Convert Hex to Decimal in under 30 Seconds!

This course is geared for Cisco's, CCNA (200-125) certification exam.

Instructed by Lazaro (Laz) Diaz

  • Once you finish the course you will feel comfortable, not only converting numbers, but also in your understanding and comprehension when working with hex numbers.
  • With the introduction of IPv6 we really need to understand how to work in hexadecimal format and be able to convert to decimal if needed. The understanding of conversions is key to any networking professional.

 This course is over 60 minutes long and will give you the knowledge and understanding of how to convert hex to decimal, decimal to hex and binary to hex or decimal.                                                                                                                        

You will become familiar with the format of hexadecimal numbers, their use and their bit values. This course is mostly lecture based using a whiteboard. This method will make you feel like you are sitting in a classroom environment.

Handouts will be available for students to facilitate

learning and practice.

This course will help you in becoming comfortable with, not only conversions, but it will also help you in preparing for the CCNA certification and Computer Science Degrees; not to mention the fact that for those that are already working in the field, it will help you in calculating the conversions without a calculator. This method should expedite the way you convert in order to make you faster, better and stronger.

(Please always check the ANNOUNCEMENTS section for new updates and events, since I am always letting you guys know of my newest and latest endeavors!)


  • The desire to master conversions such as binary to hex, binary to decimal, decimal to hex, decimal to binary, hex to binary & hex to decimal.
  • This course is intended for those that are seeking a career in Networking, Computer Science and other Information Technology fields to include those that are taking certification courses like the CCNA and/or CCNP.

Lazaro (Laz) Diaz,

If you are tired of the same old methods of learning and want someone that is pretty much unconventional, but at the same time will provide you with an enjoyable learning experience in layman's terms...then please preview my courses and you will discover that I am your guy. I am a Network Engineer with many years in the field and in the teaching industry. I hold the following certifications: CCNA, CCNA Security, CCNA Voice, CCNP, Security+, Network+, A+, MCP, MCTS & MOS. My teaching experience stems from teaching at various institutions in the US. Now, I bring the classroom to you! I've taught over 100K students worldwide...courtesy of the internet. Thank goodness for technology! ;-) Having been in all sides of the spectrum; as a student, a teacher/trainer, and in the field, I believe this uniquely qualifies me to understand you, the student. I know first hand what you have been exposed to as opposed to what you really want to accomplish. These two are sometimes extremely conflicting and frustrating. That is why I teach in the manner I do and can relate to your rejection of the Status Quo. I have taught corporate employees at MetroPCS (now T-Mobile) and have also taught IT professionals of companies like The Florida Marlins, Ulysse Nardin, Alberta Water Department (Canada), The Assurant Group, Hospital personnel & Attorney's firms, among others. to guide them in acquiring their IT certifications or general knowledge. However, my expertice also extends to being able to teach applications as well. YES!...I am also an applications instructor and qualified to teach Word, Excel, PowerPoint and Access.This, of course, includes the MOS (Microsoft Office Specialist) certification. As you can see, I am a multifaceted person and consider myself to be an eternal student as well. I teach in an unconventional way that allows for students to understand the subject matter and can therefore, not only prepare them for a Cisco, Microsoft or CompTIA certification exam, but apply my methods in the real world. I strive to give the student a greater opportunity to compete in the current job markets. Do I go above and beyond what is needed for a certification?...YES, I do!...because it's not only about getting a certification, it's also about making sure that you, the student, is prepared for a job interview and/or maintaining your current job by enhancing your skills. This is where I step in and make sure that you are prepared for whatever you need and make you an asset to your employer. Everyone has different requirements and I make sure, or at least I try, to provide information for most scenarios. My classes and/or courses are very simple and that's how I like to teach. I truly believe in "KISS",,,NO, I don't want to kiss you, what this means "keep it simple stupid" - If things are kept simple, easily explained in a way that the student can grasp quickly and retain the information...then I have achieved my goal! For those that do not know me yet, you may not be used to my style of teaching, but you will soon get accustomed to it :)... I'm very laid back, I try to make learning fun and I teach in layman's terms...no physics jargon or mumbo jumbo in my teachings. My courses are very interactive and extremely dynamic!...you will not find my lectures monotone or boring, because falling asleep, for lack of excitement, is just NOT an option. Just take a look for yourself at my video previews, which I always provide on ALL my courses, so you can determine if I'm the right guy to help you get your industry specific certifications. ;) I certainly hope that after a careful review of my credentials & testimonials (you can Google it you know!), I'm the Cisco, Microsoft or CompTIA Instructor you're looking for!
