Apple Lisa
Lisa is a desktop computer developed by Apple, released on January 19, 1983. It is one of the first personal computers to present a graphical user interface (GUI) in a machine aimed at individual business users. Its development began in 1978. It underwent many changes before shipping at with a five-megabyte hard drive. It was affected by its high price, insufficient software, unreliable Apple FileWare floppy disks, and the immediate release of the cheaper and faster Macintosh. Only 10,000 were sold in two years. Considered a commercial failure (albeit one with technical acclaim), Lisa introduced a number of advanced features that reappeared on the Macintosh and eventually IBM PC compatibles. Among them is an operating system with protected memory and a document-oriented workflow. The hardware was more advanced overall than the forthcoming Macintosh 128K; the Lisa included hard disk drive support, capacity for up to 2 megabytes (MB) of random-access memory (RAM), expansion ...

Memory Protection
Memory protection is a way to control memory access rights on a computer, and is a part of most modern instruction set architectures and operating systems. The main purpose of memory protection is to prevent a process from accessing memory that has not been allocated to it. This prevents a bug or malware within a process from affecting other processes, or the operating system itself. Protection may encompass all accesses to a specified area of memory, write accesses, or attempts to execute the contents of the area. An attempt to access unauthorized memory results in a hardware fault, e.g., a segmentation fault, storage violation exception, generally causing abnormal termination of the offending process. Memory protection for computer security includes additional techniques such as address space layout randomization and executable space protection. Methods Segmentation Segmentation refers to dividing a computer's memory into segments. A reference to a memory location ...

Pundit
A pundit is a person who offers mass media opinion or commentary on a particular subject area (most typically politics, the social sciences, technology or sport). Origins The term originates from the Sanskrit term ('' '' ), meaning "knowledge owner" or "learned man". It refers to someone who is erudite in various subjects and who conducts religious ceremonies and offers counsel to the king and usually referred to a person from the Hindu Brahmin but may also refer to the siddhas, Siddhars, Naths, ascetics, sadhus, or yogis ( rishi). From at least the early 19th century, a Pundit of the Supreme Court in Colonial India was an officer of the judiciary who advised British judges on questions of Hindu law. In Anglo-Indian use, '' pundit'' also referred to a native of India who was trained and employed by the British to survey inaccessible regions beyond the British frontier. Current use Josef Joffe's book chapter ''The Decline of the Public Intellectual and the Rise ...

Recursive Acronym
A recursive acronym is an acronym that refers to itself, and appears most frequently in computer programming. The term was first used in print in 1979 in Douglas Hofstadter's book '' Gödel, Escher, Bach: An Eternal Golden Braid'', in which Hofstadter invents the acronym GOD, meaning "GOD Over Djinn", to help explain infinite series, and describes it as a recursive acronym. Other references followed, however the concept was used as early as 1968 in John Brunner's science fiction novel '' Stand on Zanzibar''. In the story, the acronym EPT (Education for Particular Task) later morphed into "Eptification for Particular Task". Recursive acronyms typically form backwardly: either an existing ordinary acronym is given a new explanation of what the letters stand for, or a name is turned into an acronym by giving the letters an explanation of what they stand for, in each case with the first letter standing recursively for the whole acronym. Use in computing In computing, an early tradi ...

Backronym
A backronym is an acronym formed from an already existing word by expanding its letters into the words of a phrase. Backronyms may be invented with either serious or humorous intent, or they may be a type of false etymology or folk etymology. The word is a portmanteau of ''back'' and ''acronym''. An acronym is a word derived from the initial letters of the words of a phrase, such as ''radar'' from "''ra''dio ''d''etection ''a''nd ''r''anging". By contrast, a backronym is "an acronym deliberately formed from a phrase whose initial letters spell out a particular word or words, either to create a memorable name or as a fanciful explanation of a word's origin." Many fictional espionage organizations are backronyms, such as SPECTRE (''sp''ecial ''e''xecutive for ''c''ounterintelligence, ''t''errorism, ''r''evenge and ''e''xtortion) from the James Bond franchise. For example, the Amber Alert missing-child program was named after Amber Hagerman, a nine-year-old girl who was abduct ...

Lisa Nicole Brennan-Jobs ( Brennan; born May 17, 1978) is an American writer. She is the daughter of Apple co-founder Steve Jobs and Chrisann Brennan. Jobs initially denied paternity for several years, which led to a legal case and various media reports in the early days of Apple. Lisa and Steve Jobs eventually reconciled, and he accepted his paternity. Brennan-Jobs later worked as a journalist and magazine writer. An early Apple business computer, the Apple Lisa, is named after her, and she has been depicted in a number of biographies and films, including the biopics ''Pirates of Silicon Valley'' (1999), '' Jobs'' (2013), and '' Steve Jobs'' (2015).

Acronym
An acronym is a word or name formed from the initial components of a longer name or phrase. Acronyms are usually formed from the initial letters of words, as in ''NATO'' (''North Atlantic Treaty Organization''), but sometimes use syllables, as in ''Benelux'' (short for ''Belgium, the Netherlands, and Luxembourg''). They can also be a mixture, as in ''radar'' (''Radio Detection And Ranging''). Acronyms can be pronounced as words, like ''NASA'' and ''UNESCO''; as individual letters, like ''FBI'', '' TNT'', and ''ATM''; or as both letters and words, like '' JPEG'' (pronounced ') and ''IUPAC''. Some are not universally pronounced one way or the other and it depends on the speaker's preference or the context in which it is being used, such as '' SQL'' (either "sequel" or "ess-cue-el"). The broader sense of ''acronym''—the meaning of which includes terms pronounced as letters—is sometimes criticized, but it is the term's original meaning and is in common use. Dictionary and ...

Jef Raskin
Jef Raskin (born Jeff Raskin; March 9, 1943 – February 26, 2005) was an American human–computer interface expert best known for conceiving and starting the Macintosh project at Apple in the late 1970s. Early life and education Jef Raskin was born in New York City to a secular Jewish family, whose surname is a matronymic from "Raske", Yiddish nickname for Rachel. He received a BA in mathematics and a BS in physics with minors in philosophy and music from Stony Brook University. In 1967, he received a master's degree in computer science from Pennsylvania State University, after having switched from mathematical logic due to differences of opinion with his advisor. Even though he had completed work for his PhD, the university was not accredited for a PhD in computer science. The first original computer application he wrote was a music application as part of his master's thesis. Raskin later enrolled in a graduate music program at the University of California, San Diego ...

Macintosh
The Mac (known as Macintosh until 1999) is a family of personal computers designed and marketed by 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 first Mac was released in 1984, and was advertised with the highly-acclaimed "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 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 reinvigorated with the introduction of popular high-end Macs and the ongoing Apple si ...
