Binary help?

[iBlueBox]

We where doing an introduction to Binary today in ICT. I didn't really get my head around how it works,

Can someone explain to me?

also,

What's hexonigal Binary ( can't remember the exact spelling )

[Pawf]

I don't get why they still continue to make a massive deal out of binary. Except maybe in a computer history lesson lol. The only use I have for it in day-to-day job is piddling around with subnet masks. What is it that you don't get? As long as you have a basic understanding, that'll get you by!

EDIT: This is a good explanation: http://php.about.com/od/programingglossary/qt/binary.htm

[iBlueBox]

Aha I think I'm understanding turning numbers into binary now,

But how do you work out binary to numbers?

[Chippiewill]

16 8 4 2 1
1 1 1 1 1 = 31
0 0 0 0 0 = 0
0 0 0 0 1 = 1
1 0 0 0 0 = 16
1 0 1 0 0 = 20

If there's a one under the number you add it to your base-10 number.

Hexadecimal you don't really need to know, but it's base-16 with digits 0-15 (Base-10 is digits 0-9)

0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 - Base-10
0 1 2 3 4 5 6 7 8 9 A B C D E F - Base-16

So A1 would be 111, F1 would be 151, 160 would be FA etc. bit confusing because our minds are trained to think in base-10, it's like trying to perceive a fourth dimension -- way easier to percieve the first, second and third dimension.

16 8 4 2 1
1 1 1 1 1 = 31
0 0 0 0 0 = 0
0 0 0 0 1 = 1
1 0 0 0 0 = 16
1 0 1 0 0 = 20



So what if you wanted 32 for example?

[CrazyLemurs]

In that example, you would have to move into the next column. It's like going up in 10s in the decimal system.
9 becomes 10 (adding an extra digit), just like in binary, 11111 becomes 100000.
11111 is 16+8+4+2+1, but 100000 is 32. Sometimes when binary is given in a textbook, it will say up to 127 or 255. These are the limits of 8 and 9-digit binary numbers.

[Chippiewill]

Either you genuinely don't know (Somehow) or you're trolling me.

You just extend the table left adding 32 as an option, you can keep adding multiples of 2 all you like.

[CrazyLemurs]

Just to note, I've just started the new-ish Computing GCSE, and part of the syllabus is understanding binary. It's really quite important in that field. It is also useful in I.T., for different reasons.

[Zak]

So what if you wanted 32 for example?

32 |16 | 8 | 4 | 2 | 1 |
1 | 0 | 0 | 0 | 0 | 0

but you know that :P
**** formatting!!!

I legit didn't know, but now you say that, I realise how much of an idiot I was. LMAO.

I don't deal with this rubbish on a daily basis!

lol, and you say David wouldn't be able to handle linux?

[HotelUser]

Just pointing out first what happened to the binary game in the Tech section??


lol, and you say David wouldn't be able to handle linux?

He did but I think partly because of an inside joke regarding GoDaddy (curse you Tom and Matt!!).

In all honesty it's not a matter of being able to "handle" linux (in which case I do know my way around a Ubuntu or Debian terminal to do the basics - I run a headless Ubuntu box for a few things here at home) but someone like Tom or others on the forum are just very much so more knowledgable and experienced with Linux and managing a server on Linux than I am. I haven't spoken to Jin about root access to the server if he feels comfortable giving that out to anyone I presume he will. If, for instance Matt or I did have such access I feel confident we would make do because we would have Tom here who's experienced enough to help, and easy enough for us both to inslave :)

What! I politely disagree Tom :P

Nub LOL. It's just the simplest possible number system; base 2. We work in base 10 in normal life. Hexdecimal is base 16. The only reason we use base 10 is because we have 10 fingers/thumbs. If we had 8 then we'd probably be using the base 8 number system (called octal).

I don't get how Recursion can appear so smart especially on the technology side of things and not know something as easy as binary???

I am smart :(!

I know you are :P that's why I was like omg, as if a dumb person like myself knows something you don't. :P You're like a technology genius!

It's just counting. But simpler!

[Chippiewill]

Linux is easy, Maths is blehhhhhhhhhhhhh!

I hate to break it to you but computers are based on maths. glhf at uni.

Besides.. maths is awesome.

Nah, I think he just pretends he knows a lot so he can keep winging about server downtime.

What's a Lunix? ;)

Also I said Maths is blehhhhhhh, not that I wouldn't do it! :P

[Chippiewill]

It's a freebsd variant made by Lunis Tarvolds

How dare you speak about maths like that :'(
