A Name-Value Pair is common method of organizing information in a computer.
Typically, it is used in Internet Protocols, Cookies, Query Strings, and in many Programming Languages.
The Name portion of a Name-Value Pair is what is being described. It can also be described as label.
The Value is the actual description.
In short, the Name gives the value its meaning.
An example will best explain Name-Value Pairs. In this case, the following describes a product using Name-Value Pairs:
Title: Hungry Dog Chow Price: $5.99 Product Code: HDC-4453 Quantity In Stock: 23 Product URL: http://www.hungrydogchow.com/product.asp?id=451232
Now, the Names above are: Title, Price, Product Code, Quantity In Stock, Description, and Product URL.
Each of these has a value, making a pair: Hungry Dog Chow, $5.99, HDC-4453, etc.
Obviously, with the Name of Price, you know that $5.99 is how much Hungry Dog Chow costs.
The flexibility of Name-Value Pairs are the core of why they are useful when communicating on the internet.
