##### General Explaination and use-case
+

There are two types of system links in linux:
+
1. Hard Links: Its is like having an alias name to an existing file. It links _(better term: syncs)_ two or more file names with the same [inode](https://en.wikipedia.org/wiki/Inode). ***You can only create hardlinks for files & folders on the same filesystem or partition***. One file can have multiple hardlinks.

2. Soft Links: A soft link can be related to a shortcut in windows, it allows a file to be accessed from one directory to other without having to keep 2 copies of it. Soft Links can be created across different filesystems and partitions.
