In the mesh topology, each computer is connected to the other with a separate physical link in a network. It is most reliable topology as the network does not get down in case one of the nodes is failed.

It is similar to MacOS X architecture

It acts as an intermediary between the iPhone and iPod hardware an the appearing applications on the screen

The user created applications never interact directly with the appropriate drivers, which protects the user applications from changes to the hardware. 

You can format the BO Reports by using various features available. You can turn the table reports into a 2-Dimensional or 3-Dimensional charts. You can apply an Alert to show some data in a different format , based on some business rule. You can also create some prompts, which will asks user to give some input values before seeing the reports, this way they will see only filtered data.

An user account is not a physical structure in Database but it is having important relationship to the objects in the database and will be having certain privileges. 95. When will the data in the snapshot log be used? - We must be able to create a after row trigger on table (i.e., it should be not be already available) After giving table privileges. We cannot specify snapshot log name because oracle uses the name of the master table in the name of the database objects that support its snapshot log. The master table name should be less than or equal to 23 characters. (The table name created will be MLOGS_tablename, and trigger name will be TLOGS name).

Variables declared within a method are local variables. Variables declared within the class are member variables.  Variables declared within the class with static modifier are class variables 

There are two modes of operations that are necessary to run depending on the value returned by the startcommand(). The modes are as follows:
-  START_STICKY: this mode is used for the services that are explicitly started and stopped according to the need and the requirement of the user.
- START_NOT_STICKY or START_REDELIEVER_INTENT: this service mode is used for services that are running only when the processing command sent to them. That means these run on the basis of the command that is passed to them by giving the instruction of execution.
- Clients uses the Context.bindService() that is used to get the persistent connection for a service. To create a service that is not already running the command onCreate is used.

For launching an application, we will need to create an intent that explicitly defines the activity that we wish to start. For example:

Code

        Intent intent = new Intent(this, MyTestActivity.class);

        startActivity(intent);

An abstract class is defined with the keyword abstract Eg:
public abstract class MyClass { }
