Node vs. entity in drupal

Please find below given clear explanation…..

  • To me, the concept of “node” is fairly clear: It is an “instantiation” of a content-type. When you add content, you choose the type, e.g. “Article”, and the content that you add (e.g. the article text, title, images, etc.) is stored as one unit in the database, and is also often assigned its own URL path. A node is then retrieved, upon user request (i.e. the appropriate HTTP GET), by the node module and passed on to the template which places in on its appropriate place in the layout and generates and returns the webpage (the actual final markup that is served to the browser) by adding in other components of the page (e.g. menus, blocks, etc.). What I find a bit fuzzy however is the concept of entity. A user is an entity, so is a node? How about a role, or a block? How about a comment or a menu? Are those entities too?I can’t yet quite see its place in the overall scheme.
  • To me, “entity” is just a fancy synonym for “thingie”, which is about as vague (or general/abstract) as you could get. Indeed, if knew what is NOT an entity, it might become clearer.

Main difference between drupal and wordpress

  1. Drupal wins this round. WordPress’ many plugins can have vulnerabilities and be easily hacked, particularly if the website owner doesn’t update to the latest version or the plugin gets old. Or simply, hackers target WordPress because it is so popular. However, there is a paradox solution: install third-party plugins that increase your security.
  2. One big difference between the two is how they handle mobile sites. Many of Drupal’s mobile themes run better off a subdomain, which creates two separate URLs to index in search engines i.e. http://www.yourdomain.com and http://www.m.yourdomain.com. WordPress doesn’t have this issue as most of its themes are mobile responsive.
  3. Search Engine Optimization isn’t platform specific but there are a few tricks that make one better than the other. Both have SEO built into them. It has been said that Drupal was built specifically to be search engine friendly but WordPress has a multitude of plugins that can enhance this.  Drupal’s pages tend to load faster due to its default caching features, and search engines put a preference on faster websites.Drupal is also able to handle larger amounts of content. A large volume of useful content is important for SEO.
