Windows 95 is a consumer-oriented graphical user interface-based operating system. An operating system (commonly abbreviated OS and O/S) is the software component of a Computer system that is responsible for the management and coordination It was released on August 24, 1995 by Microsoft,[2] and was a significant progression from the company's previous Windows products.

During development it was referred to as Windows 4. 0 or by the internal codename Chicago. Microsoft codenames are the Codenames given by Microsoft to products it has in development before these products are given the names by which they appear on store

Windows 95 was intended to integrate Microsoft's formerly separate MS-DOS and Windows products and includes an enhanced version of DOS, often referred to as MS-DOS 7. MS-DOS (short for M icro' s' oft D isk O perating S ystem is an Operating system commercialized by Microsoft. Microsoft Windows is a series of Software Operating systems and Graphical user interfaces produced by Microsoft. 0. It features significant improvements over its predecessor, Windows 3.1, most visibly the graphical user interface (GUI) whose basic format and structure is still used in later versions such as Windows Vista. Windows Vista (ˈvɪstə is a line of Operating systems developed by Microsoft for use on Personal computers including home and business desktops There were also large changes made to the underlying workings, including support for 255-character mixed-case long filenames and preemptively multitasked protected-mode 32-bit applications. Long filenames ( LFN) spelled "long file names" by Microsoft are longer and therefore more descriptive Filenames supported by the Microsoft Whereas its predecessors are optional "operating environments" requiring the MS-DOS operating system (usually available separately), Windows 95 is a consolidated operating system, which was a significant marketing change.

32-bit

Windows 95 followed Windows for Workgroups 3. Windows 31x was a major release of Microsoft Windows. Several editions were released between 1992 and 1994 succeeding Windows 3 11 with its lack of support for older, 16-bit x86 processors, thus requiring an Intel 80386 (or compatible) processor running in protected mode. See also X86 assembly language The generic term x86 refers to the most commercially successful Instruction set architecture in the history of Personal In computing protected mode, also called protected virtual address mode, is an operational mode of X86 -compatible Central processing units (CPU

Long file names

32-bit File Access is necessary for the long file names feature introduced with Windows 95 through the use of the VFAT file system. Microsoft Windows is a series of Software Operating systems and Graphical user interfaces produced by Microsoft. 32-bit file access refers to the higher performance Protected mode disk caching method introduced in Windows for Workgroups 3 Templateinfobox filesystem whilst covering all 3 file systems please make any style changes to both at the same time It is available to both Windows programs and MS-DOS programs started from Windows (they have to be adapted slightly, since accessing long file names requires using larger pathname buffers and hence different system calls). A path is the general form of a file or directory name giving a file's name and its unique location in a File system. In Computing, a buffer is a region of memory used to temporarily hold Data while it is being moved from one place to another In Computing, a system call is the mechanism used by an application program to request service from the Kernel. Competing DOS-compatible operating systems released before Windows 95 cannot see these names. Using older versions of DOS utilities to manipulate files means that the long names are not visible and are lost if files are moved or renamed, as well as by the copy (but not the original), if the file is copied. During a Windows 95 automatic upgrade of an older Windows 3. 1 system, DOS and third-party disk utilities which can destroy long file names are identified and made unavailable (Microsoft Anti-Virus for Windows indicated that the upgrade program was itself a computer virus). Microsoft Anti-Virus ( MSAV) was an antivirus program introduced by Microsoft for its A computer virus is a Computer program that can copy itself and infect a computer without permission or knowledge of the user When Windows 95 is started in DOS mode, e. g. for running DOS games, low-level access to disks is locked out. In case the need arises to depend on disk utilities that do not recognize long file names, such as MS-DOS 6. x's defrag utility, a program called LFNBACK for backup and restoration of long file names is provided on the CD-ROM. The program is in the \ADMIN\APPTOOLS\LFNBACK directory of the Windows 95 CD-ROM.

User interface

In the marketplace, Windows 95 was an unqualified success, and within a year or two of its release had become the most successful operating system ever produced. It also had the effect of driving other major players in the DOS-compatible operating system out of business, something which would later be used in court against Microsoft. DR-DOS is a DOS -type Operating system for IBM PC - compatible Personal computers, originally developed by Gary Kildall

Only the 4. x series of the browser contained the shell update, so those that wanted the new shell had to install IE4 with the desktop update before installing a newer version of Internet Explorer.

Windows 95 marked the introduction of the Start button and taskbar to Microsoft's GUI, both of which have remained fixtures of all subsequent versions of Windows, although the word "Start" was dropped from the button in Windows Vista, with the company preferring to label the button with the Windows logo ("Start" is still present as a tooltip and in the classic UI mode). In Computing, the taskbar is a term for an application desktop bar which is used to launch and monitor applications The tooltip is a common Graphical user interface element It is used in conjunction with a cursor, usually a mouse pointer

Prior to the official release, the American public was given a chance to preview Windows 95 in the Windows 95 Preview Program. For US$19. 95, users were sent a set of 3½" floppy diskettes that would install Windows 95 either as an upgrade to Windows 3. 1x or as a fresh install on a clean computer. Users who bought into the program were also given a free preview of The Microsoft Network (MSN), the online service that Microsoft was planning to launch with Windows 95, which allowed users to access the Internet and its services via PPP. MSN (The M icro' s' oft N etwork is a collection of Internet services provided by Microsoft.

Windows 95 was released with great fanfare, including a commercial featuring the Rolling Stones song "Start Me Up" (a reference to the Start button). " Start Me Up " is a song by The Rolling Stones featured on the 1981 album Tattoo You. [3] It was widely reported that Microsoft paid the Rolling Stones between $8 and $14 million for the use of the song (from the 1981 album Tattoo You) in the '95 advertising campaign. Microsoft Corporation is an American multinational Computer technology Corporation, which rose to dominate the Home computer Tattoo You is an album by The Rolling Stones, released in 1981 According to sources at Microsoft, however, this was just a rumor spread by the Stones to increase their market value, and Microsoft actually paid a fraction of that amount. [4] A 30 minute promotional video, labeled a "cyber sitcom", featuring Jennifer Aniston and Matthew Perry, was also released to showcase the features of Windows 95. Jennifer Joanna Aniston (born February 11 1969 is an American Film and television actress. Early life and education Perry was born in Williamstown Massachusetts. Microsoft's $3 million dollar advertising campaign featured stories of people waiting in line outside stores to get a copy.

Internet Explorer

Windows 95 originally shipped without Internet Explorer, and the default network installation did not install TCP/IP, the network protocol used on the Internet. At the release date of Windows 95, Internet Explorer 1. 0 was available, but only in the Plus! add-on pack for Windows 95, which was a separate product. The Plus! Pack did not reach as many consumers as the operating system itself (it was mainly advertised for its add-ons such as themes and better disk compression), and at the time of Windows 95 release, the web was being browsed mainly with a variety of early web browsers such as Netscape (promoted by products such as Internet in a Box). Internet in a Box ( IBox) was one of the first commercially available Internet connection software packages available for sale to the public

Microsoft Internet Explorer 4 (also IE4) is a graphical web browser released in September 1997 by Microsoft, primarily for Microsoft Windows, but also While Windows 95 was originally sold as a shrink-wrapped product, later editions were provided only to computer OEMs for installation on new PCs. An original equipment manufacturer, or OEM is typically a company that uses a component made by a second company in its own product or sells the product of the second company The term OEM Service Release is frequently abbreviated OSR, as in OSR1 or OSR2. 1. Thus, for example, OSR1 was the OEM release that was identical to Windows 95 retail with Service Pack 1 applied (with the addition of Internet Explorer). In order to maintain compatibility with existing programs, Windows 95 has an internal version number of "4. 00. 950", regardless of the internal build number, thus reflecting Windows 95's alternative identity as "Windows 4. 0" (similarly, the original edition of Windows 98 has an internal version number of Windows 4. Windows 98 ( codenamed Memphis) is a graphical Operating system released on 25 June 1998 by Microsoft and the successor to Windows 95 10. 1998. ) Later versions are sometimes referred to by the trailing letter appended to this version string, such as Windows 95 B for OSR2 and OSR2. 1.

System requirements

Official system requirements were an Intel 80386 DX CPU of any speed, 4 MB of system RAM, and 50 MB of hard drive space. These minimal claims were made in order to maximize the available market of Windows 3. 1 converts. This configuration was distinctly suboptimal for any productive use on anything but single tasking dedicated workstations due to the heavy reliance on virtual memory. Virtual memory is a Computer system technique which gives an application program the impression that it has contiguous working memory while in fact it may be physically Also, in some cases, if any networking or similar components were installed the system would refuse to boot with 4 megabytes of RAM. It was possible to run Windows 95 on a 386 SX but this led to even less acceptable performance due to its 16-bit external data bus. To achieve optimal performance, Microsoft recommends an Intel 80486 or compatible microprocessor with at least 8 MB of RAM. The Intel 486, otherwise known as the 80486 i486 or just 486 was the first tightly pipelined X86 design [8]

Windows 95 was superseded by Windows 98 and could still be directly upgraded by both Windows 2000[9] and Windows Me. Windows 98 ( codenamed Memphis) is a graphical Operating system released on 25 June 1998 by Microsoft and the successor to Windows 95 Windows 2000 (also referred to as Win2K) is a preemptive, interruptible graphical and business-oriented Operating system designed to work with Windows Millennium Edition, or Windows Me (IPA pronunciation, iː is a hybrid 16-bit / 32-bit graphical Operating system released on 14 September On December 31, 2001, Microsoft ended its support for Windows 95, making it an "obsolete" product according to the Microsoft Lifecycle Policy.

[10] Even though support for Windows 95 has ended, the software still remains in use on some home and school computers because of budget issues, a lack of knowledge or lack of desire to upgrade to newer editions of Windows. In addition, some video game enthusiasts choose to use Windows 95 for their legacy system to play old DOS games, although some other versions of Windows such as Windows 98 can also be used for this purpose.
