Study Notes
Assembler
- Translates mnemonic operation codes into machine code and symbolic addresses into machine addresses.
- Includes necessary linkages for closed subroutines and inserts appropriate machine code for macros.
- Allocates areas of storage and includes error codes if appropriate.
- Detects and indicates invalid source-language instructions.
- Produces the object program on tape or disk as required.
- Produces a printed listing of the source and object program with comments.
Compiler
- Translates high-level language into machine-oriented instructions.
- Generates the object program and produces a printed listing of the source and object programs when required.
- Translates the source-program statements into machine code.
Features of High-Level Language
- Similar to English with vocabularies of words and symbols.
- Easy to learn and use.
Machine Independent Programming Language
- Used to write business application programs.
- Designed to be easily learned and used by end-users.
- Allows users to create programs without the need for a programmer.
- Examples include report generators, application generators, and query languages.
Natural Programming Language
- Represents a natural language.
- Eliminates the need for users to learn a specific vocabulary, grammar, or syntax.
- Text of a natural language statement resembles human speech.
- Examples include Clones for Microcomputers and Intellect for Mainframes.
Expert Systems and Artificial Intelligence
- Use of artificial intelligence touches on expert systems.
- Expert systems use a computerized collection of the knowledge of many human experts.
- Artificial intelligence is an independently smart computer system.
