Classwork Series and Exercises {ICT- JSS2}: Computer Programming Language



Computer Programming Language

Computer programming language can be defined as an act of writing a program which a computer can execute to produce the expected or desired result (output).

Programming language can now be defined as a sets of rules given to the computer to perform a given task or operation.

There are basically three types of programming language and they are discussed in details as follows:

1.  Machine language: This can be regarded as the original computer language. It is made up of instruction codes written or documented in binary form (0s and 1s) and because it is documented in long strings of binary digits (0s and 1s), it is not easy to understand thereby lead to an advent of Low-level and High-level language.

2.  Low level language: This is also known as ASSEMBLY LANGUAGE. It is a program written using symbols to denote codes. Its codes are more meaningful and easy to learn. For this language to be in a computer readable form, it has to be translated by a software or translator called An Assembler.  

3.  High level language: These programming languages are developed with the purpose of contributing to the solutions of business or scientific problems and they allow statements to be made closer to natural human language such as English. It is not sensitive to machine or computer unless it is translated by translators called Interpreter or Compiler.

Examples of High level languages include: BASIC, FORTRAN, COBOL, VB, JAVA etc.

BASIC – Beginners All-purpose Symbolic Instruction Code

FORTRAN – Formula Translator

COBOL – Common Business Oriented Language

VB – Visual BASIC

JAVA – JAVA (Developed by Sun Microsystems and named after an island called JAVA)

Benefits of High Level Language

I)     Debugging of errors is made easy

II)    They are easy to comprehend because they are closer to human language

III)   They can be transferable from one computer to the other

IV)  It provides the students with an ability to interact directly with computer

Disadvantages of High level language

I)     It is less flexible in structure

II)    Greater storage capacities and more running time is needed compared to the low level and machine language
