Technology Questions

.NET Framework provides enormous advantages to software developers in comparison to the advantages provided by other platforms. Microsoft has united various modern as well as existing technologies of software development in .NET Framework. These technologies are used by developers to develop highly efficient applications for modern as well as future business needs. The following are the key components of .NET Framework:

 =>   .NET Framework Class Library
 =>   Common Language Runtime
 =>   Dynamic Language Runtimes (DLR)
 =>   Application Domains
 =>   Runtime Host
 =>   Common Type System
 =>   Metadata and Self-Describing Components
 =>   Cross-Language Interoperability
 =>  .NET Framework Security
 =>   Profiling
 =>   Side-by-Side Execution

The object need to be serialized when it’s sent over a network and when it’s state is saved. Exceptions which occur during serialization are:

a. transient fields

b. when the base class is serialized then only base class fields are handled.

c. static fields are ignored because they are not part of any state.

Walkthrogh: Very informal type of review or testing method. Done by peers, so its called peer review.

Inspection: very technical type of review or testing method, done by the highly technically sound people.

A scheduling agreement can be made for Consignment, Subcontracting and stock transfer. A contract, also known as a blanket PO, can be made for standard items and can be restricted to a Value or QTY.

1. Have two indexes pointing to two ends of array, say i and j.

2. Approach towards each other with a check condition that they dont cross each other.

3. Each iteration of while loop, swap the numbers pointed by two indexes when num[i] index number is not equal to 1.

void sort()

{

     int a[]={1,0,0,0,1,1,0,1,0,1,0,0,1,0};

     int i=0;

     int j=13;

     int temp;

      while(j>i)

     {

          if(a[i]==1)

                 i++;

          if(a[j]==0)

                 j--;

          if(a[i]==0)

         {

                 temp=a[i];

                a[i]=a[j];

                a[j]=temp;

         }

     } 

     for(i=0;i<14;i++)

             Console.Write(a[i]+", ");

}

Output: 1,1,1,1,1,1,0,0,0,0,0,0,0

- Web browser supports HTTP secure method that allows more security for the sites that are involved in day to day basis transaction. 

- Security offers quick and easy way to remove the unwanted material or the things that are stored without permission like cache, cookies and history. 

- Security is being provided by the use of blockers that blocks unwanted access to the websites from the outside. 

- Web browser uses other features like disabling of JavaScript and pop up blockers to block any unwanted scripts or messages to run on the system.

- Web browser also uses the security concerns in regard of blocking the access to the secure sites that provides money transfer facilities, etc.

The Singleton design pattern ensures a class only has one instance, and provides a global point of access to it. The class keeps track of its sole instance and ensures that no other instance can be created. Singleton classes are appropriate for situations where it makes sense for a single object to provide access to a global resource.Several Cocoa framework classes are singletons. They includeNSFileManager, NSWorkspace, NSApplication, and, in UIKit,UIApplication. A process is limited to one instance of these classes. When a client asks the class for an instance, it gets a shared instance, which is lazily created upon the first request.
