    Do you use VPN in Taiwan?
    TCP and UPD protocols in VPN
    Information security has become important in the 21st century. Privacy, availability, and integrity are the factors that determine whether your information is secure or not. Everyone knows how to get privacy and accessibility. But here’s how not to violate the integrity of information, when it is constantly transmitted over the network. To understand how to cope with this task, we should plunge into network protocols, namely TCP and UPD. They are necessary so that information can move from one node to another.

    So, next we will look at the differences between these protocols, what they are, as well as when and in what situation it is better to use each of them.

    UPD Protocol
    A special feature of the UPD Protocol is that it does not require a receiver connection to transmit information. You send information to him without consent. In addition, it is not a fact that this recipient exists. In addition, when sending data, the UPD Protocol does not promise ordering of information. Rather, on the contrary, it will be scattered. This is because the UPD Protocol is aimed at the transfer rate. It is useful in situations where it is important for the sender to send information quickly and there is no time to interact with it in any way. But at the same time, there is a possibility that the information will not reach the recipient at all. It also happens that the data that comes from the sender begins to be duplicated. If you objectively evaluate this Protocol, it is not reliable when transmitting information from one node to another.

    In addition, when you have passed the information to the recipient, it is difficult for him to understand whether all the data came, since the UPD Protocol does not make it clear. It doesn’t highlight errors and things like that.

    TCP
    The TCP Protocol is more reliable than the UPD Protocol. In order to start sending data, it needs the consent and connection of both nodes. This increases the reliability of the transmitted information.

    The transmission of information over the TCP Protocol begins with the establishment of a connection with the recipient. He must let us know that he is ready to receive information. Only then does the data transfer begin. With the TCP Protocol, you can be sure that the recipient is real and ready to receive information from you. This increases the reliability of the transmitted data. After the process is completed, the sender must inform that no more information will be received. The recipient must reply that he understood this and received all the data.

    Information is transmitted in packets. Each packet is numbered and transmitted in connection with its sequence number. In addition, after sending several packets, the TCP Protocol will ask the recipient to confirm that they were received. If there is no response, the transfer operation is repeated. And this happens several times. If all attempts fail, the TCP Protocol breaks the connection. However, if the network between the nodes is weak, the requests for receiving will occur more often. This is the peculiarity of the TCP connection. It is ready to work with any networks, without paying attention to their reliability.

    Most often, TCP protocols are used in two cases. The first – at authorization. The second is when encrypted information is transmitted and it is necessary to make sure that the information has reached the recipient.

    Differences between UPD and TCP protocols.
    So, let’s analyze the differences between these protocols.

    1. The TCP Protocol establishes a connection with the receiver, which the UPD Protocol does not.
    2. The TCP Protocol is reliable because it requests information about the receipt. If it is not present, repeated attempts are made to transmit the data. The UPD Protocol is unreliable because it is not known whether the information will reach the recipient.
    3. The TCP Protocol transmits data in the correct order, which the UPD Protocol does not.
    As you can understand, the TCP Protocol has a much greater reliability of information transmission in comparison with the UPD Protocol. But this does not mean that it should be discounted. It has a high transfer rate, which is very useful in network games or for watching streaming video files.

    It is difficult to underestimate what a VPN connection channel means on a computer or phone, but some risks remain. This technology is reliable and safe, but services that provide services can be unreliable – both collect statistics and store logs (history); It’s very difficult to configure and control.

    In addition, one VPN service is different for another. Free ones, for example, often support servers by selling your personal data to advertisers who show you ads based on this data. And this is considered the norm, for free after all. Yes, minus one plus (sounds nice), there is no protection from snooping, but bypassing locks is still present.

    Virtual Private Network is, in fact, a transit point for traffic. Simple and sophisticated, “a weapon from more civilized times,” the VPN takes your request to itself and redirects it to where it is needed. So, the traffic is already coming not from you, but from the VPN, the server of which can be located even in Antarctica, even in Atlantis, even on the Moon.

    If you like to visit a cafe and sit there on the Internet via Wi-Fi or often travel and connect to open Wi-Fi points-no brazen hacker sitting at the next table will intercept the data of your plastic card with a CVV code or steal the password from the payment system along with your money. And it doesn’t matter whether you work from a laptop or a mobile device – without a VPN, they are equally unprotected.
    You value anonymity and you don’t like the fact that any system administrator of the provider has access to the sites you visited or from which EPS you Deposit/withdraw large amounts. The provider will no longer know which sites you visit, and the sites will no longer know who visited them.
    At work, you like to sit in YouTube/Vkontakte/messengers, but do not want your boss or system administrator to get wind of it. I know that you are a successful investor and have not been going to work for a long time, just in case 🙂
    I recommend you 翻牆TOPVPN
    Want to see the Internet as it should be-visit sites without restrictions of the service, which simply blocks sites in batches. At the time of writing, more than 2 million sites were blocked (statistics are kept here). It is also not uncommon for a specific page or section to be blocked, and the provider blocks the entire site without understanding it.
    Does your favorite service restrict access from your country or grant privileges / bonuses/discounts to specific countries? With VPN, become a resident of any country and get all the benefits of the services.

    Sometimes I use vpn, but I’m using it from the computer in the Google Chrome browser, I only use it, but I don’t have it on the phone. I usually go to sites that are closed in my country from a computer, I just change the country to manual and that’s all. This is very convenient and helps to hide my ip address. Although it can be seen by the government or individual hackers, it doesn’t bother me much. I don’t do anything criminal.
