There's many IP protocols, including TCP and UDP among others.
See this list for reference: <a href="https://en.wikipedia.org/wiki/List_of_IP_protocol_numbers" rel="nofollow noreferrer">List of IP protocol numbers</a>

Some are rarely (or never) used, why others are widely used.

Their usage depend on their usefulness.

UDP provide a fast, but unreliable, mean to transfer data. A typical use is for audio and video streaming, where re-sending a missed packet is not useful, since, if you missed an image in a movie there's no point to displaying it anymore

TCP provide a reliable connection, and handle error and retransmission of lost packet. This is vital to exchange of data the must reach the destination intact.

So there's more use case of TCP than UDP, but the latter is still widely used.

blocks|key|4558924|text|历史原因:+TCP/IP是Internet协议的最初组合。我们谈论的是1974-75年左右。UDP是在1980年诞生的。那时，人们已经开始谈论TCP/IP，也就是使用TCP的Internet协议。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|entityMap^0^^$0|@$1|2|3|4|5|6|7|C|8|@]|9|@]|A|$]]]|B|$]]

Historical reasons: TCP/IP was the initial combination for the Internet Protocol. We are talking about around 1974-75. UDP came to life in 1980. By that time, people already talked about TCP/IP and meant the Internet Protocol using TCP.

blocks|key|3415804|text|TCP和IP过去和现在仍然被认为是IP套件的核心协议，TCP也在UDP之前。该套件的起源是在面向数据包的网络上使用串行行重新创建以前的环境，而TCP套接字非常类似于此。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|entityMap^0^^$0|@$1|2|3|4|5|6|7|C|8|@]|9|@]|A|$]]]|B|$]]

TCP and IP were and still are considered the core protocols of the IP suite, with TCP also preceding UDP by far. The suite's origins were about recreating the former environment with serial lines over a packet oriented network and a TCP socket pretty closely resembles that.

blocks|key|3415889|text|实际上，这取决于你在互联网上的需求。如果您总是使用需要可靠和面向连接的服务的Internet应用程序，如Web、文件传输、电子邮件、远程终端访问等，则TCP协议是您需要的最佳协议。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3415890|因为，TCP协议为使用它的应用程序提供面向连接的可靠连接.这意味着您的数据将始终到达目的地(在IP报头中定义)而不会丢失。这些任务通过TCP报头中的序列号字段、确认号字段和标志位来完成。|3415891|因此，如果您使用需要TCP协议的应用程序进行传输，那么从您的角度来看，TCP/IP比UDP/IP更受欢迎。如果有人使用不需要可实现或面向连接的服务的应用程序，他认为UDP/IP比TCP/IP更受欢迎。|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|G|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|H|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|I|8|@]|9|@]|A|$]]]|F|$]]

Actually it depends on your need in the Internet. If you always use Internet applications which need reliable and connection-oriented service such as Web, File transfer, E-Mail, Remote Terminal access and so on, TCP protocol is the best protocol in your needs. 

Because, TCP protocol serves connection-oriented and reliable connection for applications who use it. That means your data will always reach the destination(defined in IP header) with no loss. These task are accomplished by Sequence number field, Acknowledgment number field and Flag bits inside the TCP header.

As a result, if you use applications which need TCP protocol for transporting, TCP/IP is more popular than UDP/IP from your perspective. If someone uses applications which don't need realiable or connection-oriented service, from his perspective UDP/IP is more popular than TCP/IP.

According to 7 Layers of the OSI Model, IP is located at layer 3 (Network), while TCP and UDP are located on layer 4 (Transport).

Just for the sake of curiosity, why the combination of "TCP/IP" term is more popular than "UDP/IP"?

I've been searching on internet about this, however the only site that uses UDP/IP term is <a href="http://searchmicroservices.techtarget.com/definition/UDP-User-Datagram-Protocol" rel="nofollow noreferrer">http://searchmicroservices.techtarget.com/definition/UDP-User-Datagram-Protocol</a>

<blockquote>
 Both UDP and TCP run on top of the Internet Protocol (IP) and are
 sometimes referred to as UDP/IP or TCP/IP.
</blockquote>

Btw, I'm not talking about the difference between TCP vs UDP and why TCP is more popular instead of UDP. 

I'm just curious why the combination of "TCP/IP" term is more popular than "UDP/IP"?

It's common to hear about "TCP/IP" term but not "UDP/IP" term right? Any idea why?
