Answer / rajhshekhar aletty
using hard link, we can't create links for directories. the
link can be created within the same File System, the link
can't span into an other File System.
using soft (symbol) link, we can create links for
directories moreover that link can span into an other File
System.

Answer / linuxdemon
soft link is like shortcut.so if you delete the softlink
file, the original file wont get deleted.
Hard link is like real copy of the file.so if you delete the
hardlink file, the original file will be deleted.
ln filename hardlinkfilename
ln -s filename softlinkfilename

Soft Link: When we create a soft link, the link is created and stored in same address where the file is stored. The disadvantage of this type of link is if we delete the file the link becomes broken link and our data is lost.
Ex: ln -s data.text slink.text
If we delete data.text, slink.text link becomes broken link and our data lost.
Hard Link: When we create a hard link, the link is created and
stored in different address. But if we delete the file , the file is deleted and the link remain active so we won't loss the data.
Ex: ln data.text hlink.text
If we delete the file data.text, our data would be accessible through the hlink.text.

Soft Link:
1. It can be created across file system
2. Different inode number than original file.
3. On deleting original file soft link cannot be accessed.
4. Can be created on a file or directory.
5. Source file need not exist for soft link creation.
6. Need extra memory to store data of original file.
7. Access to the file is slower due to overhead to access
file.
Hard Link:
1. Only within file system.
2. Same inode number as original file.
3. It can still be accessed.
4. Only on files.
5. Source file should exist.
6. Not required.
7. Faster than soft link.
