Question about pings and backlinks

I am just new to the domains world so i was just asking myself what pinging your website and backlinks are for and how can i make them for my own website. Also is there any basic thing i need to know to get more traffic on my website? Thanks for the help!

To walk, you must crawl. To crawl, you must first learn to use the search option in the forum. If all else fails, hit a search engine. Good luck
