Computer Programming Languages

MAIN AIM:  To help the students understand what programming language is.

SUBSIDIARY AIMS: By the end of the lesson, the students should be able to;

• Define Programming Language,
• State and explain the types of programming Language,
• Examples of High-level language.

PERSONAL AIM: To assist the students understand what programming language is and its types.

ASSUMPTION: it is assumed that the students do not know what programming Language is all about.

ANTICIPATED PROBLEMS: The student doesn’t know what Computer programming language is all about

POSSIBLE SOLUTION: The teacher takes the student through the lesson and explains the term computer programming language.

TEACHING AIDS: marker, chalk, computer programming software (python).

Definition of Terms

Language is a system of communication by written or spoken word which is used by the people of a particular country or area.

Computer language is a system of instructions and commands for operating a computer. It is a language that the computer understands and executes.

A program is a series of instructions which enable the computer to carry out some laid down procedures to accomplish a given task or solve a problem.

Programming is the act of giving the computer a set of instructions or codes to carry out, or perform a specific task.

Programming can also be said to be the process of taking the step in a procedure and putting such in special languages (coding), which is the computer can understand.

A computer programming language is a large number of steps required to carry out a procedure, for example, to compute student examination scores.

Types of Computer Programming Languages

There are two types of computer languages:

Low-Level Language: Unlike human beings, the computer understands codes of digital binary numbers. These binary digits are made up of zeros (0) and ones (1), for example,1100011, 10000111, 101001101. These digits are called low level language and it is the language the computer understands since the CPU operates by responding to electrical signals. There are two types of low-level languages. They are:

1. Machine language and
2. Assembly languages

High-Level computer programming Language:

High level languages are human understandable languages. They allow programmers to write programs that are not dependent on the design of the CPU. High level languages are human languages and are used to solve problems.

The advantage of high-level languages over low level languages is that they are easier to read, easier to write and easier to use. However, programs written in high level languages must be translated into a language the computer understands. i.e. machine language by a translator. Examples of high-level languages are:

1. Fortran
2. COBOL
3. Logo
4. Pascal
5. Algo
6. Dbase
7. C
8. C+
9. C++
10. Basic
11. Java

EVALUATION:

1. Define the following;

(a) Programming (b) Programming Language (c) High level Language

• Write short note on Low-Level Language.
