Hi Guys,

I'm trying to find some Study material online I can download to learn Binary Maths for the CCNA+CCNP I'm doing in January. Anyone know of a good Study guide or Course material for this? Pref some "freeware" :p I can download somewhere.

Would be greatly appreciated.

*I know it's not a must have for CCNA but I would love to have it under my knees before I start Cisco.

I had to teach myself, binary maths this year. I did it for an advantage at the college and for my international exams:D

In the CCNA manuals their are usually basic examples to work through.
Try the following links:

http://www.math.grin.edu/~rebelsky/Courses/152/97F/Readings/student-binary
http://www.binarymath.info/

Once you get the hang of it, its actually pretty simple.

PS you could always pay for me to come and teach it to you:D

I found "Bryant Advantage Ultimate CCNA Study Package" Online :eek:. It's in .rar so I'll extract it at home. I don't know if it covers Binary Maths to a degree where I actually understand it and don't need to memorise it. Would love to have a full understanding instead of memorising the damn things.

I'll check your links out, thanx mate :)

Advice try getting the latest version of Sybex CCNA Study Guide, its actually a very good book.

PS if you understand you don't need to summarise it, ever!

But it's sooooo easy! 1 + 1 = 10 :p

This is what I want to get at :)

I'll try and find the Sybex one also then. No torrents at work so I might need to do some old school googeling for a bit to find that as "Freeware" :D

Don't start :D

Do you have any idea how hard it is for me to shift from Standard Finance maths to this? I studied finance ffs. It's like taking everything you know and erase it from your brain and start over from scratch. I see an equation my mind tells me the normal maths answer :D

The trick I found was to not think of binary as maths at all. Just learn it as another language otherwise your fin maths and "logic" will bend your mind to breaking point.

Argh argh, me matees. :p

Everything you need is on Wikipedia..

Read up on
1) Radix
2) Binary numeral system
3) Signed number representations
4) Bitwise operation

And that's about all.

Anything you don't understand, you can ask on the forum, and you'll get very comprehensive answers :)

It's just regular maths!

Most people use Base-10 i.e. the numbers 0 - 9 and then we carry a value when the amount overflows (i.e. becomes more than 1 digit can represent). Same thing happens in Binary (Base-2), Hex (Base-16), Octal(Base-8), etc

Just imagine what would have happened had we evolved with 8 digits (fingers and thumbs) like in the Simpsons? The Decimal system would seem so weird!

ROFL...

If you work in other base systems as much as I do, you'd already think the decimal system is weird :cool:

Seriously though, Base-10 is great for the masses, but most things in nature don't occur in 10's :(

Think is this.

I'm trying to understand this Binary code+Maths instead of just trying to focus on the maths part first. That is the problem I think I'm having. I'll be hoenst I haven't started on it as yet. Will do it tonight and maybe have a better grip on it by tomorrow :D

See! Confusing. :confused:

I see, but what I'm trying to tell you is that Binary is just another way of counting...

Instead of counting in single digits from 0 to 9, you now count in single digits from 0 to 1. All the mathematical principles you've ever learnt still apply; you just have a different basis for the numbers.

So since 2 (binary 10) + 2 (binary 10) = 4 (binary 100), you can see that the same "remainder + carry" principle applies; i.e. 2 binary digits is not enough to hold the value 4, so you need more digits.

Put another way, in Base-10, counting from the right (the least significant digit), each digit has a weight corresponding to the base. All the way on the right, the weight is 10^0, next one is 10^1, then 10^2, etc... When we represent a Base-10 number, we're just saying "how many of these occur in this value?". Same with binary, except now we have 2^0, 2^1, 2^2, etc...

Lol... There are 10 kinds of people in this world... Those that understand binary and those that don't :rolleyes:

Lucky for me I am one of those that does understand. :p But the number of times I see peoples eyes glaze over when you start talking different base number sets. I mean it's not rocket surgery it's brain science.
