PowerBook 140
The PowerBook 140 was released in the first line of PowerBooks. It was the mid-range PowerBook, between the low-end 100 and the high-end 170. As with the PowerBook 170, and unlike the 100, this PowerBook featured an internal floppy drive. Codenames for this model are: Tim Lite, Tim LC, Replacements, and Leary. In 1992, it was replaced by the PowerBook 145, which was essentially a speed bump, though the PowerBook 160 essentially superseded it as the new mid-line model. Features Intended as a replacement for the Portable, the 140 series was identical to the 170, though it compromised a number of the high-end model's features to make it a more affordable mid-range option. The most apparent difference was that the 140 used a cheaper, diagonal passive matrix display instead of the sharper active matrix version used on the 170. Internally, in addition to a slower 16 MHz processor, the 140 also lacked a Floating Point Unit (FPU) and could not be upgraded. It also came standard w ...

System 6
System 6 (or System Software 6) is a graphical user interface-based operating system for Macintosh computers, made by Apple Computer It was released in 1988, and is part of the classic Mac OS series. It is a monolithic operating system, with cooperative multitasking based on an improved MultiFinder. The boxed version cost , and it was included with all new Macintosh computers until 1991, when it was succeeded by System 7. Overview MacroMaker The MacroMaker utility was introduced in System 6. It records mouse and keyboard input as macros, and has a unique user interface intended to look and act like a tape recorder. MacroMaker was criticized for its lack of features when compared to Microsoft's AutoMac III, which was already available commercially. As MacroMaker records only the locations of mouse-clicks inside windows and not what is being clicked on or exactly when, it can not be used to automate actions in more sophisticated programs. The pre-recorded clicks miss button ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Floppy Disk
A floppy disk or floppy diskette (casually referred to as a floppy, or a diskette) is an obsolescent type of disk storage composed of a thin and flexible disk of a magnetic storage medium in a square or nearly square plastic enclosure lined with a fabric that removes dust particles from the spinning disk. Floppy disks store digital data which can be read and written when the disk is inserted into a floppy disk drive (FDD) connected to or inside a computer or other device. The first floppy disks, invented and made by IBM, had a disk diameter of . Subsequently, the 5¼-inch and then the 3½-inch became a ubiquitous form of data storage and transfer into the first years of the 21st century. 3½-inch floppy disks can still be used with an external USB floppy disk drive. USB drives for 5¼-inch, 8-inch, and other-size floppy disks are rare to non-existent. Some individuals and organizations continue to use older equipment to read or transfer data from floppy disks.

Hard Disk
A hard disk drive (HDD), hard disk, hard drive, or fixed disk is an electro-mechanical data storage device that stores and retrieves digital data using magnetic storage with one or more rigid rapidly rotating platters coated with magnetic material. The platters are paired with magnetic heads, usually arranged on a moving actuator arm, which read and write data to the platter surfaces. Data is accessed in a random-access manner, meaning that individual blocks of data can be stored and retrieved in any order. HDDs are a type of non-volatile storage, retaining stored data when powered off. Modern HDDs are typically in the form of a small rectangular box. Introduced by IBM in 1956, HDDs were the dominant secondary storage device for general-purpose computers beginning in the early 1960s. HDDs maintained this position into the modern era of servers and personal computers, though personal computing devices produced in large volume, like cell phones and tablets, rely ...

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 Appl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pikes Peak
Pikes Peak is the highest summit of the southern Front Range of the Rocky Mountains, in North America. The ultra-prominent fourteener is located in Pike National Forest, west of downtown Colorado Springs, Colorado. The town of Manitou Springs lies at its base. The mountain is named in honor of American explorer Zebulon Pike (though he was unable to reach the summit). The summit is higher than any point in the United States east of its longitude. Name The band of Ute people who called the Pikes Peak region their home were the Tabeguache, whose name means the "People of Sun Mountain". or "sun", is the Ute word that was given by these first people to the mountain that we now call Pikes Peak. It is thought that the Ute people first arrived in Colorado about 500 A.D., however their oral history states that they were created on Tava. In the 1800s, when the Arapaho people arrived in Colorado, they knew the mountain as meaning "Long Mountain". Throughout its history ...

Megabyte
The megabyte is a multiple of the unit byte for digital information. Its recommended unit symbol is MB. The unit prefix ''mega'' is a multiplier of (106) in the International System of Units (SI). Therefore, one megabyte is one million bytes of information. This definition has been incorporated into the International System of Quantities. In the computer and information technology fields, other definitions have been used that arose for historical reasons of convenience. A common usage has been to designate one megabyte as (220 B), a quantity that conveniently expresses the binary architecture of digital computer memory. The standards bodies have deprecated this usage of the megabyte in favor of a new set of binary prefixes, in which this quantity is designated by the unit mebibyte (MiB). Definitions The unit megabyte is commonly used for 10002 (one million) bytes or 10242 bytes. The interpretation of using base 1024 originated as technical jargon for the byte multiples t ...

US Dollar
The United States dollar ( symbol: $; code: USD; also abbreviated US$ or U.S. Dollar, to distinguish it from other dollar-denominated currencies; referred to as the dollar, U.S. dollar, American dollar, or colloquially buck) is the official currency of the United States and several other countries. The Coinage Act of 1792 introduced the U.S. dollar at par with the Spanish silver dollar, divided it into 100 cents, and authorized the minting of coins denominated in dollars and cents. U.S. banknotes are issued in the form of Federal Reserve Notes, popularly called greenbacks due to their predominantly green color. The monetary policy of the United States is conducted by the Federal Reserve System, which acts as the nation's central bank. The U.S. dollar was originally defined under a bimetallic standard of (0.7735 troy ounces) fine silver or, from 1837, fine gold, or $20.67 per troy ounce. The Gold Standard Act of 1900 linked the dollar solely to gold. From 1934, it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
