File System

Ext2 was developed in 1993 & is based on concept that data is held in files that is kept in blocks
In ext2 all the data blocks are of same length which are of 1024 bytes.
If any file is of 1025 bytes then it will take two blocks of 1024 bytes
This causes average waste of half block per file
