The Macintosh is a family of personal computers designed and sold by Apple Inc. since January 1984. The original Macintosh was the first mass-market personal computer that featured a graphical user interface, built-in screen and mouse. Apple sold the Macintosh alongside its popular Apple II family of computers for ten years before they were discontinued in 1993. Early Macintosh models were expensive, hindering its competitiveness in a market dominated by the Commodore 64 for consumers, as well as the IBM Personal Computer and its accompanying clone market for businesses. Macintosh systems still found success in education and desktop publishing and kept Apple as the second-largest PC manufacturer for the next decade. In the early 1990s, Apple introduced models such as the Macintosh LC II and Color Classic which were price-competitive with Wintel machines at the time. However, the introduction of Windows 3.1 and Intel's Pentium processor which beat the Motorola 68040 in most benchmarks took market share from Apple, by the end of 1994 Apple was relegated to third place as Compaq became the top PC manufacturer.
After the transition to the superior PowerPC-based Power Macintosh line in the mid-1990s, the falling prices of commodity PC components, poor inventory management with the Macintosh Performa, the release of Windows 95 saw the Macintosh user base decline. Prompted by the returning Steve Jobs' belief that the Macintosh line had become too complex, Apple consolidated nearly twenty models in mid-1997 down to four in mid-1999: The Power Macintosh G3, iMac, 14.1" PowerBook G3, 12" iBook. All four products were critically and commercially successful due to their high performance, competitive prices and aesthetic designs, helped return Apple to profitability. Around this time, Apple phased out the Macintosh name in favor of "Mac", a nickname, in common use since the development of the first model. Since their transition to Intel processors in 2006, the complete lineup is based on said processors and associated systems, its current lineup includes four desktops, three laptops. Its Xserve server was discontinued in 2011 in favor of the Mac Mac Pro.
Apple has developed a series of Macintosh operating systems. The first versions had no name but came to be known as the "Macintosh System Software" in 1988, "Mac OS" in 1997 with the release of Mac OS 7.6, retrospectively called "Classic Mac OS". In 2001, Apple released Mac OS X, a modern Unix-based operating system, rebranded to OS X in 2012, macOS in 2016; the current version is macOS Mojave, released on September 24, 2018. Intel-based Macs are capable of running non-Apple operating systems such as Linux, OpenBSD, Microsoft Windows with the aid of Boot Camp or third-party software. Apple produced a Unix-based operating system for the Macintosh called A/UX from 1988 to 1995, which resembled contemporary versions of the Macintosh system software. Apple does not license macOS for use on non-Apple computers, however System 7 was licensed to various companies through Apple's Macintosh clone program from 1995 to 1997. Only one company, UMAX Technologies was licensed to ship clones running Mac OS 8.
Since Apple's transition to Intel processors, there is a sizeable community around the world that specialises in hacking macOS to run on non-Apple computers, which are called "Hackintoshes". The Macintosh project began in 1979 when Jef Raskin, an Apple employee, envisioned an easy-to-use, low-cost computer for the average consumer, he wanted to name the computer after his favorite type of apple, the McIntosh, but the spelling was changed to "Macintosh" for legal reasons as the original was the same spelling as that used by McIntosh Laboratory, Inc. the audio equipment manufacturer. Steve Jobs requested that McIntosh Laboratory give Apple a release for the newly spelled name, thus allowing Apple to use it; the request was denied, forcing Apple to buy the rights to use this name. In 1978, Apple began to organize the Apple Lisa project, aiming to build a next-generation machine similar to an advanced Apple II or the yet-to-be-introduced IBM PC. In 1979, Steve Jobs learned of the advanced work on graphical user interfaces taking place at Xerox PARC.
He arranged for Apple engineers to be allowed to visit PARC to see the systems in action. The Apple Lisa project was redirected to utilize a GUI, which at that time was well beyond the state of the art for microprocessor capabilities. Things had changed with the introduction of the 32-bit Motorola 68000 in 1979, which offered at least an order of magnitude better performance than existing designs, made a software GUI machine a practical possibility; the basic layout of the Lisa was complete by 1982, at which point Jobs's continual suggestions for improvements led to him being kicked off the project. At the same time that the Lisa was becoming a GUI machine in 1979, Jef Raskin started the Macintosh project; the design at that time was for a easy-to-use machine for the average consumer. In
A database is an organized collection of data stored and accessed electronically from a computer system. Where databases are more complex they are developed using formal design and modeling techniques; the database management system is the software that interacts with end users and the database itself to capture and analyze the data. The DBMS software additionally encompasses; the sum total of the database, the DBMS and the associated applications can be referred to as a "database system". The term "database" is used to loosely refer to any of the DBMS, the database system or an application associated with the database. Computer scientists may classify database-management systems according to the database models that they support. Relational databases became dominant in the 1980s; these model data as rows and columns in a series of tables, the vast majority use SQL for writing and querying data. In the 2000s, non-relational databases became popular, referred to as NoSQL because they use different query languages.
Formally, a "database" refers to the way it is organized. Access to this data is provided by a "database management system" consisting of an integrated set of computer software that allows users to interact with one or more databases and provides access to all of the data contained in the database; the DBMS provides various functions that allow entry and retrieval of large quantities of information and provides ways to manage how that information is organized. Because of the close relationship between them, the term "database" is used casually to refer to both a database and the DBMS used to manipulate it. Outside the world of professional information technology, the term database is used to refer to any collection of related data as size and usage requirements necessitate use of a database management system. Existing DBMSs provide various functions that allow management of a database and its data which can be classified into four main functional groups: Data definition – Creation and removal of definitions that define the organization of the data.
Update – Insertion and deletion of the actual data. Retrieval – Providing information in a form directly usable or for further processing by other applications; the retrieved data may be made available in a form the same as it is stored in the database or in a new form obtained by altering or combining existing data from the database. Administration – Registering and monitoring users, enforcing data security, monitoring performance, maintaining data integrity, dealing with concurrency control, recovering information, corrupted by some event such as an unexpected system failure. Both a database and its DBMS conform to the principles of a particular database model. "Database system" refers collectively to the database model, database management system, database. Physically, database servers are dedicated computers that hold the actual databases and run only the DBMS and related software. Database servers are multiprocessor computers, with generous memory and RAID disk arrays used for stable storage.
RAID is used for recovery of data. Hardware database accelerators, connected to one or more servers via a high-speed channel, are used in large volume transaction processing environments. DBMSs are found at the heart of most database applications. DBMSs may be built around a custom multitasking kernel with built-in networking support, but modern DBMSs rely on a standard operating system to provide these functions. Since DBMSs comprise a significant market and storage vendors take into account DBMS requirements in their own development plans. Databases and DBMSs can be categorized according to the database model that they support, the type of computer they run on, the query language used to access the database, their internal engineering, which affects performance, scalability and security; the sizes and performance of databases and their respective DBMSs have grown in orders of magnitude. These performance increases were enabled by the technology progress in the areas of processors, computer memory, computer storage, computer networks.
The development of database technology can be divided into three eras based on data model or structure: navigational, SQL/relational, post-relational. The two main early navigational data models were the hierarchical model and the CODASYL model The relational model, first proposed in 1970 by Edgar F. Codd, departed from this tradition by insisting that applications should search for data by content, rather than by following links; the relational model employs sets of ledger-style tables, each used for a different type of entity. Only in the mid-1980s did computing hardware become powerful enough to allow the wide deployment of relational systems. By the early 1990s, relational systems dominated in all large-scale data processing applications, as of 2018 they remain dominant: IBM DB2, Oracle, MySQL, Microsoft SQL Server are the most searched DBMS; the dominant database language, standardised SQL for the relational model, has influenced database languages for other data models. Object databases were developed in the 1980s to overcome the inconvenience of object-relational impedance mismatch, which led to the coining of the term "post-relational" and the development of hybrid object-relational databas
Unix is a family of multitasking, multiuser computer operating systems that derive from the original AT&T Unix, development starting in the 1970s at the Bell Labs research center by Ken Thompson, Dennis Ritchie, others. Intended for use inside the Bell System, AT&T licensed Unix to outside parties in the late 1970s, leading to a variety of both academic and commercial Unix variants from vendors including University of California, Microsoft, IBM, Sun Microsystems. In the early 1990s, AT&T sold its rights in Unix to Novell, which sold its Unix business to the Santa Cruz Operation in 1995; the UNIX trademark passed to The Open Group, a neutral industry consortium, which allows the use of the mark for certified operating systems that comply with the Single UNIX Specification. As of 2014, the Unix version with the largest installed base is Apple's macOS. Unix systems are characterized by a modular design, sometimes called the "Unix philosophy"; this concept entails that the operating system provides a set of simple tools that each performs a limited, well-defined function, with a unified filesystem as the main means of communication, a shell scripting and command language to combine the tools to perform complex workflows.
Unix distinguishes itself from its predecessors as the first portable operating system: the entire operating system is written in the C programming language, thus allowing Unix to reach numerous platforms. Unix was meant to be a convenient platform for programmers developing software to be run on it and on other systems, rather than for non-programmers; the system grew larger as the operating system started spreading in academic circles, as users added their own tools to the system and shared them with colleagues. At first, Unix was not designed to be multi-tasking. Unix gained portability, multi-tasking and multi-user capabilities in a time-sharing configuration. Unix systems are characterized by various concepts: the use of plain text for storing data; these concepts are collectively known as the "Unix philosophy". Brian Kernighan and Rob Pike summarize this in The Unix Programming Environment as "the idea that the power of a system comes more from the relationships among programs than from the programs themselves".
In an era when a standard computer consisted of a hard disk for storage and a data terminal for input and output, the Unix file model worked quite well, as I/O was linear. In the 1980s, non-blocking I/O and the set of inter-process communication mechanisms were augmented with Unix domain sockets, shared memory, message queues, semaphores, network sockets were added to support communication with other hosts; as graphical user interfaces developed, the file model proved inadequate to the task of handling asynchronous events such as those generated by a mouse. By the early 1980s, users began seeing Unix as a potential universal operating system, suitable for computers of all sizes; the Unix environment and the client–server program model were essential elements in the development of the Internet and the reshaping of computing as centered in networks rather than in individual computers. Both Unix and the C programming language were developed by AT&T and distributed to government and academic institutions, which led to both being ported to a wider variety of machine families than any other operating system.
Under Unix, the operating system consists of many libraries and utilities along with the master control program, the kernel. The kernel provides services to start and stop programs, handles the file system and other common "low-level" tasks that most programs share, schedules access to avoid conflicts when programs try to access the same resource or device simultaneously. To mediate such access, the kernel has special rights, reflected in the division between user space and kernel space - although in microkernel implementations, like MINIX or Redox, functions such as network protocols may run in user space; the origins of Unix date back to the mid-1960s when the Massachusetts Institute of Technology, Bell Labs, General Electric were developing Multics, a time-sharing operating system for the GE-645 mainframe computer. Multics featured several innovations, but presented severe problems. Frustrated by the size and complexity of Multics, but not by its goals, individual researchers at Bell Labs started withdrawing from the project.
The last to leave were Ken Thompson, Dennis Ritchie, Douglas McIlroy, Joe Ossanna, who decided to reimplement their experiences in a new project of smaller scale. This new operating system was without organizational backing, without a name; the new operating system was a single-tasking system. In 1970, the group coined the name Unics for Uniplexed Information and Computing Service, as a pun on Multics, which stood for Multiplexed Information and Computer Services. Brian Kernighan takes credit for the idea, but adds that "no one can remember" the origin of the final spelling Unix. Dennis Ritchie, Doug McIlroy, Peter G. Neumann credit Kernighan; the operating system was written in assembly language, but in 1973, Version 4 Unix was rewritten in C. Version 4 Unix, still had many PDP-11 dependent codes, is not suitable for porting; the first port to other platform was made five years f
Hypertext is text displayed on a computer display or other electronic devices with references to other text that the reader can access. Hypertext documents are interconnected by hyperlinks, which are activated by a mouse click, keypress set or by touching the screen. Apart from text, the term "hypertext" is sometimes used to describe tables and other presentational content formats with integrated hyperlinks. Hypertext is one of the key underlying concepts of the World Wide Web, where Web pages are written in the Hypertext Markup Language; as implemented on the Web, hypertext enables the easy-to-use publication of information over the Internet.'Hypertext' is a recent coinage.'Hyper-' is used in the mathematical sense of extension and generality rather than the medical sense of'excessive'. There is no implication about size— a hypertext could contain only 500 words or so.'Hyper-' refers to structure and not size. The English prefix "hyper-" comes from the Greek prefix "ὑπερ-" and means "over" or "beyond".
It signifies the overcoming of the previous linear constraints of written text. The term "hypertext" is used where the term "hypermedia" might seem appropriate. In 1992, author Ted Nelson – who coined both terms in 1963 – wrote: By now the word "hypertext" has become accepted for branching and responding text, but the corresponding word "hypermedia", meaning complexes of branching and responding graphics and sound – as well as text – is much less used. Instead they use the strange term "interactive multimedia": this is four syllables longer, does not express the idea of extending hypertext. Hypertext documents can either be dynamic. Static hypertext can be used to cross-reference collections of data in documents, software applications, or books on CDs. A well-constructed system can incorporate other user-interface conventions, such as menus and command lines. Links used in a hypertext document replace the current piece of hypertext with the destination document. A lesser known feature is StretchText, which expands or contracts the content in place, thereby giving more control to the reader in determining the level of detail of the displayed document.
Some implementations support transclusion, where text or other content is included by reference and automatically rendered in place. Hypertext can be used to support complex and dynamic systems of linking and cross-referencing; the most famous implementation of hypertext is the World Wide Web, written in the final months of 1990 and released on the Internet in 1991. In 1941, Jorge Luis Borges published "The Garden of Forking Paths", a short story, considered an inspiration for the concept of hypertext. In 1945, Vannevar Bush wrote an article in The Atlantic Monthly called "As We May Think", about a futuristic proto-hypertext device he called a Memex. A Memex would hypothetically store - and record - content on reels of microfilm, using electric photocells to read coded symbols recorded next to individual microfilm frames while the reels spun at high speed, stopping on command; the coded symbols would enable the Memex to index and link content to create and follow associative trails. Because the Memex was never implemented and could only link content in a crude fashion — by creating chains of entire microfilm frames — the Memex is now regarded not only as a proto-hypertext device, but it is fundamental to the history of hypertext because it directly inspired the invention of hypertext by Ted Nelson and Douglas Engelbart.
In 1963, Ted Nelson coined the terms'hypertext' and'hypermedia' as part of a model he developed for creating and using linked content. He worked with Andries van Dam to develop the Hypertext Editing System in 1967 at Brown University. By 1976, its successor FRESS was used in a poetry class in which students could browse a hyperlinked set of poems and discussion by experts and other students, in what was arguably the world’s first online scholarly community which van Dam says "foreshadowed wikis and communal documents of all kinds". Ted Nelson said in the 1960s that he began implementation of a hypertext system he theorized, named Project Xanadu, but his first and incomplete public release was finished much in 1998. Douglas Engelbart independently began working on his NLS system in 1962 at Stanford Research Institute, although delays in obtaining funding and equipment meant that its key features were not completed until 1968. In December of that year, Engelbart demonstrated a'hypertext' interface to the public for the first time, in what has come to be known as "The Mother of All Demos".
The first hypermedia application is considered to be the Aspen Movie Map, implemented in 1978. The Movie Map allowed users to arbitrarily choose which way they wished to drive in a virtual cityscape, in two seasons as well as 3-D polygons. In 1980, Tim Berners-Lee created ENQUIRE, an early hypertext database system somewhat like a wiki but without hypertext punctuation, not invented until 1987; the early 1980s saw a number of experimental "hyperediting" functions in word processors and hypermedia programs, many of whose features and terminology were analogous to the World Wide Web. Guide, the first significant hypertext system for personal computers, was developed by Peter J. Brown at UKC in 1982. In 1980 Roberto Busa, an Italian Jesuit priest and one of the pioneers in the usage of
Hard disk drive
A hard disk drive, hard disk, hard drive, or fixed disk, is an electromechanical data storage device that uses magnetic storage to store and retrieve digital information using one or more rigid rotating disks coated with magnetic material. The platters are paired with magnetic heads 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 or retrieved in any order and not only sequentially. HDDs are a type of non-volatile storage, retaining stored data when powered off. Introduced by IBM in 1956, HDDs became the dominant secondary storage device for general-purpose computers by the early 1960s. Continuously improved, HDDs have maintained this position into the modern era of servers and personal computers. More than 200 companies have produced HDDs though after extensive industry consolidation most units are manufactured by Seagate and Western Digital. HDDs dominate the volume of storage produced for servers.
Though production is growing sales revenues and unit shipments are declining because solid-state drives have higher data-transfer rates, higher areal storage density, better reliability, much lower latency and access times. The revenues for SSDs, most of which use NAND exceed those for HDDs. Though SSDs have nearly 10 times higher cost per bit, they are replacing HDDs in applications where speed, power consumption, small size, durability are important; the primary characteristics of an HDD are its performance. Capacity is specified in unit prefixes corresponding to powers of 1000: a 1-terabyte drive has a capacity of 1,000 gigabytes; some of an HDD's capacity is unavailable to the user because it is used by the file system and the computer operating system, inbuilt redundancy for error correction and recovery. There is confusion regarding storage capacity, since capacities are stated in decimal Gigabytes by HDD manufacturers, whereas some operating systems report capacities in binary Gibibytes, which results in a smaller number than advertised.
Performance is specified by the time required to move the heads to a track or cylinder adding the time it takes for the desired sector to move under the head, the speed at which the data is transmitted. The two most common form factors for modern HDDs are 3.5-inch, for desktop computers, 2.5-inch for laptops. HDDs are connected to systems by standard interface cables such as SATA, USB or SAS cables; the first production IBM hard disk drive, the 350 disk storage, shipped in 1957 as a component of the IBM 305 RAMAC system. It was the size of two medium-sized refrigerators and stored five million six-bit characters on a stack of 50 disks. In 1962, the IBM 350 was superseded by the IBM 1301 disk storage unit, which consisted of 50 platters, each about 1/8-inch thick and 24 inches in diameter. While the IBM 350 used only two read/write heads, the 1301 used an array of heads, one per platter, moving as a single unit. Cylinder-mode read/write operations were supported, the heads flew about 250 micro-inches above the platter surface.
Motion of the head array depended upon a binary adder system of hydraulic actuators which assured repeatable positioning. The 1301 cabinet was about the size of three home refrigerators placed side by side, storing the equivalent of about 21 million eight-bit bytes. Access time was about a quarter of a second. In 1962, IBM introduced the model 1311 disk drive, about the size of a washing machine and stored two million characters on a removable disk pack. Users could interchange them as needed, much like reels of magnetic tape. Models of removable pack drives, from IBM and others, became the norm in most computer installations and reached capacities of 300 megabytes by the early 1980s. Non-removable HDDs were called "fixed disk" drives; some high-performance HDDs were manufactured with one head per track so that no time was lost physically moving the heads to a track. Known as fixed-head or head-per-track disk drives they were expensive and are no longer in production. In 1973, IBM introduced a new type of HDD code-named "Winchester".
Its primary distinguishing feature was that the disk heads were not withdrawn from the stack of disk platters when the drive was powered down. Instead, the heads were allowed to "land" on a special area of the disk surface upon spin-down, "taking off" again when the disk was powered on; this reduced the cost of the head actuator mechanism, but precluded removing just the disks from the drive as was done with the disk packs of the day. Instead, the first models of "Winchester technology" drives featured a removable disk module, which included both the disk pack and the head assembly, leaving the actuator motor in the drive upon removal. "Winchester" drives abandoned the removable media concept and returned to non-removable platters. Like the first removable pack drive, the first "Winchester" drives used platters 14 inches in diameter. A few years designers were exploring the possibility that physically smaller platters might offer advantages. Drives with non-removable eight-inch platters appeared, drives that used a 5 1⁄4 in form factor.
The latter were intended for the then-fl
In computing, a hyperlink, or a link, is a reference to data that the reader can directly follow either by clicking or tapping. A hyperlink points to a specific element within a document. Hypertext is text with hyperlinks; the text, linked from is called anchor text. A software system, used for viewing and creating hypertext is a hypertext system, to create a hyperlink is to hyperlink. A user following hyperlinks is said to browse the hypertext; the document containing a hyperlink is known as its source document. For example, in an online reference work such as Wikipedia, or Google, many words and terms in the text are hyperlinked to definitions of those terms. Hyperlinks are used to implement reference mechanisms such as tables of contents, bibliographies, indexes and glossaries. In some hypertext hyperlinks can be bidirectional: they can be followed in two directions, so both ends act as anchors and as targets. More complex arrangements exist, such as many-to-many links; the effect of following a hyperlink may vary with the hypertext system and may sometimes depend on the link itself.
Another possibility is transclusion, for which the link target is a document fragment that replaces the link anchor within the source document. Not only persons browsing the document follow hyperlinks; these hyperlinks may be followed automatically by programs. A program that traverses the hypertext, following each hyperlink and gathering all the retrieved documents is known as a Web spider or crawler. An inline link displays remote content without the need for embedding the content; the remote content may be accessed without the user selecting the link. An inline link may display a modified version of the content; the full content is usually available on demand, as is the case with print publishing software – e.g. with an external link. This allows for smaller file sizes and quicker response to changes when the full linked content is not needed, as is the case when rearranging a page layout. An anchor hyperlink is a link bound to a portion of a document—generally text, though not necessarily. For instance, it may be a hot area in an image, a designated irregular part of an image.
One way to define it is by a list of coordinates. For example, a political map of Africa may have each country hyperlinked to further information about that country. A separate invisible hot area interface allows for swapping skins or labels within the linked hot areas without repetitive embedding of links in the various skin elements. A fat link or a "multi-tailed link" is a hyperlink. Tim Berners-Lee saw the possibility of using hyperlinks to link any information to any other information over the Internet. Hyperlinks were therefore integral to the creation of the World Wide Web. Web pages are written in the hypertext mark-up language HTML; this is what a hyperlink to the home page of the W3C organization could look like in HTML code: This HTML code consists of several tags: The hyperlink starts with an anchor opening tag <a, includes a hyperlink reference href="http://www.w3.org" to the URL for the page. The URL is followed by >. The words that follow identify; these words are underlined and colored.
The anchor closing tag terminates the hyperlink code. Webgraph is a graph, formed from web pages as hyperlinks, as directed edges; the W3C Recommendation called XLink describes hyperlinks that offer a far greater degree of functionality than those offered in HTML. These extended links can be multidirectional, linking from and between XML documents, it can describe simple links, which are unidirectional and therefore offer no more functionality than hyperlinks in HTML. While wikis may use HTML-type hyperlinks, the use of wiki markup, a set of lightweight markup languages for wikis, provides simplified syntax for linking pages within wiki environments—in other words, for creating wikilinks; the syntax and appearance of wikilinks may vary. Ward Cunningham's original wiki software, the WikiWikiWeb used CamelCase for this purpose. CamelCase was used in the early version of Wikipedia and is still used in some wikis, such as TiddlyWiki, PmWiki. A common markup syntax is the use of double square brackets around the term to be wikilinked.
For example, the input "" is converted by wiki software using this markup syntax to a link to a zebras article. Hyperlinks used in wikis are classified as follows: Internal wikilinks or intrawiki links lead to pages within the same wiki website. Interwiki links are simplified markup hyperlinks that lead to pages of other wikis that are associated with the first. External links lead to other webpages. Wikilinks are visibly distinct from other text, if an internal wikilink leads to a page th
Brown University is a private Ivy League research university in Providence, Rhode Island. Founded in 1764 as the College in the English Colony of Rhode Island and Providence Plantations, it is the seventh-oldest institution of higher education in the United States and one of the nine colonial colleges chartered before the American Revolution. At its foundation, Brown was the first college in the U. S. to accept students regardless of their religious affiliation. Its engineering program was established in 1847, it was one of the early doctoral-granting U. S. institutions in the late 19th century, adding masters and doctoral studies in 1887. In 1969, Brown adopted a New Curriculum sometimes referred to as the Brown Curriculum after a period of student lobbying; the New Curriculum eliminated mandatory "general education" distribution requirements, made students "the architects of their own syllabus" and allowed them to take any course for a grade of satisfactory or unrecorded no-credit. In 1971, Brown's coordinate women's institution, Pembroke College, was merged into the university.
Undergraduate admissions is selective, with an acceptance rate of 6.6% for the class of 2023. The university comprises the College, the Graduate School, Alpert Medical School, the School of Engineering, the School of Public Health and the School of Professional Studies. Brown's international programs are organized through the Watson Institute for International and Public Affairs, the university is academically affiliated with the Marine Biological Laboratory and the Rhode Island School of Design; the Brown/RISD Dual Degree Program, offered in conjunction with the Rhode Island School of Design, is a five-year course that awards degrees from both institutions. Brown's main campus is located in the College Hill Historic District in the city of Providence, Rhode Island; the University's neighborhood is a federally listed architectural district with a dense concentration of Colonial-era buildings. Benefit Street, on the western edge of the campus, contains "one of the finest cohesive collections of restored seventeenth- and eighteenth-century architecture in the United States".
As of August 2018, 8 Nobel Prize winners have been affiliated with Brown University as alumni, faculty members or researchers. In addition, Brown's faculty and alumni include five National Humanities Medalists and ten National Medal of Science laureates. Other notable alumni include eight billionaire graduates, a U. S. Supreme Court Chief Justice, four U. S. Secretaries of State and other Cabinet officials, 54 members of the United States Congress, 56 Rhodes Scholars, 52 Gates Cambridge Scholars 49 Marshall Scholars, 14 MacArthur Genius Fellows, 21 Pulitzer Prize winners, various royals and nobles, as well as leaders and founders of Fortune 500 companies; the origin of Brown University can be dated to 1761, when three residents of Newport, Rhode Island drafted a petition to the General Assembly of the colony: Your Petitioners propose to open a literary institution or School for instructing young Gentlemen in the Languages, Geography & History, & such other branches of Knowledge as shall be desired.
That for this End... it will be necessary... to erect a public Building or Buildings for the boarding of the youth & the Residence of the Professors. The three petitioners were Ezra Stiles, pastor of Newport's Second Congregational Church and future president of Yale. Stiles and Ellery were co-authors of the Charter of the College two years later; the editor of Stiles's papers observes, "This draft of a petition connects itself with other evidence of Dr. Stiles's project for a Collegiate Institution in Rhode Island, before the charter of what became Brown University."There is further documentary evidence that Stiles was making plans for a college in 1762. On January 20, Chauncey Whittelsey, pastor of the First Church of New Haven, answered a letter from Stiles: The week before last I sent you the Copy of Yale College Charter... Should you make any Progress in the Affair of a Colledge, I should be glad to hear of it; the Philadelphia Association of Baptist Churches had an eye on Rhode Island, home of the mother church of their denomination: the First Baptist Church in America, founded in Providence in 1638 by Roger Williams.
The Baptists were as yet unrepresented among colonial colleges. Isaac Backus was the historian of the New England Baptists and an inaugural Trustee of Brown, writing in 1784, he described the October 1762 resolution taken at Philadelphia: The Philadelphia Association obtained such an acquaintance with our affairs, as to bring them to an apprehension that it was practicable and expedient to erect a college in the Colony of Rhode-Island, under the chief direction of the Baptists. Mr. James Manning, who took his first degree in New-Jersey college in September, 1762, was esteemed a suitable leader in this important work. Manning arrived at Newport in July 1763 and was introduced to Stiles, who agreed to write the Charter for the College. Stiles's first draft was read to the General Assembly in August 1763 and rejected by Baptist members who worried that the College Board of Fellows would under-represent the Baptists. A revised Charter written by Stiles and Ellery was adopted by the Assembly on March 3, 1764.
In September 1764, the inaugural meeting of the College Corporation was held at Newport. Go
