Compiler and Interpreter

-

We generally write a computer program using a high-level language. A high-level language is one that is understandable by us, humans. This is called source code.

However, a computer does not understand high-level language. It only understands the program written in 0's and 1's in binary, called the machine code.

To convert source code into machine code, we use either a Compiler or an Interpreter.


 Compilers and Interpreters are used to convert a program written in a high-level language(Java,Python) into machine(Binary code 0,1) code understood by computers. 


Differences Between Interpreter and Compiler :

Interpreter :

1- Programming languages like                    JavaScript, Python, Ruby use                      interpreters.

2- There is not intermediate object                code  generated, hence are memory        efficient.

3- Interpreters  take less  time to                    analyze the source code. However,          the overall execution   time is                    comparatively slower than                        compilers.    

Compiler :

1-  Scan the entire program and translates it as a all into machine code.

2- Programming languages like C, C++, Java use compilers.

3- Compiler generates intermediate object  which  requires linking, hence take more                  memory.

What is Java

  Java is a   programming language  and a  platform .Java is a high level, robust, object-oriented and secure programming language.   Java was developed by  Sun Microsystems  (which is now the subsidiary of Oracle ) in the year 1995. Before that the research of Java started in 1990,  James Gosling   is known as the father of Java. Before Java, its name was  Oak . Oak was name of big tree so this name was not suitable for technical Language name ,They this about java name but that name was already register by a coffee company name so they told the owner of java company name that they want to use that name so owner of java company was said you have to put my coffee logo to your product   so James Gosling and his team changed the Oak name to Java. Platform : Any hardware or software environment in which a program runs, is known as a platform. Since Java has a runtime environment JVM and  (JRE) and API, it is called pla...

What is Python

  Python  is a general purpose, dynamic, high-level , and interpreted programming language. It supports Object Oriented programming approach to develop applications. Python's syntax and  dynamic typing  with its interpreted nature make it an ideal language for scripting and rapid application development. Python supports  multiple programming pattern , including object-oriented,  functional and procedural programming styles.  That is why it is known as  multipurpose  programming language because it can be used with web, enterprise, 3D CAD, etc. Python makes the development and debugging  fast  because there is no compilation step included in Python development . Python Features : There are many features listed below  Expressive Language :    It  can perform complex tasks using a few lines of code. A simple example, the hello world program you simply type  print("Hello World") . It will take only one line to...

Digital Marketing is determined by the usage of many digital tactics and communications to interact with customers where they spend more of their time: Online. From this site itself to the sector's on-line branding assets -- digital advertising, e-mail selling, online brochures, and beyond  there's the range of tactics that come under the umbrella of `` digital marketing.

Research indicates that 30 minutes or less is how far consumers typically spend absorbing digital selling knowledge. That is the situation today's marketers are confronting with their varied user habits and expectations.  The internet is a powerful tool for reaching out to consumers in ways that are not possible through traditional media. However, as we have seen in recent years, the use of social media has also been a key factor in driving consumer behavior. This study will examine the ...
