Quiesce
To quiesce is to pause or alter a device or application to achieve a consistent state, usually in preparation for a backup or other maintenance. Description In software applications that modify information stored on disk, this generally involves flushing any outstanding writes; see buffering. With telecom applications, this generally involves allowing existing callers to finish their call but preventing new calls from initiating. Example Perhaps the best known support for this was incorporated into Microsoft Shadow Copies which was introduced in Microsoft Windows Server 2003. For an application to be quiesced during the shadow copy process, it must register itself as a writer and it is responsible for putting itself into a quiescent mode upon notification. Vendor schemes Various database and application vendors implement schemes to provide support for this feature including: * Symantec's Livestate – now includes a quiesce process, as does VMware's VI3 snapshot and VCB feat ...

Hard Disk
A hard disk drive (HDD), hard disk, hard drive, or fixed disk is an electro-mechanical data storage device that stores and retrieves digital data using magnetic storage with one or more rigid rapidly rotating platters coated with magnetic material. The platters are paired with magnetic heads, usually arranged on a moving actuator arm, which read and write data to the platter surfaces. Data is accessed in a random-access manner, meaning that individual blocks of data can be stored and retrieved in any order. HDDs are a type of non-volatile storage, retaining stored data when powered off. Modern HDDs are typically in the form of a small rectangular box. Introduced by IBM in 1956, HDDs were the dominant secondary storage device for general-purpose computers beginning in the early 1960s. HDDs maintained this position into the modern era of servers and personal computers, though personal computing devices produced in large volume, like cell phones and tablets, rely ...

Data Buffer
In computer science, a data buffer (or just buffer) is a region of a memory used to temporarily store data while it is being moved from one place to another. Typically, the data is stored in a buffer as it is retrieved from an input device (such as a microphone) or just before it is sent to an output device (such as speakers). However, a buffer may be used when moving data between processes within a computer. This is comparable to buffers in telecommunication. Buffers can be implemented in a fixed memory location in hardware—or by using a virtual data buffer in software, pointing at a location in the physical memory. In all cases, the data stored in a data buffer are stored on a physical storage medium. A majority of buffers are implemented in software, which typically use the faster RAM to store temporary data, due to the much faster access time compared with hard disk drives. Buffers are typically used when there is a difference between the rate at which data is received and t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shadow Copy
Shadow Copy (also known as Volume Snapshot Service, Volume Shadow Copy Service or VSS) is a technology included in Microsoft Windows that can create backup copies or snapshots of computer files or volumes, even when they are in use. It is implemented as a Windows service called the ''Volume Shadow Copy'' service. A software ''VSS provider'' service is also included as part of Windows to be used by Windows applications. Shadow Copy technology requires either the Windows NTFS or ReFS filesystems in order to create and store shadow copies. Shadow Copies can be created on local and external (removable or network) volumes by any Windows component that uses this technology, such as when creating a scheduled Windows Backup or automatic System Restore point. Overview VSS operates at the block level of volumes. A snapshot is a read-only point-in-time copy of the volume. Snapshots allow the creation of consistent backups of a volume, ensuring that the contents do not change and are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

JADE (programming Language)
JADE is a proprietary object-oriented software development and deployment platform product from the New Zealand-based Jade Software Corporation, first released in 1996. It consists of the JADE programming language, Integrated development environment and debugger, integrated application server and object database management system. Designed as an end-to-end development environment to allow systems to be coded in one language from the database server down to the clients, it also provides APIs for other languages, including .NET Framework, Java, C/C++ and Web services. Although a free limited licence is available for development, using the JADE platform requires per-process fees to be paid. Language In syntax, JADE is very similar to Pascal; its syntax is based on the language Modula-2, which was derived from Pascal. While it includes innovations lacking in Pascal or Modula-2, it lacks certain features of other modern object-oriented languages such as C# and Java. JADE is abl ...

Computer Hardware Tuning
A computer is a machine that can be programmed to carry out sequences of arithmetic or logical operations (computation) automatically. Modern digital electronic computers can perform generic sets of operations known as programs. These programs enable computers to perform a wide range of tasks. A computer system is a nominally complete computer that includes the hardware, operating system (main software), and peripheral equipment needed and used for full operation. This term may also refer to a group of computers that are linked and function together, such as a computer network or computer cluster. A broad range of industrial and consumer products use computers as control systems. Simple special-purpose devices like microwave ovens and remote controls are included, as are factory devices like industrial robots and computer-aided design, as well as general-purpose devices like personal computers and mobile devices like smartphones. Computers power the Internet, which lin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
