Uh huh[ Music] we tee Hello everyone, this is me. I’m against today’s opposition to Korea’s products and technological sciences, so I prepared this video because some people seem to have a hard time with it. I sounded the excuse in the video earlier, but let’s take a clay time today with the president of the corporation and learn more about refund Korea. Then let’s meet with the president of the corporation. I made a questionnaire today for things I was personally curious about. I came back know after consideration of I can send and receive bellows. I can make and receive orders with that KakaoTalk messenger, but if I use the sip ip protocol, I can receive calls and return them to other people, and at the same time, I can receive various applications. It is a protocol that acquired In short, etiquette can be defined as a predict. Socially, in movies, etiquette is applicable in numerous means. First, I will tell you what it means to be used in computer 0. So now, coding t coding in English is If you utters it in Korean, how to encrypt and decrypt the password So compiling the password 1 encryption will be coding.Decrypting the password will be coding like that. For sample, in the case of the old days, if you send the message 1004, the recipient thinks it’s an angel. One of them is the sip ip protocol. Oh, the next question is pbx. When I hear the word pbx, I can’t figure out what it is, but I’ll explain what it is. But if you speak Korean, you will become a telephone switchboard. So in the old days, you manually lost the phone line and connected it. Now, in the Internet age, application is the equipment that educates the phone. So, it is integrated into ip- pbx and now analog. If we use a signal together, we call it pab x. It’s easy to do internet telephony. You can do it like this. Well, so that three people can communicate with each other like this, we started pbx. You can displace multiple designs at the same time with this pbx. It’s this pbx that represents that capacity. Ummm, pd x is a very important bullet. Why is that right? It’s very important, but if we roughly use the phone, we don’t see it.You won’t see it, so people don’t see it very well. That’s right, the cell phone that Jenna abused is also calling a friend. Then the pope will likewise go through the country. Oh, so the next question you just said is voip. Please give me a little admiration. Why did you try that phone with boo 10 ping er kakaotalk? 4 Find it and you will become a vip. In English, it is called Voice of Internet Protocol. So, the swallow ip protocol now exists in vip. So, there is a technical difference between the method through KakaoTalk and the method to connect to the Internet through a regular phone. So, in 9 times about that, our material uses the sip ip protocol. Go KakaoTalk is a big category, and you can think of it as working the tcp ip protocol. Then, when you give digital data, you clarified coding and b coding earlier. Can you tell if the difference is 60 acquired? 4 How can I tell you about the coding? I’m going to tell you that the distant intend is this dictionary tree and deciphering is the decryption, but it would be easier to express it like this. I use various contracted registers, and the recipient needs the software to unpack the squeezed file to use it. Now, when you download it and cast it to see your feet or play it, you need a separate player, so that player will decode it[ Music] It sounds like a difficult word, but using a lot of arch is the most common thing in our life. In the case of d3 folders, the process of converting music into mp3 files with 1 banana will be coding, and the process of playing the mp3 file will be decoding. But it’s difficult to talk to parties because they only use English because most of the technology was developed abroad first, so the period itself is the same as we call it a computer thing. Since it was developed in a foreign country, what are the other advantages of altering from the existing analog method to the digital method here? It will be analog. The speaker’s eternal life is played through a vacuum tube, and in order for us to listen to it on our cellphones, we have to convert the analog racket root to an mp3 file and play it on our cellphone. But what are the advantages of a digital camera? I want to change the ringtone of the music I have on my phone. Then, like in the old days, I have to release the music from the lp account each time I upload the phone. In a nutshell, you can say that the source is exclusive. And the digital generator can be used in front of the dragon for various purposes. You can download it and use it as background music on your telephone, or you can use it as an alarm ringtone in the morning, and now the TV is on. It can be a test when you see it, and now you can use the analog music as the ringing sound of digital machines, and now you can change the mp3 file, so the answer is as follows. and emotional I think it’s certain differences. Then the question is a little connection. So the word I came up with is me, but I remember the word bit p. 4 feet Please briefly illustrate what is necessary. Although it is something that needs to be studied, p2p is now divided into two abbreviations. One is a peer peer, the other is a pulse, but it is used as a fixing. To set it simply, one-to-one communication is called p2p. It’s a little unfamiliar, one-to-one call calls would be comfortable, but be happy. I’ve seen a lot of material in English, so I’m interpret again and now it’s good to use the name one-on-one, but we too habitually merely to prevent p2p mistranslation, uh So, what can I do with my friends one-on-one messenger like this , can you see it as p2p? That’s right. For illustration, let’s make it alone 4 Speaking of which, several people communicate with one another Let’s talk. This is gonna be my multi-connection. It will be a single tie when, for illustration, a multi-party call, and hey, it will be a multi-colored poem that can be communicated to parties at the same time.[ music ].
