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, Classic, 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 t ...

Macintosh Performa 5200
Mac is a brand of personal computers designed and marketed by Apple Inc., Apple since 1984. The name is short for Macintosh (its official name until 1999), a reference to the McIntosh (apple), McIntosh apple. The current product lineup includes the MacBook Air and MacBook Pro laptops, and the iMac, Mac Mini, Mac Studio, and Mac Pro desktops. Macs are currently sold with Apple's UNIX-based macOS operating system, which is Proprietary software, not licensed to other manufacturers and exclusively Pre-installed software, bundled with Mac computers. This operating system replaced Apple's original Macintosh operating system, which has variously been named System, Mac OS, and Classic Mac OS. Jef Raskin conceived the Macintosh project in 1979, which was usurped and redefined by Apple co-founder Steve Jobs in 1981. The original Macintosh 128K, Macintosh was launched in January 1984, after Apple's 1984 (advertisement), "1984" advertisement during Super Bowl XVIII. A series of increment ...

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 ...

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 ''programlength 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 and early morning (usually 1:00 a.m. to 9:00 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 ...

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 (M ...

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. The first patented aperture grille televisions were manufactured under the Trinitron brand name. 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 ...

Trinitron
Trinitron was Sony's brand name for its line of aperture-grille-based CRTs used in television sets and computer monitors. It was one of the first television systems to enter the market since the 1950s. 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. The name Trinitron was derived from ''trinity'', meaning the union of three, and ''tron'' from elec''tron'' tube, after the way that the Trinitron combined the three separate electron guns of other CRT designs into one. History Color television Color television had been demonstrable since the 1920s starting with John Logie Baird's system. However, it was only in the late 1940s that it was perfected by both CBS and RCA. At the time, a number of systems were being proposed that used separate red ...

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.
