What is the difference between a web-garden and a web-farm?

Posted By :Ghanashyam Nayak     Posted Date :September 11, 2010    Points :10   Category :JavaScript/VBScript 
Web garden is a web hosting system. It is a setup of multi processors in single server.



Web farm is a web hosting system. It is a multi-server scenario.

difference between web farm and web garden

  
webfarm is a multiple server scenario whereas webgarden is a multiple process scenario.
in webfarm we have server in each and every place.if one crashes or load excessively the other burnt or fails.so there arise a situation to load the balance between the multiple servers.
various modes of bearing the balance are:

A)ROUND ROBIN(ALL SERVERS LOAD BALANCE EQUALLY)
B)NLB
C)HLB
D)HYBRID (More...)

What is the difference between a web-garden and a web-farm?

  
Web-garden - An IIS6.0 feature where you can configure an application pool as a web-garden and also specify the number of worker processes for that pool. It can help improve performance in some cases.
Web-farm - a general term referring to a cluster of physically separate machines, each running a web-server for scalability and performance (contrast this with web-garden which refers to multiple processes on one single physical machine). (More...)

Difference between sandbox solution and farm solution

  
SharePoint 2010 introduces new feature sandbox solution.Here are major difference between sandbox solution and farm solution.

1.The scope of sandbox solution is site collection where as The scope of farm level solution is farm level.

2.Sandboxed solutions, which are hosted in the SharePoint user code solution worker process (SPUCWorkerProcess.exe)Whereas Sandboxed solutions, which are hosted in the SharePoint user code solution worker process (SPUCWorkerProcess.exe)

3.Sandbox run code that can only affect the site collection of the solution.The process runs under a CAS policy that restricts programmatic access to any resource outside the sandbox.Whereas Farm Solution run code that can affect the whole farm.

4.Sandbox Never restart the IIS application pool.If you run any code it will affect only the site collection of the solution. Whereas If you deploy any feature or retract any feature the whole application pool got recycled in farm solution.

5.Sandboxed solutions are uploaded and activated whereas Farm solutions are installed and deployed.

6.we can’t create VISUAL web parts in Sandbox solutions whereas VISUAL web parts can be created in farm solution.

7.When the Sandboxed Solution property is set to True, selecting Build\Deploy Solution deploys the solution to the site collection Solution Gallery.whereas When the Sandboxed Solution property is set to False, selecting Build\Deploy will deploy the solution to the Farm Solution Gallery. (More...)

Difference Between Delete and Truncate

  
.Delete table is a logged operation, so the deletion of each row gets logged in the transaction log, which makes it slow.

. Truncate table also deletes all the rows in a table, but it won't log the deletion of each row, instead it logs the de-allocation of the data pages of the table, which makes it faster. Of course, truncate table cannot be rolled back.

. Truncate table is functionally identical to delete statement with no "where clause" both remove all rows in the table. But truncate table is faster and uses fewer system and transaction log resources than delete.

. Truncate table removes all rows from a table, but the table structure and its columns, constraints, indexes etc., remains as it is.

. In truncate table the counter used by an identity column for new rows is reset to the seed for the column.

. If you want to retain the identity counter, use delete statement instead.

. If you want to remove table definition and its data, use the drop table statement.

. You cannot use truncate table on a table referenced by a foreign key constraint; instead, use delete statement without a where clause. Because truncate table is not logged, it cannot activate a trigger.

. Truncate table may not be used on tables participating in an indexed view. (More...)

Difference between assembly manifest & metadata?

  
assembly manifest - An integral part of every assembly that renders the assembly self-describing. The assembly manifest contains the assembly's metadata. The manifest establishes the assembly identity, specifies the files that make up the assembly implementation, specifies the types and resources that make up the assembly, itemizes the compile-time dependencies on other assemblies, and specifies the set of permissions required for the assembly to run properly. This information is used at run time to resolve references, enforce version binding policy, and validate the integrity of loaded assemblies. The self-describing nature of assemblies also helps makes zero-impact install and XCOPY deployment feasible.

metadata - Information that describes every element managed by the common language runtime: an assembly, loadable file, type, method, and so on. This can include information required for debugging and garbage collection, as well as security attributes, marshaling data, extended class and member definitions, version binding, and other information required by the runtime. (More...)

What is the difference between ref & out parameters?

  
An argument passed to a ref parameter must first be initialized. Compare this to an out parameter, whose argument does not have to be explicitly initialized before being passed to an out parameter. (More...)

What is the difference between a Struct and a Class?

  
The struct type is suitable for representing lightweight objects such as Point, Rectangle, and Color. Although it is possible to represent a point as a class, a struct is more efficient in some scenarios. For example, if you declare an array of 1000 Point objects, you will allocate additional memory for referencing each object. In this case, the struct is less expensive.

When you create a struct object using the new operator, it gets created and the appropriate constructor is called. Unlike classes, structs can be instantiated without using the new operator. If you do not use new, the fields will remain unassigned and the object cannot be used until all of the fields are initialized.

It is an error to declare a default (parameterless) constructor for a struct. A default constructor is always provided to initialize the struct members to their default values.

It is an error to initialize an instance field in a struct.

There is no inheritance for structs as there is for classes. A struct cannot inherit from another struct or class, and it cannot be the base of a class. Structs, however, inherit from the base class Object. A struct can implement interfaces, and it does that exactly as classes do.

A struct is a value type, while a class is a reference type. (More...)

Difference between type constructor and instance constructor? What is static constructor, when it will be fired? And what is its use?

  
(Class constructor method is also known as type constructor or type initializer)
Instance constructor is executed when a new instance of type is created and the class constructor is executed after the type is loaded and before any one of the type members is accessed. (It will get executed only 1st time, when we call any static methods/fields in the same class.) Class constructors are used for static field initialization. Only one class constructor per type is permitted, and it cannot use the vararg (variable argument) calling convention. (More...)

What is the difference between Finalize and Dispose (Garbage collection)

  
Class instances often encapsulate control over resources that are not managed by the runtime, such as window handles (HWND), database connections, and so on. Therefore, you should provide both an explicit and an implicit way to free those resources. Provide implicit control by implementing the protected Finalize Method on an object (destructor syntax in C# and the Managed Extensions for C++). The garbage collector calls this method at some point after there are no longer any valid references to the object.
In some cases, you might want to provide programmers using an object with the ability to explicitly release these external resources before the garbage collector frees the object. If an external resource is scarce or expensive, better performance can be achieved if the programmer explicitly releases resources when they are no longer being used. To provide explicit control, implement the Dispose method provided by the IDisposable Interface. The consumer of the object should call this method when it is done using the object. Dispose can be called even if other references to the object are alive.


Note that even when you provide explicit control by way of Dispose, you should provide implicit cleanup using the Finalize method. Finalize provides a backup to prevent resources from permanently leaking if the programmer fails to call Dispose. (More...)

Difference between OLEDB Provider and SqlClient ?

  
SQLClient .NET classes are highly optimized for the .net / sqlserver combination and achieve optimal results. The SqlClient data provider is fast. It's faster than the Oracle provider, and faster than accessing database via the OleDb layer. It's faster because it accesses the native library (which automatically gives you better performance), and it was written with lots of help from the SQL Server team. (More...)

What is the difference between interface and abstract class ?

  
a class may inherit several interfaces, a class may inherit only one abstract class (More...)

What is the Difference between #Bind and #Eval ?

  
Eval is read only. Bind is 2 way binding(updatable) (More...)

What is the difference between ViewState and SessionState?

  
ViewState persist the values of controls of particular page in the client when post back operation done. When user requests another page previous page data no longer available.

SessionState persist the data of particular user in the server. This data available till user close the browser or session time completes. (More...)
