Pop three protocol usage.



2

00:00:07,530 --> 00:00:08,410

Hello, everyone.



3

00:00:09,120 --> 00:00:10,200

Welcome back to the course.



4

00:00:10,210 --> 00:00:15,600

Today, we're going to talk about the pop trip protocol, the pope protocol, the pope trip protocol



5

00:00:15,600 --> 00:00:21,720

actually allows the email clients to obtain email messages that are stored on a remote server.



6

00:00:21,990 --> 00:00:31,490

So the idea is that the email messages can be downloaded and read by the email holder on the local computer.



7

00:00:31,920 --> 00:00:40,260

So the pope trip protocol is basically used to download these messages from the email that is located



8

00:00:40,260 --> 00:00:43,570

on the server and store it in the local PC.



9

00:00:43,890 --> 00:00:50,330

So the whole idea behind the protocol is not to send messages, but to store them.



10

00:00:50,490 --> 00:00:57,610

And trust me, the protocol does this very fast and also it requires a very low Internet connection.



11

00:00:57,810 --> 00:01:05,220

So what we aim here is to have a tool, which is the proper protocol that can download our emails on



12

00:01:05,220 --> 00:01:12,410

a very low megabits Internet and then stored them in our computer while we're offline.



13

00:01:12,780 --> 00:01:22,530

And this protocol is basically used by the most famous graphical user interface email services, such



14

00:01:22,530 --> 00:01:25,400

as the Mail on the Apple and Outlook.



15

00:01:25,590 --> 00:01:32,670

So similarly to the previous protocol we're talking about, you can see here the diagram which shows



16

00:01:32,670 --> 00:01:37,560

how the mail server is connected to the user's computer.



17

00:01:37,980 --> 00:01:45,210

And both of the devices, the server and the computer are using the pope through protocol to communicate.



18

00:01:45,930 --> 00:01:51,750

So the client establishes a connection with the TCAP on a port.



19

00:01:51,760 --> 00:01:56,490

One hundred and ten, we're checking the user name and password here.



20

00:01:56,710 --> 00:02:03,690

And then the list of emails, the number of emails and their sizes is provided and then each of the



21

00:02:03,690 --> 00:02:09,120

emails is retrieved and sent it from the server to the user computer.



22

00:02:09,930 --> 00:02:15,990

And once the last message has been sent, then the operation is completed and we receive all of the



23

00:02:15,990 --> 00:02:17,760

emails from the external server.



24

00:02:17,880 --> 00:02:21,640

So this is the brief introduction to the PopChips Protocol.



25

00:02:22,200 --> 00:02:23,670

I hope this was useful.



26

00:02:23,670 --> 00:02:29,560

And if you didn't understand it quite well, you can actually repeat that video because the information



27

00:02:29,560 --> 00:02:34,800

they give you is quite important to understand the basics, because in the next lecture, we're going



28

00:02:34,800 --> 00:02:42,070

to use the Pope Library in Python in order to generate and record emails with the pope through protocol.



29

00:02:42,420 --> 00:02:43,030

That's it.



30

00:02:43,050 --> 00:02:44,370

Thank you very much for watching.



31

00:02:44,370 --> 00:02:46,190

And I will see you in the next video.
