"There are two types of apartments: single-threaded apartments, and multithreaded apartments. * Single-threaded Apartments-Single-threaded apartments consist of exactly one thread, so all COM objects that live in a single-threaded apartment can receive method calls only from the one thread that belongs to that apartment. All method calls to a COM object in a single-threaded apartment are synchronized with the windows message queue for the single-threaded apartment's thread. A process with a single thread of execution is simply a special case of this model.
* Multithreaded Apartments-Multithreaded apartments consist of one or more threads, so all COM objects that live in an multithreaded apartment can receive method calls directly from any of the threads that belong to the multithreaded apartment. Threads in a multithreaded apartment use a model called free-threading. Calls to COM objects in a multithreaded apartment are synchronized by the objects themselves."

What is difference between single threaded servlet and multi threaded servlet?
The single thread model means that your servlet would not be multi-threaded. If there are two concurrent requests to your servlet then 2 instances of your servlet will be created to process these 2 requests. You can implement the single thread model by implementing the SingleThreadModel interface in your class. This is just a marker interface and does not have any methods. The multi threaded model means that your servlet would be multi-threaded and only one instance would exist. Multiple concurrent requests would be served by the same instance but in different threads. You can implement the multi threaded model by not implementing the SingleThreadModel interface in your servlet class.
Difference between single parameter sensitivity and multiple parameter sensitivity?
Difference between single parameter sensitivity and multiple parameter sensitivity is that in multiple parameter sensitivity,defined parameters cannot be measured with a high degree of accuracy in the field or in the laboratory.
Is there a difference between a bar graph and a double bar graph?
A double bar graph plots two sets of data on a single chart, whereas a bar graph plots just one.
What is the difference between bar and histogram?
Bars are for single values or classes with uniform width, and the height of each bar is the frequency. In a histogram, the classes are of different width and the heights are proportional to the frequency density. The frequency, itself, is given by the area of the "bar" above the class.
What is the difference between an outcome and an event?
An outcome is the result of a single trial. For example, if I roll a die, one outcome would be a six. An event is a collection of one or more outcomes. Using the example of rolling a die, an event might be rolling two sixes in a row. Thus this event is comprised of two outcomes - rolling and six and rolling another six.
