A Computer Program:

When we say that we have a program, it means that we know about a complete set of activities  to be performed in a particular order to solve some problem.The purpose of these activities is to solve a given problem. So the definition of a Computer Program is,  "A  computer program is a precise sequence of steps to solve a particular problem."
At its most basic level, programming  a computer simply means  to tell a computer what to do. The process of telling a computer what to do needs special training because computers do not understand our language. So to talk with a computer we need to learn that language which a computer could understand.
So, we can say programming is a way of sending instructions to the computer. To create these instructions, computer programmers use  programming languages to create source codes then they convert the source code into machine language  for the computer.
