                 Programming Software

                 It is the software used by the computer to understand and convert the instructions by
                 programming  language  into machine language.  Compilers,  assemblers,  debuggers,
                 interpreters, etc. are examples of programming software.

                 Assembler

                 An assembler is a program used to translate assembly language into machine language
                 so that the computer can understand it.

                 Compiler
                 A  compiler  is  a  software  that  converts  the  entire  source  program  into  machine
                 language before executing it. It displays the errors for the whole program together.

                 Interpreter

                 An  interpreter is also a  separate  program that  converts  the  entire  source  program
                 into machine language before executing it. An interpreter translates and executes one
                 statement at a time. It displays the errors in one line at a time and it goes to the next line
                 only after the error is corrected.


                    Info Byte
                     Programming  and  Computer  Software,  founded  in 1975,  is devoted  to  provide
                     solutions to problems in all areas of computer science: operating systems, compiler
                     technology, software engineering, artificial intelligence, etc.




                 Utility Software

                 Utility software are provided as a part of the operating system. They are specifically designed
                 to manage the computer hardware, operating system and application software. Some of
                 the utility softwares are:


                 Backup Utility

                 It is used for keeping the backup files for emergency. Windows Backup and Restore is the
                 default Windows backup utility.

                 Data Compression Program

                 It is used to compress a large file into a file of smaller
                 size so that it occupies less space and is easy to store.
                 Winzip and Winrar are examples of this software.
