What is inode in Linux?

Well I'm trying to grasp concept of what inode is?And after reading this article what I understand is that inode is kind of array, where as inode-number of file is the index 'i' of that array.
And as we know array have static size that's why older file system like ext3 have fixed number of inode..means you can only create limited number of files in ext3.

Can I limit the number of files to be create in Linux modern file system like ext4...?

Heres a good explanation from top to bottom: http://www.linfo.org/inode.html

TL;DR It's a unique data structure containing metadata about a file.
