Master File Table (MFT) NTFS. NTFS (New Technology File System[1]) is a proprietary file system developed by Microsoft.[1] Starting with Windows NT 3.1, it is the default file system of Windows NT family.[7] History[edit] In the mid-1980s, Microsoft and IBM formed a joint project to create the next generation of graphical operating system. The result of the project was OS/2, but Microsoft and IBM disagreed on many important issues and eventually separated: OS/2 remained an IBM project and Microsoft worked on Windows NT.
The OS/2 file system HPFS contained several important new features. When Microsoft created their new operating system, they borrowed many of these concepts for NTFS.[8] Probably as a result of this common ancestry, HPFS and NTFS share the same disk partition identification type code (07). Sharing an ID is unusual, since there were dozens of available codes, and other major file systems have their own code. Developers[edit] NTFS developers include:[9] Versions[edit] Features[edit] Scalability[edit] Fan control. Fan control is the management of the rotational speed of an electric fan.
There are many types of electric fans and many types of fan controls. This article principally describes the control of a computer fan, to provide adequate cooling while reducing noise. Need for fan control[edit] As modern PCs grow more powerful so do their requirements for electrical power. Computers convert most of this electrical power into heat generated by all major components. In fact, if one installs extra fans in a PC case, the noise levels can reach 70 dB. Fan types[edit] The common cooling fans used in computers use standardized connectors with 2 to 4 pins. GroundPower - +12 VSense - a tachometer that measures the actual speed of the fan as a pulse train, frequency being proportional to speed.
The color of the wires connected to these pins varies depending on the number of connectors, but the role of each pin is standardized and guaranteed to be the same on any system. Types of control[edit] Resistors[edit] Surround sound. 10.2 channel surround sound There are various surround sound based formats and techniques, varying in reproduction and recording methods along with the number and positioning of additional channels. Fields of application[edit] Types of media and technologies[edit] Commercial surround sound media include videocassettes, DVDs, and HDTV broadcasts encoded as compressed Dolby Digital and DTS, and lossless audio such as DTS HD Master Audio and Dolby TrueHD on Blu-ray Disc and HD DVD, which are identical to the studio master.
Other commercial formats include the competing DVD-Audio (DVD-A) and Super Audio CD (SACD) formats, and MP3 Surround. Cinema 5.1 surround formats include Dolby Digital and DTS. Sony Dynamic Digital Sound (SDDS) is an 8 channel cinema configuration which features 5 independent audio channels across the front with two independent surround channels, and a Low-frequency effects channel. History[edit] Creating surround sound[edit] Surround sound is created in several ways. Web feed. User interface of a feed reader A web feed (or news feed) is a data format used for providing users with frequently updated content.
Content distributors syndicate a web feed, thereby allowing users to subscribe to it. Making a collection of web feeds accessible in one spot is known as aggregation, which is performed by a news aggregator. A web feed is also sometimes referred to as a syndicated feed. The kinds of content delivered by a web feed are typically HTML (webpage content) or links to webpages and other kinds of digital media. Often when websites provide web feeds to notify users of content updates, they only include summaries in the web feed rather than the full content itself. Web feeds are operated by many news websites, weblogs, schools, and podcasters. Benefits[edit] Web feeds have some advantages compared to receiving frequently published content via an email: Scraping[edit] Usually a web feed is made available by the same entity that created the content.
See also[edit] List of device bit rates. This is a list of device bit rates, or physical layer information rates, net bit rates, useful bit rates, peak bit rates or digital bandwidth capacity, at which digital interfaces of computer peripheral equipment and network devices can communicate over various kinds of buses and networks. Bar chart of common computer interface speeds The distinction can be arbitrary between a bus, (which is inside a box and usually relies on many parallel wires), and a communications network cable, (which is external, between boxes and rarely relies on more than four wires).
Many device interfaces or protocols (e.g., SATA, USB, SCSI, PCI and a few variants of Ethernet) are used both inside many-device boxes, such as a PC, and one-device-boxes, such as a hard drive enclosure. Accordingly, this page lists both the internal ribbon and external communications cable standards together in one sortable table.
