This means that:
Bug affacting the application functionality sevierly but 
the it has less priority to fix it.

For eg read the following bug description:

Session is not expiring after clicking on logout button in 
any screen.

if we click on logout button it is navigating to login 
page,but if we click on browser back button again it is 
navigating to previously viewed page and not allowing to do 
any operations.

High severity means, becuase of that defect user is unable 
to do any operation.

Low priority, this scenario occurs rarely or among 50000 
users only one user tries that situation 

Let me explain you clearly

The system is hanging/crashing if user is trying to access 
a help page, but that help page will be opened by users 
rarely.

Severity describes the seriousness of the bug. 

Due to a bug a total module may not be accessed.For example 

bug1: if "Application"button  is clicked then it should 
open the application form page. If the button click does 
not work then it can be described as severity is "high". 

bug2: If the click of "Application" button opens the 
application page but the details needs to be displayed in 
the current page are not displayed then it can be described 
as severity is "medium".

bug3: If the caption of the "Application" button is 
misspelled as "Aplication" then it can be described as 
severity is "low"

Priority describes what is the bug which needs to be fixed 
at the earliest. This is normally decided by the PM. 

For example in the above case if the "application module" 
need not be submitted immediately then bug1 and bug3 may be 
given "high" priority where as bug2 may be given 
priority "low"

In the above case if the "application module" has to be 
given immediately then all the three bugs bug1,bug2,bug3 
are given "high" priority.

Severity
How bad the bug is and how it impact on our Application.
Priority 
what is the bug and when We have to fix it.

I would like to give one Example

an application which generates some banking related reports 
weekly, monthly, quarterly & yearly by doing some 
calculations. If there is a fault while calculating yearly 
report. This is a high severity fault but low priority 
because this fault can be fixed in the next release as a 
change request.

if am wrong then please send me mail

Seveierity means: how the bug affect the functionality of 
the application.
priority means how urgently the bug need to fix it

Example if 2 user login the same application 1 user can 
able to access the application but the 2nd person can't 
able to access the application

In a module of say two interfaces,the link between them is 
broken or it is not functioning
