Explain Difference Between Compiler and Interpreter

Difference between Compiler and Interpreter

The Compiler and Interpreter are the two main types of Language Translator or Language Processor
Explain differences between compiler and interpreter in detail
Explain some important differences between Compiler and Interpreter


or Differentiate between Interpreter and Compiler


Compiler                                    Interpreter                             
1.    Compiler   converts   a   source program   into machine code as a whole.                                 1.  Interpreter    converts    a    source program    into machine code one statement at a time.           
2. Compiler after translating whole source program, creates object code file, that can be executed.   2. Interpreter does not create object code file. It only creates executable code for only one statement currently interpreted, which is executed. Next time second statement is translated and executed and so on. No object file is created.
3. Program execution is fast. Since once program is compiled successfully, an object code file is produced. Now this object code file is executed. No need of re-compilation unless we change the source code.

                      		 3. Program execution is slow. Because every time we want to run a program it is interpreted again.                         
4. Error detection and error removal is comparatively difficult. Because, compiler will show a list of all errors in the whole program. Therefore, sorting out every error individually and removing the cause of error becomes more difficult and time consuming.
                   		 4. Error detection and removing error is easy in case of interpreter, because interpreter will show when error at a time and its location in program. So that the programmer can easily catch and remove error.                           
5. More programming languages use compilers for translating source code to object code. 5. The number of high level programming languages that use Interpreter as an option to translate source code into object code is relatively smaller.
6. In compiled high level programming languages program execution does not require Translator or compiler for every execution. Because after first time of compilation, object code file is available that is used subsequently for onward program executions unless we change the source code. In case of change of source code, we need to re-compile the source code to show changes in the object code also. 6. In interpreted high level programming languages, translator program is needed every time for execution of the source program.

Introduction to Algorithms and Algorithmic Notation With Examples

Topic: Introduction to Algorithm and Algorithmic Notation With Examples What is an Algorithm? The step by step procedure to solve a particular problem is called an Algorithm .  A Good Programmer always writes algorithms before developing programs. Algorithmic Notation with example algorithms  Advantages of  writing an Algorithm The process of solving a problem becomes simpler and easier with the help of  algorithm. There are less chance of errors in the program, if we design algorithms before writing our programs in any programming language. We can convert an algorithm into a program of any programming language. It is not dependent on any programming language. Therefore it is easy to understand for anyone even without programming knowledge. What is the Relationship between an Algorithm and a Program Sponsored Links An algorithm is the sequenc of steps to perform a task, whereas a program is the set of statements to perfor...

Define Data and Information With Examples

DATA Data is the collection of raw facts and figures. Actually data is unprocessed, that is why data is called collection of raw facts and figures. Define Data and Information with Examples We collect data from different resources. After collection, data is entered into computer for processing. Data may be collection of words, numbers, pictures,  or sounds etc. Examples of Data 1) Student Data on Admission Forms When students get admission in a college. They fill admission form. This form  contains raw facts (data of student) like name, father’s name, address of student, obtained marks, photo graph etc. 2)    Data of Citizens During census, data of all citizens is collected. The staff will go house to house and collect data about citizens like number of persons living in a home, either they are literate or illiterate, number of children, data of each child, cast, religion, Computerized national Identity Card number, address, how many rooms and...

What are Dual Devices or Both Input/ Output Devices

The devices that can be used to perform both functions -input and output- are called Dual Devices. These devices are also called Dual Purpose Devices or Both Input/Output Devices. With the help of a dual purpose device, we can enter data into computer as well as we can output data from the computer to outside world.  For example, Dual devices include:  Touch Screen Monitor, Modem, Network Interface Card, Sound card, Hard disk drive, Floppy disk Drive, Magnetic Tape Drive CD-Writer and DVD-Writer etc. These are also called Input/output devices, because they perform both functions. Touch Screen Monitor Dual Devices or Both Input / Output Devices - Touch screens Touch Screen Monitor is an input/output device. It uses a special touch sensitive screen. The User can enter data by touching icons or menus on the screen. As soon as the user selects a command from menu, output is displayed on screen. Commonly touch screen monitors use sensors to detect touch of finger. ...
