Computer Olympiad - Binary Numbers and Operators AND, OR, XOR, and NOT

Change the decimal to binary

For example change the number 40 into binary number

Power of two closest to 40 is 32 plus 8,
32 = 2 ^ 5
8 = 2 ^ 3
So on the order of 5 and 2 1 rated

7 6 5 4 3 2 1 0 ~ 1 byte = 8 bits
-----
0 0 1 0 1 0 0 0

So the number 40 in binary is 0 0 1 0 1 0 0 0

Change the binary number to decimal

Change 0 0 1 0 1 0 0 0 to decimals

7 6 5 4 3 2 1 0
-----
0 0 1 0 1 0 0 0

In the fifth and third order valued at 1, so
(2 ^ 5) + (2 ^ 3) = 32 +8 = 40

OR Operation

If there is one that is worth 1, the result is a
Example: 40 OR 7

7 6 5 4 3 2 1 0
-----
0 0 1 0 1 0 0 0
0 0 0 0 0 1 1 1
-----
0 0 1 0 1 1 1 1 = 47

XOR Operation

If there is one that is worth 1, the result is one, if both are worth one or 0 then the result is 0
Example: 40 XOR 8

7 6 5 4 3 2 1 0
-----
1 0 0 1 0 0 0 0
0 0 0 0 1 0 0 0
-----
0 0 1 0 0 0 0 0 = 32

INTERNATIONAL Operations

If both a valuable one, the result is a
Example: 40 AND 8

7 6 5 4 3 2 1 0
-----
0 0 1 0 1 0 0 0
0 0 0 0 1 0 0 0
-----
0 0 0 0 1 0 0 0 = 8

NOT operation

Contrary to the previous value
Example: NOT 20

Seven six 5 4 3 2 1 0
-----
0 0 0 1 0 1 0 0
-----
1 1 1 0 1 0 1 1 = 235

I go and have studied a binary operation at Skul
CPE lesson time fitting material fits Microprocessor logic IC (integrated circuit)
IC with logic AND, OR, XOR, and NOT, is in IC 7400 series
has long learned not to be forgotten .. uh, now remembered again
