Hang (computing)In computing, a hang or freeze occurs when either a process or system ceases to respond to inputs. A typical example is when computer's graphical user interface (such as Microsoft Windows) no longer responds to the user typing on the keyboard or moving the mouse. The term covers a wide range of behaviors in both clients and servers, and is not limited to graphical user interface issues.
CompaqCompaq Computer Corporation est une entreprise d'informatique créée en 1982 par Rod Canion, Bill Murto et Jim Harris à Houston, Texas (États-Unis). Compaq est l'abréviation de COMPatibility And Quality. Compaq était un des principaux fabricants de compatibles PC durant les années 1980 et 1990. En mai 2002 Compaq est intégrée à la société Hewlett-Packard, après avoir souffert au cours de la seconde partie des années 1990 de la concurrence de Dell, dont l'investissement sur les serveurs a bénéficié de la bulle boursière internet et de la très forte hausse des sociétés de technologie.
Compaq PortableThe Compaq Portable is an early portable computer which was one of the first IBM PC compatible systems. It was Compaq Computer Corporation's first product, to be followed by others in the Compaq Portable series and later Compaq Deskpro series. It was not simply an 8088-CPU computer that ran a Microsoft DOS as a PC "work-alike", but contained a reverse-engineered BIOS, and a version of MS-DOS that was so similar to IBM's PC DOS that it ran nearly all its application software.
Monolithic kernelA monolithic kernel is an operating system architecture where the entire operating system is working in kernel space. The monolithic model differs from other operating system architectures (such as the microkernel architecture) in that it alone defines a high-level virtual interface over computer hardware. A set of primitives or system calls implement all operating system services such as process management, concurrency, and memory management. Device drivers can be added to the kernel as modules.
CopyIn computing, copy is a command in various operating systems. The command s from one directory to another. Generally, the command copies files from one location to another. It is used to make copies of existing files, but can also be used to combine (concatenate) multiple files into target files. The destination defaults to the current working directory. If multiple source files are indicated, the destination must be a directory, or an error will result.
OpenVMSOpenVMS (Open Virtual Memory System) anciennement VAX-11/VMS, VAX/VMS ou (officieusement) VMS est un système d'exploitation propriétaire créé par DEC en 1977 pour ses ordinateurs VAX. Le système a depuis été porté sur les processeurs DEC Alpha, et enfin Itanium. Hewlett-Packard Enterprise (HPE) détenait les droits sur OpenVMS jusqu'au , dont les dernières versions sont nommées OpenVMS, en raison de la présence d'une couche de compatibilité POSIX. C'est maintenant la société VMS Software, Inc.
ThunkIn computer programming, a thunk is a subroutine used to inject a calculation into another subroutine. Thunks are primarily used to delay a calculation until its result is needed, or to insert operations at the beginning or end of the other subroutine. They have many other applications in compiler code generation and modular programming. The term originated as a whimsical irregular form of the verb think. It refers to the original use of thunks in ALGOL 60 compilers, which required special analysis (thought) to determine what type of routine to generate.
Windows XP editionsWindows XP, which is the next version of Windows NT after Windows 2000 and the successor to the consumer-oriented Windows Me, has been released in several editions since its original release in 2001. Windows XP is available in many languages. In addition, add-ons translating the user interface are also available for certain languages. The first two editions released by Microsoft are Windows XP Home Edition, designed for home users, and Windows XP Professional, designed for business and power users.
