PROGRAMMING HISTORY

In the previous blog we have learnt that  why the concept of computers have emerged . In this we are going to learn how and when the concept of programming has been came.

People always in search for faster calculations so the invented Abacus.

Generally Abacus is a frame holding rows of beads suspended on metal rods. Each row represents a power of ten in calculations. In this way they did faster calculations.

You can Know more about Abacus by navigating to this link->Abacus 

Later many of the devices have been came for faster calculation like pascals calculator , Napiers bones etc ...

but all these are not easy to learn and physical dependent.So all these cant reached  user requirement. Actual concept of programming was came when Charles babbage invented Difference Engine in 1822.

 In general if we consider when any ask you to prepare for a coffee you need to have a knowledge about preparation of coffee.What if you don't have any of the knowledge to prepare coffee you cant do it. If any one instructs you step by step process  to prepare then you are able to do it . This step by step process is called Algorithm and the steps are called Instructions.Likewise computers also need a way to instruct them so it can work according to the instructions .These instructions are given by language called programming language.

 Babbage's Difference Engine could only be made to execute tasks by changing the gears which executed the calculations. Thus, earliest form of a computer language was physical motion. But later physical motion was replaced by  electrical signal when us government introduced ENIAC in 1942.

Computer basics

UNDERSTANDING COMPUTER AND PROGRAMMING BASICS

To fully understand the programming language, one must understand the reasons behind its creation.

The main reason behind its creations is  for computation purpose.
As we go back to history people used to calculate  by counting their fingers and made calculations, but it was limited as we all have only ten fingers.So people as usual they are in search of  new ways to calculate.
As a result of this they have found a method called counting with stones. which means  placing the stones on the ground  and they used to count. But it also has a limited scope.


In this way people always in search of a easy ways to calculate .The result  was Abacus to present age Computers.

Programming basics

Inorder to learn programming we should know why to learn it and what are the uses by   learning it .

In this page I mainly concentrate on the basics of the programming languages. so you are able to develop your programming skills.
