Sega Net Link
Sega Net Link (also called Sega Saturn Net Link) is an attachment for the Sega Saturn game console to provide Saturn users with internet access and access to email through their console. The unit was released in October 1996. The Sega Net Link fit into the Sega Saturn cartridge port and consisted of a 28.8 kbit/s modem, a custom chip to allow it to interface with the Saturn, and a browser developed by Planetweb, Inc. The unit sold for US$199, or US$400 bundled with a Sega Saturn. In 1997 Sega began selling the NetLink Bundle, which included the standard NetLink plus the compatible games ''Sega Rally Championship'' and '' Virtual On: Cyber Troopers NetLink Edition'', for $99. The Net Link connected to the internet through standard dial-up services. Unlike other online gaming services in the US, one does not connect to a central service, but instead tells the dial-up modem connected to the Saturn's cartridge slot to call to the person with whom one wishes to play.

Kernel (operating System)
The kernel is a computer program at the core of a computer's operating system and generally has complete control over everything in the system. 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 utilization of common resources e.g. CPU & cache usage, 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 usually loaded into a separate area of memory, which is protected from access by applicatio ...

XBAND
XBAND (stylized as XBⱯND) was one of the first competitive online console gaming networks and was available for the Genesis and Super NES. It was produced by Catapult Entertainment in Cupertino, California. It is the only modem released in America to have been officially licensed by Nintendo. It debuted in various areas of the United States in late 1994 and 1995. History The Genesis version of the XBAND was released in November 1994, with the Super NES version following in June 1995, and the Super Famicom version in April 1996. The Genesis version also works with the Genesis Nomad. In Brazil the Mega Drive service was released as the Mega Net 2, named after the Sega Meganet. In 1995, Catapult Entertainment signed a deal with General Instrument, producers of the Sega Channel, which stipulated that the XBAND modem would henceforth be built into new Sega Channel adapters, and that the top 5 to 10 games offered by Sega Channel each month would be playable over XBAND.

Frame (World Wide Web)
In the context of a web browser, a frame is a part of a web page or browser window which displays content independent of its container, with the ability to load content independently. The HTML or media elements shown in a frame may come from a different web site as the other elements of content on display, although this practice, known as framing, is today often regarded as a violation of same-origin policy. In HTML, a frameset is a group of named frames to which web pages and media can be directed; an iframe provides for a frame to be placed inside the body of a document. Since the early 2000s, the use of framesets has been considered obsolete due to usability and accessibility concerns, and the feature has been removed from the HTML5 standard. Tags and attributes The frames in HTML are created using the tag pair. The tag is a container tag for all other tags that are used to create frames. The tag replaces the tag in frameset documents.The tag defines how to divide t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spatial Anti-aliasing
In digital signal processing, spatial anti-aliasing is a technique for minimizing the distortion artifacts ( aliasing) when representing a high-resolution image at a lower resolution. Anti-aliasing is used in digital photography, computer graphics, digital audio, and many other applications. Anti-aliasing means removing signal components that have a higher frequency than is able to be properly resolved by the recording (or sampling) device. This removal is done before (re)sampling at a lower resolution. When sampling is performed without removing this part of the signal, it causes undesirable artifacts such as black-and-white noise. In signal acquisition and audio, anti-aliasing is often done using an analog anti-aliasing filter to remove the out-of-band component of the input signal prior to sampling with an analog-to-digital converter. In digital photography, optical anti-aliasing filters made of birefringent materials smooth the signal in the spatial optical domain. The a ...

C (programming Language)
C (''pronounced like the letter c'') is a General-purpose language, general-purpose computer programming language. It was created in the 1970s by Dennis Ritchie, and remains very widely used and influential. By design, C's features cleanly reflect the capabilities of the targeted CPUs. It has found lasting use in operating systems, device drivers, protocol stacks, though decreasingly for application software. C is commonly used on computer architectures that range from the largest supercomputers to the smallest microcontrollers and embedded systems. A successor to the programming language B (programming language), B, C was originally developed at Bell Labs by Ritchie between 1972 and 1973 to construct utilities running on Unix. It was applied to re-implementing the kernel of the Unix operating system. During the 1980s, C gradually gained popularity. It has become one of the measuring programming language popularity, most widely used programming languages, with C compilers avail ...

Emap International Limited
Ascential plc, formerly EMAP, is a British business-to-business media business specialising in exhibitions & festivals and information services. It is listed on the London Stock Exchange and is a constituent of the FTSE 250 Index. History Richard Winfrey purchased the ''Spalding Guardian'' in 1887 and later purchased the '' Lynn News'' and the '' Peterborough Advertiser''; he also started the ''North Cambs Echo''. He became a Liberal politician and campaigner for agricultural rights and the papers were used to promote his political views in and around Spalding, Boston, Sleaford and Peterborough. During World War II Winfrey's newspaper interests began to be passed over to his son, Richard Pattinson Winfrey (1902–1985). In 1947, under the direction of 'Pat' Winfrey, the family's newspaper titles were consolidated to form the East Midland Allied Press (EMAP): this was achieved by the merger of the Northamptonshire Printing and Publishing Co., the Peterborough Advertiser Co., th ...

Smartcards
A smart card, chip card, or integrated circuit card (ICC or IC card) is a physical electronic authentication device, used to control access to a resource. It is typically a plastic credit card-sized card with an embedded integrated circuit (IC) chip. Many smart cards include a pattern of metal contacts to electrically connect to the internal chip. Others are contactless, and some are both. Smart cards can provide personal identification, authentication, data storage, and application processing. Applications include identification, financial, mobile phones (SIM), public transit, computer security, schools, and healthcare. Smart cards may provide strong security authentication for single sign-on (SSO) within organizations. Numerous nations have deployed smart cards throughout their populations. The universal integrated circuit card, or SIM card, is also a type of smart card. , 10.5billion smart card IC chips are manufactured annually, including 5.44billion SIM card IC chips. Hist ...

Bookmark (World Wide Web)
In the context of the World Wide Web, a bookmark is a Uniform Resource Identifier (URI) that is stored for later retrieval in any of various storage formats. All modern web browsers include bookmark features. Bookmarks are called favorites or Internet shortcuts in Internet Explorer and Microsoft Edge, and by virtue of that browser's large market share, these terms have been synonymous with ''bookmark'' since the First Browser War. Bookmarks are normally accessed through a menu in the user's web browser, and folders are commonly used for organization. In addition to bookmarking methods within most browsers, many external applications offer bookmark management. Bookmarks have been incorporated in browsers since the ViolaWWW browser in 1992, and Mosaic browser in 1993. Bookmark lists were called ''Hotlists'' in Mosaic and in previous versions of Opera; this term has faded from common use. Cello, another early browser, also had bookmarking features. With the advent of social bo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Static RAM
Static random-access memory (static RAM or SRAM) is a type of random-access memory (RAM) that uses latching circuitry (flip-flop) to store each bit. SRAM is volatile memory; data is lost when power is removed. The term ''static'' differentiates SRAM from DRAM (''dynamic'' random-access memory) — SRAM will hold its data permanently in the presence of power, while data in DRAM decays in seconds and thus must be periodically refreshed. SRAM is faster than DRAM but it is more expensive in terms of silicon area and cost; it is typically used for the cache and internal registers of a CPU while DRAM is used for a computer's main memory. History Semiconductor bipolar SRAM was invented in 1963 by Robert Norman at Fairchild Semiconductor. MOS SRAM was invented in 1964 by John Schmidt at Fairchild Semiconductor. It was a 64-bit MOS p-channel SRAM. The SRAM was the main driver behind any new CMOS-based technology fabrication process since 1959 when CMOS was invented. In 1965, ...
