Network Communication in life<Chapter 0 – Introduction>
Why writing this book
I like learning and I'm a visualization style person in learning, I strongly prefer knowledge to be expressed and learnt in a casual way of games, examples or stories. When I was in secondary school or university, I was frustrated about the way instructors spreading out knowledge – for us, they were just pieces of information – or memento, those may easily lost their value after exam of end of the course. If you are lucky, you may still recall some of those from your family background, career or friends, but not all.
This book is written for those who were afraid of computing networking, but amazed by or curious of how general network communication works – how we get connected and connected so closely. It's also suitable for those with zero knowledge background in networking. This book is not meant to go deep into the technology side, it's not an introduction to the technology, it's simply a story book telling networking concepts from our real life examples, a 'pre-school' book for the network communication.
About the author
I've graduated with a Bachelor degree in Science, major in Mathematics. Now I'm working in a network security company as Network Security Analyst, for Distributed Denial of Service (DDos) detection and prevention.
This is a wish since I stepped my foot into IT field. I'm not a purely IT person, but a document guy, enjoy being the man-in-the-middle helping delivering communications between several parties.
I'm on my track to take the most challenging exam in the industry in computer networking – CCIE R&S (Cisco Certified Internetwork Expert: Routing and Switching track). This book will be completed this year (2009), as a 'supporting' document to the certificate, or to apply for a research master study in information security.
Words from the author
I was the same as many of you when I first heard of network communication – amazed. It's not an easy topic to express by IOS, TCP/IP, BGP… forget about those terms, there's no secret of getting understanding of those jargons, they are just another form of our day-to-day activates, just in another form. Within a year after graduation from university, I've forgotten almost all courses of complex number, differentiate equations… Lady for company administration asked me one day: "I don't know what your company is doing; boss told me we are doing something called DDoS, but I've no idea what is that." I explained and she nodded, I was pleased.
With only my explanation is not sufficient to understand those concepts, at least when you have read it the first time. It's something I can explain how to do that here – it's the sense to life, not just from the surface, you need a little bit more – the concept and logic behind them, keep asking if not sure. I'm not able to understand every field to become a generic 'Doctor of knowledge', learning in a interactive way is also an example of 'network communication in life', please do contact me if you have any question of this book or anything related to this book.
