Answer:
1. COBOL: Common Business-Oriented Language
2. Assembly language is based on machine code.
3. Stat: Statistical Analysis System
4. SQL: Structured Query Language
5. Decimal: Decimal number system consists of 10 digits.
Mnemonic codes: Mnemonic codes are used to represent instructions or data in a more human-readable format, making it easier for programmers to remember and understand. Examples of mnemonic codes include ADD (addition), SUB (subtraction), and MOV (move). They are commonly used in assembly language programming.
Compiler: A compiler is a language processor that translates high-level programming code into machine code, which can be directly executed by a computer. It performs various tasks such as syntax analysis, optimization, and code generation.
High-level language: A high-level language is a programming language that is designed to be easier for humans to read, write, and understand. It provides a higher level of abstraction and is closer to natural language compared to low-level languages like assembly or machine code.
Fifth-generation language: A fifth-generation language (5GL) is a programming language that focuses on artificial intelligence and problem-solving using a high-level, declarative approach. It allows programmers to specify what needs to be done rather than how to do it. Examples of 5GLs include Prolog and OPS5.
