History of MIcrosoft

                                                                           The idea that would spawn Microsoft germinated when Paul Allen showed Bill Gates the January 1, 1975 issue of Popular Electronics that demonstrated the Altair 8800. Allen and Gates saw potential to develop an implementation of the programming language BASIC for the system.    Bill Gates called the creators of the new microcomputer, MITS() (Micro Instrumentation and Telemetry Systems), offering to demonstrate the implementation in order to win a contract with the company. Allen and Gates had neither an interpreter nor an Altair system, yet in the eight weeks before the demo they developed an interpreter. When Allen flew to Albuquerque, New Mexico to meet with MITS, the interpreter worked and MITS agreed to distributeAltair BASIC. Allen and Gates left Boston, where Allen worked for Honeywell and Gates was enrolled in Harvard, moved to Albuquerque (where MITS was located), and co-founded Microsoft there. Revenues of the company totaled $16,005 by the end of 1976.
               Allen came up with the original name of Micro-Soft (a portmanteau of microcomputer and software), as recounted in a 1995 Fortune magazine interview with Allen and Gates.Hyphenated in its early incarnations, on November 26, 1976 the company was registered under that name with the Secretary of State of New Mexico. The company's first international office was founded on November 1, 1978, in Japan, entitled "ASCII Microsoft" (now called "Microsoft Japan"), and on November 29, 1979, the term, "Microsoft" was first used by Bill Gates. On January 1, 1979, the company moved from Albuquerque to a new home in Bellevue, Washington. Steve Ballmer joined the company on June 11, 1980, and would later succeed Bill Gates as CEO. The company restructured on June 25, 1981, to become an incorporated business in its home state of Washington (with a further change of its name to "Microsoft, Inc."). As part of the restructuring, Bill Gates became president of the company and chairman of the board, and Paul Allen became Executive Vice President.
                     Microsoft's early products were different variants of Microsoft BASIC which was the dominant programming language in late 1970s and early 1980s home computers such as Apple II(Applesoft BASIC) and Commodore 64 (Commodore BASIC), and were also provided with early versions of the IBM PC as the IBM Cassette BASIC.
The first operating system publicly released by the company was a variant of Unix in 1980. Acquired from AT&T through a distribution license, Microsoft dubbed it Xenix, and hired Santa Cruz Operation in order to port/adapt the operating system to several platforms. This Unix variant would become home to the first version of Microsoft's word processor, Microsoft Word. Originally titled "Multi-Tool Word", Microsoft Word became notable for its concept of "What You See Is What You Get", or WYSIWYG.
                     Word was also the first application with such features as the ability to display bold text. It was first released in the spring of 1983, and free demonstration copies of the application were bundled with the November 1983 issue of PC World, making it the first program to be distributed on-disk with a magazine. However, Xenix was never sold to end users directly although it was licensed to many software OEMs for resale. It grew to become the most popular version of Unix, measured by the number of machines running it(note that Unix is a multi-user operating system, allowing simultaneous access to a machine by several users). By the mid-1980s Microsoft had gotten out of the Unix business, except for an interest in SCO.
                     DOS (Disk Operating System) was the operating system that brought the company its real success. International Business Machines (IBM) first approached Microsoft about its upcomingIBM Personal Computer (IBM PC) in July 1980. On August 12, 1981, after negotiations with Digital Research failed, IBM awarded a contract to Microsoft to provide a version of the CP/M operating system, which was set to be used in the IBM PC. For this deal, Microsoft purchased a CP/M clone called 86-DOS from Tim Paterson of Seattle Computer Products for less than US$100,000, which IBM renamed to PC DOS. Microsoft did not have an operating system when they closed the deal with IBM and IBM had not done their homework. Due to potential copyright infringement problems with CP/M, IBM marketed both CP/M and PC DOS for US$240 and US$40, respectively, with PC DOS eventually becoming the standard because of its lower price. 35 of the company's 100 employees worked on the IBM project for more than a year. When the IBM PC debuted, Microsoft was the only company that offered operating system, programming language, and application software for the new computer.
                   Around 1983, in collaboration with numerous companies, Microsoft created a home computer system, MSX, which contained its own version of the DOS operating system, entitled MSX-DOS; this became relatively popular in Japan, Europe and South America.Later, the market saw a flood of IBM PC clones after Columbia Data Products successfully cloned the IBM BIOS, quickly followed by Eagle Computer and Compaq.The deal with IBM allowed Microsoft to have control of its own QDOS derivative, MS-DOS, and through aggressive marketing of the operating system to manufacturers of IBM-PC clones Microsoft rose from a small player to one of the major software vendors in the home computer industry. With the release of the Microsoft Mouse on May 2, 1983, Microsoft continued to expand its product line in other markets. This expansion included Microsoft Press, a book publishing division, on July 11 the same year, which debuted with two titles: Exploring the IBM PCjr Home Computer by Peter Norton, and The Apple Macintosh Book by Cary Lu.

1985–1991:The rise and fall of OS/2

     Ireland became home to one of Microsoft's international production facilities in 1985, and on November 20 Microsoft released its first retail version of Microsoft Windows (Windows 1.0), originally a graphical extension for its MS-DOS operating system. In August, Microsoft and IBM partnered in the development of a different operating system called OS/2. OS/2 was marketed in connection with a new hardware design proprietary to IBM, the PS/2. On February 16, 1986, Microsoft relocated to Redmond, Washington. Around one month later, on March 13, the company went public with an IPO, raising US$61 million at US$21.00 per share. By the end of the trading day, the price had risen to US$28.00. In 1987, Microsoft eventually released their first version of OS/2 to OEMs.
          Meanwhile, Microsoft began introducing its most prominent office products. Microsoft Works, an integrated office program which combined features typically found in a word processorspreadsheetdatabaseand other office applications, saw its first release as an application for the Apple Macintosh towards the end of 1986. Microsoft Works would later be sold with other Microsoft products including Microsoft Word and Microsoft Bookshelf, a reference collection introduced in 1987 that was the company's first CD-ROM product. Later, on August 8, 1989, Microsoft would introduce its most successful office product, Microsoft Office. Unlike the model of Microsoft Works, Microsoft Office was a bundle of separate office productivity applications, such as Microsoft Word, Microsoft Excel and so forth. While Microsoft Word and Microsoft Office were mostly developed internally, Microsoft also continued its trend of rebranding products from other companies, such as Microsoft SQL Server on January 13, 1988, a relational database management system for companies that was based on technology licensed from Sybase.
                   On May 22, 1990 Microsoft launched Windows 3.0. The new version of Microsoft's operating system boasted such new features as streamlined graphic user interface GUI and improved protected modeability for the Intel 386 processor; it sold over 100,000 copies in two weeks. Windows at the time generated more revenue for Microsoft than OS/2, and the company decided to move more resources from OS/2 to Windows. In an internal memo to Microsoft employees on May 16, 1991, Bill Gates announced that the OS/2 partnership was over, and that Microsoft would henceforth focus its platform efforts on Windows and the Windows NT kernel. Some people, especially developers who had ignored Windows and committed most of their resources to OS/2, were taken by surprise, and accused Microsoft of deception. This changeover from OS/2 was frequently referred to in the industry as "the head-fake". In the ensuing years, the popularity of OS/2 declined, and Windows quickly became the favored PC platform. 1991 also marked the founding of Microsoft Research, an organization in Microsoft for researching computer science subjects, and Microsoft Visual Basic, a popular development product for companies and individuals.

1992–1995: Domination of the corporate market

                   During the transition from MS-DOS to Windows, the success of Microsoft's product Microsoft Office allowed the company to gain ground on application-software competitors, such as WordPerfect and Lotus 1-2-3. Novell, an owner of WordPerfect for a time, alleged that Microsoft used its inside knowledge of the DOS and Windows kernels and of undocumented Application Programming Interface features to make Office perform better than its competitors. Eventually, Microsoft Office became the dominant business suite, with a market share far exceeding that of its competitors. In March 1992, Microsoft released Windows 3.1 along with its first promotional campaign on TV; the software sold over three million copies in its first two months on the market.In October, Windows for Workgroups 3.1 was released with integrated networking abilities such as peer-to-peer file and printing sharing. In November, Microsoft released the first version of their popular database software Microsoft Access.

                 By 1993, Windows had become the most widely used GUI operating system in the world. Fortune Magazine named Microsoft as the "1993 Most Innovative Company Operating in the U.S." The year also marked the end of a five-year copyright infringement legal case brought by Apple Computer, dubbed Apple Computer, Inc. v. Microsoft Corp., in which the ruling was in Microsoft's favor, the release of Windows for Workgroups 3.11, a new version of the consumer line of Windows, and Windows NT 3.1, a server-based operating system with a similar user interface to consumer versions of the operating system, but with an entirely different kernel. As part of its strategy to broaden its business, Microsoft released Microsoft Encarta on March 22, 1993, the first encyclopedia designed to run on a computer. Soon after, the Microsoft Home brand was introduced – encompassing Microsoft's new multimedia applications for Windows 3.x., Microsoft changed its slogan to "Where do you want to go today?" in 1994 as part of an attempt to appeal to nontechnical audiences in a US$100 million advertising campaign.
           Microsoft continued to make strategic decisions directed at consumers. The company released Microsoft Bob, a graphical user interface designed for novice computer users, in March 1995. The interface was discontinued in 1996 due to poor sales; Bill Gates later attributed its failure to hardware requirements that were too high for typical computers; Microsoft Bob is widely regarded as Microsoft's most unsuccessful product. DreamWorks SKG and Microsoft formed a new company, DreamWorks Interactive (in 2000 acquired by Electronic Arts which named it EA Los Angeles), to produce interactive and multimedia entertainment properties. On August 24, 1995, Microsoft released Microsoft Windows 95, a new version of the company's flagship operating system which featured a completely new user interface, including a novel start button; more than a million copies of Microsoft Windows 95 were sold in the first four days after its release.
Windows 95 was released without a web browser as Microsoft had not yet developed one. The success of the Internet caught them by surprise and they subsequently approached Spyglass to license their browser as Internet Explorer. Spyglass went on to later dispute the terms of the agreement, as Microsoft was to pay a royalty for every copy sold. However, Microsoft sold no copies of Internet Explorer, choosing instead to bundle it for free with the operating system.
Internet Explorer was first included in the Windows 95 Plus! Pack that was released in August 1995. In September, the Chinese government chose Windows to be the operating system of choice in that country, and entered into an agreement with the Company to standardize a Chinese version of the operating system.Microsoft also released the Microsoft Sidewinder 3D Pro joystick in an attempt to further expand its profile in the computer hardware market.

1995–1999: Foray into the Web and other ventures

                    On, May 26, 1995, Bill Gates sent the "Internet Tidal Wave" memorandum to Microsoft executives. The memo described Netscape with their Netscape Navigator as a "new competitor 'born' on the Internet." The memo outlines Microsoft's failure to grasp the Internet's importance, and in it Gates assigns "the Internet this highest level of importance" from then on. Microsoft began to expand its product line into computer networking and the World Wide Web. On August 24, 1995, it launched a major online serviceMSN (Microsoft Network), as a direct competitor to AOL. MSN became an umbrella service for Microsoft's online services, using Microsoft Passport (now called Windows Live ID) as a universal login system for all of its web sites. The company continued to branch out into new markets in 1996, starting with a joint venture with NBC to create a new 24-hour cable news television station, MSNBC. The station was launched on July 15, 1996 to compete with similar news outlets such as CNN. Microsoft also launched Slate, an online magazine edited by Michael Kinsley, which offered political and social commentary along with the cartoon Doonesbury. In an attempt to extend its reach in the consumer market, the company acquired WebTV, which enabled consumers to access the Web from their televisions. Microsoft entered the personal digital assistant (PDA) market in November with Windows CE 1.0, a new built-from-scratch version of their flagship operating system, designed to run on low-memory, low-performance machines, such as handhelds and other small computers. 1996 saw the release of Windows NT 4.0, which brought the Windows 95 GUI and Windows NT kernel together.
                While Microsoft largely failed to participate in the rise of the Internet in the early 1990s, some of the key technologies in which the company had invested to enter the Internet market started to pay off by the mid-90s. One of the most prominent of these was ActiveX, an application programming interface built on the Microsoft Component Object Model (COM); this enabled Microsoft and others to embed controls in many programming languages, including the company's own scripting languages, such as JScript and VBScript. ActiveX included frameworks for documents and server solutions. The company also released the Microsoft SQL Server 6.5, which had built-in support for internet applications. Later in 1997, Microsoft Office 97 as well as Internet Explorer 4.0 were released, marking the beginning of the takeover of the browser market from rival Netscape, and by agreement with Apple Computer, Internet Explorer was bundled with the Apple Macintosh operating system as well as with Windows. Windows CE 2.0, the handheld version of Windows, was released this year, including a host of bug fixes and new features designed to make it more appealing to corporate customers. In October, the Justice Department filed a motion in the federal district court in which they stated that Microsoft had violated an agreement signed in 1994, and asked the court to stop the bundling of Internet Explorer with Windows.
Windows 98 desktop
                    The year 1998 was significant in Microsoft's history, with Bill Gates appointing Steve Ballmer as president of Microsoft but remaining as Chair and CEO himself. The company released an update to the consumer version of Windows, Windows 98. Windows 98 came with Internet Explorer 4.0 SP1 (which had Windows Desktop Update bundled), and included new features from Windows 95 OSR 2.x including the FAT32 file system, and new features designed for Windows 98, such as support for multiple displays. Microsoft launched its Indian headquarters as well, which would eventually become the company's second largest after its U.S. headquarters. Finally, a great deal of controversy took place when a set of internal memos from the company were leaked on the Internet. These documents, colloquially referred to as "The Halloween Documents", were widely reported by the media and go into detail of the threats that free software / open source software poses to Microsoft's own software, previously voiced mainly by analysts and advocates of open source software. The documents also allude to legal and other actions against Linux as well as other open source software. While Microsoft acknowledges the documents, it claims that they are merely engineering studies. Despite this, some believe that these studies were used in the real strategies of the company.

2000–2005: Legal issues, XP, and .NET

              Microsoft, in 2000, released new products for all three lines of the company's flagship operating system, and saw the beginning of the end of one of its most prominent legal cases. On February 17, 2000, Microsoft released an update to its business line of software in Windows 2000. It provided a high level of stability similar to that of its Unix counterparts due to its usage of the Windows NT kernel, and matching features found in the consumer line of the Windows operating system including a DOS emulator that could run many legacy DOS applications.
             On April 3, 2000, a judgment was handed down in the case of United States v. Microsoft, calling the company an "abusive monopoly" and forcing the company to split into two separate units. Part of this ruling was later overturned by a federal appeals court, and eventually settled with the U.S. Department of Justice in 2001. On June 15, 2000, the company released a new version of its hand-held operating system, Windows CE 3.0. The main change was the new programming APIs of the software. Previous versions of Windows CE supported only a small subset of the WinAPI, the main development library for Windows, and with Version 3 of Windows CE, the operating system now supported nearly all of the core functionality of the WinAPI. The next update to the consumer line, Windows Me(or Windows Millennium Edition), was released on September 14, 2000.It sported several new features such as enhanced multimedia abilities and consumer-oriented PC maintenance options, but is often regarded as one of the worst versions of Windows due to installation problems and other issues.
Windows XP introduced a new interface, along with many other new features. This screenshot shows Windows XP Professional.
         Microsoft released Windows XP and Office XP in 2001, a version that aimed to encompass the features of both its business and home product lines. The release included an updated version of the Windows 2000 kernel, enhanced DOS emulation abilities, and many of the home-user features found in previous consumer versions. XP introduced a new graphical user interface, the first such change since Windows 95. The operating system was the first to require Microsoft Product Activation, an anti-piracy mechanism that requires users to activate the software with Microsoft within 30 days. Later, Microsoft would enter the multi-billion-dollar game console market dominated by Sony and Nintendo, with the release of the Xbox. The Xbox finished behind the dominantPlayStation 2 selling 24 million units compared to the PlayStation 2's 136 million however they managed to outsell the Nintendo Gamecube which sold 21 million units. Microsoft launched their second console, the Xbox 360, in 2005 – which has turned out to be a lot more successful than their first console. It has sold 40 million units as of 2010 and it has outsold Sony's PlayStation 3 which has so far sold 35 million units. However, despite beating Sony with their last Xbox console, Microsoft so far has been outsold by the Nintendo Wii which introduced gesture control and opened up a new market for video games. Microsoft later used their popular controller-free Kinect peripheral to increase the popularity of the Xbox. This was very successful. As of 2011 Kinect was the fastest selling consumer electronics product in history. It sold 8 million units from November 4, 2010 to January 3, 2011 (its first 60 days). It averaged 133,333 units per day, outselling the iPhone and iPad over equivalent post-launch periods.
                  In 2002, Microsoft launched the .NET initiative, along with new versions of some of its development products, such as Microsoft Visual Studio. The initiative has been an entirely new development API for Windows programming, and includes a new programming language, C#Windows Server 2003 was launched, featuring enhanced administration abilities, such as new user interfaces to server tools. In 2004, the company released Windows XP Media Center Edition 2005, a version of Windows XP designed for multimedia abilities, and Windows XP Starter Edition, a version of Windows XP with a smaller feature set designed for entry-level consumers. However, Microsoft would encounter more turmoil in March 2004 when antitrust legal action would be brought against it by the European Union for allegedly abusing its market dominance (see European Union Microsoft antitrust case). Eventually Microsoft was fined €497 million (US$613 million), ordered to divulge certain protocols to competitors, and to produce a new version of its Windows XP platform—called Windows XP Home Edition N—that did not include its Windows Media Player. Microsoft was also ordered to produce separate packages of Windows after South Korea also landed a settlement against the company in 2005. It had to pay out US$32 million and produce more than one version of Windows for the country in the same vein as the European Union-one with Windows Media Player and Windows Messenger and one without the two programs.

2005–present: Vista, Windows 7 and Windows 8

            In guise of competing with other Internet companies such as the search service Google, in 2005 Microsoft announced a new version of its MSN search service. Later, in 2006, the company launched Microsoft adCenter, a service that offers pay per click advertisements, in an effort to further develop their search marketing revenue.Soon afterward, Microsoft created the CodePlex collaborative development site for hosting open source projects. Activity grew quickly as developers from around the world began to participate, and by early 2007 commercial open source companies, such as Aras Corp,. began to offer enterprise open source software exclusively on the Microsoft platform.
                 On June 15, 2006 Bill Gates announced his plans for a two-year transition period out of a day-to-day role with Microsoft until July 31, 2008. After that date, Gates will continue in his role as the company's chairman, head of the board of directors and act as an adviser on key projects. His role as Chief Software Architect will be filled immediately by Ray Ozzie, the Chief Technical Officer of the company as of June 15, 2006. Bill Gates stated "My announcement is not a retirement – it’s a reordering of my priorities."
                     Formerly codenamed "Longhorn" in the early development stages, Windows Vista was released to consumers on January 30, 2007. Microsoft also released a new version of its Office suite, called Microsoft Office 2007, alongside Windows Vista.Windows Server 2008 and Visual Studio 2008, the next versions of the company's server operating system and development suite, respectively, were released on February 27, 2008. Windows Vista was criticized for being heavy and needing large amounts of power to run the desktop widgets and the Aero theme. Many people continued to use Windows XP for many years after, due to its stability and low processing needs.
                   On December 19, 2007, Microsoft signed a five-year, $500 million contract with Viacom that included content sharing and advertisements. The deal allowed Microsoft to license many shows from Viacom owned cable television and film studios for use on Xbox Live and MSN. The deal also made Viacom a preferred publisher partner for casual game development and distribution through MSN and Windows. On the advertisement side of the deal, Microsoft's Atlas ad-serving division became the exclusive provider of previously unsold advertising inventory on Viacom owned web sites. Microsoft also purchased a large amount of advertising on Viacom owned broadcasts and online networks, and collaborated on promotions and sponsorships for MTV and BET award shows, two Viacom owned cable networks.
                In 2008, Microsoft wanted to purchase Yahoo (first completely, later partially) in order to strengthen its position on the search engine market vis-à-vis Google. The company rejected the offer, saying that it undervalued the company. In response, Microsoft withdrew its offer.
              In 2009, the opening show of the Consumer Electronics Show (CES) was hosted by Steve Ballmer for the first time. In past years, it has been hosted by Bill Gates. In the show, Ballmer announced the first public Beta Test of Windows 7 for partners and developers on January 8, but also for the general public on January 10.
On June 26, 2009 Microsoft started taking pre-orders at a discounted price for Windows 7 which was launched on October 22, 2009. Windows 7 has several editions, which acknowledge the rise of netbook computers with reduced processing power.
On May 10, 2011, Microsoft Corp. acquired Skype Communications, S.à r.l for US $8.5 billion.
On August 23, 2012, Microsoft unveiled a new corporate logo at the opening of its 23rd Microsoft store in Boston indicating the company's shift of focus from the classic style to the tile-centric Modern interface which is used on the Windows Phone, Xbox 360 and Windows 8 platforms.
The new logo also includes four squares with the colors (red, green, blue, and yellow) of the then-current Windows logo, and it incorporates the company's Segoe font.
On January 31, 2013, I/P Engine filed a lawsuit against Microsoft for search related patents.
On April 8, 2013, Microsoft sold its IPTV business (Mediaroom) to Ericsson.
On July 12, 2013, Microsoft is suing the U.S. Customs and Border Protection over Google phone ban. Homeland Security Secretary Janet Napolitano is also named in the lawsuit.

computer network


 A computer network (or data network) is a telecommunications network that allows computers to exchange data. The physical connection between networked computing devices is established using either cable media or wireless media. The best-known computer network is the Internet.

History

Before the advent of computer networks, communication between calculation machines and early computers was performed by human users by carrying instructions between them. Today, in spite of the wide use of email and other networking applications, people do continue to transfer information to another person's computer by hand-carrying removable storage media (such as flash drives) — a method jokingly known as "sneakernet".
                Today, computer networks are the core of modern communication. All modern aspects of the public switched telephone network (PSTN) are computer-controlled. Telephony increasingly runs over the Internet Protocol, although not necessarily the public Internet. The scope of communication has increased significantly in the past decade. This boom in communications would not have been possible without the progressively advancing computer network. Computer networks, and the technologies that make communication between networked computers possible, continue to drive computer hardware, software, and peripherals industries. The expansion of related industries is mirrored by growth in the numbers and types of people using networks, from the researcher to the home user. 
Type of network

 Local area network (LAN)

                   - is a small computer network that usually using in short connection.
                   - Connection in same or near area.
                   - Connection from 2 computers and tools or more.
                   - If want far connection, must use repeater together.

      Metropolitan area network

                   - is a large computer network or aggregation of LAN.
                   - Cover wide areas in citys.
                   -  must use Backbone which serves as a connection main line.

      Wide area network

                    - is a computer network that covers a large geographic area.
                    - uses a communications channel that combines many types of media such as telephone lines, cables, and air waves.

Network topology


              Network topology is the layout or organizational hierarchy of interconnected nodes of a computer network.
  • bus network: all nodes are connected to a common medium along this medium. This was the layout used in the original Ethernet, called 10BASE5and 10BASE2.
  • star network: all nodes are connected to a special central node. This is the typical layout found in a Wireless LAN, where each wireless client connects to the central Wireless access point.
  • ring network: each node is connected to its left and right neighbour node, such that all nodes are connected and that each node can reach each other node by traversing nodes left- or rightwards. The Fiber Distributed Data Interface (FDDI) made use of such a topology.
  • mesh network: each node is connected to an arbitrary number of neighbours in such a way that there is at least one traversal from any node to any other.
  • A fully connected network: each node is connected to every other node in the network.
