Great videos! I'm just doing a quick refresher before I sit the ITF+, and I found your videos a great supplement to my Sybex textbook. It's great that you're giving back to the community. We should all take inspiration and try to pay it forward like this.

You are a natural and wonderful teacher! Ive been looking for almost a year where to start with my Information Technology journey and finally landed on the ITF certificate and so far the two videos Ive watched helpedme with the little information of getting to know what IT is. Thank you and god bless!!

Thank you Tech Gee, this playlist is exactly what I needed to have on in the background during my workday, before I come to study after hours.

I booked the CompTIA ITF+ on 29th December, I watch your videos and they are very insightful and very well explained, thank you!

[DR-ygvo]

TechGee, thank you!!! None of the classes I took and checked out before, explained and did go in detail like you I am sure with the understanding I got now, I will pass my A+

Not to be nit-picky (sometimes my OCD gets the best of me), but at 10:27 you have your G and B mixed up.
RGB is the color spectrum abbreviation from highest wavelength to lowest (Red, Green, Blue).
RBG is Ruth Bader Ginsburg.

Thank you so much for taking the time to put these videos together for us. I just subscribed to your channel. You explained everything very well! I’m new to IT and your videos really helped me to understand this stuff without wrecking my brain!

22:17 Data can also be transformed, right?

*IP* = Internet Protocol
IPv4: 4 bytes = 32 bits
IPv6: 8 group of 16 bits (4 hexadecimal digits) = 128 bits

*Data representation* allows store, transmite and display data.
- ASCII = American Standard Code Information Interchange
- ANSI = American National Standards Institute
ASCII is a standard for encoding characters.
ANSI extends ASCII
Unicode replace ASCII and ANSI
- ASCII: 128 chars
- ANSI: 255 chars
- Unicode: 578 chars

*Code page* is a selection of characters mapped to codes for a specific language.

Code page example: Window-1252

Thank you for the resources! I have a question.
Why (9:45) is "129" on the chart represented as 129 in both decimal and binary format? Is 129 not

[kelleymiddleton]

Is there a book that you recommend that can go along with your course?

[alialbar]

hello, i have two question, is watching your video instead of reading the book is enough to pass the exam?, and should I follow your videos in order? because it's not the same order in the book. thank you

[rebepomales]

Love your videos....BUT 7.4% in decimal is 0.074 NOT 0.0074...decimal point moves two spaces to the left.

[dongordito]

Did you make a video recommending a book that we can use to study?

[thespear]

I think Unicode will add the Bitcoin symbol sometime this decade!
