No, they are not the same.

Here is one link for more info, you can Google for other links with "inode" "Linux filesystem" "Unix filesystem" or similar keywords:

Here is a kernel-level description:

No. There are a lot more data blocks than inodes. A likely ratio is about 20 to 1.

You can use debugfs, ext3grep, and several other tools in tct/tsk to see a lot of the basic stats about your file system (block size, inode size, etc.)

In Linux, an "inode" is basically the representation of "a single file." The name is historical. Directories, in turn, associate names with those inodes.
