Points to be discuss in this presentation

1. What is Language?
2. What is program?
3. What is text editor?
4. What is Operating system?
5. What is storage Device?

1. What is Language & Programming language?

Language: 

Language is mode of communication that is used to share information between two or more than two entities.

Programming language: 

For communicating with machines we need specific language which machine  can understand and execute the operation, that language is called programming language.

Examples of languages are C, C++, Java, Golang, Python, Php, .net, C# and so on.

2. What is Program?

Set of instructions is called Program. 

Or, The sequence of inspection in the programming language which operating system can understand and perform specific task written in the code. 

To save the program we need to follow some rules like name of the program followed extension of the language.

For example program.c, program.cpp, program.java and so on. 

All languages have there own extensions. 

3. What is text-editor?

Editors are used to create documents or allow us to add , update and replace the content of the document.

Normal editor like MS office store intrestions along with text. I.e. if we add text with bold characters like “Hello” so it will add hello text with property as font type bold.

Alike Plane text editor, They only store data written inside it without any other instructions. E.g. Notepad, Vim, Vi and so on.

4. What is OS (Operating System) ?

Operating system is a system software.

 OS is a bridge between code instructions and hardware. That means whatever you will write as code or program that need environment to run or interact with hardware to execute that environment is called operating system.

Some examples of OS are Windows, Linux, Unix, MacOs and so on.

5. What is Storage Device?

Storage devices are something which is used to store data. 

There are 2 types of Storage devices in computer are as follows:

1. Primary Storage

E.g. RAM (Random Access Memory), ROM (Read Only Memory).

1. Secondary Storage

E.g Floppy Disk,  CD, DVD, Tape, Hard Disk, USB Drive and so on.

Anything we stores in the system is stored in the secondary device. But when we run that file or program then it run in the RAM.

That means to run any application, that application should be in active state so OS automatically load that application or file into RAM for executions. 

Data Initially load in RAM, but When it comes to store it we need secondary storage.

For how long RAM stores the data?

Once you execute any application it stores in RAM, Data will be in RAM until that program is running and data belongs to that application. 

Once application close data vanishes that is the reason we called RAM as volatile memory or temporary storage.
