Do inlinks work efficiently like backlinks ? Yes Inlinks and Backlinks Both are same. For Internal link you have to optimize it properly and for external link you have to build links for your site through quality and high PR links
it's could be said that : inlink = part of SEO on page backlink = part of SEO off page both are important in basic optimization

External links from relevant websites will improve the PR of the website. Also internal navigation of the website will improve the visibility of the website on main search engines.
The backlinks to your site holds more importance as compared to the inlinks of your site. Although Google does give importance to inlinks of your site and no doubt, it should be good as well like the anchor text must be keyword rich wherever possible, the backlinks are more important as it is seen as many other domains linking to you making your site an authority site for some particular keywords in some particular niche.
