Our today's topic is networking networking devices, a network consist of two or more computers that
are linked in order to share resources and to exchange funds the networking devices.
Our first one is Lenn.
That is a local area, network secondees, modem or Wi-Fi router, today's switch or server.
And the last is Bluetooth.
But in this session, I'm going to teach you about Wi-Fi.
Routers of Wi-Fi, rather, is a device that performs the function of a router and also includes the
function of a wireless access point.
It is used to provide access to the Internet or a private computer network.
And these are mainly of three types.
First one is via, the second is wireless and third one is hybrid.
Now let's see the difference between wired and wireless router from installation point of view of wired
connection is rather simple to set up.
All you need is a connecting cable from your computer to your outer and wireless network.
Take a bit more work to setup and you will need to place the router in a location where your computer
will receive a clear signal.
And from a security point of view, wireless network do pose some security risk because they are usually
being broadcast in public places.
Wireless signal encryption offers some protection, but wireless is still not secure as Ethernet and
other wire connections.
Here are some tips to secure your Wi-Fi after your first step is to change the society so that it is
difficult for attackers to guess about manufacturer to name and model number of rather used.
Our second tip is activate encryption, use the latest encryption that is Wi-Fi protected access to.
Our next step is activist, one for both private and public networks, then turn off guest networks.
Our next step is turn off Wi-Fi protected setup, then disable the ECB and use a static IP range instead.
Our next step is done on Mac address filtering and our last step is change the default password and
use a strong password instead.
Strong password means a combination of small and capital letters, along with numbers and special characters,
as you can see in this example.
OK, now let's talk a bit about IP addresses.
So what is IP address?
IP address is a unique identity of a computer system in a network.
There are two types of IP addresses or we can see it.
There are two versions of IP addresses, IP words, and for an IP, more than six IP, more than four
is a 32 bit network address and IP more than six is a 128 bit address.
And there are two types of IP addresses.
First, one is public and second is private.
Public IP address is the one which is provided by your Internet service provider to your modem and private
IP address is the one which is provided by your modem to the PC.
OK, let's not deep dive in IP addresses.
So that's it for this doctorial.
