Networking
   Networking is the word people use when they're talking about connecting computers together so they can share data with each other and all connect to the internet at the same time. Let's take a closer look at the key components that make up a simple easy to set up network. Think of a network is something similar to your body central nervous system. At the top of the network is a brain that handles all the traffic coming through. This is called a router.
    The brain is connected to a spine that send signals throughout your network. This device is called a switch and it distributes signals to all of your computers and devices via network cables. Now let's check out each of the components of a wired network and more detail.
   We'll start with the router. A router has a smart little computer inside that identifies all of the computers and devices on your network and assigns a unique number to each one.
   Techie people call this an IP address. A router also connects to the internet outside your home via a modem that can be provided by your dsl or cable internet provider. A router is always at work. Managing the tons and tons of information your computers and devices send and receive and controlling which computers and devices get what information and when so how does a router actually send information from the internet to your computers and devices and how does it enable your computers to share information with each other.
   The answer lies with that device we mentioned earlier a switch. A switch sins traffic through your network to the places it needs to go. Every netgear home router has a switch with four ports built right into it you can also get wireless routers from netgear that use radio signals to do. The same thing as a switch but these still have those four ports built into them so you can use wires. With them too when you're buying a router for use in a wired.
   Network pay attention to the speed of the built-in switch the fastest switches are called gigabit and they're perfect for applications like streaming video in your home meanwhile routers switches called fast ethernet are great for essential tasks like web surfing email and online gaming now say you have more than four idea as you'd like to plug into. A router you need more ports the solution is easy you'll need an additional switch which again is that thing that's already built into your router in this case though you just need to switch portion and not another router. Because your network doesn't need two brains after all netgear has switches with as few as five ports as well as some that feature ports or more once again.

    If you need the fastest speeds go for a gigabit switch your smarty pants net gear router will recognize. These new connections and start sending data to them right away here's one more thing to keep in mind some people often confuse a switch with a related device called a hub. Which is obsolete you just need to know that hubs were replaced by switches. Because switches do the same thing but with a lot more speed and smarts a router a switch and network cables all come together to create a fast and reliable wired network. That works a lot like your body's nervous system fortunately you don't have to be super brainy to understand how it all works.

Tech Trends
Top Tech Trends 2016
   In my role technology distribution can it’s important to love five years out to see what industry is headed in the long term but much of my attention is focused on the near future identifying the technology and trends that are ready to be put to use a tablet over the next 12 months. With that in mind her for the top IT trends that I believe a poised to gain real traction in 2016.
   My number for trend is the software-defined data center. From the beginning data centers will be made up of silos of servers storage and networking hard way but that model is redundant and expensive and it makes it difficult to allocate resources quickly. That’s a problem for IT teams that are feeling pressure to improve responsiveness and decrease maintenance costs. In a software-defined data center all the essential elements of a computing platform a pool together virtualized and managed to a common set of application programming interfaces. With all of the data centers resources pulled together it’s easier and faster to monitor and reallocate computer storage network in and even security resources according to the needs of the business.
    Production-ready software-defined data center offerings and now available from established vendors vendors as well as from new cameras and I tea shops are looking for safe and proven ways to movie to a software-defined-environment. That delivers the stability and the agility that their businesses require. My number three top trend is what I call a mobile first approach until now most mobility initiatives will focus on providing mobile devices with the same access and security that we find on desktop and laptop PCs. The mobile versus approach turns out world view on its head.
   It’s not about matching the PC experience and a small device anymore. It’s about getting the most of the unique advantages that mobile platforms have to offer. Such as the ability to easily capture pictures documents and also knowing the precise location of device as mobile devices get more convenient security with a broader adoption of biometrics.
   I expect more businesses will be thinking mobile-first in 2016 for both customers and employees. My second top IT- tried 4 2016 is machine learning. I see machine learning is a logical evolution of the exponential growth of data and data analytics. That we’ve been seen over the last few year big data and data analytics today are mostly concerned with mine in large quantities of data to provide insights that leaders can use to make informed decisions with speed.
   However those results of focus on helping business leaders interpret past activity. A machine learning on the other hand is about using the same data sets to predict future behavior. Today Google, Facebook and Amazon or relying on machine learning to deliver content ads and products that use your past activity to predict what you’ll be interested in next IBM’s Watson initiative extends its significant machine learning capabilities to IBM customers.
   A machine learning is also at the heart of Google’s efforts to develop self-driving vehicles. As the engineers at Google will tell you it’s easier to drive a car when you can predict what’s around the corner rather than having to focus on the road behind you and running the businesses is no different. That’s why I believe machine learning will be one of this year’s top trends to gain traction as organizations like to predict the future as well as they can analyze the past.
   My top IT trends for 2016 is the internet of things specifically the industrial Internet of things. One study from the mckinsey global institute estimates that IOT will deliver up to 11 trillion dollars of global economic impact on an annual basis just 10 years from now and a significant proportion of that was going to be made up the industrial IOT.
  For example, one of a minute industrial equipment customers has begun in bed in connected sensors into the field based equipment. This gives our customers the ability to let maintenance teams know when a component is about to break down but before it actually happens. This happens this simple warning helps avoid costly downtime and emergency repairs. It also ensures that the service technicians have exactly the right parts they need when than arrive on site.

   2016 will be the year the IOT hits critical mass. The opportunity is simply too large for that but the building blocks for the ecosystem and now in place. Making it easier faster and less expensive to prototype and roll out real world IOT solutions. That’s why it’s my number-one trend for 2016. To find out how these and other top technology trends are being applied inside the enterprise in the year to come. Stay tuned to this text and series and to my blog behind the firewall and don’t forget to give us a thumbs up or post  a comment below this video is a value to you.
Planning the presentation

1. Write note cards on index cards. Write main ideas on your index cards. Don't write details, or be stuck with the fate of looking down, staring at your note cards while reading. Put in some fun facts, interactive questions, and other interactive activities on the cards to share with the class.
·         Write down keywords or main ideas. If you need to consult your index cards, you're only going to want to scan the index card for information, not read every last word.
·         Most of the time, the act of putting information down on your index cards will help you remember the information. So, while you might not strictly need the note cards, it's a nice security blanket to have if you happen to forget what you were going to say.
2. Practice. In most presentations, it is pretty obvious who has practiced and who hasn't. Work on what you're going to say and how you're going to say it. You'll feel a lot more confident when you do the real thing and you'll eliminate the "likes" and "ums" unlike those who try to "wing it."
·         Practice in front of your family or friends, or in front of the mirror, when you rehearse your presentation. It's probably better to do it in front of friends who you may not know well, as this will help you replicate the feeling of being in front of the class.
·         Ask your friends for feedback after you finish your presentation. Was the presentation long enough? How was your eye contact? Did you stammer at all? Were all the points clearly made?
·         Make a critique of your practice performance. Challenge yourself to work on all the things that you believe you can improve during the real presentation. When it comes time to deliver the real deal, you'll feel confident knowing that you've worked extra hard on what was toughest for you.
3. Do your research. In order to give an engaging presentation, you need to know what you're talking about. You don't have to become an expert, or read every book or website ever written about your topic, but you should be able to answer any questions your teacher or classmates might give you.
·         Get quotes from reliable sources. Good quotes make a good presentation great. Taking what smart people have said and putting it into your presentation not only makes you look smart, it shows the teacher that you spent time thinking about what other people said.
·         Make sure your sources are trustworthy. There's nothing that can quite break your confidence like a fact that turns out to not be a fact. Don't always trust the information you get off the Internet
Delivering the presentation
1. Smile at your audience. When it comes time to present, there's nothing that draws your audience into your presentation than a good old fashioned smile. Be happy; you're about to teach your entire class something they didn't know before.
·         Studies have shown that smiles are infectious[1]; that means that once you smile, it's hard for everyone else not to smile. So if you want your presentation to go off without a hitch, force yourself to smile. That'll make everyone smile; and maybe those smiles will make you actually smile.
2. Feel confident about your presentation. When you give your class a presentation, your teacher is essentially having you take over their job for a little while. It's your job to make sure everyone understands what you're trying to tell them. Make sure you pay attention to how your teacher does this before your presentation, because teachers are expert presenters.
·         Visualize success before, during, and after your presentation. Be humble about what you do — no need for cockiness — but imagine a successful presentation at all times. Don't let the thought of failure creep into your mind.
·         In many ways, your confidence is just as important as the information you're delivering. You don't want to spread misinformation, or skimp on doing your research, but a lot of what you'll be graded on — and what the other students come away with — is going to be your level of confidence. Also if you are confident, you will have a better time exchanging ideas with the class.
·         If you need a confidence boost, think big picture. After 10 or 15 minutes, your presentation will be over. What will your presentation matter in the long run? Probably not very much. Try to do the best you can, but if you're getting nervous, remind yourself that there are much more important moments in your life to come.
3. Make eye contact. Nothing is more boring than listening to a presenter who looks at the floor or at note-cards. Relax. Your audience is made up of your friends and you talk to them all the time; talk the same way now.
·         Have the goal of looking at every person in the classroom at least once. That way, everyone will feel like you've engaged with them. Plus, you'll look like you know what you're talking about.
4. Be sure to have inflection in your voice. Your goal is to engage your audience, not put them to sleep. Be animated about your topic. Talk about it as if it was the most interesting thing in the world. Your classmates will thank you for it.
·         Inflection is the kind of movement that radio DJs put into their voice; it's the ramped-up pitch in your voice when it gets excited. You don't want to sound like you've just seen a lion, but you also don't want to sound like you've just seen a squirrel, either. Vary it up to make the presentation more interesting.
5. Use hand motions. Move your hands along as you talk, using them to emphasize points and keep the audience interested. It will also channel your nervous energy into a better place.
6. Have a good conclusion. You've probably heard the presentations that end in something like "um... yeah," Your conclusion is your final impression on your audience, including your teacher. Make it exciting by introducing a final statistic, or come up with something creative to do at the end. Your conclusion can be anything so long as your audience knows you're finished.
·         Tell a story, maybe one with a personal note. Stories are great for history or English presentations. Maybe you can tie your presentation into a little anecdote about a famous historical person?
·         Ask a provocative question. Ending with a question is a good way of getting your audience to think about your presentation in an interesting way. Is there a certain conclusion you want them to come to?
7. Walk back to your seat with a smile. Know that you just aced your report and that you just did something that many people would never be able to do. Don't be disappointed if you don't get applause. Just stay confident.
Tips
·         If you make a mistake, don't worry about it. If you don't draw attention to it by correcting yourself, no one will notice and if they do, they'll quickly forget.
·         Remember: Make your voice loud- or in the acting term, project your voice.
·         Be confident and when you're nearing to the end of your presentation ask the audience if they have any questions or comments. It will make you look mature and let the class know that you really care about the topic.
·         Remember that power point is a tool for your audience, not your script. Your presentation should include much more than you put on the power point and your slides should not have too much text on them.
·         Try to get the right level of formality in your speech, depending on what it is for and who you are presenting it to.
·         Make sure you look around the room, not just in the middle of the room.
·         Have good posture. Don't cross or fold your arms, keep them open. Don't slouch and keep your back straight.
·         Try not to argue with your audience. This detracts from your presentation. Just tell them they have an interesting point and that you'll check and get back to them.
·         Don't forget to look at everyone, not just the floor. Don't stare at anyone in particular but 'skim' the class.
·         Move around! You don't have to stand in one spot the entire time. Have fun with it! Using your body to accentuate your voice can also add a more natural feel to your presentation.
·         Know that everyone watching you is so nervous about their own presentation, they're probably not listening much to yours!
·         Choose a spot in the middle. That way you can watch a few presentations and avoid their mistakes, but your audience isn't too bored by the time it's your turn.
·         Keep your hands below your shoulders so the audience does not get distracted.
·         Blow on your thumb, it can reduce stress and anxiety.
·         If you have a poster, don't read it word by word! Only use the words on the poster as reminders for yourself.
·         Do not stand in the way in the projector, as it will divert the attention to your silhouette and will hinder the details written in your slide.
·         Try to walk around during the presentation, it makes you appear more relaxed and confident.
·         While walking(during the presentation) do not cross from in front of the projector, always go around it.
·         If you are thinking of something other than the presentation, try to turn your thoughts towards something else; otherwise you will get distracted.
·         Make sure to speak very clearly and don't slur your words.
·         You must be very bold while speaking.
·         Keep your chin up, but don't show you neck. People will tend to notice that holding your chin high, but not too high, gives you more of a confident look to yourself.
Warnings
·         Some people may be so tied up before a presentation that they feel faint and may pass out during their speech. If this describes you, make sure you prepare especially hard and keep your blood sugar up before you present.

·         Don't keep your mobile phone in your pocket or it will interfere with the microphone (if any).
