Enhanced Write Filter
Enhanced Write Filter (or EWF) is a component of Windows XP Embedded and Windows Embedded Standard 7 which stores Volume (computing), volume changes on another medium instead of applying them to the original volume. EWF allows the writes to be discarded or committed to the original volume later (either directly or through inaction based on the configuration). As this minimizes writes to a specified hard disk, EWF and FBWF (File-Based Write Filter) have become popular in enthusiast computing as a way of decreasing wear of solid-state drives on netbooks and CarPCs. Operating modes EWF has three main operating modes: ''EWF Disk'', ''EWF RAM'', and ''EWF RAM Reg''. In each mode, the location of the EWF volume (which stores the configuration) and the overlay volume (which stores file changes) is different. ''EWF Disk'' stores the overlay data outside the primary disk, allowing an external disk such as a CompactFlash to be used as an overlay. The EWF volume is stored in an Disk partiti ...

Windows XP Embedded
Windows 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. Home and Professional 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. Windows XP Professional offers a number of features unavailable in the Home Edition, including: * The ability to become part of a Windows Server domain, a group of computers that are remotely managed by one or more central servers. * An access control scheme that allows specific permissions on files to be granted to specific users under normal circumstances. However, users can use tools other than Windows Explorer (like cacls or File Manager), or restart to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Windows Embedded Standard 7
Windows IoT, formerly Windows Embedded, is a family of operating systems from Microsoft designed for use in embedded systems. Microsoft currently has three different subfamilies of operating systems for embedded devices targeting a wide market, ranging from small-footprint, real-time devices to point of sale (POS) devices like kiosks. Windows Embedded operating systems are available to original equipment manufacturers (OEMs), who make it available to end users preloaded with their hardware, in addition to volume license customers in some cases. In April 2018, Microsoft released Azure Sphere, another operating system designed for IoT applications running on the Linux kernel. The IoT family Microsoft rebranded "Windows Embedded" to "Windows IoT" starting with the release of embedded editions of Windows 10. Enterprise Windows 10 IoT Enterprise branded editions, version 1809 and older, are binary identical to their respective Windows 10 Enterprise editions – Long-Term Servicing ...

Volume (computing)
In computer data storage, a volume or logical drive is a single accessible storage area with a single file system, typically (though not necessarily) resident on a single partition of a hard disk. Although a volume might be different from a physical disk drive, it can still be accessed with an operating system's logical interface. However, a volume differs from a partition. Differences from partition A volume is not the same thing as a partition. For example, a floppy disk might be accessible as a volume, even though it does not contain a partition, as floppy disks cannot be partitioned with most modern computer software. Also, an OS can recognize a partition without recognizing any volume associated with it, as when the OS cannot interpret the filesystem stored there. This situation occurs, for example, when Windows NT-based OSes encounter disks with non-Microsoft OS partitions, such as the ext3 filesystem commonly used with Linux. Another example occurs in the Intel world w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Enthusiast Computing
Enthusiast computing refers to a group of people who build high-end personal computers that facilitate gaming, stock trading, video editing, music creation and editing, photograph editing, programming, remote work, cryptocurrency mining, and other hardware-intensive applications. Elements of an enthusiast computer may include cutting edge CPU(s), GPU(s), screen(s), cooling devices, cases, motherboard(s), input devices, computer memory, computer storage, virtual reality headsets, network cards, haptics, power supplies, and peripheral devices. Many manufacturers address this market by producing state of the art offerings which can then be integrated into a custom build. Influence of gaming Games have historically been the driving force behind the rapid pace of consumer hardware development. For example, ''The 7th Guest'' and ''Myst'' helped drive the adoption of CD-ROMs.Geoff Keighley"Haunted Glory: The Rise and Fall of Trilobyte" at ''GameSpot'' Intel and AMD both ...

Solid-state Drive
A solid-state drive (SSD) is a solid-state storage device that uses integrated circuit assemblies to store data persistently, typically using flash memory, and functioning as secondary storage in the hierarchy of computer storage. It is also sometimes called a semiconductor storage device, a solid-state device or a solid-state disk, even though SSDs lack the physical spinning disks and movable read–write heads used in hard disk drives (HDDs) and floppy disks. SSD also has rich internal parallelism for data processing. In comparison to hard disk drives and similar electromechanical media which use moving parts, SSDs are typically more resistant to physical shock, run silently, and have higher input/output rates and lower latency. SSDs store data in semiconductor cells. cells can contain between 1 and 4 bits of data. SSD storage devices vary in their properties according to the number of bits stored in each cell, with single-bit cells ("Single Level Cells" or "SLC") ...

Netbook
Netbook was a commonly used term that identified a product class of small and inexpensive laptops which were sold from 2007 to around 2013. These machines were designed primarily as cost-effective tools for consumers to access the Internet from any location before the widespread advent of smartphones, and as a result, generally had lower-end hardware specifications than consumer laptops of the time, being primarily intended as clients for Internet services. While ''netbook'' has fallen out of use, these machines evolved into other products including Google's Chromebook, and mobile devices, particularly tablet computers, often running mobile operating systems such as iOS or Android. At their inception in late 2007, as smaller-than-typical laptop computers optimized for low weight and low cost, netbooks began appearing without certain then-standard laptop features (such as an optical drive), and with less computing power than in full-sized laptops. Later netbooks ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
CompactFlash
CompactFlash (CF) is a flash memory mass storage device used mainly in portable electronic devices. The format was specified and the devices were first manufactured by SanDisk in 1994. CompactFlash became one of the most successful of the early memory card formats, surpassing Miniature Card and SmartMedia. Subsequent formats, such as MMC/ SD, various Memory Stick formats, and xD-Picture Card offered stiff competition. Most of these cards are smaller than CompactFlash while offering comparable capacity and speed. Proprietary memory card formats for use in professional audio and video, such as P2 and SxS, are faster, but physically larger and more costly. CompactFlash's popularity is declining as CFexpress is taking over. As of 2022, both Canon and Nikon newest high end cameras, e.g. the Canon EOS R5, Canon EOS R3, and Nikon Z 9 use CFexpress cards for the higher performance required to record 8K video. Traditional CompactFlash cards use the Parallel ATA interface, but ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Disk Partitioning
Disk partitioning or disk slicing is the creation of one or more regions on secondary storage, so that each region can be managed separately. These regions are called partitions. It is typically the first step of preparing a newly installed disk, before any file system is created. The disk stores the information about the partitions' locations and sizes in an area known as the partition table that the operating system reads before any other part of the disk. Each partition then appears to the operating system as a distinct "logical" disk that uses part of the actual disk. System administrators use a program called a partition editor to create, resize, delete, and manipulate the partitions. Partitioning allows the use of different filesystems to be installed for different kinds of files. Separating user data from system data can prevent the system partition from becoming full and rendering the system unusable. Partitioning can also make backing up easier. A disadvantage is that it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Random-access Memory
Random-access memory (RAM; ) is a form of computer memory that can be read and changed in any order, typically used to store working data and machine code. A random-access memory device allows data items to be read or written in almost the same amount of time irrespective of the physical location of data inside the memory, in contrast with other direct-access data storage media (such as hard disks, CD-RWs, DVD-RWs and the older magnetic tapes and drum memory), where the time required to read and write data items varies significantly depending on their physical locations on the recording medium, due to mechanical limitations such as media rotation speeds and arm movement. RAM contains multiplexing and demultiplexing circuitry, to connect the data lines to the addressed storage for reading or writing the entry. Usually more than one bit of storage is accessed by the same address, and RAM devices often have multiple data lines and are said to be "8-bit" or "16-bit", etc. ...

Windows Registry
The Windows Registry is a hierarchical database that stores low-level settings for the Microsoft Windows operating system and for applications that opt to use the registry. The kernel, device drivers, services, Security Accounts Manager, and user interfaces can all use the registry. The registry also allows access to counters for profiling system performance. In other words, the registry or Windows Registry contains information, settings, options, and other values for programs and hardware installed on all versions of Microsoft Windows operating systems. For example, when a program is installed, a new subkey containing settings such as a program's location, its version, and how to start the program, are all added to the Windows Registry. When introduced with Windows 3.1, the Windows Registry primarily stored configuration information for COM-based components. Windows 95 and Windows NT extended its use to rationalize and centralize the information in the profusion of INI f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
