Since I have been a corporate trainer, I have seen people from different disciplines struggling while learning to program.
So I though I will brief out what is programming and basic terminologies using in programming.
Consider a scenario,
You are going for your best friend’s marriage and at one corner of the marriage hall, you see your school time crush talking with his/her gang of friends.
Somehow you manage to talk to him/her and get his/her mobile number and store it in your phone.
If you are outside of India this might sound weird. You might think like why would someone hide their crush for 10 to 15 years.
Believe me, for Indians, talking with their crush is still a big deal.
Coming back to programming, now that you are storing your crush’s number in the phone, lets see how this data is manipulated by mobile phone.
To type in the number, you will be using “Contacts”.
“Contacts” in this case is an application/a program that is running in your mobile phone.
For any application to run, it needs a base software which is otherwise called
Operating System (OS).
OS in mobile phones can be Android, IOS, Symbian, Oxygen OS, etc
OS in computers can be Windows, IOS, Linux (Ununtu, Redhat, yocto, etc).
Now that you have entered your your crush’s mobile number through “Contacts”‘s keypad, you will try to add in a name for the contact and then click on “Save”.
These data like : mobile number, name, email address, alternate number, etc will be handled as
Literal meaning of ‘Variable’ is “something which tends to change”.
variable in a program can store
data and that
data can be changed by the application at any point of time.
In the above scenario, the phone number of the crush and his/her name can be stored in
variables by the application.
The visuals you see as part of the “Contacts” application is identified as
Graphical User Interface (GUI).
Once the “save” operation is successful, you will be able to access that contact as many time as possible.
To retain the data of a variable for a longer duration, the data will be stored permanently in
The communication between
GUI will be through a
set of functions which can be cumulatively called as
Considering all the parts explain above, I would like to summarize
“Programming is creating application/software to ease out daily tasks in a more efficient way”
“Program, in most cases, gets input from user, processes it and provides an output”
Add in you comments in case of any queries.
