What is Case Sensitive?

Before knowing case sensitivity lets firstly know what is case.  ABCDEFGH........... these alphabets are written in Upper Case( Capital letters are termed as Upper case). Similar to those abcdef......... are Lower Case alphabets (small letters are known as lower case). Now any language which is sensitive about cases (upper case & lower case) are known as case sensitive language.

If a language is case sensitive then, for that language BOOKS & books  are two different things.

"CURRENTLY YOU ARE ON TECHNICALVINAYAK.BLOGSPOT.COM" (This line is written in upper case)

"currently you are on technicalvinayak.blogspot.com" (This line is written in lower case)

"Currently You ARe ON technicalVINayak.blogspot.com" (This line is niether in upper case nor in lower case but a case sensitive language treat it as a different thing. And for html or any other non case sensitive language all three are same)

How case sensitivity matters

Lets understand it with an example

<html>

<body>

<p> This is an example </p>

</body>

</html>

 In the above example we have used html tag, body tag, and paragraph tag. We have written all tags in lower case but we can write the same code is written in the upper case and there will be no change in the output. 

<HTML>

<BODY>

<P> This is an example </P>

</BODY>

</HTML> 

I hope case sensitivity is clear  now.
