1
00:00:01,000 --> 00:00:07,410
Now as part of this course you'll have access to a binary decimal and hexadecimal converter that we've

2
00:00:07,410 --> 00:00:10,470
created to make this very easy.

3
00:00:10,470 --> 00:00:19,990
So a decimal IP address of 255 255 255 255 converts to binary numbers consisting of four groups of eight

4
00:00:19,990 --> 00:00:25,190
binary ones and eight hexadecimal F's as discussed.

5
00:00:25,280 --> 00:00:27,450
Now an inverse mosque is also shown here.

6
00:00:27,610 --> 00:00:38,590
So if you inverse the number 255 in decimal equates to zero in decimal inverse binary is a zero inverse

7
00:00:38,590 --> 00:00:40,420
hexadecimal is a zero.

8
00:00:41,740 --> 00:00:54,000
Let's do an example of 240 1 to 3 and convert that he has your binary number.

9
00:00:54,190 --> 00:00:56,210
Is your hexadecimal number.

10
00:00:56,210 --> 00:00:57,560
He has the inverse.

11
00:00:57,740 --> 00:01:00,410
So the inverse is based on the binary.

12
00:01:00,410 --> 00:01:03,320
Notice these four binary values are a 1.

13
00:01:03,410 --> 00:01:10,150
So inverted that equal to 4 binary 0 is the last of four binary numbers are set to 0.

14
00:01:10,210 --> 00:01:16,760
The inverse is setting that two ones and that works out as if in hexadecimal or 15.

15
00:01:16,750 --> 00:01:23,700
In decimal the same for decimal 1 equals this in binary.

16
00:01:23,710 --> 00:01:25,720
Equals this in hexadecimal.

17
00:01:25,740 --> 00:01:31,890
If you look at the binary and you invert the zeros to a 1 and the 1 2 0 0 you you're going to end up

18
00:01:32,040 --> 00:01:39,040
with this number and if you convert that to decimal you get to 5 4 or hexadecimal.

19
00:01:39,080 --> 00:01:47,190
If e and so forth and so one the calculator also allows you to take a sort of binary number and then

20
00:01:47,190 --> 00:01:56,280
convert it to decimal hexadecimal and the inverse values as well as taking hexadecimal values and converting

21
00:01:56,280 --> 00:01:58,980
that to decimal and binary.
