We often use the word set in our day to day life. For example, we usually have dinner sets in our homes and as the name suggests, a dinner set is a collection of cups, plates, dishes, saucers etc., used for serving food and dinning. So, as with a dinner set, a set is a collection of objects of same kind. And this set can be of two types in our practical lives.

For instance, if I asked you to create a collection of all the songs recorded by Lady Gaga, you can easily do that with the help of some research and the internet. But, instead of a collection of all songs, I asked you to create a collection of top five songs recorded by Lady Gaga. Now, collection of all songs and collection of top five songs they both are collections, they both are sets but there’s a big difference between both.
A collection of all songs will always be the same, whether you will create that collection or I will create that collection, that collection will always have same songs. Yeah, the order in which we collect these songs can be different but the overall collection will always be the same…..
