- 1. FEATURES OF VARIOUS COMPUTER LANGUAGES • SUBMITTED BY: CHARANPREET SINGH • ROLL NO. : 7 • CLASS : 6TH
- 2. LANGUAGE Human Language: Commonly used to express Feeing and understand other person expression. It can be oral or gestural kind of Communication.
- 3. DEFINITION OF COMPUTER LANGUAGES • 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. Lower Level Language A low-level programming language is a programming language that provides little or no abstraction from a computer's instruction set architecture. It consists of numeric codes i.e 0 & 1. These codes are easily understandable to computer but difficult to human.. A lower level language is used in two generations of computer. •first generation •second generation
- 5. CHARACTERSTICS OF LOW LEVEL LANGUAGES • Direct memory management • Little-to-no abstraction from the hardware • Register access • Statements usually have an obvious correspondence with clock cycles • Superb performance
- 6. Advantages •Computational Speed is very fast. •Directly understandable by computer. Disadvantages •Development of a program in machine language is very time consuming. •Error correction is tedious process.
- 7. HIGH LEVEL LANGUAGES • High-level programming languages allow the specification of a problem solution in terms closer to those used by human beings. These languages were designed to make programming far easier, less error- prone and to remove the programmer from having to know the details of the internal structure of a particular computer. This language is used in third generation.
- 8. TYPES • C++ • VISUAL BASIC • JAVA • JAVASCRIPT
- 9. CHARACTERSTICS • Interpreted • Dynamic constructs (open classes, message- style methods, etc) • Poor performance • Concise code • Flexible syntax (good for internal DSLs)
- 10. Advantages •These are simple to adopt due to their english like structure of statements. •They are easy to maintain and debug. Disadvantages •The Program written in high level language are less efficient as they take more execution time. •The compiler also consumes some memory as it is required for the translation process.
