What is SLIP (Serial Line Interface Protocol)?

Posted By :Abhisek Panda     Posted Date :January 21, 2010    Points :10   Category :Networking 
It is a very simple protocol used for transmission of IP datagrams across a serial line.

SMDS Interface Protocol (SIP)?

1. Connectionless service.

3. Used for communication between CPE and SMDS carrier equipment.

4. Based on IEEE 802.6 Distributed Queue Dual Bus (DQDB) standards .

5. Consists of three levels:
SIP Level 3
SIP Level 2
SIP Level 1 (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 a protocol class?

An abstract class is a protocol class if:
. it neither contains nor inherits from classes that contain member data, non-virtual functions, or private (or protected) members of any kind.
. it has a non-inline virtual destructor defined with an empty implementation,
. all member functions other than the destructor including inherited functions, are declared pure virtual functions and left undefined. (More...)

What is difference between interface inheritance and class inheritance?

We can only inherit from one class but multiple interfaces. In addition, an interface does not contain any implementation it just contains a series of signatures. (More...)

What is difference between abstract class and an interface?

An Abstract class is a class with some common/certain implementations and defines abstraction for other services which are implemented in its concrete sub classes, whereas interface only have method declaration with zero implementations. An abstract class and Interface both have method only but not have body of method. The difference between Abstract class and An Interface is that if u call Abstract class then u have to call all method of that particular Abstract class but if u call an Interface then it is not necessary that u call all method of that particular interface. An abstract class is a special kind of class that cannot be instantiated. So the question is why we need a class that cannot be instantiated? An abstract class is only to be sub-classed (inherited from). In other words, it only allows other classes to inherit from it but cannot be instantiated. The advantage is that it enforces certain hierarchies for all the subclasses. In simple words, it is a kind of contract that forces all the subclasses to carry on the same hierarchies or standards.

An interface is not a class. It is an entity that is defined by the word Interface. An interface has no implementation; it only has the signature or in other words, just the definition of the methods without the body. As one of the similarities to Abstract class, it is a contract that is used to define hierarchies for all subclasses or it defines specific set of methods and their arguments. The main difference between them is that a class can implement more than one interface but can only inherit from one abstract class. Since C# doesn't support multiple inheritance, interfaces are used to implement multiple inheritance.

What is the Transport Protocol you use to call a Web Service ?

Can you describe IUKNOWN interface in short ?

Every COM object supports at least one interface, the IUnknown interface. All interfaces are classes derived from the base class IUnknown. Each interface supports methods access data and perform operations transparently to the programmer. For example, IUnknown supports three methods, AddRef, Release(), and QueryInterface(). Suppose that pinterf is a pointer to an IUnknown. pinterf->AddRef() increments the reference count. pinterf->Release() decrements the reference count, deleting the object when the reference count reaches zero. pinterf->QueryInterface( IDesired, pDesired) checks to see if the current interface (IUnknown) supports another interface, IDesired, creates an instance (via a call to CoCreateInstance()) of the object if the reference count is zero (the object does not yet exist), and then calls pDesired->AddRef() to increment the reference count (where pDesired is a pointer to IDesired) and returns the pointer to the caller.

Yes, from the standard toolbar select Tools | Options.This will open the Options dialog; select the Text Editor folder, pick the language, and click on the check box for line numbering under the display section. (More...)
