Computer Security
Computer security (also cybersecurity, digital security, or information technology (IT) security) is a subdiscipline within the field of information security. It consists of the protection of computer software, systems and computer network, networks from Threat (security), threats that can lead to unauthorized information disclosure, theft or damage to computer hardware, hardware, software, or Data (computing), data, as well as from the disruption or misdirection of the Service (economics), services they provide. The significance of the field stems from the expanded reliance on computer systems, the Internet, and wireless network standards. Its importance is further amplified by the growth of smart devices, including smartphones, televisions, and the various devices that constitute the Internet of things (IoT). Cybersecurity has emerged as one of the most significant new challenges facing the contemporary world, due to both the complexity of information systems and the societi ...

CD-ROM
A CD-ROM (, compact disc read-only memory) is a type of read-only memory consisting of a pre-pressed optical compact disc that contains computer data storage, data computers can read, but not write or erase. Some CDs, called enhanced CDs, hold both computer data and audio with the latter capable of being played on a CD player, while data (such as software or digital video) is only usable on a computer (such as ISO 9660 format PC CD-ROMs). During the 1990s and early 2000s, CD-ROMs were popularly used to distribute software and data for computers and fifth generation video game consoles. DVDs as well as downloading started to replace CD-ROMs in these roles starting in the early 2000s, and the use of CD-ROMs for commercial software is now rare. History The earliest theoretical work on optical disc storage was done by independent researchers in the United States including David Paul Gregg (1958) and James Russell (inventor), James Russel (1965–1975). In particular, Gregg's paten ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Green Book (CD Standard)
The Compact Disc-Interactive (CD-I, later CD-i) is a Digital media, digital optical disc data storage device, data storage format as well as a hardware platform, co-developed and marketed by Dutch company Philips and Japanese company Sony. It was created as an extension of Compact Disc Digital Audio, CDDA and CD-ROM and specified in the ''Rainbow Books, Green Book'' specifications, co-developed by Philips and Sony, to combine audio, text and graphics. The two companies initially expected to impact the education/training, point of sale, and home entertainment industries, but the CD-i is largely remembered today for its video games. CD-i media physically have the same dimensions as CD, but with up to of digital data storage, including up to 72 minutes of full motion video. CD-i players were usually standalone boxes that connect to a standard television; some less common setups included integrated CD-i television sets and expansion modules for personal computers. Most players were ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

CD-i Bridge
The White Book refers to a standard of compact disc that stores not only sound but also still pictures and motion video. It was released in 1993 by Sony, Philips, Matsushita, and JVC. These discs, most commonly found in Asia, are usually called " Video CDs" (VCD). In some ways, VCD can be thought of as the successor to the Laserdisc and the predecessor to DVD. Note that Video CD should not be confused with CD Video which was an earlier and entirely different format. Several extensions to the White Book were published in later years: VCD 2.0 in 1995, VCD-Internet in 1997, and Super Video CD (SVCD) in 1998. The standard is not freely available and must be licensed from Philips. The White Book also defines the more general CD-i Bridge format (also called CD-Bridge or simply "bridge discs"), which are CD-ROM XA discs with an additional Green Book CD-i specific application program. The CD-ROM XA information in bridge discs can be obtained through CD-ROM drives, while CD-i player ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

American Society Of Media Photographers
The American Society of Media Photographers, abbreviated ASMP, is a professional association of imaging professionals, including photojournalism, photojournalists, architectural photographers, architectural, underwater photographers, underwater, food/culinary and advertising photographers as well as video/film makers and other specialists. Its members are primarily those who create images for publications, though many cross over into wedding photography, wedding and portrait photography. ASMP advocates for photographers' legal rights, supports information-sharing among members, and provides business and technical information. Much of the material is freely available to the public. For instance, it offers a web tutorial on registering copyrights, and on model releases and property releases. It also helps users of images find qualified photographers for project assignments ("Find a Photographer") and helps photographers find qualified assistants ("Find an Assistant.") The ASMP has m ...

Kodak
The Eastman Kodak Company, referred to simply as Kodak (), is an American public company that produces various products related to its historic basis in film photography. The company is headquartered in Rochester, New York, and is incorporated in New Jersey. It is best known for photographic film products, which it brought to a mass market for the first time. Kodak began as a partnership between George Eastman and Henry A. Strong to develop a film roll camera. After the release of the Kodak camera, Eastman Kodak was incorporated on May 23, 1892. Under Eastman's direction, the company became one of the world's largest film and camera manufacturers, and also developed a model of welfare capitalism and a close relationship with the city of Rochester. During most of the 20th century, Kodak held a dominant position in photographic film, and produced a number of technological innovations through heavy investment in research and development at Kodak Research Laboratories. Kodak produce ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Photo CD
Photo CD is a system designed by Kodak for digitizing and saving photos onto a CD. Launched in 1991, the discs were designed to hold nearly 100 high quality images, scanned prints and slides using special proprietary encoding. Photo CDs are defined in the Beige Book and conform to the CD-ROM XA and CD-i Bridge specifications as well. They were intended to play on CD-i players, Photo CD players ( Apple's PowerCD for example), and any computer with a suitable software ( LaserSoft Imaging's SilverFast DC or HDR for example). The system failed to gain mass usage among consumers partly due to its proprietary nature, the rapidly decreasing scanner prices, and the lack of CD-ROM drives in most home personal computers of the day. Furthermore, Photo CD relied on CRT-based TV sets for home use. However, these were designed for moving pictures. Their typical flicker became an issue when watching still photographs. The Photo CD system gained a fair level of acceptance among profe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

CD-R
CD-R (Compact disc-recordable) is a digital media, digital optical disc data storage device, storage format. A CD-R disc is a compact disc that can only be Write once read many, written once and read arbitrarily many times. CD-R discs (CD-Rs) are readable by most CD readers manufactured prior to the introduction of CD-R, unlike CD-RW discs. History Originally named CD Write once read many, Write-Once (WO), the CD-R specification was first published in 1988 by Philips and Sony in the Rainbow Books, Orange Book, which consists of several parts that provide details of the CD-WO, CD-MO (Magneto-Optic), and later CD-RW (Re Writable). The latest editions have abandoned the use of the term ''CD-WO'' in favor of ''CD-R'', while ''CD-MO'' was rarely used. Written CD-Rs and CD-RWs are, in the aspect of low-level encoding and data format, fully compatible with the audio CD (''Red Book'' CD-DA) and data CD (''Yellow Book'' CD-ROM) standards. The Yellow Book standard for CD-ROM only speci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
CD-RW
RW (Compact Disc-Rewritable) is a digital media, digital optical disc data storage device, storage format introduced by Ricoh in 1997. A CD-RW compact disc (CD-RWs) can be written, read, erased, and re-written. CD-RWs, as opposed to CDs, require specialized readers that have sensitive laser optics. Consequently, CD-RWs cannot be read in many CD readers built prior to the introduction of CD-RW. CD-ROM drives with a "MultiRead" certification are compatible. CD-RWs must be erased or blanked before reuse. Erasure methods include full blanking where the entire surface of the disc is erased and fast blanking where only metadata areas, such as PMA (CD), PMA, TOC (CD), TOC and pregap, are not cleared. Fast blanking is quicker and usually sufficient to allow rewriting the disc. Full blanking removes all traces of the previous data, and is often used for confidentiality purposes. CD-RWs can sustain fewer re-writes compared to other storage media (ca. 1,000 compared up to 100,000). ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
