What is Comman time system.

Posted By :Ashutosh Jha     Posted Date :December 27, 2013    Points :40   Category :.NET Framework 
Common Type System (CTS) describes the datatypes that can be used by managed code. CTS defines how these types are declared, used and managed at the runtime. It facilitates cross-language integration, type safety, and high performance code execution. The rules defined in CTS can be used to define your own classes and values.

What is JIT (just in time)? how it works?

  
Before Microsoft intermediate language (MSIL) can be executed, it must be converted by a .NET Framework just-in-time (JIT) compiler to native code, which is CPU-specific code that runs on the same computer architecture as the JIT compiler.
Rather than using time and memory to convert all the MSIL in a portable executable (PE) file to native code, it converts the MSIL as it is needed during execution and stores the resulting native code so that it is accessible for subsequent calls.
The runtime supplies another mode of compilation called install-time code generation. The install-time code generation mode converts MSIL to native code just as the regular JIT compiler does, but it converts larger units of code at a time, storing the resulting native code for use when the assembly is subsequently loaded and executed.
As part of compiling MSIL to native code, code must pass a verification process unless an administrator has established a security policy that allows code to bypass verification. Verification examines MSIL and metadata to find out whether the code can be determined to be type safe, which means that it is known to access only the memory locations it is authorized to access.

What is type system unification?

  
The goal of type system unification is to bridge the gap between value types and reference types that exists in most languages. For example, a Stack class can provide Push and Pop methods that take and return object values.

public class Stack
{
public object Pop() {...}
public void Push(object o) {...}
}
Because C# has a unified type system, the Stack class can be used with elements of any type, including value types like int. (More...)

What is the common type system (CTS)?

  
The common type system is a rich type system, built into the Common Language Runtime, that supports the types and operations found in most programming languages. The common type system supports the complete implementation of a wide range of programming languages. (More...)

What is a Database system?

  
The database and DBMS software together is called as Database system. (More...)

Disadvantage in File Processing System?

  
1.Data redundancy & inconsistency.
2.Difficult in accessing data.
3.Data isolation.
4.Data integrity.
5.Concurrent access is not possible.
6.Security Problems. (More...)

What is System R? What are its two major subsystems?

  
System R was designed and developed over a period of 1974-79 at IBM San Jose Research Center. It is a prototype and its purpose was to demonstrate that it is possible to build a Relational System that can be used in a real life environment to solve real life problems, with performance at least comparable to that of existing system.
Its two subsystems are
1.Research Storage
2.System Relational Data System. (More...)

How is the data structure of System R different from the relational structure?

  
Unlike Relational systems in System R
1.Domains are not supported
2.Enforcement of candidate key uniqueness is optional
3.Enforcement of entity integrity is optional
4.Referential integrity is not enforced (More...)

What is Record-at-a-time?

  
The Low level or Procedural DML can specify and retrieve each record from a set of records. This retrieve of a record is said to be Record-at-a-time. (More...)

What is Set-at-a-time or Set-oriented?

  
The High level or Non-procedural DML can specify and retrieve many records in a single DML statement. This retrieve of a record is said to be Set-at-a-time or Set-oriented. (More...)

Where is window Service Entries located in the system

  
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services (More...)

Where is GAC located in the system

  
Global Assembly Cache (GAC) Located in

C:\winnt\assembly

or

C:\windows\assembly (In Windows XP) (More...)

where is global assembly cache location in system?

  
The .NET Framework ships with a Windows shell extension for viewing the assembly cache. Navigating to % windir%\assembly with the Windows Explorer activates the viewer. (More...)
