Computers smart?

I have heard that computers only know the number 1. What's that all about??

The vast majority of computers are binary computers, meaning they use the binary number system. In binary, the only digits are 1 and 0.

1 decimal = 1 binary

2 = 10

3 = 11

4 = 100

(you start counting normally, but you have to carry every time you add a 1 to a 1)

Wrong. It knows 2 numbers.Unlike the decimal system, only two digits - 0, 1 - suffice to represent a number in the binary system. The binary system plays a crucial role in computer science and technology. The first 20 numbers in the binary notation are 1, 10, 11, 100, 101, 110, 111, 1000, 1001, 1010, 1011, 1100, 1101, 1110, 1111, 10000, 10001, 10010, 10011, 10100, the origin of which may be better understood if they are re-written in the following way:

1: 00001 11: 01011

2: 00010 12: 01100

3: 00011 13: 01101

4: 00100 14: 01110

5: 00101 15: 01111

6: 00110 16: 10000

7: 00111 17: 10001

8: 01000 18: 10010

9: 01001 19: 10011

10: 01010 20: 10100
1 and 0 Basically On and Off
There are no smart computers, only smart programmers.

And not all programmers are smart. I should know, I are one. :-)
Computers do everything based in binary which is combinations of 1's and 0's.
