    • Programming languages Low level languages(LLL) High level languages(HLL) Machine level languages Assembly languages
    • HIGH LEVEL High level programming Languages are closer to English and thus easier to Learn but slower than Machine level languages. ASSEMBLY LEVEL uses coadings MACHINE LEVEL It is the language spoken by computer
    • LOW LEVEL LANGUAGES • Machine oriented languages • Cannot be used easily on other computers.
    • Machine level languages • Language which uses binary digits
    • Assembly level languages • These languages use letters and symbols instead of binary digits. • They are translated into machine level languages
    • High level languages • Easier to understand • Not dependent on any particular computer machine
    • ADVANTAGES OF HLL • Understandability • Debugging • Portability
    • EXAMPLES OF HLL • • • • • • • • BASIC LOGO FORTRAN COBOL PASCAL C C++ JAVA
