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.

Explain Main Difference Between System Software and Application Software

Topic: Explain Main Difference Between System Software and Application Software            Differentiate between system software and application software Before , explaining the main differences between application software and system software, let us know the definitions of Application software and System software with examples. What is System Software: System software is a set of programs to control all components of computer and to manage overall operations of computer system. Differences between System software and application software System software is used as a base to install and run all application software. Examples of system software include: Operating Systems, like Microsoft Windows, DOS, Unix and Linux Device Drivers like Device driver software of a Printer (found on CD normally provided with the printer) Utility Programs like AVAST anti virus, Disk Scanners and File Viewers etc. What is Applicat...

Explain different types of storage devices

Topic: Explain different types of storage devices in Computer systems Storage Devices Storage devices are used to store data and instructions permanently. Storage devices are also called secondary storage devices / backing storage devices / external storage devices or auxiliary storage devices. Examples of storage devices include Hard Disk, CD and DVD etc. Why Secondary Storage Devices are Used? Secondary storage devices are used because: Primary memory(RAM) is volatile and temporary. When computer is switched off, all data in ram is erased. Storage devices can store large amounts of data and instructions permanently whereas Primary memory has less capacity of storing data. Types Of Storage Devices There are three main types of storage devices:  Magnetic Tape   Magnetic Disk   Optical Disk   Flash Memory storage devices 1. Magnetic Tape Magnetic tape is the oldest storage device. It is made of plastic coated with m...

Different Functions Of Operating Systems

Topic: Different Functions Of Operating Systems What is an Operating System? Operating systems are an important type of system software. They provide a lot of facilities to the users. An operating system can be defined as software that acts as an interface between the end user and the hardware. Computer users can use computer systems that have an OS or operating system installed. For example, Microsoft Windows is a popular PC operating system. What is the Importance of Operating System in Computer? Each computer must have at least one operating system to run other programs. for example, if there is no operating system in your computer, you will not be able to use the computer. When you install an OS like Microsoft Windows on your computer, it displays its GUI that is Windows desktop on startup. Now you can use your computer with the help of graphical user interface elements like icons, menus, shortcuts on your computer screen. Similarly if you wish to install application ...
