In mathematics, a tuple is a finite sequence or ordered list of numbers or, more generally, mathematical objects, which are called the elements of the tuple. An n-tuple is a tuple of n elements, where n is a non-negative integer. There is only one 0-tuple, called the empty tuple.

元組 （英語： Tuple）或译为 多元组，也称为 顺序组，泛指有限個 元素 所組成的 序列。 在數學及計算機科學分別有其特殊的意義。 数学 上， n元组 或 多元组 是对象个数 有限 的 序列。 元组由三部分组成：边界符、分隔符和元素。 通常采用的边界符是小括号“ ”，分隔符是逗号。 元组被数学家用来描述包含特定部件的 数学对象。 例如， 有向图 被定义成一个二元组（V, E），这里 V 是节点的集合， E 是 V × V 的子集，表示边。 在 類型論 中，多元組與 重類別 相關。 长度为 n …

Beyond these, the names continue as follows: a 3-tuple is a triple, a 4-tuple is a quadruple, a 5-tuple is a quintuple, a 6-tuple is a sextuple, a 7-tuple is a septuple, and so on. The general form for naming these tuples involves adding the suffix "-tuple" to the appropriate numerical prefix.

In the TCP protocol, the socket is uniquely identified by the source IP, source port, destination IP, and destination port. Why does the TCP protocol require two extra pieces of information for the receiving host to correctly demultiplex the segment and send it to the correct process?

When a 4-tuple is registered, two things happen: If the program-version-protocol 3-tuple has not yet been registered with TCP/IP for MVS, it is registered. The Portmapper assigns a port number to this combination, and that port number is the one that clients use to request the service represented by this 4-tuple. Procedure 0 for the program ...

In mathematics, a tuple is an ordered sequence of values. The values can be repeated, but their number is always finite. A tuple is often represented by a comma-delimited list whose values are enclosed in parentheses, although they're sometimes …

the UDP 4-tuple. This mechanism will allow an application to receive notifications containing throughput advice for both upstream and downstream traffic from any network elements capable of dropping or delaying packets on the path of a UDP 4-tuple. The throughput advice serves as a guideline to enhance user experience

元组（tuple）是关系数据库中的基本概念，关系是一张表，表中的每行（即数据库中的每条记录）就是一个元组，每列就是一个属性。 在二维表里，元组也称为行。

C# 4-Tuples Tuples can be very handy for developers, allowing them to return multiple values from a function, the creation of composite keys to Dictionaries and eliminates structs or classes just t...

Defining the attributes of a 4-tuple When you select option 3 or option 4 on panel DFHRP03, panel DFHRP5 is shown. If you chose option 3, some of the fields are empty, but if you chose option 4, the details of the selected 4-tuple are shown. You have to supply more information on panel DFHRP5B.
