setelah UTS Pengantar Broadcast yang kuduga NGGAK AKAN BISA, tapi alhamdulillah kelar dengan optimis.
dari kemarin si :) ngajak ketemuan, tapi bisanya di hari itu --> Selasa, 26 Oktober 2010
taunyaaaaaaaa..

di pinggir ladang yang gak ada bangunan dengan rerumputan liar (dekat jembatan), aq nungguin :) di situ karena instruksinya.
terus aq tunggu sambil duduk di motorku.
eh gak lama kemudian, dia nongol dari belakang sambil bilang, "ngojek, mbak?!" jujur aq langsung deg-degan.

setelah ituuuu..
:) ngajak duduk di pinggir ladang, alias di sisi jembatan depan rumput liar itu. Tapi aku pura-pura nggak denger dan tetep duduk di motor, tapi turun menyimpang.

hapalnya aku lupaaa..
tapi dia tiba-tiba bilang satu kalimat yang aku tunggu dari dulu.
SEERRRRR.. tiba-tiba gitu aja aku kaget dengernya. spontan aku ketawa ngakak gatau kenapa. *aku gak pernah dan gak mau jaim soalnya di depan :)*

dia bilang kayak lagunya Super Junior - U --> coz I can't stop thinking about you..." WADUH !! aku langsung kepikiran itu LAGU SUJU !
hahaha

lama aku ketawa dan mengumpulkan semua kesadaranku bahwa ITU SEMUA NGGAK MIMPI !
and the last.. aku ngangguk" aja pas :) nanya "kamu gimana?"
wahahahahaha

and next, aku bilang ke dia kalo this is my first time that happened in my life. :) juga bilang gitu..
xixixixi

yap, aku gak mau munafik. aku gak suka pacaran kayak orang lain yang berduaan, terus pegang-pegangan. I HATE THAT SITUATION BECAUSE I'M MOESLEM !
hihiy

:) pengertian kok.. dia ngerti.
terus jadinya kita sepakat komunikasi harus tetap jalan, sambil mengaitkan kelingking kita.
ahhh neomu kyeopta !!
kkkkkkk~

dan karena esoknya aku masih ada UTS terakhir MANAJEMEN PEMASARAN yang akhirnya sukses keesokan harinya, aku harus cepat pulang untuk melanjutkan belajar. Tapi ngenet dulu sih.. hahaha

:) juga mau UTS jam 3, jadi kita byebye dulu.

hihiy
gak pacaran, itu target hidupku. hanya saling mengungkapkan.. ^^

aku perkirakan sekitar pukul 14:41

nice day !

FIFO and LIFO accounting

2009-10-06T13:45:00.001+07:00

From Wikipedia, the free encyclopedia
FIFO and LIFO accounting Methods are means of managing inventory and financial matters involving the money a company ties up within inventory of produced goods, raw materials, parts, components, or feed stocks. FIFO stands for first-in, first-out, meaning that the oldest inventory items are recorded as sold first. LIFO stands for last-in, first-out, meaning that the most recently purchased items are recorded as sold first. Since the 1970s, U.S. companies have tended to use LIFO, which reduces their income taxes in times of inflation.

LIFO accounting
LIFO is an acronym for "last in, first out." (Sometimes the term FILO ("first in, last out") is used synonymously.) In LIFO accounting, a historical method of recording the value of inventory, a firm records the last units purchased as the first units sold. LIFO accounting is in contrast to the method FIFO accounting covered below.
Since prices generally rise over time because of inflation, this method records the sale of the most expensive inventory first and thereby decreases profit and reduces taxes. However, this method rarely reflects the physical flow of indistinguishable items.
LIFO valuation is permitted in the belief that an ongoing business does not realize an economic profit solely from inflation. When prices are increasing, they must replace inventory currently being sold with higher priced goods. LIFO better matches current cost against current revenue. It also defers paying taxes on phantom income arising solely from inflation. LIFO is attractive to business in that it delays a major detrimental effect of inflation, namely higher taxes. However, in a very long run, both methods converge.
“Last in first out” (LIFO) is not acceptable in the IFRS.
FIFO accounting
FIFO accounting is a common method for recording the value of inventory. It is appropriate where there are many different batches of similar products. The method presumes that the next item to be shipped will be the oldest of that type in the warehouse. In practice, this usually reflects the underlying commercial substance of the transaction, since many companies rotate their inventory (especially of perishable goods). This is still not in contrast to LIFO because FIFO and LIFO are cost flow assumptions not product flow assumptions.
LIFO is based on an irrational assumption that inventories entering last in stores are issued/consumed first.
In an economy of rising prices (during inflation), it is common for beginning companies to use FIFO for reporting the value of merchandise to bolster their balance sheet. As the older and cheaper goods are sold, the newer and more expensive goods remain as assets on the company's books. Having the higher valued inventory and the lower cost of goods sold on the company's financial statements may increase the chances of getting a loan. However, as it prospers the company may switch to LIFO to reduce the amount of taxes it pays to the government.
LIFO liquidation
Notwithstanding its deferred tax advantage, a LIFO inventory system can lead to LIFO liquidation, a situation where in the absence of new replacement inventory or a search for increased profits, older inventory is increasingly liquidated (or sold). If prices have been rising, for example through inflation, this older inventory will have a lower cost, and its liquidation will lead to the recognition of higher net income and the payment of higher taxes, thus reversing the deferred tax advantage that initially encouraged the adoption of a LIFO system. Some companies who use LIFO have decades-old inventory recorded on their books at a very low cost. For these companies a LIFO liquidation would result in an inflated net income and higher tax payments. This situation is usually undesirable; on rare occasions a company in financial stress could abuse this method to temporarily increase income.

• Average costing
[edit] Example of FIFO vs LIFO accounting
Suppose we have to value 120 items of our stock today (June 2009), and that they were purchased at 3 different dates and 3 different prices:
Date Quantity Unitary Price (USD)
March 2009 50 10
April 2009 55 11
May 2009 15 12
The FIFO price starts with the oldest one. Since we have to calculate 120 items, we consider that the first 50 have a unitary value of 10 USD, (the oldest price); the next 55 will have a unitary value of 11 USD, and the remaining 15 (120-50-55) will have a unitary value of 12 USD.

Therefore, the FIFO price is 10.71 USD:

The LIFO price starts with the most recent one. Since we have to calculate 120 items, we consider that the first 52 have a unitary value of 12 USD, (the most recent price); the next 55 will have a unitary value of 11 USD, and the remaining 13 (120-52-55) will have a unitary value of 10 USD.

Therefore, the LIFO price is 11.33 USD:

As we can see, in normal economic conditions (i.e. in presence of inflation) the LIFO price is bigger than the FIFO. Indeed, the FIFO price undervalues the price of the liabilities (the 120 items in the example), and since these are smaller the FIFO price overvalues the remaining stock. On the contrary, the LIFO price undervalues the current stock because it overprices the liabilities.

FIFO (computing)

2009-10-06T13:41:00.001+07:00

From Wikipedia, the free encyclopedia

Jump to: navigation, search

This article is about FIFOs in computing and electronic design. For the term in accounting, see FIFO and LIFO accounting.

FIFO is an acronym for First In, First Out, an abstraction in ways of organizing and manipulation of data relative to time and prioritization. This expression describes the principle of a queue processing technique or servicing conflicting demands by ordering process by first-come, first-served (FCFS) behaviour: what comes in first is handled first, what comes in next waits until the first is finished, etc.

Thus it is analogous to the behaviour of persons queueing (or "standing in line", in common American parlance), where the persons leave the queue in the order they arrive, or waiting one's turn at a traffic control signal. FCFS is also the shorthand name (see Jargon and acronym) for the FIFO operating system scheduling algorithm, which gives every process CPU time in the order they come. In the broader sense, the abstraction LIFO, or Last-In-First-Out is the opposite of the abstraction FIFO organization, the difference perhaps is clearest with considering the less commonly used synonym of LIFO, FILO—meaning First-In-Last-Out. In essence, both are specific cases of a more generalized list (which could be accessed anywhere). The difference is not in the list (data), but in the rules for accessing the content. One sub-type adds to one end, and takes off from the other, its opposite takes and puts things only on one end.^[1]

A priority queue is a variation on the queue which does not qualify for the name FIFO, because it is not accurately descriptive of that data structure's behavior. Queueing theory encompasses the more general concept of queue, as well as interactions between strict-FIFO queues.

Computer science

Data structure

In computer science this term refers to the way data stored in a queue is processed. Each item in the queue is stored in a queue (simpliciter) data structure. The first data to be added to the queue will be the first data to be removed, then processing proceeds sequentially in the same order. This is typical behavior for a queue, but see also the LIFO and stack algorithms.

A typical data structure will look like

struct fifo_node

  struct fifo_node *next;

  value_type value;

};

class fifo

  fifo_node *front;

  fifo_node *back;

  fifo_node *dequeue(void)

    fifo_node *tmp = front;

    front = front->next;

    return tmp;

  queue(value)

    fifo_node *tempNode = new fifo_node;

    tempNode->value = value;

    back->next = tempNode;

    back = tempNode;

};

(For information on the abstract data structure, see Queue. For details of a common implementation, see Circular buffer.)

Popular Unix systems include a sys/queue.h C/C++ header file which provides macros usable by applications which need to create FIFO queues.

] Head or tail first

Authors and users of FIFO queue software should consider carefully the use of the terms "head" and "tail" to refer to the two ends of the queue. To many people, items should enter a queue at the tail, remain in the queue until they reach the head and leave the queue from there. This point of view is justified by analogy with queues of people waiting for some kind of service and parallels the use of "front" and "back" in the above example. Other people, however, believe that you enter a queue at the head and leave at the tail, in the manner of food passing through a snake. Queues written in that way appear in places that might be considered authoritative, such as the GNU/Linux operating system.

Pipes

In computing environments that support the pipes and filters model for interprocess communication, a FIFO is another name for a named pipe.

Disk Scheduling

Disk controllers can use the FIFO as a disk scheduling algorithm to determine the order to service disk I/O requests.

Communications and networking

Communications bridges, switches and routers used in Computer networks use FIFOs to hold data packets in route to their next destination. Typically at least one FIFO structure is used per network connection. Some devices feature multiple FIFOs for simultaneously and independently queuing different types of information.

Electronics

FIFOs are used commonly in electronic circuits for buffering and flow control which is from hardware to software. In hardware form a FIFO primarily consists of a set of read and write pointers, storage and control logic. Storage may be SRAM, flip-flops, latches or any other suitable form of storage. For FIFOs of non-trivial size a dual-port SRAM is usually used where one port is used for writing and the other is used for reading.

A synchronous FIFO is a FIFO where the same clock is used for both reading and writing. An asynchronous FIFO uses different clocks for reading and writing. Asynchronous FIFOs introduce metastability issues. A common implementation of an asynchronous FIFO uses a Gray code (or any unit distance code) for the read and write pointers to ensure reliable flag generation. One further note concerning flag generation is that one must necessarily use pointer arithmetic to generate flags for asynchronous FIFO implementations. Conversely, one may use either a "leaky bucket" approach or pointer arithmetic to generate flags in synchronous FIFO implementations.

Examples of FIFO status flags include: full, empty, almost full, almost empty, etc...

The first known FIFO implemented in electronics was done by Peter Alfke in 1969 at Fairchild Semiconductors. Peter Alfke is now a Director at Xilinx.

FIFO full/empty

In hardware FIFO is used for synchronization purposes. It is often implemented as a circular queue, and thus has two pointers:

Read Pointer/Read Address Register
Write Pointer/Write Address Register

Read and write addresses are initially both at the first memory location and the FIFO queue is Empty.

FIFO Empty

When read address register reaches to write address register, the FIFO triggers the Empty signal.

FIFO FULL

When write address register reaches to read address register, the FIFO triggers the FULL signal.

Microsoft Windows is a series of software operating systems and graphical user interfaces produced by Microsoft. Microsoft first introduced an operating environment named Windows in November 1985 as an add-on to MS-DOS in response to the growing interest in graphical user interfaces (GUIs).^[1] Microsoft Windows came to dominate the world's personal computer market, overtaking Mac OS, which had been introduced previously. As of July 2009, Windows had approximately 93% of the market share of the client operating systems for usage on the Internet.^[2] The most recent client version of Windows is Windows Vista; the most recent server version is Windows Server 2008. Vista's successor, Windows 7 (currently at release to manufacturing), is scheduled to be released on October 22, 2009.

Versions

The term Windows collectively describes any or all of several generations of Microsoft operating system products. These products are generally categorized as follows:

Early versions

Main articles: Windows 1.0, Windows 2.0, and Windows 2.1x

The history of Windows dates back to September 1981, when the project named "Interface Manager" was started. It was announced in November 1983 (after the Apple Lisa, but before the Macintosh) under the name "Windows", but Windows 1.0 was not released until November 1985.^[3] The shell of Windows 1.0 was a program known as the MS-DOS Executive. Other supplied programs are Calculator, Calendar, Cardfile, Clipboard viewer, Clock, Control Panel, Notepad, Paint, Reversi, Terminal, and Write. Windows 1.0 does not allow overlapping windows, due to Apple Computer owning this feature^{[citation needed]}. Instead all windows are tiled. Only dialog boxes can appear over other windows.

Windows 2.0 was released in October 1987 and featured several improvements to the user interface and memory management.^[3] Windows 2.0 allowed application windows to overlap each other and also introduced more sophisticated keyboard-shortcuts. It could also make use of expanded memory.

Windows 2.1 was released in two different flavors: Windows/386 employed the 386 virtual 8086 mode to multitask several DOS programs, and the paged memory model to emulate expanded memory using available extended memory. Windows/286 (which, despite its name, would run on the 8086) still ran in real mode, but could make use of the high memory area.

The early versions of Windows were often thought of as simply graphical user interfaces, mostly because they ran on top of MS-DOS and used it for file system services.^[4] However, even the earliest 16-bit Windows versions already assumed many typical operating system functions; notably, having their own executable file format and providing their own device drivers (timer, graphics, printer, mouse, keyboard and sound) for applications. Unlike MS-DOS, Windows allowed users to execute multiple graphical applications at the same time, through cooperative multitasking. Windows implemented an elaborate, segment-based, software virtual memory scheme, which allowed it to run applications larger than available memory: code segments and resources were swapped in and thrown away when memory became scarce, and data segments moved in memory when a given application had relinquished processor control, typically waiting for user input.^{[citation needed]}

Windows 3.0 and 3.1

Main articles: Windows 3.0 and Windows 3.1x

Windows 3.0 (1990) and Windows 3.1 (1992) improved the design, mostly because of virtual memory and loadable virtual device drivers (VxDs) which allowed them to share arbitrary devices between multitasked DOS windows.^{[citation needed]} Also, Windows applications could now run in protected mode (when Windows was running in Standard or 386 Enhanced Mode), which gave them access to several megabytes of memory and removed the obligation to participate in the software virtual memory scheme. They still ran inside the same address space, where the segmented memory provided a degree of protection, and multi-tasked cooperatively. For Windows 3.0, Microsoft also rewrote critical operations from C into assembly, making this release faster and less memory-hungry than its predecessors.^{[citation needed]} With the introduction of the Windows for Workgroups 3.11, Windows was able to bypass DOS for file management operations using 32-bit file access.^{[citation needed]}

Windows 95, 98, and Me

Main articles: Windows 95, Windows 98, and Windows Me

Windows 95 was released in 1995, featuring a new user interface, supported long file names of up to 250 characters, could automatically detect and configure installed hardware (plug and play), natively ran 32-bit applications, and featured several technological improvements that increased its stability over Windows 3.1. Windows 95 uses pre-emptive multitasking and runs each 32-bit application in a separate address space. This makes it harder for a single buggy application to crash the whole system. It was still not a secure multi-user operating system like Windows NT as a strict separation between applications was not enforced by the kernel. The API was a subset of the Win32 API supported by Windows NT, notably lacking support for Unicode and functions related to security. Windows 95 was now bundled together with MS-DOS 7.0, however its role was mostly delegated to that of a boot loader.

There were several releases of Windows 95; the first in 1995, with Service Pack 1 following in December which included Internet Explorer 2.0. Subsequent versions were only available with the purchase of a new computer and were called OEM Service Releases. OSR1 was equivalent to Windows 95 with SP1. OSR2 (also called Windows 95 B) included support for FAT32 and UDMA and shipped with Internet Explorer 3. OSR 2.1 included basic support for USB and OSR 2.5 (also called Windows 95C) shipped with Internet Explorer 4.0.

Microsoft's next release was Windows 98 in 1998. Microsoft released a second version of Windows 98 in 1999, named Windows 98 Second Edition (often shortened to Windows 98 SE).

In 2000, Microsoft released Windows Me (Me standing for Millennium Edition), which used the same core as Windows 98 but adopted some aspects of Windows 2000 and removed the "boot in DOS mode" option. It also added a new feature called System Restore, allowing the user to set the computer's settings back to an earlier date.

Windows NT family

Main article: Windows NT

The NT family of Windows systems was fashioned and marketed for higher reliability business use. The first release was MS Windows NT 3.1 (1993), numbered "3.1" to match the consumer Windows version, which was followed by NT 3.5 (1994), NT 3.51 (1995), NT 4.0 (1996), and Windows 2000 (2000). 2000 is the last NT-based Windows release which does not include Microsoft Product Activation. NT 4.0 was the first in this line to implement the "Windows 95" user interface (and the first to include Windows 95’s built-in 32-bit runtimes). Microsoft then moved to combine their consumer and business operating systems with Windows XP, coming in both home and professional versions (and later niche market versions for tablet PCs and media centers); they also diverged release schedules for server operating systems. Windows Server 2003, released a year and a half after Windows XP, brought Windows Server up to date with MS Windows XP. After a lengthy development process, Windows Vista was released toward the end of 2006, and its server counterpart, Windows Server 2008 was released in early 2008. On July 22, 2009, Windows 7 and Windows Server 2008 R2 were released as RTM (release to manufacturing). Microsoft plans to release Windows 7 in late October 2009.

Windows CE, Microsoft’s offering in the mobile and embedded markets, is also a true 32-bit operating system that offers various services for all sub-operating workstations.

64-bit operating systems

Windows NT included support for several different platforms before the x86-based personal computer became dominant in the professional world. Versions of NT from 3.1 to 4.0 variously supported PowerPC, DEC Alpha and MIPS R4000, some of which were 64-bit processors, although the operating system treated them as 32-bit processors.

With the introduction of the Intel Itanium architecture, which is referred to as IA-64, Microsoft released new versions of Windows to support it. Itanium versions of Windows XP and Windows Server 2003 were released at the same time as their mainstream x86 (32-bit) counterparts. On April 25, 2005, Microsoft released Windows XP Professional x64 Edition and x64 versions of Windows Server 2003 to support the x86-64 (or x64 in Microsoft terminology) architecture. Microsoft dropped support for the Itanium version of Windows XP in 2005. Windows Vista is the first end-user version of Windows that Microsoft has released simultaneously in x86 and x64 editions. Windows Vista does not support the Itanium architecture. The modern 64-bit Windows family comprises AMD64/Intel64 versions of Windows Vista, and Windows Server 2008, in both Itanium and x64 editions. Windows Server 2008 R2 drops the 32-bit version, although Windows 7 does not.

Windows CE

Main article: Windows CE

Windows CE (officially known as Windows Embedded), is an edition of Windows that runs on minimalistic computers, like satellite navigation systems, and uncommonly mobile phones. Windows Embedded runs as CE, rather than NT, which is why it should not be mistaken for Windows XP Embedded, which is NT. Windows CE was used in the Sega Dreamcast along with Sega's own proprietary OS for the console.

History

Main article: History of Microsoft Windows

The Windows family tree.

Microsoft has taken two parallel routes in its operating systems. One route has been for the home user and the other has been for the professional IT user. The dual routes have generally led to home versions having greater multimedia support and less functionality in networking and security, and professional versions having inferior multimedia support and better networking and security.^{[citation needed]}

The first version of Microsoft Windows, version 1.0, released in November 1985, lacked a degree of functionality and achieved little popularity, and was to compete with Apple’s own operating system.^{[citation needed]} Windows 1.0 is not a complete operating system; rather, it extends MS-DOS. Microsoft Windows version 2.0 was released in November, 1987 and was slightly more popular than its predecessor. Windows 2.03 (release date January 1988) had changed the OS from tiled windows to overlapping windows. The result of this change led to Apple Computer filing a suit against Microsoft alleging infringement on Apple's copyrights.^[9][10]

A Windows for Workgroups 3.11 desktop.

Microsoft Windows version 3.0, released in 1990, was the first Microsoft Windows version to achieve broad commercial success, selling 2 million copies in the first six months.^[11][12] It featured improvements to the user interface and to multitasking capabilities. It received a facelift in Windows 3.1, made generally available on March 1, 1992. Windows 3.1 support ended on December 31, 2001.^[13]

In July 1993, Microsoft released Windows NT based on a new kernel. NT was considered to be the professional OS and was the first Windows version to utilize preemptive multitasking.^{[citation needed]}. Windows NT would later be retooled to also function as a home operating system, with Windows XP.

On August 24, 1995, Microsoft released Windows 95, a new, and major, consumer version that made further changes to the user interface, and also used preemptive multitasking. Windows 95 was designed to replace not only Windows 3.1, but also Windows for Workgroups, and MS-DOS. It was also the first Windows operating system to use Plug and Play capabilities. The changes Windows 95 brought to the desktop were revolutionary, as opposed to evolutionary, such as those in Windows 98 and Windows Me. Mainstream support for Windows 95 ended on December 31, 2000 and extended support for Windows 95 ended on December 31, 2001.^[14]

The next in the consumer line was Microsoft Windows 98 released on June 25, 1998. It was substantially criticized for its slowness and for its unreliability compared with Windows 95, but many of its basic problems were later rectified with the release of Windows 98 Second Edition in 1999.^{[citation needed]} Mainstream support for Windows 98 ended on June 30, 2002 and extended support for Windows 98 ended on July 11, 2006.^[15]

As part of its "professional" line, Microsoft released Windows 2000 in February 2000. The consumer version following Windows 98 was Windows Me (Windows Millennium Edition). Released in September 2000, Windows Me implemented a number of new technologies for Microsoft: most notably publicized was "Universal Plug and Play". During 2004 part of the Source Code for Windows 2000 was leaked onto the internet. This was bad for Microsoft as the same kernel used in Windows 2000 was used in Windows XP.

In October 2001, Microsoft released Windows XP, a version built on the Windows NT kernel that also retained the consumer-oriented usability of Windows 95 and its successors. This new version was widely praised in computer magazines.^[16] It shipped in two distinct editions, "Home" and "Professional", the former lacking many of the superior security and networking features of the Professional edition. Additionally, the first "Media Center" edition was released in 2002,^[17] with an emphasis on support for DVD and TV functionality including program recording and a remote control. Mainstream support for Windows XP ended on April 14, 2009. Extended support will continue until April 8, 2014.^[18]

In April 2003, Windows Server 2003 was introduced, replacing the Windows 2000 line of server products with a number of new features and a strong focus on security; this was followed in December 2005 by Windows Server 2003 R2.

On January 30, 2007 Microsoft released Windows Vista. It contains a number of new features, from a redesigned shell and user interface to significant technical changes, with a particular focus on security features. It is available in a number of different editions, and has been subject to some criticism.

Security

Security has been a hot topic with Windows for many years, and even Microsoft itself has been the victim of security breaches.^{[citation needed]} Consumer versions of Windows were originally designed for ease-of-use on a single-user PC without a network connection, and did not have security features built in from the outset.^[21][22][23]

Windows NT and its successors are designed for security (including on a network) and multi-user PCs, but were not initially designed with Internet security in mind as much since, when it was first developed in the early 1990s, Internet use was less prevalent.^[24]

These design issues combined with flawed code (such as buffer overflows) and the popularity of Windows means that it is a frequent target of computer worm and virus writers. In June 2005, Bruce Schneier’s Counterpane Internet Security reported that it had seen over 1,000 new viruses and worms in the previous six months.^[25]

Microsoft releases security patches through its Windows Update service approximately once a month (usually the second Tuesday of the month), although critical updates are made available at shorter intervals when necessary.^[26] In Windows 2000 (SP3 and later), Windows XP and Windows Server 2003, updates can be automatically downloaded and installed if the user selects to do so. As a result, Service Pack 2 for Windows XP, as well as Service Pack 1 for Windows Server 2003, were installed by users more quickly than it otherwise might have been.^[27]

Windows File Permissions

All Windows versions from Windows NT 3 have been based on a file system permission system referred to as AGLP (Accounts, Global, Local, Permissions) AGDLP which in essence where file permissions are applied to the file/folder in the form of a 'local group' which then has other 'global groups' as members. These global groups then hold other groups or users depending on different Windows versions used. This system varies from other vendor products such as Linux and NetWare due to the 'static' allocation of permission being applied directory to the file or folder. However using this process of AGLP/AGDLP/AGUDLP allows a small number of static permissions to be applied and allows for easy changes to the account groups without reapplying the file permissions on the files and folders.

Windows Defender

On January 6, 2005, Microsoft released a Beta version of Microsoft AntiSpyware, based upon the previously released Giant AntiSpyware. On February 14, 2006, Microsoft AntiSpyware became Windows Defender with the release of Beta 2. Windows Defender is a freeware program designed to protect against spyware and other unwanted software. Windows XP and Windows Server 2003 users who have genuine copies of Microsoft Windows can freely download the program from Microsoft's web site, and Windows Defender ships as part of Windows Vista and 7.^[28]

Third-party analysis

In an article based on a report by Symantec,^[29] internetnews.com has described Microsoft Windows as having the "fewest number of patches and the shortest average patch development time of the five operating systems it monitored in the last six months of 2006."^[30] Furthermore the number of vulnerabilities found in Windows has significantly increased— Windows: 12+, Red Hat + Fedora: 2, Mac OS X: 1, HP-UX: 2, Solaris: 1.

A study conducted by Kevin Mitnick and marketing communications firm Avantgarde in 2004 found that an unprotected and unpatched Windows XP system with Service Pack 1 lasted only 4 minutes on the Internet before it was compromised, and an unprotected and also unpatched Windows Server 2003 system was compromised after being connected to the internet for 8 hours.^[31] However, it is important to note that this study does not apply to Windows XP systems running the Service Pack 2 update (released in late 2004), which vastly improved the security of Windows XP.^{[citation needed]} The computer that was running Windows XP Service Pack 2 was not compromised. The AOL National Cyber Security Alliance Online Safety Study of October 2004 determined that 80% of Windows users were infected by at least one spyware/adware product.^[32] Much documentation is available describing how to increase the security of Microsoft Windows products. Typical suggestions include deploying Microsoft Windows behind a hardware or software firewall, running anti-virus and anti-spyware software, and installing patches as they become available through Windows Update.^{[citation needed]}

Windows Lifecycle Policy

This section needs additional citations for verification.
Please help improve this article by adding reliable references. Unsourced material may be challenged and removed. (January 2009)

Microsoft has stopped releasing updates and hotfixes for many old Windows operating systems, including all versions of Windows 9x,^[33] and earlier versions of Windows NT. Windows versions prior to Windows 2000 are no longer supported. No new updates are created for unsupported versions of Windows.

Emulation software

Emulation allows the use of some Windows applications without using Microsoft Windows. These include:

Wine — a free and open source software implementation of the Windows API, allowing one to run many Windows applications on x86-based platforms, including Linux and Mac OS X. Wine developers refer to it as a "compatibility layer";^[34] and make use of Windows-style APIs to emulate the Windows environment.

CrossOver — A Wine package with licensed fonts. Its developers are regular contributors to Wine, and focus on Wine running officially supported applications.
Cedega — TransGaming Technologies' proprietary fork of Wine, designed specifically for running games written for Microsoft Windows under Linux. A version of Cedega known as Cider is used by some video game publishers to allow Windows games to run on Mac OS X. Since wine was licensed under the LGPL Cedega has been unable to port the improvements made to wine to their proprietary codebase.
Darwine — A bundling of Wine to the PowerPC Macs running OS X by running wine on top of QEMU. Intel Macs use the same Wine as other *NIX x86 systems.

ReactOS — An open-source OS that is intended to run the same software as Windows, originally designed to simulate Windows NT 4.0, now aiming at Windows XP compatibility. It has been in the development stage since 1996.
