The rainbow flag has become one of the most widely used and recognized symbols of the gay pride movement. The concept of the rainbow is hardly a new one. Rainbows have used since ancient times in all kinds of cultures- Greek, African, Native American and Celtic, to name only a few. Even Jesse Jackson's Rainbow Coalition has made use of the rainbow has a freedom symbol.
Use of the rainbow flag by the gay community began in 1978 when it first appeared in the San Francisco Gay and Lesbian Freedom Day Parade. Borrowing symbolism from the hippie movement and black civil rights groups, San Francisco artist Gilbert Baker designed the rainbow flag in response to a need for a symbol that could be used year after year. Baker and thirty volunteers hand-stitched and hand-dyed two huge prototype flags for the parade. The flags had eight stripes, each color representing a component of the community: hot pink for sex, red for life, orange for healing, yellow for sun, green for nature, turquoise for art, indigo for harmony, and violet for spirit.
The next year Baker approached San Francisco Paramount Flag Company to mass-produce rainbow flags for the 1979 parade. Due to production constraints -- such as the fact that hot pink was not a commercially-available color -- pink and turquoise were removed from the design, and royal blue replaced indigo. This six-color version spread from San Francisco to other cities, and soon became the widely-known symbol of gay pride and diversity it is today. It is even officially recognized by the International Congress of Flag Makers. In 1994, a huge 30-foot-wide by one-mile-long rainbow flag was carried by 10,000 people in New York's Stonewall 25 Parade.

What is a stillbirth?
Stillbirth is the death of a baby after the 20th week of pregnancy, but before delivery. The baby may have died in the uterus weeks or hours before labor, or during labor.
How common are stillbirths?
About one in every 150 births, or 1% of all births, is a stillbirth.
What causes stillbirths?
The three major causes of stillbirths are:
Unfortunately, more than half of stillbirths are unexplained, which only adds to parents' grief.
What happens after a stillborn baby is delivered?
You will be able to hold your baby, and your health care providers will allow you as much time as you need to spend with your child. You may feel uncomfortable with this idea, but it will be a cherished moment at a later time.
Keep and ask for any mementos and keepsakes of your child such as the I.D. bracelet, blanket, or a lock of your child's hair, and take as many pictures as possible. As with holding your baby, this may also be uncomfortable but it may be a cherished possession at a later time and may help you during your grieving process. Most hospitals will issue the family a birth certificate, but make sure you ask so you are sure to get one, and request that it include the baby's hand and footprints.
Test and examinations
The doctor will carefully examine the baby and placenta to check for abnormalities, and parents may be asked to consent to an autopsy and other studies. In most cases, a blood sample will be taken from the baby and tested for chromosomal abnormalities.
The doctor will also review medical records and the circumstances surrounding the stillbirth.
How can I find out what caused my baby to be stillborn?
Pending your consent, an internal examination (autopsy) can be performed to determine the cause of your baby's death. An autopsy is a surgical procedure performed by a skilled pathologist. Incisions are made to avoid any disfigurement. The incisions are surgically repaired in the usual way. A doctor can explain the procedure in more detail. You have the right to limit the autopsy to eliminate any incisions on your baby that are not comfortable for you (for instance, you can give instructions that no incisions are to be made on the baby's head). Be sure to write these requests on the autopsy permission form.
Some hospitals do not perform their own autopsies, so your baby may have to be transported to another hospital. Be sure you feel comfortable about where your child is being taken.
You have the right to deny an autopsy, if this is your wish.
An autopsy is legally required when:
What physical symptoms will the mother have after delivering a stillborn baby?
If you have heavy bleeding, fever, chills or pain, contact your health care provider right away. These may be signs of an infection.
After the delivery of the placenta, the milk-producing hormones will be activated. Please talk to your health care provider about your options to stop lactation.
Can a stillbirth be prevented?
Usually a stillbirth cannot be prevented and often occurs because the baby's development was not normal.
Sometimes, treatment of a mother's illness can improve the chances for a successful pregnancy.
Is a funeral necessary?
After the death of your baby, one of the first decisions you will be faced with is whether or not you need to arrange a funeral.
The type of arrangements you make may play an important role in the grieving process. It is a decision that only you and your partner can reach together. You may find that you need time to make your decisions and arrangements. It is quite common for families to take up to a week (and sometimes longer) to make arrangements. This is okay.
No matter what your choice is, you have the right to change your mind " be sure you ask whoever is carrying out your arrangements just how long you have to make any changes.
How to communicate with your other children?
You may find your surviving children are a comfort, a worry or just too hard to deal with. These are normal reactions. Take time to grieve and say goodbye to the child you lost. You will eventually feel more normal feelings for your living children, and the bond you have with them may become even stronger because of this experience.
No matter how much you may want to shelter your children from pain, they can sense the emotion around them. Honesty is the best way to help your children cope with this painful experience. Children have a different understanding of death at different developmental stages. Help them to understand as much as they are able, but don't forget that they usually interpret what they're told very literally.
Can I get pregnant after I've delivered a stillborn baby?
Yes. Most women who deliver stillborn babies have subsequent normal pregnancies and births. If the stillbirth was caused by a malformation or umbilical cord problem, the chances of recurrence in a subsequent pregnancy are minimal. If the cause was a chronic maternal illness or a genetic disorder, the risk is somewhat higher. On average, the chance that a woman's next pregnancy will result in stillbirth is about 3%, which means the majority of post-stillbirth pregnancies result in healthy births.
Taking time to heal both physically and emotionally after delivering a stillborn baby is important. Regardless of the stage of pregnancy during which your loss occurred, you are still a mother or father and the life you nurtured was real. Above all, don't blame yourself. Give yourself time to grieve and accept your loss. Counseling is available to help you cope. Pregnancy loss support groups may also be a valuable resource to you and your partner. Ask your health care provider for more information about counseling and support groups.
Discuss the timing of your next pregnancy with your health care provider to ensure that you are physically ready to begin a new pregnancy. Some health care providers recommend waiting a certain amount of time (from 6 months to 1 year) before trying to conceive again. Some studies have shown that women who wait for at least one year to conceive may have less depression and anxiety during a subsequent pregnancy.
Statistics show that about 60% of couples take up to 6 months to conceive and another 30% take up to 12 months after delivery of a stillborn baby. Don't be surprised if things don't happen quickly.

SANTA CLARA, Calif., August 19, 2010 - Cameron Diaz has replaced Jessica Biel as the most dangerous celebrity to search for on the Web, according to security company McAfee, Inc. (NYSE:MFE). For the fourth year in a row, McAfee researched popular culture's most famous people to reveal the riskiest celebrity athletes, musicians, politicians, comedians and Hollywood stars on the Web.
The McAfee Most Dangerous CelebritiesTM study found movie stars and models top the "most dangerous" list this year while politicians like Barack Obama and Sarah Palin are among the safest.
Cybercriminals often use the names of popular celebrities to lure people to sites that are actually laden with malicious software. Anyone looking for the latest videos or pictures could end up with a malware-ridden computer instead of just trendy content.
"This year, the search results for celebrities are safer than they've been in previous years, but there are still dangers when searching online," said Dave Marcus, security researcher for McAfee Labs. "Through consumer education and tools, such as McAfee® SiteAdvisor® site ratings, consumers are getting smarter about searching online, yet cybercriminals are getting sneakier in their techniques. Now they're hiding malicious content in 'tiny' places like shortened URLs that can spread virally in social networking sites and Twitter, instead of on websites and downloads."
Cameron Diaz Searches Yield Ten Percent Chance of Landing on a Malicious Site
McAfee research found that searching for the latest Cameron Diaz pictures and downloads yields a ten percent chance of landing on a website that's tested positive for online threats, such as spyware, adware, spam, phishing, viruses and other malware.
Fans searching for "Cameron Diaz" or "Cameron Diaz and downloads," "Cameron Diaz and screen savers," "Cameron Diaz and wallpaper," "Cameron Diaz and photos" and "Cameron Diaz and videos" are at risk of running into online threats designed to steal personal information. Clicking on these risky sites and downloading files like photos, videos or screensavers exposes surfers or consumers to the risk of downloading the viruses and malware.
The study uses SiteAdvisor site ratings, which indicates which sites are risky to search for celebrity names on the Web and calculate an overall risk percentage. The top 10 celebrities from this year's study with the highest percentages of risk are:
| Position | Celebrity |
| 1 | Cameron Diaz – Searching for Diaz results in a one in ten chance of landing on a risky site. She has most recently been in the spotlight with blockbuster movies, "Knight and Day" and "Shrek Forever After." When "Cameron Diaz and screensavers" was searched, 19 percent of the sites were identified as containing malicious downloads. |
| 2 | Julia Roberts – Academy Award-winning actress Julia Roberts is one of America's sweethearts, and will soon be in the spotlight with her upcoming release of "Eat, Pray, Love." The overall risk of searching for Roberts is nine percent, yet searching for "Julia Roberts and downloads" results in a 20 percent chance of downloading a photo, wallpaper or other file laden with malware. |
| 3 | Jessica Biel – Last year's Most Dangerous Celebrity fell two spots with searches resulting in fewer risky sites this year. Biel continues to be in the spotlight with her on-again, off-again relationship with Justin Timberlake, and appeared in "The A-Team" in June 2010. While her overall search risk is nine percent, searching for "Jessica Biel and screensavers" results in a 17 percent chance of landing on a risky site. |
| 4 | Gisele Bündchen – The world's highest-paid supermodel moved up two spots since last year. Searching for "Gisele Bündchen and screensavers" can prove risky, 15 percent of the search results for this beauty can put spyware, malware or viruses on your computer. |
| 5 | Brad Pitt – Pitt is often in the spotlight with news of his movies and his personal life. It's no wonder why this leading man has been in the top ten for the past three years. He moved up in rank five spots this year. Downloading photos, screensavers, or other files of Brad can potentially put adware or spyware in your computer. |
| 6 | Adriana Lima – Searching for downloads of this Brazilian beauty can direct users to red-ranked sites. Lima is best known for being a Victoria's Secret Angel since 2000. |
| 7 | Jennifer Love Hewitt, Nicole Kidman – Searching for these Hollywood starlets resulted in an equal number of risky download websites. |
| 8 | Tom Cruise – With recent buzz around his MTV Awards performance as well as his movie, "Knight and Day," Cruise rises to the top ten. |
| 9 | Heidi Klum, Penelope Cruz – Both of these ladies are consistently in the spotlight, and share the #9 spot. Cybercriminals use their names to lure people to risky sites. Klum hosts "Project Runway" and Cruz has been in the spotlight recently for her role in the "Sex and the City 2" movie and is expected to be in the fourth film of the "Pirates of the Caribbean" series. |
| 10 | Anna Paquin – This "True Blood" star is as dangerous on the Web as she is on the screen. Searching for screensavers of Paquin can lead you to downloads filled with malware. |
"Cybercriminals follow the same hot topics as consumers, and create traps based on the latest trends," continued Marcus. "Whether you're surfing the Web from your computer or your phone or clicking on links in Twitter about your favorite celeb, you should surf safely, and make sure you're using the latest security software."
Beware of Victoria's Secret Beauties
Three of Victoria's Secret top models are among the top ten this year. Searching for downloads of sexy Gisele Bündchen (#4), Adriana Lima (#6), and Heidi Klum (#9) can result in landing on a high percentage of risky sites.
Dangerous Athletes
Tennis stars Maria Sharapova and Andy Roddick came in at (#13) and (#14) respectively. Most of the risky sites were uncovered when searching for screensavers featuring these sexy athletes. David Beckham ranked (#29) and Tiger Woods ranked (#33) this year.
"Bieber Fever" is Not Dangerous
Teen sensation Justin Bieber ranked towards the bottom of the list at #46. This young star recently broke a YouTube record with more views than Lady Gaga (#37). Other young Hollywood stars like Miley Cyrus (#44) and Zac Efron (#40) were also relatively safe to search.
Obama and Palin at the Bottom of the Pack
President Barack Obama (#49) and Sarah Palin (#50) are not among the most risky personalities to search; they ranked in the bottom of this year's results, moving even lower on the list compared to last year.
Keep Safe with McAfee SiteAdvisor Plus software
McAfee security experts urge consumers to surf safely by using McAfee SiteAdvisor Plus software ($19.99). It displays red, yellow and green icons on the search results page that indicates the safety-level of websites. It also checks the safety of links in e-mail and instant messaging applications, blocks risky websites, adds anti-phishing protection, and helps users more safely surf, shop and bank online. SiteAdvisor Plus software is already included with McAfee Total Protection™ software, a comprehensive security suite that protects against antivirus, anti-spyware, and identity and firewall protection.
Consumers can also safely surf the Web by using the Yahoo! SearchScan toolbar, which only shows ratings for "red" sites that are have potentially dangerous downloads including viruses, spyware and other harmful software.
Web surfers should visit the McAfee Security Advice Center and Facebook page at www.facebook.com/mcafee for information on the latest threats, and tips on surfing safely.

In this article I'm going to explain what a podcast is and why it's becoming such a popular media. This is going to be an easy to understand podcast definition in everyday terms.
If you prefer "geek-speak" and pride yourself in the use of jargon, click here to see a brief podcasting definition in technical terms.
A podcast is a digital audio file (usually MP3 or AAC) made available for download on the internet through an RSS 2.0 feed. The web address of the media file is contained in the enclosure tag of an item in the XML file. The enclosure tag was added to the RSS 2.0 standard in 2004 making podcasting possible.
A podcast's RSS feed is updated each time a new media file is published. An aggregator for podcasts (such as iTunes or iPodder) is used to subscribe to the RSS feed. The software automatically checks for and downloads new audio files. The file can then be synced to a digital audio player.
It is the convenience of this subscription model that sets podcasting apart from other audio available on the internet such as streaming and audioblogging. Podcasting makes it easy to create and disseminate digital audio content across the web.
The enclosure tag can be used to any type of digital file, but not all aggregators recognize and download all file types. Vidcasts have started to emerge on the internet distributing digital video files.
Podcasting offers a variety of content for listeners to consume how they want, when they want and where they want.
Hopefully this definition contained enough big words to make it a sufficiently techie definition of what is podcasting? Are you impressed?
Continue reading for a more complete explanation of podcasting.
You're about to see how you can find a huge variety of new and interesting content from the internet to fill your MP3 player for free. You can listen to what you want, when you want, and how you want.
Imagine getting new "radio"-style talk and music shows to listen to on your iPod or other MP3 player every day. You wake up and automatically have new shows ready to listen to while you exercise or commute to work. This is the podcast listening experience.
Not only that, but anyone can create his or her own "radio"-style show and broadcast it to the world in very little time and at very little cost. All you need is a computer, a mic and the internet.
When I first heard about podcasting I was blown away. I spent a week reading everything I could about podcasts and finding new podcasts to listen to. I was so excited about the idea of so much free, original and interesting content to listen to. I could also sense that this was going to be an amazing new way to share content across the internet and to millions of mp3 players.
Let's face it. Broadcast radio is getting old. The same songs get played over and over until you're sick of them. A few large companies have control of the formats and what gets played. There is no variety.
If I listen to the radio while driving, one hand is on the "scan" button and the other is on the wheel. As soon as something loses my interest, I tap the button—and I tap it a lot.
With podcasts you don't have to wait to hear something that interests you. You choose what you want to listen to. There are now thousands of podcasts and the number is growing rapidly.
Podcasting has leveled the playing field. Anyone with something to say and a desire to say it can create a podcast and publish it to the world.
Podcasters (as they are called) are not restricted by the FCC or traditional broadcast formats and regulations. This allows for numerous subjects and formats.
Podcasting is an escape from the same old, corporate conglomerate, worn-out, Clearchannel controlled, pre-programmed, blah blah blah radio. Podcasting has personality and variety that run-of-the-mill radio does not.
The word podcast is a play on the word broadcast combined with the word iPod (one of the most popular portable MP3 players). Apple did not invent the word podcast, although I'm sure they are enjoying the free marketing they are getting from the popularity of podcasting.
You do not have to have an iPod to listen to a podcast. In fact, I personally believe there are many other MP3 players that are better for listening to podcasts. You can listen to podcasts on anything that plays MP3s. Once the podcast is downloaded, it's just an MP3.
Anyone can create a podcast. All over the world, people are creating podcasts on subjects ranging from movies, to technology, to music, to politics and whatever else you can think of. This is new original content made by passionate people who want to share their creativity with the world.
The cost to start podcasting is so low that anyone can do it. Most podcasters are everyday people like you and me. They could be talking to you driving in their car, sitting in their living room or speaking at a conference. You get to glimpse into their life and into their interests.
Podcasters are creating very raw and real content and listeners are responding. Free from corporate radio and broadcast regulations, you can create whatever kind of show you can imagine.
Some podcasts are "talk show" style. Others introduce you to the latest bands and music. With podcasts you can stay current on the news, get a glimpse into someone's life, listen to move reviews and the list goes on.
Most podcasts are made by people who are very passionate about their subject. Passion is infectious and interesting to listen to. Since the birth of podcasting, a huge variety of shows have shown up on the internet.
In addition, many major media outlets are also now offering podcasts. You can listen to NPR, Rush Limbaugh and many major news outlets by podcast.
Maybe you're still wondering what all the hype is about. MP3s have been on the internet for quite some time. Internet radio is nothing new. Audio blogs have been around for awhile, too.
What sets podcasts apart is that they can be automatically downloaded to your computer and synced to your MP3 player without you lifting a finger. You can wake up each morning with new shows on your MP3 player ready to listen on your way to work.
This ease and convenience of this automatic delivery is powerful. This is what sets podcasting apart and made it so popular. Imagine walking into Starbucks to get a drink and by the time you leave you have new shows to listen to on your MP3 player. We haven't reached that point yet, but we are headed there.
This amazing technology came out of the minds of David Winer and Adam Curry (you may remember Adam was a VJ on MTV in the mid-80s). Adam wanted an easy way for people to create audio content and for listeners to automatically receive it to their MP3 players.
David had the basic feed technology (explained below) in place to make it happen. Together they put together the foundation that would become podcasting. You can read more about the history of podcasting here.
At the core a podcast is an audio file that is automatically received from the internet and then synced to your MP3 player. The files are received by subscribing to what's called a podcast feed. Sometimes you also hear this called an RSS feed, but that is just geek speak that gets used to try and impress you.
Maybe you have seen the small orange icons that look like this or this on some web pages. This icon is a link to a news feed. Blogs use this kind of feed to deliver new content to their subscribed readers.
The same kind of feed is used to deliver podcast shows to your computer. You don't need to know how the feed works to subscribe. You just need to know that you can subscribe to a podcast feed to get the latest shows when they are released.
You don't have to remember to check for new shows. You don't have to download it. It's done for you.
You can think of a podcast as being like a magazine because you subscribe to it and receive new content regularly.
Even though subscribing to a feed is the most convenient way to receive podcast, you don't have to subscribe to listen. Many podcasts can also be streamed from the web or downloaded directly as an MP3 file.
To subscribe to a podcast you use a software program called a podcatcher. Sometimes this is also called a podcast aggregator (but again this is geek speak). Just know that podcatcher and aggregator mean the same thing. It's the software that you use to subscribe to and receive podcasts.
The podcatcher regularly checks the feed for new content that has been posted. When a new podcast show is found, it's downloaded. The next time you plug your MP3 player into your computer, the new podcasts shows are synced by your media player (such as iTunes).
With podcasts, you're in control. Earlier I mentioned that a podcast is kind of like a magazine subscription. Podcasts are also like Tivo because you're in control of when you listen to it.
You can rewind a podcast. You can play it over and over. You can pause it. You can store it wherever you want. You can delete it when you want. Podcasts give you the control.
You can listen to podcasts on your computer, burn them to CD or transfer them to your MP3 player. You're in control of when and how you listen.
Compare that to listening to the radio. Big corporations decide what you get to listen to and when you listen to it. It's all controlled by what will make them money. Now you can have radio your way.
Unlike streaming audio, you can take a podcast with you. To listen to streaming content you're tied to a computer with a fast internet connection.
Now compare podcasts to a download from iTunes. You're not limited to how many times you can download a podcasts or how many times you can burn it. It's not limited to only playing in certain media players. Speaking of iTunes, with podcasts there are…
If you want something other than 99 cent music downloads to fill your MP3 player, then podcasts are it. Most podcasts are free and there is no limit to how many you can find and subscribe to. You're only limited by how much time you have to listen to them. Maybe you can actually fill that 40 gig drive now.
Just because podcasts are free does not mean that they are not quality. Granted, there are some podcasts that will make you cringe because the content and audio stink. But there are a lot of podcasters out there who are passionate about what they do and make quality shows even though they are free to listen to.
The purpose of most radio content is to keep you listening until the next commercials. Who likes listening to ads? Without commercials, radio would die.
Most podcasts are commercial-free. The cost of podcasting is low enough that podcasters can produce their shows with little or no sponsorship. Even when podcasters do incorporate some advertising it's much less intrusive than the barrage we get on the radio.
You will only automatically receive podcasts that you have subscribed to our downloaded yourself. There is no podcast SPAM. You can unsubscribe if a podcast bores you to death.
Become a Celebrity and Recognized Expert on the Internet.

Start Your Own Podcast.
Since podcasts showed up in Fall 2004 thousands of shows have been created. In the Summer of 2005 iTunes 4.9 added features for podcasts. This generated a huge leap forward in the number of podcast listeners and podcasters.
A popular podcast feed management site, Feedburner, reported that the number of listeners in January 2005 (13,500) almost doubled to 24,000 by February of 2005. This stat is from just one slice of the podcasting feeds on the internet.
Podcasting has become a big buzz word on the web and in the media. New services for listening to and creating podcasts are constantly popping up. This industry is seeing very exciting growth. Podcasting is moving forward at the speed of light.
Despite this rapid growth, we are only scratching the surface. You can still catch this wave. Think of how fun it will be to create your own podcast and become a celebrity on the internet.
People will be listening to what you have to say. They will be enjoying your own creation. You can become and a recognized expert on the topic of your choice. This makes podcasting valuable for business use.
You can leverage this relationship with your audience to make money and promote yourself. Your listeners will become dedicated and will return often for your opinion and expertise.
Now it's time for your pop quiz. Quit your whining. I promise it's easy:
1. What are podcasts:
a) A new type of media that puts you in control of what you listen to, when you listen to it and how you listen to it (usually on a computer or portable audio player)
b) An easy way to share your own audio content on the internet with a focused audience
c) A media that can be created with equipment you probably already own, for little cost and in as little as a day
d) A way to become a recognized expert or celebrity in your niche
e) A powerful way to connect with your customers and promote your business to them on regular basis
f) All of the above (you saw that coming)

ေယဘုယ်အားျဖင့္ RISC Processor ေတြမွာ Instruction တစ္ခုအတြက္ လုပ္ရမယ့္အလုပ္ေတြကို ေအာက္မွာျပထားသလို အဆင့္နဲ႔ခြဲထားပါတယ္။
အလုပ္တစ္ခုဟာ Clock တစ္ခုလုိအပ္တဲ့အတြက္ Instruction တစ္ခုအတြက္ အဆင့္ငါးဆင့္ လုပ္ရမွာျဖစ္လို႔ ပံုမွန္အားျဖင့္ Clock ငါးခုလိုအပ္ပါတယ္။ နမူနာအျဖစ္ အလုပ္လုပ္ပံုကို ေျပာရမယ္ဆိုရင္ 680x0 Instruction နမူနာတစ္ခုအျဖစ္ move.l (a1), d1 ဆိုတာ Memory တစ္ေနရာမွာ ရွိတယ္ဆိုၾကပါစို႔ အဲဒါဆိုရင္ ပထမအဆင့္ IF အေနနဲ႔ အဲဒီ့ Instruction ကို သက္ဆိုင္ရာေနရာကေန ဖတ္ပါတယ္ ဒုတိယအဆင့္ ID အေနနဲ႔ Instruction ကိုဘာလုပ္ခိုင္းသလဲ ခြဲျခားရပါတယ္ ခြဲျခားလိုက္မယ္ဆိုရင္ move လုပ္ရမယ္ လုပ္ရမယ့္ Size က Long ျဖစ္တယ္ a1 ထဲမွာရွိတဲ့ Address မွာသိမ္းထားတဲ့ data ကို d1 ဆိုတဲ့ Register ထဲကိုကူးထည့္ရမယ္လို႔ ခြဲျခားႏိုင္ပါတယ္။ တတိယအဆင့္ EX အေနနဲ႔ သူေျပာထားတဲ့အလုပ္ကို ALU အေနနဲ႔လုပ္ဖုိ႔လိုအပ္ပါတယ္ Execute လုပ္ဖို႔အတြက္ ဒီအတိုင္းလုပ္လို႔မရပါဘူး a1 ထဲမွာရွိတဲ့ Address မွာသိမ္းထားတဲ့ data ကိုဖတ္ဖို႔လိုတဲ့အတြက္ Processor ထဲက Data နဲ႔မလံုေလာက္လို႔ Memory ကို Access လုပ္ဖို႔လိုပါတယ္ အဲဒီ့လိုလုပ္တဲ့အလုပ္ကို စတုတၳအဆင့္အေနနဲ႔ MA လို႔ေျပာလို႔ရမွာျဖစ္ပါတယ္ ေနာက္ဆံုးအဆင့္အေနနဲ႔ ထြက္လာတဲ့အေျဖကို သက္ဆိုင္ရာ ေနရာမွာသြားေရးရပါတယ္ ဒီ Instruction မွာေတာ့ ဖတ္လို႔ရတဲ့ Data ကို d1 ထဲကိုသြားေရးပါတယ္ ဒါဆိုရင္ ပဥၥမအဆင့္ျဖစ္တဲ့ WB ၿပီးဆံုးပါလိမ့္မယ္။ အဲဒါဆိုရင္ေနာက္ထပ္ Instruction တစ္ခုကိုထပ္ဖတ္တဲ့ IF ကေန WB အထိဆက္လုပ္ရင္ Processor ကိုမပိတ္မခ်င္း ဆက္လုပ္ေနမွာျဖစ္ပါတယ္။

အခုအခ်ိန္အထိ အလုပ္တစ္ခုဟာ Clock အျဖစ္သာ အလုပ္လုပ္ေနတယ္လို႔ ယူဆေနတာပါ အဲဒီ့လိုဆိုရင္အလြန္ပဲေႏွးပါလိမ့္မယ္ ေနာက္ၿပီးေတာ့ Processor ရဲ႕အစိတ္အပိုင္းေတြဟာ အလုပ္အျပည့္အဝ အလုပ္ႏိုင္ပါဘူး။ ပံုမွန္အားျဖင့္ IF ဟာ တစ္ႀကိမ္အလုပ္လုပ္ၿပီးရင္ ေနာက္ထပ္ IF မေရာက္မခ်င္း Clock ေလးခု အားေနပါတယ္ အဲဒီ့ေတာ့ အစိတ္အပိုင္း ၅ ခုလံုးသာ တစ္ၿပိဳင္တည္း အလုပ္လုပ္ႏိုင္ရင္ လက္ဆင့္ကမ္းအလုပ္လုပ္သလို အၿပိဳင္အလုပ္လုပ္ႏိုင္ပါတယ္။ ဥပမာအားျဖင့္ IF အလုပ္ၿပီးလို႔ ID ကိုအလုပ္ကို လက္ဆင့္ကမ္းလုိက္ၿပီးရင္ IF အေနနဲ႔ ေနာက္ထပ္ Instruction တစ္ခုကိုယူၿပီးေတာ့ IF အလုပ္ထပ္လုပ္လို႔ရပါတယ္ အဲဒါဆိုရင္ အလုပ္စစခ်င္း Clock ေလးခုကလြဲရင္ ေနာက္အႀကိမ္ေတြမွာ Clock တစ္ခုမွာ Instruction တစ္ခုေပးႏိုင္ပါလိမ့္မယ္။ အဲဒါမ်ိဳးအလုပ္လုပ္တာကို Pipelining လို႔ေခၚပါတယ္။ ေအာက္ကပံုမွာၾကည့္ပါ

အေပၚမွာျပထားသလိုဆိုရင္ အလုပ္ေတြက Clock တစ္ခုမွာ Instruction တစ္ခုေတာ့ ၿပီးေအာင္လုပ္ႏိုင္သြားပါတယ္ အရင္လို Clock ေတြအမ်ားႀကီးမလိုေတာ့ဘူးေပါ့။ ေနာက္တစ္ဆင့္အေနနဲ႔ Clock တစ္ခုမွာ Multiple Instruction ဘယ္လိုလုပ္မလဲဆိုတာ စဥ္းစားရျပန္တယ္။ အယူအဆအားျဖင့္ ရွင္းလင္းပါတယ္ Pipeline တစ္ခုဟာ Single clock per instruction လုပ္ေပးႏိုင္ရင္ Multiple Pipeline ဆိုရင္ Single clock per multiple instruction အလုပ္လုပ္ႏိုင္ပါလိမ့္မယ္ အဲဒါမ်ိဳးကို Superscalar လို႔ေခၚပါတယ္။ ေအာက္မွာျပထားတဲ့ Figure ကိုၾကည့္ပါ Double Pipeline ျဖစ္တဲ့အတြက္ Single clock per double instruction အလုပ္လုပ္ေနတာ ေတြ႔ရပါလိမ့္မယ္။
