Introduction:

The purpose of this article is to provide the reader with a fast and simple introduction to using
the Linux command shell and some of its basic utilities. It is assumed that the reader has zero or
very limited exposure to the Linux command prompt.

A brief article on Testing.

INTRODUCTION:

Software testing is a critical element of software quality assurance and represents the ultimate review of specification, design and coding. In fact, testing is the one step in the software engineering process that could be viewed as destructive rather than constructive.

A strategy for software testing integrates software test case design methods into a well-planned series of steps that result in the successful construction of software.The underlying motivation of program testing

History and features of JAVA

In November 1995, Sun Microsystems introduced a new programming language to the world- Java. Until then the word “Java” could only mean an island in Indonesia or a particular blend of coffee. 

Though its initial development began as early as 1991, it took some time for the final working version to reach the market. The basic objective behind developing the language was to create software that could be embedded in consumer electronic devices. Efforts were taken to produce a portable, platform in dependable language, and the result of this led to the birth of a new language. James Gosling

Testing and Integration

INTRODUCTION

After completing the coding part according to the requirement, we have to test the quality of the software. Software testing is an empirical technical investigation conducted to provide stakeholders with information about the quality of the product. Testing is the process of executing a program or application with the intent of finding errors. Problem with software testing is that number of defects in a software product can be very large and defects that occur infrequently are difficult to find in testing. It is commonly believed that the earlier a defect is found the cheaper it is to fix it.

CLR Common Language Runtime Execution model.

Compilation and Execution of a .NET Application When you compile a .NET application, it is not compiled to binary machine code; rather, it is converted to IL. This is the form that your deployed application takes—one or more assemblies consisting of executable files and DLL files in IL form. At least one of these assemblies will contain an executable file that has been designated as the entry point for the application.

When execution of your program begins, the first assembly is loaded into memory. At this point, the common language runtime examines the assembly manifest and determines the requirements to run the program. 

Dot Net Framework Architecture, Overview

To understand how the common language runtime manages code execution, you must examine the structure of a .NET application. The primary unit of a .NET application is the assembly. An assembly is a self-describing collection of code, resources, and metadata. The assembly manifest contains information about what is contained within the assembly. The assembly manifest provides:

Object-Oriented Programming OOP

Introduction to Object-Oriented Programming:

Programming in the .NET Framework environment is done with objects. Objects are programmatic constructs that represent packages of related data and functionality. Objects are self-contained and expose specific functionality to the rest of the application environment without detailing the inner workings of the object itself. Objects are created from a template called a class. The .NET base class library provides a set of classes from which you can create objects in your applications. You also can use the Microsoft Visual Studio programming environment to create your own classes.
