PRESENTATION ON

COMPUTER LANGUAGE

COMPUTER LANGUAGE IS THE LANGUAGE OF THE

COMPUTER. IT IS DIFFERENT FROM THE LANGUAGE

THAT WE USUALLY USE TO COMMUNICATE.

MACHINE CODE IS A COMPUTER LANGUAGE, WHICH

IS GIVEN IN A SERIES OF 0S AND 1S . IT IS A TINY

ELECTRONIC SWITCH THAT IS EITHER ‘ON’ OR ‘OFF’.

WHEN THE SWITCH IS ON, IT REPRESENTS 1 AND

WHEN THE SWITCH IS OFF, IT REPRESENTS 0. THE

USING OF ONLY TWO NUMBER IS CALLED AS BINARY

CODE. COMPUTER LANGUAGE IS DIVIDED INTO TWO

TYPES. THEY ARE:

1. HIGH LEVEL LANGUAGE (HLL)

2. LOW LEVEL LANGUAGE (LLL)

HIGH LEVEL LANGUAGE

* HIGH LEVEL LANGUAGE BRINGS THE

PROGRAMMING CLOSER TO HUMAN

LANGUAGE.

* HLL HAVE THEIR OWN PUNCTUATION

(SYNTAX) RULES WHICH ARE STRICTLY

OBSERVED.

* HLL ARE NEEDED TO BE CONVERT INTO

MACHINE LANGUAGE. THE CONVERSION

IS DONE BY A GROUP OF PROGRAMS AS

CALLED COMPILER.

ADVANTAGES OF HLL:-

1.IN HLL INSTRUCTIONS ARE EASY TO READ,

WRITE AND UNDERSTAND.

2.EASY TO UPDATE THE INSTRUCTION.

3.EASY TO REMEMBER THE ADDRESS SEQUENCE

OF INSTRUCTIONS.

4.EASY TO CONSTRUCT THE COMPLEX LOGIC

INSTRUCTION.

5.HLL ARE COMMON FOR ALL THE

MACHINES, SINCE IT IS MACHINE INDEPENDENT.

DISADVANTAGES OF HLL:-

1.PROCESSING SPEED IS TO SLOW.

2.IT OCCUPIES MORE MEMORY SPACE.

LOW LEVEL LANGUAGE

* THE ASSEMBLY LANGUAGE AND MACHINE

LANGUAGE ARE CONSIDERED TO BE LOW

LEVEL LANGUAGES.

* ASSEMBLY LANGUAGE IS A STEP ABOVE

THE MACHINE.

* CORRECT PROGRAMS ARE COMPILED AND

INTERPRETED TO LOW LEVEL LANGUAGE

AND EXECUTED BY THE COMPUTER.

ADVANTAGES OF LLL:-

1.PROCESSING SPEED IS HIGH BECAUSE IT IS ONE

TO ONE LANGUAGE.

2.TRANSLATION OF THE PROGRAM IS NOT

REQUIRED.

3.IT OCCUPIES LESS MEMORY SPACE.

DISADVANTAGE OF LLL:-

1.LLL INSTRUCTION ARE DIFFICULT TO READ,

WRITE AND UNDERSTAND.

2.DIFFICULT TO UPDATE THE INSTRUCTION.

3.DIFFICULT TO REMEMBER THE ADDRESS

SEQUENCE OF INSTRUCTION.

4.PROGRAMMING METHODOLOGY VERY FROM

MACHINE TO MACHINE.

5.ONLY SPECIALIST CAN BE ABLE TO OPERATE

THESE LANGUAGES.

CONCLUSION

THE ADVANCE COMPUTERS NOW NO LONGER

USES THE OLDER LANGUAGES FOR THEIR

OPERATION. IT HAS BEEN DEVELOPED AND

HAS BECOME MORE AND MORE USER

FRIENDLY.
