I've never heard of a "defined" subset. If you have a set of numbers (they could be integers, or real, or complex, but we'll stick with integers just to make it obvious), than a "defined" subset just means that you know (can "define") a selection from that set. For example, given a set...
{6, 27, 3, 6, 11, 32}
... a defined subset can be simply {27, 11}.
There's no magic here and it's not a special term (in fact, everyone just calls that a subset I'm pretty sure you're just a tad confused because your professor/author of your textbook is using this term for no apparent reason). This question is in geometry however, so I'll take it a bit further (using simple geometry).
If you know a set is a region within the square of width times height, you can say that a defined sub-set of the are of the square is the lower-right triangle portion, which would be width times height divided by two (again, super simple example of a potentially area subset... not trying to offend).
If, however, you're talking about a "proper subset", that's something different entirely and I would erase this answer in an instant to explain.
Basically, your question is unclear.

What is a subset of records?
a subset is a group that is contained within the other group. So the set of letters {a, b} is a subset of {a, b, c} It is also worth noting that {a, b} is also a subset of itself {a, b}. In set arithmatic a subset I believe is defined like this: set1 is a subset of set2 if set1 + set2 = set2. {a, b} + {a, b, c} = {a, b, c}
How is a relation between two sets defined?
A relation between two sets is defined to be any subset of the two set's Cartesian product. See related links for more information and an example.
What is the meaning of domain?
Domain can be defined as an area that is controlled by a ruler. In the internet a domain is a subset in which web addresses share a common suffix.
What is the difference between a subset and a proper subset?

What are the ASCII codes for subset and proper subset?
Since ASCII ⊊ unicode, I don't know if there are ASCII codes for subset and proper subset. There are Unicode characters for subset and proper subset though: Subset: ⊂, ⊂, ⊂ Subset (or equal): ⊆, ⊆, ⊆ Proper subset: ⊊, ⊊,
How do you refine a subset?
If a subset is defined by enumeration, you could remove "duplicate" entries. If defined by some generating function you might be able to simplify the function.
Why is every set a subset of itself?
That is how "subsets" are defined.

What are the substance of a line and defined each subset?
A line is an abstract geometric concept and there are no substances in a line.

What is an interval in math term?
An interval is a subset of an order-numbered set; the interval includes a highest- numbered member of the subset and a lowest-numbered member of the subset and all members of the set with order numbers with values between that of the highest- and lowest-numbered members. This is more exactly called a "closed interval". An "open interval" is defined in the same way, except that the lowest-numbered and highest-numbered limits are not part of the subset.
Why can a proper subset be a subset of itself?
Because every set is a subset of itself. A proper subset cannot, however, be a proper subset of itself.
What is a subsets?
A is a subset of a set B if every element of A is also an element of B.
What Set of counting number greater than 4?
It is a subset of the set of integers and may be defined as:{x : x belongs to N, x > 4}
