We know the difference between paid and free, Free software for whom we did not pay and paid software is whom we give money. There is so many paid software is present in the market, some gives one month free trial, some give us few options for free and if you want more options they you pay for that. So, it is clear what is free or what is paid. So many peoples thinks free software is open source software and open source software is open, they thinks opensource software and free software is same.
So, basically there is very big difference between open source software and free software. Many times you heard Android is open source software, what is meant by this. Opensource software means there source is open, the source code by which that software is developed and there modules is open for all developers. It different developers change that software according to him, they tweaks some thing in that software and represent him. Because android is open source software that's why we see android in different forms. All manufacturer change the android skin according to him, some time they add some thing and some time they reduce some things. That's why when we use different android we feels some thing different.
I tell you one important thing, all open source software is not always free and all free software are not open source software. Android id free for all manufacturer and all user but google charge some licencing fees to manufacturer if they want to use google services. From that google earns, if google gives there all services in free of cost then just think how google can earn.
There is so many software is present in the market like this. If you want to buy a software then you have so many options, like if we talk about photo shop then it is a paid software and a similar software called gimp. They do all most exect same thing, but they are free open source software. Like that if we talk about video editing then there is a software called adobe premiere pro they are paid software, there is a software called hitfilm is also present in the market and they are free. Its totally upon you which software you can use paid software of free software.
In open source software you get some benefits like in you software there is a bug, there is a problem and if you enhance there features then there is a developer team who work on that which basically means you did'nt want to depend on software wender. In open source software random developers are working and enhancing that software. So it is the best thing about opensource software.
I explain you all thing about open source. Now what is close source software, close source software is like apple os, windows os. Close source software is exactly opposite of open source software. In close source software no one can make change in that software. If we talk about free software then it means all services is given free by developer they did not charge any thing for there services. But free software is earns from ads. In many free software there is so many ads is placed.
