Hello, everyone. I hope you all are fun and welcome to
the video number 1.2 in this video. We're going
to talk about communication Technologies versus communication
protocols.
Mostly people think that communication Technologies and
communication Protocols are the same thing. These are
not the same things. So let's get started the
lecture so we can differentiate between communication Technologies
and communication protocols.
So firstly we will talk about what is communication.
here
we are going to talk about our
real life communication. We have
a lot of different communication method like we speak we
can give a signal to other person to convey
our message we can talk with eyes we
can talk with our dressing. So there
are a lot of different communication Technologies if
we compare with that real life and communication Technologies.
But next we need to know what is
protocol. So for example, there are
two guys one is from Arab and one is from Japan.
both can talk
mean both can speak but one is
a Arab guy and other is a Japanese guy.
cut
so both guys can speak
with each other, but there is a barrier one
is Arab and other is a Japanese.
So how they can talk with each other. There's a
international standard language, which is English. So if
they want to communicate with each other they both
know English if they know English then they can
easily talk to each other. So this is the protocol set of rules that
how the things can communicate actually
if we move back here is the communication Technologies
which provides your
medium to send your
message from one point to another point, but
We need a communication protocol which defines
the rule how we can communicate with other.
So same like that. We
have a communication Technologies like 3G 4G
Wi-Fi, which provides us facility to
send a message from one point to
another point, but communication protocol will
Define their rules that how
we need to send the data from one point to another point
and in which format so this is
that there's the difference between communication Technologies and
communication protocols, and I hope now you guys distinguish
and understand why these
things are different from each other.
So guys see you in our next video where we're
going to talk about communication Technologies, which is
actually physical layer. So see you in the
next video. Have a good day, bye-bye.
