TCP vs UDP: Is UDP better than TCP? - A brief comparison

TCP vs UDP- What is the better choice? Let’s Learn

Have you ever heard about TCP and UDP? If so, then it would be easy for you to evaluate the common differences between both technologies. But if you are not a tech-savvy person, then it’s important for you to read the entire article from start to end, as it would help you out in understanding everything while setting up your router, configuration of your firewall software, or searching out for some features of VPN features. But the main point is, you should first know about TCP vs UDP so you can compare the technologies and may choose the right option in the future.

To help you learn the differences, Server colocation made a brief comparison between TCP and UDP, let’s have a look and see what features they provide.


TCP vs UDP- and overview:

  • TCP: TCP mainly stands for transmission control protocol. This is basically a connection-oriented protocol which can be used by computers and system to communicate efficiently over the web. This is included in one of the most important protocols in TCP or IP networks. TCP helps users in checking errors and then guarantees complete data delivery. It also monitors that if the packets are delivered in the exact order they have been sent previously.
  • UDP: UDP mainly stands for user datagram protocol. This is basically a protocol without any connection which can simply work like TCP. However, it doesn’t feature any kind of error-checking as well as data recovery solutions. Instead, this is responsible to deliver datagrams to all the users whether they are receiving it or not.

TCP vs UDP- how does TCP differ from UDP?

TCP and UDP both have a lot of significant similarities and interesting differences that make them a hot topic of the search for many users. Both technology types are frequently used protocols that are responsible to deliver multiple packets over the web. Both of these systems operate on the transport layer of the TCP/IP protocol stack. Hence, both of them also uses the IP protocol.

Let’s understand some major differences between them.

  • Connection and connectionless:

One of the most common differences is, TCP is completely a connection-oriented protocol whereas, and UDP operates without connection and hence called a connectionless protocol. TCP tends to establish a strong connection between the receiver and the sender before the data is delivered to the recipient. However. UDP cannot establish any kind of connection before delivering data.

  • Reliability:

Is TCP better than UDP in terms of reliability? The answer is yes. TCP is a much more reliable option. Data delivered via TCP protocol would be completely guaranteed to be sent to the recipient. In case of data loss occurs in the transit, then it would efficiently recover the whole data and resend it immediately. TCP is also responsible to check thousands of packets for pitfalls, and even track the packets so that you couldn’t lose your data. As compared to that, UDP is quite an unreliable option. It doesn’t promise guaranteed delivery. Its datagram packet could even corrupt or sometimes lost in the case of transit.

  • Flow control:

If you are wondering which is better UDP or TCP, and why? Then you need to analyze the flow control mechanism of TCP. It always tends to utilize an efficient flow control system. It simply ensures that the sender is not frustrating a recipient by delivering a lot of packets simultaneously. TCP can store all the data in the send buffer solution and then get all the data back in the receive buffer solution.

So, when the application seems ready, it would immediately read all the data from its recipient buffer. And in case if that buffer is full, then the recipient won’t be able to get any more data and would start dropping it. In order to maintain this significant data delivery that could be sent to the recipient, the receiver would be responsible to tell the sender about its spare room in the receive buffer solution. So when they receive a packet every time, there would be a proper message delivered to the sender with the proper value of receivable data.

However, UDP doesn’t offer any flow control mechanism, as in this case, packets arrive continuously and even could drop as well.

  • Ordering process:

TCP always prefer systematic ordering as well as follow right sequencing details which promise that all the data packets delivered from the server would be sent to the user in the exact manner they were delivered, without any change of order. But in another case, UDP can send those packets in varied order and sequence.

  • Speed:

When it comes to speed and performance, TCP is a bit slower option than UDP. And the reason is, it has already a lot more to do than UDP. TCP is responsible to maintain a smooth connection, check all the errors, and guarantee users that all the files will be received in complete order & sequence as they were sent.

  • Use of TCP and UDP:

When we discuss usage of both technologies, we will come to know that TCP is best suitable for the applications that require some high flexibility and reliability, and where timing is not a significant concern. They easily work well with World Wide Web (www), File transfer protocol (FTP), Email (IMAP, POP, SMTP.), and others. However, UDP is best suitable for those applications that must require speed, performance, and efficiency. It works well for VPN tunneling, online gaming, and streaming heavy videos, live broadcasting, DNS, VoIP, and much more.

So if you are worried about making the right choice, it’s important to understand TCP vs UDP completely, so you can learn what’s better for your business needs.
