please what's the most simple way to explain binary reading for me to understand; i still don't get it. please help me..

Let me try. :)

Lets take a normal decimal number. Lets say 205. If you take that number apart based on the 10 (decimal) factor you have

100s | 10s | 1s

2  |   0  |  5

Binary is the same thing based on a factor of 2. So your columns look like this:

16s | 8s | 4s | 2s | 1s

Now lets take some numbers so it makes more sense. Basically if you have a decimal number you break it apart from left to right on that scale and if you have a binary number you put it back together from right to left.

Examples:

                                                  16s | 8s | 4s | 2s | 1s
                                                   ----------------------

decimal number: 3 | 1 | 1 (3 = 4s*0 + 2s*1 + 1s*1) decimal number: 7 | 1 | 1 | 1 (7 = 8s*0 + 4s*1 + 2s*1 + 1s*1) decimal number: 13 1 | 1 | 0 | 1 (13 = 16s*0 + 8s*1 + 4s*1 + 2s*0 + 1s*1)

Think of it in a yes = 1 and no = 0 way (that's the way the computer thinks):

Can you fit 16 into 13? no / 0 Can you fit 8 into 13? yes / 1 (now you subtract 8 from 13. The rest is 5) Can you fit 4 into 5? yes / 1 (now you subtract 4 from 5. The rest is 1) Can you fit 2 into 1? no / 0 (no need to subtract anything since it doesn't work) Can you fit 1 into 1? yes / 1 (now you subtract 1 from 1. The rest is 0. Full stop)

Does that make sense?

If you want to put a binary number together you do the exact opposite: (Bin number 11001). Start at the right side.

Is there a 1 in your number? Yes / 1 (Remember: 1) Is there a 2 in your number? No / 0 Is there a 4 in your number? No / 0 Is there an 8 in your number? Yes / 1 (8+1 = 9) Is there a 16 in your number? Yes / 1 (16 + 9 = 25)

I hope that helps. Here is another great article (although a little dry for my taste): http://www.math.grin.edu/~rebelsky/Courses/152/97F/Readings/student-binary#1011-a

Have you watched the Binary video that is part of the Digital Literacy - Computer Basics course?

I thought that it does quite a good job of explaining it.
