Hello everyone. Welcome to another video from
section 2 and map Essentials. In
this video. We're going to have an introduction to
TCP and UDP.
Transfer protocol or TCP is a connection-oriented protocol,
which means once a conditioned stimulus is going to
set up a connection and start transferring the data.
And UDP or user datagram protocol is
simpler and connectionless, which
means start sending and doesn't curve to rival, not
make sure to make it simple for you.
Let's go a little deeper about it to make sure you design everything TCP
is a connection-oriented. Protocols.
I mentioned, whereas UDP is a connectionless protocol, but
the key difference between these two between TCP and UDP is
a speed.
So this is a little bit slower than you review, but
overall Europe is much faster and simpler.
But a new table faculties TCP provide
an Orient ordered deliver of data
from user to server. Whereas UDP
is not dedicate to end-to-end communication and
action. I'm going to pay attention to this fact in the next slide
and talking about the security of each Portugal.
Let's talk about the connection. Status of each Port.
O'Call TCP requires an established connection
to transmit the data connection. Should be closed. Once
transmission is complete, but in UDP connectionless protocol
with no requirement, for opening also
TCP can guarantee delivery of the data
to the decision router, but you cannot guarantee
delivery of data to the destination. In
other hand TCP have error checking and acknowledgement of
a narrator, but you do PB.
Basic error checking. Let's talk
about level security as we talking about a security and discard
my point of view. As I mentioned last slide. This
is more secure than you to print out the first
points because of the following reasons.
As I mentioned last, I TCP make sure
I guarantee that data is going to transfer between two
points and also have error checking.
But this is considering a more secure than European animals.
Initial sequence numbers to start off the transmission.
So we can Define the TCP is more secure than
UDP, but Europe is much faster than
TCP. It's up to you. When
do you want to use, UDP or TCP
in your connection? When we try to analyze
the packets anticipate Hyuna p analyzing
the package. That's use TCP protocol is much harder
than UDP. This have a summary.
Person talking about UDP and TCP, and creepy from
them. And Next Step was some example from TCP
and UDP.
And also talking about which one is more
secure than the other in
the next video and I'll talk about MATC pants
in a scan. I'm going to show you how to do
that in a real word. Good luck.
