ii. Computer programming language – meaning, example (Logo, BASIC etc)
Meaning of computer program
A set of instructions to the computer to perform a specific task written in a specific programming language is called computer program.
Meaning of programming language
A programming language is the language in which a computer programmer writes the instructions which a computer should follow in solving a given problem.
A programmer is someone who writes instructions for computer to perform a specific task. Programming is the act of writing instructions for computer to perform a specific task. A computer person that writes a set of instructions for the computer to obey is referred to as computer programmer.
The three main categories of programming languages are:
1. Machine language
2. Low level language
3. High level language
Machine Language
A language in which the computer performs the instructions immediately without any further transaction is called machine language. The machine language is the computer primary language. It is the only language that the computer understands and does not require interpretation. It is usually written in the forms of… Click here to order the complete second term Computer Science Lesson Note for JSS2

Meaning of BASIC
BASIC stands for Beginner All-purpose Symbolic Instruction Code. It is not only simple but also a very powerful high level programming language. It consists of statements written in English words and mathematical notation. It is written in a human understandable form. Its syntax is close to the natural way of solving some human problems.
Rules for BASIC programming
1. All expressions must be written in capital letters.
2. First character must be alphabet
3. BASIC statement or keyword must start with a line number.
4. Each line must contain only one BASIC program statement.
5. There must not be full stop at the end of a statement.
