To test the maximum load a system can resist.
It is a part of performance testing. To test whether the 
system can sustain a the specified load. Virtual users are 
created using automated tools or manually and they are set 
to test to interact with the application simultaneously.

virtual usres are created to to apply rated loads on  the 
server to estimate it's perfromance at different load 
conditions.
Normally in LoadRunner 'VUGen' function will generate 
multiple virtual users and applies the multiple virtual 
users simulteneously on the server.
this replicates the natural load conditions.

HI

virtual Users are created to Check the performance of the 
application either in client/Server application or in web 
application .
To test the system 
1.How it withstand different loads with different virtual 
users.
e. To check the response-time decreases with max No of 
virtual users.

Virtual Users are created to check the performance of the 
application either in client/Server application, database 
or in web application.

Load Runner Virtual User generator is used to generate the 
multiple virtual users. Since it difficult to set 
environment to check the performance testing of such 
application in real scenario we create virtual user.

Suppose we have to check the application for 100 users and 
every 100 user has to access the application at the same 
point of time. Firstly it is very difficult to set 100 
terminal and secondly very difficult to hit the system at 
the same point of time So virtual user are generated for 
that.
