These objects provide two levels of scope:

Application State

Data stored in the application object can be shared by all the sessions of the application.

Application object stores data in the key value pair.

The standard query operators implement the IEnumerable<T> or the IQueryable<T> interface in C# and the IEnumerable(Of T) or the IQueryable(Of T) interface in Visual Basic.

Marshalling is the process of gathering data from one or more applications or non-contiguous sources in computer storage, putting the data pieces into a message buffer, and organizing or converting the data into a format that is prescribed for a particular receiver or programming interface.  

RIP is a is an interior gateway protocol that was often used in interior networks and in some degree in internet networks. It helps the router adapt to the modifications that are made in a network regarding connections. Now it become less used since more efficient protocols were implemented like OSPF or IS-IS. It is limited to a lower number of routers, a maximum of fifteen router.

Retain -Specifies that retain should be invoked on the object upon assignment. takes ownership of an object

Assign - Specifies that the setter uses simple assignment. Uses on attribute of scalar type like float,int.

In WF 4.0, the following two types of workflows are used:

 
     Flowchart workflows - Helps you to create workflows using the common flowchart elements. In WF, the Flowchart activity is generally used to implement a non-sequential workflow, and occasionally it implements sequential workflows in case the FlowDecision nodes are not used. The Flowchart activity contains a collection of flow nodes, which inherit from the FlowNode class. The following types of nodes or elements can be a part of a flowchart:
                 => FlowStep - Executes activities of a flowchart in a sequence.
                 => FlowDecision - Shows the execution on the basis of a Boolean condition.   It is similar to the If construct.
                 => FlowSwitch - Shows the execution on the basis of an exclusive switch. It is similar to the Switch construct.


      Procedural workflows - Helps you to create workflows using basic and sequential execution standards. In WF, procedural workflows use flow control constructs, such as While, Switch, ForEach, and If, to execute activities. These flow control constructs are similar to those found in procedural languages. Procedural workflows can also contain other flow control activities, such as Flowchart and Sequence.

A protected method may only be accessed by classes or interfaces of the same package or by subclasses of the class in which it is declared.
