Macintosh Performa
The Macintosh Performa is a family of personal computers designed, manufactured and sold by Apple Computer, Inc. from 1992 to 1997. The Performa brand re-used models from Apple's Quadra, Centris, LC, and Power Macintosh families with model numbers that denoted included software packages or hard drive sizes. Whereas non-Performa Macintosh computers were sold by Apple Authorized Resellers, the Performa was sold through big-box stores and mass-market retailers such as Good Guys, Circuit City, and Sears. The initial series of models consisted of the Macintosh Classic II-based Performa 200, the LC II-based Performa 400, and the IIvi-based Performa 600. After releasing a total of sixty-four different models, Apple retired the Performa brand in early 1997, shortly after release of the Power Macintosh 5500, 6500, 8600 and 9600, as well as the return of Steve Jobs to the company. The Performa brand's lifespan coincided with a period of significant financial turmoil at Apple du ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Macintosh Performa 5200
The Mac (known as Macintosh until 1999) is a family of personal computers designed and marketed by Apple Inc., Apple Inc. Macs are known for their ease of use and minimalist designs, and are popular among students, creative professionals, and software engineers. The current lineup includes the MacBook Air and MacBook Pro laptops, as well as the iMac, Mac Mini, Mac Studio and Mac Pro desktops. Macs run the macOS operating system. The Macintosh 128K, first Mac was released in 1984, and was advertised with the highly-acclaimed 1984 (advertisement), "1984" ad. After a period of initial success, the Mac languished in the 1990s, until co-founder Steve Jobs returned to Apple in 1997. Jobs oversaw the release of many successful products, unveiled the modern Mac OS X, completed the Mac transition to Intel processors, 2005-06 Intel transition, and brought features from the iPhone back to the Mac. During Tim Cook's tenure as CEO, the Mac underwent a period of neglect, but was later reinv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Power Macintosh 9600
The Power Macintosh 9600 (also sold with additional server software as the Apple Workgroup Server 9650) is a personal computer that is a part of Apple Computer's Power Macintosh series of Macintosh computers. It was introduced in February 1997 alongside the Power Macintosh 7300 and 8600, and replaced the Power Macintosh 9500 as Apple's flagship desktop computer. The 9600 was replaced by the Power Macintosh G3 Mini Tower in Apple's product lineup in November 1997, with sales of the 9600 continuing until March 1998. Models When introduced, the Power Macintosh 9600 was available with three processor configurations: single-processor 200 MHz, dual-processor 200 MHz, and single-processor 233 MHz. The line was updated in August 1997 with a single-processor 300 MHz or 350 MHz "Mach 5" 604ev with a larger L2 cache, priced at $4,500 and $5,300, respectively. An updated Workgroup Server 9650 was introduced at the same time with a 350 MHz CPU, and could be ordered pre-configured as ...

Infomercial
An infomercial is a form of television commercial that resembles regular TV programming yet is intended to promote or sell a product, service or idea. It generally includes a toll-free telephone number or website. Most often used as a form of direct response television (DRTV), they are often ''program-length commercials'' (long-form infomercials), and are typically 28:30 or 58:30 minutes in length. Infomercials are also known as paid programming (or teleshopping in Europe). This phenomenon started in the United States, where infomercials were typically shown overnight (usually 1:00 a.m. to 6:00 a.m.), outside peak prime time hours for commercial broadcasters. Some television stations chose to air infomercials as an alternative to the former practice of signing off, while other channels air infomercials 24 hours a day. Some stations also choose to air infomercials during the daytime hours, mostly on weekends, to fill in for unscheduled network or syndicated programming. By ...

CPU Cache
A CPU cache is a hardware cache used by the central processing unit (CPU) of a computer to reduce the average cost (time or energy) to access data from the main memory. A cache is a smaller, faster memory, located closer to a processor core, which stores copies of the data from frequently used main memory locations. Most CPUs have a hierarchy of multiple cache levels (L1, L2, often L3, and rarely even L4), with different instruction-specific and data-specific caches at level 1. The cache memory is typically implemented with static random-access memory (SRAM), in modern CPUs by far the largest part of them by chip area, but SRAM is not always used for all levels (of I- or D-cache), or even any level, sometimes some latter or all levels are implemented with eDRAM. Other types of caches exist (that are not counted towards the "cache size" of the most important caches mentioned above), such as the translation lookaside buffer (TLB) which is part of the memory management unit (MMU) w ...

Aperture Grille
An aperture grille is one of two major technologies used to manufacture color cathode-ray tube (CRT) televisions and computer displays; the other is the shadow mask. Fine vertical wires behind the front glass of the display screen separate the different colors of phosphors into strips. These wires are positioned such that an electron beam from one of three guns at the rear of the tube is only able to strike phosphors of the appropriate color. That is, the blue electron gun will strike blue phosphors, but will find a wire blocks the path to red and green phosphors. The fine wires allow for a finer dot pitch as they can be spaced much closer together than the perforations of a shadow mask, and there need be no gap between adjacent horizontal pixels. During the display of bright images, a shadow mask warms, and expands outward in all directions (sometimes called blooming). Aperture grilles do not exhibit this behavior; when the wires heat up, they expand vertically. Because the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trinitron
Trinitron was Sony's brand name for its line of aperture-grille-based CRTs used in television sets and computer monitors. One of the first truly innovative television systems to enter the market since the 1950s, the Trinitron was announced in 1968 to wide acclaim for its bright images, about 25% brighter than common shadow mask televisions of the same era. Constant improvement in the basic technology and attention to overall quality allowed Sony to charge a premium for Trinitron devices into the 1990s. Patent protection on the basic Trinitron design ran out in 1996, and it quickly faced a number of competitors at much lower prices. Sony responded by introducing their flat-screen FD Trinitron designs (WEGA), which maintained their premier position in the market into the early 2000s. However, these designs were surpassed relatively quickly by plasma and LCD designs. Sony removed the last Trinitron televisions from their product catalogs in 2006, and ceased production in early 2 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
à La Carte
In restaurants, ''à la carte'' (; )) is the practice of ordering individual dishes from a menu in a restaurant, as opposed to ''table d'hôte'', where a set menu is offered. It is an early 19th century loan from French meaning "according to the menu".''Oxford English Dictionary'' The individual dishes to be ordered may include side dishes, or the side dishes may be offered separately, in which case, they are also considered ''à la carte''. History The earliest examples of ''à la carte'' are from 1816 for the adjectival use ("à la carte meal", for example) and from 1821 for the adverbial use ("meals were served à la carte"). These pre-date the use of the word menu, which came into English in the 1830s."Menu"''The American Heritage Dictionary of the English Language'' 4th edition, Houghton Mifflin See also * Omakase, Japanese expression for letting the chef decide * ''Table d'hôte'', the opposite of ''à la carte'' * Buffet * List of French words and phrases used by ...

Shadow Mask
The shadow mask is one of the two technologies used in the manufacture of cathode-ray tube (CRT) televisions and computer monitors which produce clear, focused color images. The other approach is the aperture grille, better known by its trade name, Trinitron. All early color televisions and the majority of CRT computer monitors used shadow mask technology. Both of these technologies are largely obsolete, having been increasingly replaced since the 1990s by the liquid-crystal display (LCD). A shadow mask is a metal plate punched with tiny holes that separate the colored phosphors in the layer behind the front glass of the screen. Shadow masks are made by photochemical machining, a technique that allows for the drilling of small holes on metal sheets. Three electron guns at the back of the screen sweep across the mask, with the beams only reaching the screen if they pass through the holes. As the guns are physically separated at the back of the tube, their beams approach th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Macworld
''Macworld'' is a website dedicated to products and software of Apple Inc., published by Foundry, a subsidiary of IDG Inc. It started life as a print magazine in 1984 and had the largest audited circulation (both total and newsstand) of Macintosh-focused magazines in North America, more than double its nearest competitor, ''MacLife'' (formerly ''MacAddict''). ''Macworld'' was founded by David Bunnell and Cheryl Woodard (publishers) and Andrew Fluegelman (editor). It was the oldest Macintosh magazine still in publication, until September 10, 2014, when IDG, its parent company, announced it was discontinuing the print edition and laid off most of the staff, while continuing an online version. History of Macworld In 1997, the publication was renamed ''Macworld, incorporating MacUser'' (a name reflected subtly on the magazine's Table of Contents page) to reflect the consolidation of the Ziff-Davis-owned ''MacUser'' magazine into the International Data Group-owned ''Macworld'' wit ...

Mail Order
Mail order is the buying of goods or services by mail delivery. The buyer places an order for the desired products with the merchant through some remote methods such as: * Sending an order form in the mail * Placing a telephone call * Placing an order with a few travelling agents and paying by installments * Filling in a form on a website or mobile app — if the product information is also mainly obtained online rather than via a paper catalogue or via television, this model is online shopping or e-commerce Then, the products are delivered to the customer. The products are usually delivered directly to an address supplied by the customer, such as a home address, but occasionally the orders are delivered to a nearby retail location for the customer to pick up. Some merchants also allow the goods to be shipped directly to a third party consumer, which is an effective way to send a gift to an out-of-town recipient. Some merchants delivered the goods directly to the customer via t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reseller
A reseller is a company or individual (merchant) that purchases goods or services with the intention of selling them rather than consuming or using them. This is usually done for profit (but can be done at a loss). One example can be found in the industry of telecommunications, where companies buy excess amounts of transmission capacity or call time from other carriers and resell it to smaller carriers. According to the Institute for Partner Education & Development, a reseller's product fulfillment–based business model includes a corporate reseller, retail seller, direct market reseller (DMR), and an internet retailer (eTailer); less than 10 percent of its revenue comes from services. Internet Resellers are known to conduct operations on the Internet through sites on the web. For example, this occurs where individuals or companies act as agents for ICANN accredited registrars. They either sell on commission or for profit and in most cases, but not all, the purchase from the reg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
