I undestand what is a protocol: it is a set of rules agreed upon by 2 or more computers that they will follow while communicating with each other.
Now, my query is: who creates a particular protocol and does he specify somewhere that only these applications can use that protocol while creating the protocol?
If not, then what is the need to create different protocols?

Organizations like IEEE, ISO and ITU develop, create, standardize and maintain the communication protocols. Many different highly skilled engineers are part of these organizations from all over the world.

Thanks Romeo for the reply. Does these organizations specify somewhere that only some specific applications can use that protocol while creating the protocol? If not, then what is the need to create different protocols?

No, it is not specified which applications can use the protocol. Its up to to the programmer, designer or the engineer how he/she uses it.

Different protocols are created to provide different functionality. For example, HTTP protocol describes how a web server and a client computer have to communicate. FTP protocol is specialized in handling files over a network.

Some protocols are created for a special need as a subset of other protocols (they make use of existing protocols). One example is SOAP protocol makes use of HTTP to transfer specially structured information.
