What is Programming?

Programming is the process of creating instructions that tell a computer how to perform specific tasks.

A set of instructions written in a programming language is called a program. Computers follow these instructions step by step to solve problems, process data, or perform actions.

Simply put, programming is the way humans communicate with computers.

For example:

  • A calculator application performs mathematical operations.
  • A website displays information to visitors.
  • A banking system manages customer transactions.
  • A mobile app provides services on smartphones.

All of these systems work because programmers write instructions that computers can understand and execute.

What is a Program?

A program is a collection of instructions designed to perform a specific task.

Examples of programs include:

  • Microsoft Word
  • Web browsers
  • Mobile applications
  • Video games
  • Banking software
