I am Rafiqul Islam.I am very much interested to be a programmer,but i don’t know exactly from where i will start.i want to start very basic.Please give me suggestion.

Well Rafiqul, what do you want to do?

There’s front-end programming which are things like web design, but there’s backend which is things that are a bit heavier, like SQL, Server work, etc.

Most people tend to start with HTML & CSS, then go to JavaScript, then work on whatever appeals the most to them from there.

Some Wikipedia pages on what @rhyscrypto said:
