- 2. Language Human Language: Commonly used to express Feeing and understand other person expression. It can be oral or gestural kind of Communication.
- 3. Computer Language A computer languages are the languages by which a user command a computer to work on the algorithm which a user has written to get an output. TWO TYPES OF COMPUTER LANGUAGES Low-level languages High-level languages
- 4. Architecture
- 5. High level language A type of language that is close to human languages is called high level language. High level language are easy to understand instructions of these language are written in English _like words such as input and print etc. EXAMPLES Basic. Fortran C/C++ Java Visual Basic Comol.
- 6. Advantages of High level language They are near to English language, that is they are easier to read, write and maintain. High-level languages make complex programming simpler. High level languages is portable, i.e., they can work on different operating system. Length of the program is also small compared with low level. Many real time problems can be easily solved with high level language.
- 7. Disadvantages of High level language Translation Time: High-level languages require an additional step to translate the human-readable source code into machine- executable instructions. Slower Execution: Compared to low-level languages (like assembly or binary), programs written in high-level languages tend to run more slowly.
- 8. Low level language Low level language are near to computer hardware and far from human languages. Assembly language is the best example of low level language, it is in between machine language and high-level language. A low-level language does not need a compiler or interpreter to run the program, the processor run low-level code directly.
- 9. Example of low level code &machine Language
- 10. Advantages of low level language Programs developed using low level languages are fast and memory efficient Programmers can utilize processor and memory in better way using a low level language It can directly communicate with hardware devices. DISADVANTAGES It is difficult to develop, debug and maintain. Low level programs are more error prone.
- 11. Program code converters There are four models of execution of program by processor in high- level languages INTERPRETER COMPILER ASSEMBLER TRANSLATORS
