Passing The CCNA and CCNP: Three Myths About Cisco Exams
One of the drawbacks to the Internet is that it allows myths and “friend of a friend” stories to spread quickly, and usually the story becomes more exaggerated as it’s passed along. Cisco exams are no exception. Here are three often-repeated myths and exaggerations regarding the CCNA and CCNP exams.
1. The survey you fill out before the exam determines the questions you’ll get. Before you actually start your exam, Cisco presents you with a survey asking how you prepared and how comfortable you feel with certain technologies. It’s a little awkward to rate yourself on Frame Relay, ISDN, etc., especially since the exam you’re about to take covers those subjects. It’s human nature to think that these questions impact your exam, but they do not.
I’ve seen posts on the Net saying that if you rank yourself as “great” in a subject, your exam will have harder questions on that topic, and if you rank yourself lower in that same subject, your exam will be filled with questions on this topic. Cisco has debunked this myth, so get it out of your mind. Don’t think too much when you’re filling out the survey.
2. If you miss a question, the exam keeps asking you about that topic until you get one right. This is known as “adaptive testing”, and Cisco does not use this kind of testing in its exams. Your questions are drawn from a large question pool before you start the test. Those of us who remember adaptive testing from Novell exams years ago don’t particularly miss this kind of testing! (For those who haven’t taken an adaptive exam, you never knew how many questions you were going to get, only that there was a minimum around 15 questions. Your exam could end at any time after that. Nerve-wracking!)
3. If you use an extra command in the simulator questions, it’ll be marked wrong. The Cisco simulator engine in the CCNA and CCNP exams acts just as a router or switch would. You are not going to be penalized for using an extra command. If the engine doesn’t accept a command, you’ll be told that when you use it. Just configure it as you would a router or switch.
When you walk into the exam room totally prepared with a combination of theoretical knowledge, hands-on experience, and configuration troubleshooting skills, you are ready to pass. Don’t let Internet gossip distract you from the task at hand — passing!
This article is about how to improve you Cat5e network connectivity with the CAT5E patch panels, which offers organization, convenience and inexpensive solution for your networking operations. Cat5e Patch Panel wiring is a fast and easy way to configure your Ethernet network with a Cat5e cables,Cat5e keystone jackand plugs, patch cables and other cable management products.
As we know, Internet connections are very common in some high density working areas such as the office building, businesses centers that many workers in different offices or floors that all needed to wired for Internet service from the central server. Wring the Internet from each usages site to the central serve is a must, but is creates a large mass of incoming cables in the server area which must be properly organized with a patch panel. By using the patch panel, it help could label where the other end of the wire is (usually by floor and room number), allowing you to keep your sanity because everything is organized. As a result, it will make connecting PCs or accessories to the networks becomes fast and simple.
Take Cat5e patch panel wiring for example, this article will show you how to wire a Cat5e patch panel step by step.
They are T568A and T568B. Either one is fine as long as you use the same standard at each end of the wire. The difference between the two standards are only color, the way the pairs are grouped is still the same.
Tools you need:
Cat5E Patch Panel
A Network cable tester
110 punch down tool
All of them you can get from some fiber optic or copper network solutions providers such as FiberStore.
Step1. Select a place to mount the panel in the place where the network wires end.
Step2. Examine the 110-style punch down connectors on the back of the Cat5e patch panel, Making sure there are enough patch connectors on the patch panels to accommodate all of the incoming Ethernet cables. You will also see “A” and “B” color code. Use “B” code, which is the common network standard.
Step3. Use the cable strippers to cut off the cable jacket about 1.5 inches from the end of each cable. Take off the scored jacket. If the incoming Ethernet cables are RJ6 type, they will have an internal plastic jacket under the outer cable jacket that must be carefully removed and discarded using wire cutters.
Step4. You will see 4 twisted pairs of wires inside the Ethernet cable. Untwist all of the wires and spread them out. The wires are color coded with 4 being solid colors, and 4 with a white stripe around the color.
Step5. Place all the 8 wires into the 110 style connectors of the patch panel in the patch panels outlet that is used to receive the incoming cables. You will see the color code labels on the patch panel. Match al cables to the corresponding color in the “B” color scheme.
Step6. Use a110 punch down toolto firmly press down on each wire to make sure it is grasped by both sets of teeth of the insulation displacement connector. Punch down tool is with a cutting edge, you can use it to cut the excess wire of the Ethernet cables during the pushing process.
Step7. This step is optional but recommended. Mark the terminated incoming cables with a label indicating where the cables is from with the room or floor numbers. It will help you locate the system problems precisely or handing the futures upgrading projects.
Step8. Use a cable tester to assure that you correctly terminated all the wires.
Now you can plug a short patch cable from the desired port on the patch panel to the closely located hub or switch. The other end of the wire would be terminated at a wall socket (sometimes called a drop).

If you’ve never owned an Apple computer, you don’t know what you’re missing. On the other hand, if you regularly use Macintosh computers, you understand that once you have a Mac, you’ll never go back. An Apple Macintosh – whether it’s a MacBook, a Mac Pro, or an iMac – takes personal computing to a whole new level. I bought my first iMac in 1998, have upgraded twice, and am still happy as a proverbial clam. Here, then are five reasons to love the Apple Macintosh.
1. Cool elegance. If there’s one thing Steve Jobs knows how to do, it’s designing electronics that are ultra-cool yet beautifully elegant. Why have a cumbersome big box desktop computer when you can have everything you need in an elegant iMac? Behind that clear, bright 16:10 aspect ratio monitor is the entire computer, including a DVD drive and a 64-bit Intel Core 2 Duo processor. There’s even a webcam built into the iMac so you can video chat or video conference whenever the whim strikes.
2. Intuitive functionality. Even though Windows copied the friendly desktop interface from Apple Macintosh, they still haven’t been able to get it right. Navigating the Mac’s interface is truly intuitive, engaging, and just downright fun. With a mobile computing product like the MacBook, you can take full computing functionality wherever you go. And, wherever you’ll go, you’ll always be connected, since the MacBook automatically finds nearby wireless networks and gives you nearly instant online access.
3. Digital living. Macintosh computers are designed to embrace the digital lifestyle. MacBooks and iMacs come with iLife, a wonderful array of applications that let you effortlessly share photo albums, record podcasts and songs, and even create and edit movies. You can even publish your creations on the Web with a single click. How cool is that?
4. Bug-free. If you’ve been wrestling with Vista the past few months (or any other Windows operating system, for that matter), you don’t know the meaning of freedom. Macintosh computers’ operating systems are bug-free, and as for upgrades, you get to choose when to receive software update notifications, and always have the choice of updating now or in the future. Mac simply isn’t intrusive; you get to control technology, instead of having technology control you.
5. Workhorse. Macintosh computers are more than a way to frolic in your spare time. They’re also workhorses. For years, graphic artists and publishers have almost exclusively used Macs for work. With the Mac Pro, you can get Adobe Creative Suite 3, a suite of tools specifically designed for creative professionals. Whether you’re a web designer, a graphic artist, an art director, or a video professional, Adobe Creative Suite 3 will make your work easier, better, and more fun.
There are those who say that Macintosh computers are limited in that much of the available software is only compatible with PCs. My experience is that my Mac can do anything a PC can do – and do it better. But for those diehards who insist that they can’t live without Windows, the next version of Mac OSX, Leopard, will allow you to install Windows XP on the Mac. Right now, you can run Windows in emulation mode…although for the life of me, I don’t understand why you would want to!
Basically a digital camera is a deice use to capture pictures without the use of films. Unlike the conventional camera, the digital camera does not rely on mechanical and chemical processes. It has a built in computer and records the images it captures in an electronic form. Having and operating one does not even require the use of electricity.
Since the images that a digital camera captures is in electronic form, it is a language recognized by computers. This language is called pixels, tiny colored dots represented by ones and zeros that make up the picture that you just took. Just like any conventional cameras, a digital camera is furnished with a series of lenses that focus the light and creates the image that you want to capture. The difference here is then; a conventional camera focuses its light on a film while a digital camera focuses the light into a semiconductor device that electronically records the light. Remember the built in computer, it comes in here and breaks this information to digital data resulting to all the features of the digital camera.
Another feature of the digital camera is that it has a sensor that converts light into electrical charges. A charge coupled device or CCD is an image sensor that is found in a digital camera. While other low-end digital camera use complementary metal oxide semiconductor or CMOS as an image device, it can still become better and more famous in the future but most engineers are do not believe that it can replace the CCD for higher-end digital cameras.
A collection of tiny diodes, the CCD gathers electrons when they are struck by photons or the light particles. Each diode or photosite is sensitive to light, meaning that the brighter the light, the number of the electrons gathering will be larger
The price of a digital camera nowadays have been depreciating, one of the main reasons of this is because of the introduction of CMOS image sensors, this is because CMOS sensors are less expensive and are easier to manufacture than CCD sensors. A CCD and CMOS sensor works the same way at first, by converting the light electrical charges into photosites. Simply putting it, is to think that a digital camera works in such a way as thinking that the millions of tiny solar cells, each of which forms a part of the whole image. Both CCD and CMOS do this task using different methods.
When shopping for the best digital camera, take note of these key features.
Image quality. Check the resolution of the camera. The higher the resolution, the more thou will be able to enlarge your picture without the grainy or the out-of-focus effect that we all want to avoid.
Lens. Choose a digital camera with better digital zoom. The digital zoom of the camera will enable you take the pixels from the image sensor and incorporate them to make an image.
Power. Always opt for rechargeable batteries, they can always come in handy, plus you dont waste as much money on the disposable ones.
Options. So you can brag to your friends how good a photographer or artist you are. Or choose the one that gives options that best cater to your lifestyle, so you wont ever whine how you never get the right pictures.
Memory. If youre a photo freak, be sure that you have enough memory in your camera to take all the wacky, freaky, funny and just about any photo you can. Think 512MB if youre a photo junkie and takes pictures of just about anything.
Computer Interface. Always make sure that it is compatible with your PC, laptop, palmtop or whatever your local picture printer software is, you dont want to go running around the whole state or the country looking for a computer thats compatible with your digital camera, wont you?!
Physical. If you are going to be bringing it everywhere, choose a handy and portable digital camera. This way, it wont always feel as heavy and bulky as those cameras that you see professional photographers are always dragging on their neck. Dont they ever get tired of that?!
These are just the basic things you have to look for in a digital camera when you buy one. A digital camera is so great that it is quickly replacing all conventional cameras in the market, with all its technology and portability, truly the digital camera is the future of cameras.
