1. Programming languages is:
      a. are the basic building blocks for all software, allowing people to tell computers
            what to do and the means by which systems are developed.

        b. A programming language or computer language is a standardized
            communication technique for expressing instructions to a computer. It is a set of
            syntactic and semantic rules used to define computer programs. A language
            enables a programmer to precisely specify what data a computer will act upon,
            how these data will be stored/transmitted, and precisely what actions to take
            under various circumstances

        c. An entity, in a program to be created and within this or also within other programs
            as a whole be processed can (eg to be created, copied, shifted, or changed can).



2. Compiler is:
     a. a computer program that translates a computer program written in one computer
            language (called the source language) into an equivalent program written in
            another computer language (called the output, object, or target language).

        b. A program which translates the source code for a library unit into an object
            module in a program library

        c. A program that translates a high-level language, such as Basic, into machine
            language

        d. A software-development tool that translates high-level language programs into
            the machine-language instructions that a particular processor can understand
            and execute. OCde optimisation reduce instructions number and specialize the
            code for a processor. These optimizations have to take into acount the processor
            architecture features.

        e. A program that translates a high level symbolic language to a low level machine
            language

3. Interpreter is:
       a. someone who mediates between speakers of different languages

        b. An interpreter is a computer program that executes other programs. This is in
            contrast to a compiler which does not execute its input program (the source
            code) but translates it into executable machine code (also called object code)
            which is output to a file for later execution. It may be possible to execute the
            same source code either directly by an interpreter or by compiling it and then
            executing the machine code produced

        c. An interpreter is a practitioner of interpreting, an activity that consists of
            establishing, either simultaneously or consecutively, oral or gestural
            communications between two or more speakers who are not speaking (or
            signing) the same language
4. Translator is:
      a. a person who translates written messages from one language to another

       b. a program that translates one programming language into another

       c. Translation is an activity comprising the interpretation of the meaning of a text in
           one language—the source text—and the production of a new, equivalent text in
           another language—called the target text, or the translation.



                   Five generation of programming languages

5. Machine language is:
     a. The lowest level language the computer understands. The computer converts all
           high-level languages, such as BASIC, into machine language before executing
           any statements. Machine language is written in binary form that a computer can
           execute directly. Also called machine code or object code.

       b. A language that can be used directly by the computer without intermediate
           processing

       c. A programming language that can be acted on (ie, executed) directly by the cpu.
           Also called a first generation language (1GL).

       d. The codes and format used by different machine manufactures within the
           embroidery industry. Common formats include Barudan, Brother, Fortran, Happy,
           Marco, Meistergram, Melco, Pfaff, Stellar, Tajima, Toyota, Ultramatic, and ZSK.
           Most digitized systems can save designs in these languages so the embroidery
           machine can read the computer disk.



6. Assembly language is:
      a. A programming language that is very similar to machine language, but uses
           symbols instead of binary numbers

       b. The lowest-level, and most difficult, language you can use to program a
           computer. Known as 2GL

       c. A symbolic form of computer language used to program computers at a
           fundamental level.

7. High level language is:
      a. a programming language where each instruction corresponds to several machine
           code instructions. Instructions in this language must be translated by a compiler
           or interpreter before they can be processed.
       b. A programming language whose statements are translated into more than one
           machine language instruction. Examples of high level languages are BASIC,
           FORTRAN, COBOL, and PASCAL.

       c. A high-level programming language is a programming language that is more
           user-friendly, to some extent platform-independent, and abstract from low-level
           computer processor operations such as memory accesses. See programming
           language for a detailed discussion. Aslo known as 3GL

8. Fourth generation language is:
      a. A language in which the code generation is computer assisted

       b. A fourth-generation programming language (or 4GL) is a programming language
           designed with a specific purpose in mind such as the development of commercial
           business software

9. Natural language is:
      a. A human language whose rules have evolved from current usage, as opposed to
           an artificial language whose rules are prescribed prior to its construction and use,
           as in the case of a computer language. In database searching, a natural
           language search allows the user to type words as input in the same way that a
           person normally speaks them

       b. Searching using everyday language, full sentences or questions

       c. Close to human language. Also known as 5GL


                             Programming languages approaches

10. Procedural approach is:
       a. A programming approach whereby the developer specifies exactly what must be
           done and in what sequence

       b. Synonym for algorithmic

11. Functional approach is:
       a. A programming paradigm that treats computation as the evaluation of
           mathematical functions.

12. Object-oriented approach is:
       a. A design methodology decomposing problems into objects rather than
           procedures. i.e. FORTRAN and C are procedural languages. C++ is a object-
           oriented language.

       b. A style of software development and packaging based on how real world objects
           relate to one another. Data and procedures are combined in objects; objects
           communicate with each other via messages; similar objects are grouped together
           into classes; data and procedures are inherited through a class hierarchy
