00:00:00,360 --> 00:00:05,470

So let us learn something about access points now before we move ahead with this lecture.



2

00:00:05,790 --> 00:00:13,230

I will tell you that I'll be covering access points, epis in depth in Chapter 12 of security in networks,



3

00:00:13,560 --> 00:00:15,260

but I introduce them here.



4

00:00:15,990 --> 00:00:22,740

I understand that an access point, commonly called as an EP through its initials, is just the hub



5

00:00:23,040 --> 00:00:27,690

that accepts wireless plans via analogue wireless signals.



6

00:00:28,020 --> 00:00:31,770

And the access at layer to that is the datalink clear.



7

00:00:32,700 --> 00:00:37,730

Now, it's no secret that wireless is the key to all the networks in the world today.



8

00:00:38,100 --> 00:00:43,980

Even you are using your telephone, which is directly, wirelessly communicating to the Internet, to



9

00:00:43,980 --> 00:00:51,210

your router and a wireless network to be more even prevalent in the future than all our home appliances



10

00:00:51,210 --> 00:00:55,180

have an IP address and communicate wirelessly to function properly.



11

00:00:55,980 --> 00:01:01,740

For example, the ease of communicating on a network using an access point instead of having to use



12

00:01:01,740 --> 00:01:04,680

an Ethernet cable has changed the world forever.



13

00:01:05,040 --> 00:01:10,890

Right now, you don't even use Ethernet cables for large networks that are wireless access points or



14

00:01:10,890 --> 00:01:11,970

routers in place.



15

00:01:11,970 --> 00:01:18,480

And most probably in today's world, everything around us is directly connected through access points



16

00:01:19,140 --> 00:01:20,430

you can see on the screen.



17

00:01:20,880 --> 00:01:26,080

Access Point is allowing that PC to connect to the local area network.



18

00:01:26,340 --> 00:01:34,020

So, yeah, ensure that PC is using the Internet, that is the Internet for accessing resources on the



19

00:01:34,020 --> 00:01:34,380

Web.



20

00:01:34,650 --> 00:01:36,660

And Access Point plays an important role.



21

00:01:36,990 --> 00:01:45,480

So instead of connecting the LAN cable to the actual joining Mientkiewicz, the laptop just has to connect



22

00:01:45,480 --> 00:01:47,540

to the wireless access point and it's done.



23

00:01:47,940 --> 00:01:54,240

So, for example, if you are sitting in on the first floor and if the Access Access Point or the router



24

00:01:54,540 --> 00:02:00,780

and langauges is on the second floor, you would have to use access point in between so that you can



25

00:02:00,780 --> 00:02:05,280

directly connect to the Internet through the access point of access.



26

00:02:05,280 --> 00:02:06,420

Point was not present.



27

00:02:06,430 --> 00:02:12,330

We have to pull out the long cable and insert the main Ethernet cable to actually use the Internet.



28

00:02:12,780 --> 00:02:18,570

I hope you have a clear picture of why access points are really important and how they have changed



29

00:02:18,570 --> 00:02:24,300

the world by allowing many users trying to connect to the local network they can connect.



30

00:02:24,300 --> 00:02:32,610

Now, in one single click, the wireless client modulates a digital signal to an analog signal, which



31

00:02:32,610 --> 00:02:36,960

the access point can read and demodulator back into the digital signal.



32

00:02:37,800 --> 00:02:44,130

The access point creates one collision domain and can only run in half duplex, which is where you can



33

00:02:44,130 --> 00:02:46,730

describe access point like a hub.



34

00:02:47,580 --> 00:02:53,580

In the next lecture we will talk about wireless range extender and then in the later part of this section



35

00:02:53,580 --> 00:02:58,170

we will talk about the different convention methods commonly used in the Internet.
