1. COMPUTER PROGRAM
1.1. A computer program is a list of instruction that tell what computer to do
2. COMPUTER LANGUAGE
2.1. A programming language is a vocabulary and set of grammatical rules for instructing a computer or computing device to perform specific tasks. It includes rules , syntax,numerical,logical operators and utility functions.
3. PROGRAMMING LANGUAGE
3.1. 1. MACHINE LANGUAGE 2.Assembly Language 3.High level Language
4. INTERPRETER
4.1. Translates program one statement at a time.It takes less amount of time to analyze the source code but the overall execution time is slower.No intermediate object code is generated, hence are memory efficient.Continues translating the program until the first error is met, in which case it stops. Hence debugging is easy.
5. COMPILER
5.1. Scans the entire program and translates it as a whole into machine code.It takes large amount of time to analyze the source code but the overall execution time is comparatively faster.Generates intermediate object code which further requires linking, hence requires more memory.
