[orly?]

does anyone know a good way to learn binary?
i think i pretty much covered hexadecimal > decimal
decimal > hexadecimal
but i need to learn how to hexa>binary binary>hexa deci>binary binary>deci
tnx

is this the preliminary or HSC course?, if it's the HSC course I don't think you need to know that stuff.

Binary is not in the IPT HSC. SDD yes, but not IPT.

orly? - check out the Resource Section on this website for worked examples and explanations to help you out. You might want to check the SDD Option - Software Developer's View of Hardware for some help.

gee wm_abusef .. then you would have been surprised with a multiple choice question a couple of years ago in the HSC

orly try this to learn binary

2^5 2^4 2^3 2^2 2^1 2^0
= 32 16 8 4 2 1

so the far right numeral when creating binary changes every time
the second numeral from the right changes every second time
the third numeral ........................................ every fourth time
the fourth numeral ..................................... every eighth time

00000000 = 0
00000001 = 1
00000010 = 2
00000011 = 3
00000100 = 4
00000101 = 5
00000110 = 6
00000111 = 7
00001000 = 8

can you see the pattern ?

binary conversion as described by orly is not in the IPT syllabus.

the mutiple choice questions you describe as involving binary are basic binary involved with error checking and communication - not programming or coding as orly has described.

its not ???
gee then why do we all teach it in the IPT preliminary course and do some form of revision for it in HSC ??

and basic binary or not .. if you had an idea about binary solving that multiple choice question was so much easier.
