What does this phrase mean? "There are only 10 types of people in the world; those that understand binary, and those that don't.

Hello,

In binary numbers, the decimal number 2 is written as 10. So when you understand binary, you can read it as "there are only two types of people in the world, those that understand binary and those that don't".

Here's a brief description of how binary numbers work:

In decimal number, we have 10 numbers, 0-9. To count to 10 in decimal, we place a 1 in the "ten's place" to represent 10 1's. To count to 100 we place a 1 in the "hundred's place" to represent 100 1s. Each "place" is 10 times greater than the previous one, the 10's place, the 10x10's place (100's place), the 10x10x10's place (1000's place).

Clear so far, right?

In binary numbers, there are only 2 numbers, 0 and 1. To count higher than 1 we put a 1 in the "two's place" to represent 2 1s. To count higher than 3 we place a 1 in the 4's place. To count higher than 7 we place a 1 in the 8's place. Etc. So we have the 2's place, the 2x2's place (4's place), the 2x2x2's place (8's place), the 2x2x2x2's place (16's place) etc.

Here is how we count in binary, with the decimal equivalent:

0 = 0
1 = 1
10 =2
11 =3
100 =4
101 =5
110 =6
111 =7
1000 =8
1001 =9
1010 =10

I love the question... too funny.

And to carry the binary thing a little farther into the realm of Networking...

TCP/IP addresses are a set of four 8-bit binary numbers with the ranges of 00000000.00000000.00000000.00000000 to 11111111.11111111.11111111.11111111.

To convert this to base 10, that would be 000.000.000.000 to 255.255.255.255.

Aww, if you're going to go into binary for IP addressing, I prefer to just use CIDR for my subnets. /32 is a lot easier than 11111111.11111111.11111111.11111111

:)

Here's something I observed:
There are 10 types of people on this planet: those that know trinary, those that don't & those that may know (or not).

No need to get into much details or think much.
Here binary goes into either 1 or 0.
So it means to say that there are only 2 type of people.
Here 10 means 2 types one is number 1 & second is 2.
10 goes for 2 very simple.

To understand the phrase, you need to understand binary numbers. When you understand binary numbers, the phrase is immediately understood. (Hint, in binary, 10 is not "ten".) Therefore: Binary - Wikipedia, the free encyclopedia
