Why Server side programming and its meaning what... And what client side programming.. please explain me??

Answer 1

ok, you typing some words and post this poster, what you seeing and what you doing is client side.
when you click the post button , the data transfer to server, and server starts receiving your data and do something, it's server side.
the server transfer the data what servers done to your browser, it's server side, and browser get the data then you can see the post, it's client side.

Answer 2

If you open text editor , write html tags with css and some javascript and save all this on your pc desktop as "test.html" file , then open this file by your browser , gess what? it will run! you will see all the html tags styled by the css properties and also the java script will work.

All this was doen at your side no server was involved for running your code just the browsers, client side programming is what your browser can understand and run and its usualy done by html,css and javascript.

usualy in real world things doesn't work like that , you can see this page now because you typed in your browser "www.sololearn.com" , the sololearn files are not exist on your local pc they are some where on sololearn server, this server host all sololearn website files,pictuers ect.., your browser just call them from there, and your browser run all the html ,css, and javascript that sololearn developers developed .

but what about all the data how you can see all the other users profiles,pictuers,answers ect..? how you even can see this answer ? is there some developer who take it and wrote it to html tags ? sure not !

The answer is server side programing , server side programing is code that run at the server you cant see the code , it can do complix things like save this answer to database , or read other users answers , or bring other user profile data , or even more complex functunality , and all this data sent back to your browser as html tags.
server side programing is done by few programing languages , such as java ,.Net c# , php ect..
