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 refers to the effect the bug has on the functionality of the application. The more the functionality is effected the higher will be the severity. For example a crash will always have the highest severity and a spelling mistake will have a low severity. Priority refers to how soon the bug should be fixed. One more point to note is that Severity is entered by the QA and the Priority to fix it is decided by the PM in consultation with the client relationship manager. By and large a high severity bug would also have high priority. BUT there are also exceptions to the rule depending on the application and release schedule. A wrong logo used on the home page of a company's web site is definitely HIGH priority whereas since its not affecting the functionality, its Severity will be LOW. Conversely a crash during a roundabout scenario which is not likely to be encountered by the client will have HIGH severity since it has a major affect on the functionality whereas the PM may set the Priority as LOW since he might have more important bugs to fix which have higher visibility to the client.

Difference is Severity defines the sevrity of bug, if any existing functionality is gone with  new feature then  that bug is given as high severity and also High Priority is given to that Bug to Fix.Severity  is the one given by Tester and Priority is given by Lead.

Severity of a bug is a technical term that denotes how serious the bug is in terms of its effect on the application being tested. Severity of a bug determines the priority of a bug.....the priority of a bug means if bugs are placed on a queue, which one should be solved first and one to be solved last based on the severity and the effect of the bug on the application.

Seviority is nothing but how much serious it is. Priority is nothing but how important it is. Suppose when a link is not working in the application. According to tester it becomes serious. Because one page is missing. When it is in the case of developer it is not that much of serious. Because it is going to developed according to customers requirement.

Severity - measures how much that issue causes deviation from the intended behaviour. you decide whether it crashes the system, missing major functionality, minor functionality, fit and finish issue and errors in messages displayed...Priority - measures the time in which the issue can be fixed (immediately it should be fixed, it should be fixed before it is sent to next level or can be postponed and can be taken up in the next release)

Severity Levels can be defined as follow:S1 - Urgent/Showstopper. Like system crash or error message forcing to close the window.Tester's ability to operate the system either totally (System Down), oralmost totally, affected. A major area of the users system is affected by the incident and it is significant to business processes.S2 - Medium/Workaround. Exist like when a problem is required in the specs but tester can go on with testing.Incident affects an area of functionality but there is a work-around which negates impact to business process.This is a problem that:a) Affects a more isolated piece of functionality.b) Occurs only at certain boundary conditions.c) Has a workaround (where "don't do that" might be an acceptable answer to the user).d) Occurs only at one or two customers. or is intermittentS3 - Low. This is for minor problems, such as failures at extreme boundary conditions that are unlikely to occur in normal use, or minor errors inlayout/formatting. Problems do not impact use of the product in any substantive way. These are incidents that are cosmetic in nature and of no or very low impact to business processes.

Both are used by the tester.
Severity and priority are set depend upon the nature of defects.

Ex:- If we are working on any project and after completion every thing was fine but there was a spelling mistake in project name. That means we have to fix that first. it means it has a high priority but low severity.

Another ex:- If one patient is suffering from high fever but while coming to hospital he got accident due to that blood is coming from his head. What would be the doctor decision. First he will do treatment of his head later on fever.
