What is professional networking and its impact on career advancement?

Thanks for invitation,

Professional Network is a type of social network service or platform that is focusing on interactions and relationships mainly of a business nature rather than including personals, non business interactions, like the famous " LinkedIn" platform. 

A professional network service is used by business individuals to establish and maintain professional contacts and a way to either find work or get ahead in career as well as gain resources, exchange some professional opinions or updated professional knowledge and opportunities for networking.

Thank you for invitation. I am looking forward to more answer.

Thanks 

I prefer to wait for more answers from colleagues
