What is the advantage of global resource URIs (i.e. Addressing)?

Question

What is the advantage of resource references using universal URIs (like REST) ​​compared to using the proprietary id format?

For instance:

• http://host.com/student/5
• http://host.com/student?id=5

In the first approach, the entire URL is an identifier. In the second approach, only 5 is an identifier. What is the practical advantage of the first approach in the second?

Why does REST (seem) go out of its way to uphold the first approach?

- EDIT:

My question was confusing because it really asked two separate questions:

• What is the advantage of addressing?
• What is the difference between the two forms of URIs discussed above.

I answered both questions below using my own post.
