1

00:00:00,256  -->  00:00:04,922
In the previous video, we already learn about
the most simple computer network,

2

00:00:05,425  -->  00:00:08,131
which is connection between two computers.

3

00:00:08,676  -->  00:00:14,757
Here is the example, we have PC 1 connected
to the PC 2 using UTP Cable.

4

00:00:15,899  -->  00:00:22,317
But if we just connecting two computer using
UTP cable like this, these two computer can’t

5

00:00:22,317  -->  00:00:23,488
communicate yet.

6

00:00:24,297  -->  00:00:30,613
If we want PC 1 and PC 2 can communicate each
others, we will need an IP Address on both

7

00:00:30,613  -->  00:00:32,680
of PC 1 and PC 2.

8

00:00:33,643  -->  00:00:35,535
So what is an IP Address?

9

00:00:36,165  -->  00:00:39,808
IP Address is the name of computer in the
computer network.

10

00:00:40,396  -->  00:00:45,962
Let’s imagine in the real world, if we want
to communicate with our friends, we will need

11

00:00:45,962  -->  00:00:48,000
to know his or her name.

12

00:00:48,456  -->  00:00:55,174
Let’s say his name is Dony, so we will call him
“hey Dony!, let’s go to eat”.

13

00:00:55,906  -->  00:01:01,862
As well as computer network, each computer
will need a name to communicate each others.

14

00:01:02,773  -->  00:01:07,225
And the name of computer in the computer network
is an IP Address.

15

00:01:07,889  -->  00:01:17,663
For example, the IP Address of PC 1 is 192.168.1.1,
if you don’t understand this numbers yet, don’t worry!

16

00:01:18,280  -->  00:01:21,548
We will learn more about IP Address in the
next video.

17

00:01:22,042  -->  00:01:26,551
For now, just understand that this is the
example of IP Address.

18

00:01:27,625  -->  00:01:33,165
And then the IP Address of PC 2 is 192.168.1.2

19

00:01:36,463  -->  00:01:42,432
Now these two computer have an IP Address,
so they can communicate each others.

20

00:01:42,987  -->  00:01:52,387
The IP Address of PC 1 is 192.168.1.1, and
the IP Address of PC 2 is 192.168.1.2.

21

00:01:52,924  -->  00:01:59,790
Let’s say PC 2 want to access data on PC 1,
so PC 2 can call the PC 1 IP Address, \which

22

00:02:00,000  -->  00:02:03,175
which is 192.168.1.1.

23

00:02:03,729  -->  00:02:06,511
This is how computer network work!

24

00:02:07,363  -->  00:02:12,932
Okay, for the summary, each computer in the
computer network will be need a name to communicate

25

00:02:12,932  -->  00:02:18,926
each others, and the name of computer in the
computer netwok is an IP Address.

26

00:02:19,897  -->  00:02:25,844
Okay I hope you understand about what is IP
Address and why we need an IP Address in the

27

00:02:25,844  -->  00:02:26,861
computer network.

28

00:02:27,449  -->  00:02:32,274
In the next video, we are going to learn how
to install Cisco Packet Tracer.

29

00:02:33,774  -->  00:02:35,388
What is Cisco Packet Tracer?

30

00:02:36,078  -->  00:02:41,305
Cisco Packet Tracer is a network simulation
tool that will help us very much to learn

31

00:02:41,305  -->  00:02:44,474
about computer network especially cisco.

32

00:02:45,573  -->  00:02:49,621
So thankyou for watching and see you on the
next video!
