applications episode 3

what is the application born ?

the application born is the period that the main idea of the application appears for the first time to the programmer or the developer of the application

the actual birth is when the application is fully coded and all of it’s parts are complete , so the birth date of any application is the date that the application is totally released to be used by any one.

what is the application BUG ?

the application BUG is a type of disability that the application was born with , so it can be an error in the code of the application , or it’s a case when the developer didn’t include all the application work conditions .

for Example : i mad an application to sum (no1 + no2) , so i learned the application to do summations , later the user of the application ask the application to do this quotation(no1 – no2)

the application response will be an error . this is called a bug where the developer forgot to supply the application with all running conditions / circumstances

how could applications work?

• applications need a place to work in.
• applications need a specific tasks to do or to execute.

the place where all applications could work ,  is  computer hardware , as soon as computer hardware is  manufactured , applications will be loaded on it , and we can call those applications “Main applications “.

those applications were kept in a place called  ROM  “Read Only Memory” ,in this place they will be stayed for along time.

Now , Main applications have a place to work , so what those applications are going to do ?

• Main applications are used to check if every thing is OK and then give an order to the second application to run himself on line .
• the second application is OS ” Operating System” , which we will talk about it later.

What is the application ?

• the application is a computer life form.
• the application is the way that computers can express different actions and share it with both humans & other computers.

• applications are consisting of 3 main parts ( inputs + processing + outputs ).
• the inputs some times are called  (GUI) ->” graphical user interface “.
• the processing is the ideas of the human developers that was kept in the application as rules and orders that must be obeyed , also we called it CODE.
• the outputs are the final result that is shown after processing the inputs.

what are the different types of applications ?

• PC application or computer application
• web application
• mobile application

those are the main three types of any application

who can develop or create applications ?

• any one who knows programming languages can develop anew applications
