The students copy the note in their books |
NOTE
FEATURES/CHARACTERISTICS OF EACH LEVEL OF PROGRAMMING LANGUAGE
i. These instructions consist of binary numbers (set of 0’s and 1’s)
ii. This language is machine dependent i.e. instructions written for a particular type of computer can only be executed on that particular machine.
iii. It is very hard for people to write and understand thus making the programs error prone.
iv. Each CPU design has its own machine language, which is the set of instructions that the CPU of that machine understands and executes.
i. Uses mnemonics (symbolic operation codes) and operands (symbolic storage address).
ii. Machine dependent
iii. For any assembly language instruction, one machine language instruction is generated.
iv. It illustrates fundamentals of computer construction and operation.
i. Machine independent: programs written or compiled on one type of Computer can be executed (run) on different type of computer that has different architecture.
ii. It uses instructions that seem English-like and thus closer to human understanding.
iii. Easy to detect errors
iv. Consists of well-defined syntax and standard.
v. Requires a compiler to translate into machine language before the computer can execute them.
vi. Programs written in HLL are called source code and the compiled version is called object code.

Does not require a translator |
Requires a translator called Assembler |
Requires a translator called a compiler or interpreter |
|
Instructions consist of binary digits (1’s and 0’s) |
Instructions consist of symbols and mnemonics |
Instructions consist of English-like words, symbols and numeric. |
EXAMPLES OF PROGRAMMING LANGUAGE
The following are some of the many programming languages:
Python, Ada, Algol, APL, BASIC, C, C++, C#, COBOL, FORTRAN, Java, JavaScript, LISP, Pascal, PHP, Perl, Python, Visual Basic etc
EVALUATION: 1. State the features of the each level of programming language
CLASSWORK: As in evaluation
CONCLUSION: The teacher commends the students positively
