Translators & Utility Programs
What are Translators?
Translators are used for translating or converting, any input to the computer, into strings of bits so that it can become meaningful to the computer.
Translators can take the form of:
a. Compiler: This undertakes the translation of the whole program into a machine-readable form.
b. Interpreter: This translates the instruction to the program line by line.
c. Assembler: This handles programs written in a low-level language.
Translators are used in writing other software and computer programs. For example:
FORTRAN: Formula Translation.
COBOL: Commercial Business Oriented Language.
BASIC: Beginners All-Purpose Symbolic Instruction Code.
What are Utility Programs?
These are the system programs that assist the user of the computer, to efficiently use the available hardware resources, like the operating system.
Utility programs also come with the system and are used to perform the following functions: file copying, sorting, deletion, creation, updating, etc.
