and added the fo ...

WinDbg
WinDbg is a multipurpose debugger for the Microsoft Windows computer operating system, distributed by Microsoft. It can be used to debug user mode applications, device drivers, and the operating system itself in kernel mode. Overview Like the Visual Studio Debugger, WinDbg has a graphical user interface (GUI), but is more powerful and has little else in common. WinDbg can automatically load debugging symbol files (e.g., PDB files) from a server by using a unique ID embedded in the executable (using the "RSDS Guid") via SymSrv (SymSrv.dll), instead of requiring users to manually find the files. If a private symbol server is configured, the symbols can be correlated with the source code for the binary. This eases the burden of debugging problems that have various versions of binaries installed on the debugging target by eliminating the need for finding and installing specific symbols version on the debug host. Microsoft has a public symbol server that has most of the public sym ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
