What are different switching methods used by a switch to send data?

  
Switch adopts two methods foe sending data,

Cut Through Switching:-
In this method of switching data frames are send to the destination computer without error and integrity checking.

Store and Forward Switching:-
In this method the switch sends the data frames after receiving all the frames well as after error and integrity checking. (More...)

(2)detaching
(3)Attaching databases
(4)Replication
(5) DTS
(6)BCP
(7)logshipping

Real software is developing a speech-based user interface for blind people. However, speech based interface are difficult to design and time given by the client is short. To develop a functional interface without any errors, the company wants to first evaluate the prototype. They used the storyboard technique to demonstrate the functionality of the application. However, this technique was unable to demonstrate the interactive feature of the application. Analyze and provide solution for the above scenario?

  
1, The design team of Real software should have used the Sketching technique because storyboard technique would only provide the flow and features of the interface.

2, The design team of Real software should have used the Horizontal Prototyping because storyboard technique would only provide the flow of the interface.

3, The design team of Real software should have used the Wizard of Oz technique because storyboard technique would only provide the flow and features of the interface

4, The design team of Real software should have used the Vertical Prototyping because storyboard technique would only provide the flow of the interface.

You are designing a single person shooter game application. The player can choose between multiple guns.
1) Pistol with 5 bullets
2) Shotgun with 100 bullets
3) Grenade Launcher with 20 grenades

Each gun will have different sound effects and graphics.

Pressing Ctrl+Space should rotate between guns.
Which design pattern should you employ for this?

  
Use Strategy Pattern.

Explanation: Each gun having different performance and graphics.
So this can be accomodated in the algorithm.

Strategy pattern is best suited for shifting the guns/algorithms

There will be a IGun interface implemented by 3 classes
Pistol : IGun
Shotgun : IGun
GrenadeLauncher : IGun (More...)

What are the Authentication methods for your client object model application ?

  

Ans. Basically there are three (3) authentication options you can use when you're working with the Client Object Model in SharePoint 2010:

* Anonymous
* Default
* FormsAuthentication

You can specify clientContext.Authentication = Anonymous\Default\FormsAuthentication, If you do not choose an authentication method in your code, the application will default to using the client's Windows Credentials (DefaultCredentials). (More...)

What are basic methods of Data adapter?

  
Fill :- Executes the SelectCommand to fill the DataSet object with data from the data source. It an also be used to update (refresh) an existing table in a DataSet with changes made to the data in the original datasource if there is a primary key in the table in the DataSet.
FillSchema :- Uses the SelectCommand to extract just the schema for a table from the data source, and creates an empty table in the DataSet object with all the corresponding constraints.
Update:- Calls the respective InsertCommand, UpdateCommand, or DeleteCommand for each inserted, updated,or deleted row in the DataSet so as to update the original data source with the changes made to the content of the DataSet. This is a little like the UpdateBatch method provided by the ADO Recordset object, but in the DataSet it can be used to update more than one table. (More...)

What is Application Domain?

  
The primary purpose of the AppDomain is to isolate an application from other applications. Win32 processes provide isolation by having distinct memory address spaces. This is effective, but it is expensive and doesn't scale well. The .NET runtime enforces AppDomain isolation by keeping control over the use of memory - all memory in the AppDomain is managed by the .NET runtime, so the runtime can ensure that AppDomains do not access each other's memory.
Objects in different application domains communicate either by transporting copies of objects across application domain boundaries, or by using a proxy to exchange messages.
MarshalByRefObject is the base class for objects that communicate across application domain boundaries by exchanging messages using a proxy. Objects that do not inherit from MarshalByRefObject are implicitly marshal by value. When a remote application references a marshal by value object, a copy of the object is passed across application domain boundaries. (More...)
