NOTE

PROGRAMMING LANGUAGES

A computer program is a set of instructions that directs a computer to perform tasks.

A programming language is a set of words, symbols and codes that enables a programmer to communicate instructions to a computer.

A programmer is someone who writes and modifies computer programs.

Programming is the act of writing instructions for computer to perform a specific task.

Categories of Programming Languages

There are a number of programming languages existing today. Each language has its own rule for-writing the instructions. Programming languages are designed for specific purposes, such as scientific applications, business solutions or web page development.

Programmers must decide which programming languages and tools to use when they write programs.

Types of Programming Languages

1. 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
