Explanation:

Convention on Cybercrime, also known as the Budapest Convention on Cybercrime or the Budapest Convention is the first international treaty seeking to address Internet and computer crime (cybercrime) by harmonizing national laws, improving investigative techniques, and increasing cooperation among nations.  

• The convention is the sole legally binding international multilateral treaty on cybercrime. It coordinates cybercrime investigations between nation-states and criminalizes certain cybercrime conduct.
• It serves as a guideline for any country developing comprehensive national legislation against Cybercrime and as a framework for international cooperation between State Parties to this treaty. 
• The Budapest Convention is supplemented by a Protocol on Xenophobia and Racism committed through computer systems.
• This Convention has eagerly called for Indian participation since its formation in 2001, but India has not acceded to the Budapest Convention.
