So let us learn something about access points now before we move ahead with this lecture.
I will tell you that I'll be covering access points, epis in depth in Chapter 12 of security in networks,
but I introduce them here.
I understand that an access point, commonly called as an EP through its initials, is just the hub
that accepts wireless plans via analogue wireless signals.
And the access at layer to that is the datalink clear.
Now, it's no secret that wireless is the key to all the networks in the world today.
Even you are using your telephone, which is directly, wirelessly communicating to the Internet, to
your router and a wireless network to be more even prevalent in the future than all our home appliances
have an IP address and communicate wirelessly to function properly.
For example, the ease of communicating on a network using an access point instead of having to use
an Ethernet cable has changed the world forever.
Right now, you don't even use Ethernet cables for large networks that are wireless access points or
routers in place.
And most probably in today's world, everything around us is directly connected through access points
you can see on the screen.
Access Point is allowing that PC to connect to the local area network.
So, yeah, ensure that PC is using the Internet, that is the Internet for accessing resources on the
Web.
And Access Point plays an important role.
So instead of connecting the LAN cable to the actual joining Mientkiewicz, the laptop just has to connect
to the wireless access point and it's done.
So, for example, if you are sitting in on the first floor and if the Access Access Point or the router
and langauges is on the second floor, you would have to use access point in between so that you can
directly connect to the Internet through the access point of access.
Point was not present.
We have to pull out the long cable and insert the main Ethernet cable to actually use the Internet.
I hope you have a clear picture of why access points are really important and how they have changed
the world by allowing many users trying to connect to the local network they can connect.
Now, in one single click, the wireless client modulates a digital signal to an analog signal, which
the access point can read and demodulator back into the digital signal.
The access point creates one collision domain and can only run in half duplex, which is where you can
describe access point like a hub.
In the next lecture we will talk about wireless range extender and then in the later part of this section
we will talk about the different convention methods commonly used in the Internet.
