what is program in computer

computer program


In today's class we take our first lesson in computer programming. We have by now acquainted ourselves with the basics of computers, their components and their uses.


In short, a computer is a machine that accepts an accumulation of raw data and a compliance set of instructions, manipulates the raw data based on instructions and obtains the final result in the form of information that is meaningful to us.


As is clear, in order to be able to get a computer to perform its tasks, we must communicate with it by providing instructions on what we want it to do. This brings us to our first basic principle - what is a computer program? Or what is programming?


A program: is a set of instructions in a specific order for the computer to perform a specific task in order to give the desired output or result.


Similarly, computer programming refers to the science of writing programs for computers to perform tasks for us and produce desired results in a human intelligible form.


Communication as we know, is a two way process where two parties are involved and they must understand each other. If not, it leads to what we know as communication gap.


We communicate with computers when we issue instructions (programs) and data to be processed as inputs. The computer communicates with us when it gives us the desired result in the form of output. Like all forms of communication, we need a language to be able to communicate our information and understand what the other party says. This brings us to our next area of ​​study - programming languages, which we will learn in our next class.
