When it comes to networks, a good plan means everything. We know you can do it! But before we turn you loose on the world, we want to add a few more things to your toolbox. Some of these things are in all the network books, so we thought we could squeeze them in here. Some of these things are higher level, and we want you to at least be familiar with the terminology and basic concepts.

So before you put the book down, take a read through these tidbits. Installing BIND is fairly simple, but just in case you need some extra reassurance, here are some handy instructions on how to do it. Who should probably back away from this book? Would you rather have a root canal than mix stripes with plaid?

It was built that way, and it helps you stay alive.

So what does your brain do with all the routine, ordinary, normal things you encounter? Neurons fire. Emotions crank up. Chemicals surge. This must be important! Getting ready for an exam. Or trying to learn some tough technical topic your boss thinks will take a week, ten days at the most.

Just one problem. Resources that are better spent storing the really big things. Like tigers. Like the danger of fire. Only more dull, dry, boring pages. Based on the latest research in cognitive science, neurobiology, and educational psychology, learning takes a lot more than text on a page.

We know what turns your brain on. Some of the Head First learning principles: Make it visual. It also makes things more understandable. Put the words within or near the graphics they relate to, rather than on the bottom or on another page, and learners will be up to twice as likely to solve problems related to the content.

Use a conversational and personalized style. Tell stories instead of lecturing. Use casual language. Which would you pay more attention to: Get the learner to think more deeply. In other words, unless you actively flex your neurons, nothing much happens in your head.

A reader has to be motivated, engaged, curious, and inspired to solve problems, draw conclusions, and generate new knowledge. And for that, you need challenges, exercises, and thought-provoking questions, and activities that involve both sides of the brain and multiple senses.

Your brain pays attention to things that are out of the ordinary, interesting, strange, eye-catching, unexpected. Touch their emotions. We now know that your ability to remember something is largely dependent on its emotional content.

You remember what you care about. You remember when you feel something. If you really want to learn, and you want to learn more quickly and more deeply, pay attention to how you pay attention. Think about how you think. Learn how you learn. Most of us did not take courses on metacognition or learning theory when we were growing up. We were expected to learn, but rarely taught to learn.

If you want to use what you read in this book, you need to remember what you read. To get the most from this book, or any book or learning experience, take responsibility for your brain. Your brain on this content.

As important as a tiger. So just how DO you get your brain to treat networking like it was a hungry tiger? The slow way is about sheer repetition. You obviously know that you are able to learn and remember even the dullest of topics if you keep pounding the same thing into your brain. For example, studies show that putting words within the pictures they describe as opposed to somewhere else in the page, like a caption or in the body text causes your brain to try to makes sense of how the words and picture relate, and this causes more neurons to fire.

On the other hand, if the writing style is formal and dry, your brain perceives it the same way you experience being lectured to while sitting in a roomful of passive attendees. No need to stay awake. But pictures and conversational style are just the beginning… Download at Boykma.

We used pictures, because your brain is tuned for visuals, not text. And when text and pictures work together, we embedded the text in the pictures because your brain works more effectively when the text is within the thing the text refers to, as opposed to in a caption or buried in the text somewhere.

We used redundancy, saying the same thing in different ways and with different media types, and multiple senses, to increase the chance that the content gets coded into more than one area of your brain. We used concepts and pictures in unexpected ways because your brain is tuned for novelty, and we used pictures and ideas with at least some emotional content, because your brain is tuned to pay attention to the biochemistry of emotions.

That which causes you to feel something is more likely to be remembered, even if that feeling is nothing more than a little humor, surprise, or interest. We included more than 80 activities, because your brain is tuned to learn and remember more when you do things than when you read about things.

We used multiple learning styles, because you might prefer step-by-step procedures, while someone else wants to understand the big picture first, and someone else just wants to see an example.

But regardless of your own learning preference, everyone benefits from seeing the same content represented in multiple ways. We include content for both sides of your brain, because the more of your brain you engage, the more likely you are to learn and remember, and the longer you can stay focused. Since working one side of the brain often means giving the other side a chance to rest, you can be more productive at learning for a longer period of time.

We used people. In stories, examples, pictures, etc. And your brain pays more attention to people than it does to things. Boop Hey, I hear you! Electrons live and active round here. Boop The tracer, or tone-detector. The rest is up to you. Try new things. Lots of it. Your brain works best in a nice bath of fluid. Dehydration which can happen before you ever feel thirsty decreases cognitive function. Networking is a skill, and the only way to get good at it is to practice.

But try to solve the problem before you look at the solution. And definitely get it working before you move on to the next part of the book. Your brain needs to know that this matters. Get involved with the stories. Make up your own captions for the photos. Groaning over a bad joke is still better than feeling nothing at all.

Pay attention to whether your brain is getting overloaded. Out loud. Speaking activates a different part of the brain. Better still, try to explain it out loud to someone else. Or at least the last challenging thing.

Part of the learning especially the transfer to long-term memory happens after you put the book down. Your brain needs time on its own, to do more processing. If you put in something new during that processing time, some of what you just learned will be lost. Cut this out and stick iton your refrigerator. Write your own notes.

We put them in, but if we did them for you, that would be like having someone else do your workouts for you. Use a pencil. Stop and think. Imagine that someone really is asking the question. The more deeply you force your brain to think, the better chance you have of learning and remembering. Slow down. The more you understand, the less you have to memorize.

We begin by teaching basic concepts like cabling and physical layout, then we move on to signals and hardware, and then onto stuff like wireless networking, security, and network design. So we begin by having you physically layout simple networks and work with network cables.

Then, a bit later in the book, we show you good network design practices. We intentionally cover things differently than the other networking books out there. Trust us. We like it when our students stay awake in class. The redundancy is intentional and important. One distinct difference in a Head First book is that we want you to really get it. We love it when you can find fun and useful extra stuff on book companion sites. For some of them, there is no right answer, and for others, part of the learning experience of the Brain Power activities is for you to decide if and when your answers are right.

In some of the Brain Power exercises, you will find hints to point you in the right direction. He enjoys skiing and horseback riding with his family in the mountains of western Montana. Rohn Wood lives and works in Montana trying to bring high performance computing to the old West.

A full time employee of the University of Montana and half-time employee of the University of Washington, he makes his living off his UNIX chops and works remotely from his home in the Bitterroot Mountains with a view down into the valley a few miles from Travelers Rest where Lewis and Clark laid over with Corps of Discovery two hundred years ago. Technical Reviewers: Thanks to our editor, Brett McLaughlin, who dove into this project when he had a massive load of other things to do.

Brett, you are a juggernaut of production! Ryan would especially like to mention that his sessions with Brett and Al kept him going during a difficult life transition. Thanks, guys! Thanks to Dawn Griffiths for the excellent and magical work she did to shape this book up and make it look beautiful. Thanks also to the Head First folks we met in Boston, especially our brothers and sisters-in-arms: We will never forget the day we discovered the Head First series at the bookstore.

Thanks to Kathy Sierra and Bert Bates for lighting up the neurons of geeks everywhere. Without Emily, my wife, I would have not been able to write this book.

She took care of business while I hunkered down in the den all those countless weekends and evenings. I love you honey! I love you guys too! Finally, my faithful dog CC, she was always with me in the den, sleeping of course. Thank you to my daughter, Josefina, and my son, Vincenzo, who love books as much as I do. Thanks to my sweetie, Shonna Sims, who believed in me just when I was about to give up on this book.

Tracee Jamison, Yumi Hooks, Dr. Paul Hansen without whom I never would have gotten into technology in the first place. Thanks to the IT students of Salish Kootenai College, without whom we would never have been inspired to write this book in the first place.

Their service is proving popular with tourists and locals alike. Coconut Airways depends on their flight booking system. Coconut Airways needs to get their network up and running again, and fast. Think you can help them out? What sort of problems do you see? Circle each one. The booking system network cable is busted It looks like a break in the flight booking network cable is giving the Coconut Airways staff network errors.

If we can fix the network cable, that should get rid of the messages, and Coconut Airways will be able to book passengers on their flights again. So how do you think we should fix the network cable? All ofthe weight of the cablesresting on one anothermight cause problems in thelong run. Put your fiber optic devices closer to wherethe cables come in to therack.

In this case, thetop of the rack would be best. Gravity and a little nudge could drop your power. Bind your cables and run them along a stable surface. That way you reduce tangling, snags, and confusion. Label your devices on the front and the back. Which cable goes where? Label your wires so that you can troubleshoot problems more efficiently. Check your connectors and ports regularly. You never know when a connector will pop, especially when you have dangling cables. There are two key things we need to do in order to mend the cable and get the flight booking system up and running again.

We need to cut out the broken part of the cable. By cutting out the broken part of the cable, we lose the connector on the end. So what sort of cable are we dealing with here?

What sorts of network cables do you already know about? How do you think they are different from one another? The jacket and the wires inside appear to have been chewed. RJ connector Download at Boykma. It has two distinguishing features. First of all, it has an unshielded twisted pair cable or UTP cable.

Secondly, it takes an RJ connector on either end. Most Ethernet networks run on CAT-5 cables. CAT-5 cables have print on the outside giving you important information about the cable. As an example, you can look on the outside of the cable to see what type it is, what the speed is, and any relevant standards. This is an RJ connector. It allows you to plug your cable into places. Writing on the outside ofthe cable tells you usefulinformation such as the speed. One pair is brown, another pair is blue, another pair is green, and the final pair is orange.

Each pair consists of one plain and one striped wire. So why are the pairs twisted? This means that you can get electromagnetic interference and crosstalk— both of which are bad for your network data. When the wires are twisted, the magnetic field around the wire is effectively disrupted so that any interference is reduced.

The more twists there are in the pairs, the better. This is the outer jacket of the UTP cable. There are four colored, twisted pairs of wire. The colors are brown, blue, green and orange. Each pair consists of a plain and striped wire of the same color. In this pair, one of the wires is plain orange, and the other has orange and white stripes.

See, being twisted can be a good thing Each color has a specific meaning, and so does the solidity of the color. The color solidity shows the wire polarity. If a wire is striped, then this means that it is positive.

If a wire is solid, then the wire is negative. Orange and green wires send and receive data. The orange pair sends data, while the green pair receives data. Blue and brown wires are reserved for future bandwidth capacity. The cable standards folks designed CAT-5 with the extra colored wires so that they could be used for higher bandwidths in the future.

The green pair receives data Striped wires are positive, and solid wires are negative. Solid wires are negative. Network speed tells us the rate at which data can move on a wire. Bandwidth is a capacity; speed is a rate.

Bandwidth tells you the maximum amount of data that your network can transmit. Speed tells you the rate at which the data can travel. The speed of a CAT-5 cable changes depending on conditions. What is Base-T? Base-T refers to the different standards for Ethernet transmission rates. The 10 Base-T standard transfers data at 10 megabits per second Mbps. The Base-T standard transfers data at Mbps. The Base-T standard transfers data at a massive Mbps.

Megabits per second Mbps is a bandwidth rate used in the telecommunications and computer networking field. One megabit equals one million bursts of electrical current aka binary pulses. Megabytes per second MBps is a data transfer rate used in computing. One megabyte equals 1, , bytes, and one byte equals 8 binary digits aka bits. All you need is a pair of wire cutters, a utility knife, a crimping tool, and an RJ connector. Cut the broken part out. Cut the cable well before the break to ensure that you have a good set of wire ends.

Make the cut as straight as possible so that the individual wires are the same length.

Untwist the wires so that you can line them up with the slots on the RJ connector. Each wire fits into a slot in the RJ connector. Are you trying to get me electrocuted or something? How do I know which position each wire goes in?

Do you expect me to just guess??? Where you put each wire is important. It allows you to plug your cable into a wall jack or the network port of a network device like a computer. Each wire in the cable goes into a slot inside the RJ connector, and this connects it to a pin in the connector. Each wire in the cable goes into a slot in the RJ connector. This fixes the wire to a pin in the connector.

So which wire goes where? The position of each wire is important. When you plug an RJ connector into a jack, the pins on the connector make contact with pins in the jack. If the wires are in the correct position, this allows information, in the form of electrons, to flow.

The order of the wires in an RJ connector conforms to one of two standards. These standards are A and B. Striped green, solid green, striped orange, solid blue, striped blue, solid orange, striped brown, solid brown. Can you see any similarities between the A and B wire orders? The order for each standard is basically the same except the orange and green wires are switched over.

So which standard should you use? When you attach an RJ connector, the key thing is that both ends of the cable use the same standard. Before fitting a new RJ connector, take a look at the other end of the cable. If the other end of the cable uses standard A for the RJ wire order, then fit your new RJ connector using the A standard. If it uses B, then use this standard instead. Striped orange, solid orange, striped green, solid blue, striped blue, solid green, striped brown, solid brown.

Striped wires alternate with solid colored wires. The B wire order is like the A wire order but with the position of the green and orange wires switched around. What should the wire order be on the other end? Draw a line between each wire and its rightful slot. Normally, he could jump on his favorite search engine to find the pin and wire color arrangement, but the storm has taken out his connection to the Internet. What can he do? Suddenly, Jack has an idea and leaves the room armed with a pair of scissors.

How did Jack solve the problem without looking up Standard B? Five Minute Mystery Download at Boykma. The good end of the broken Coconut Airways network cable has an RJ connector wired up using standard B. Both ends of the cable need to follow the same wiring standard, so make a note of what the other end uses. Once the lines are in their proper slots, place the RJ into the crimping tool, and then squeeze the tool to crimp the RJ snugly onto the cable. Check the end of the RJ connector to ensure that the wire is seated correctly in each slot.

Five Minute Mystery Solved Q: Through common use, we have come to call an 8P8C connector an RJ connector. The acronym 8P8C stands for 8 positions, 8 contacts. The RJ connector looks a lot like an 8P8C connector, so over time, many folks mislabeled the connector.
