Visamy - look's like you have done now on RG. If it counts as a conference proceeding - then it should have a DOI number that will widen the publication even more i.e. your ORCID account.

Thank you so much for your help sir

A poster is a type of publication, just like a conference paper is another similar type. A poster does have copyright protection.

Of course, different fields and institutions place different value on the various kinds of publications.
