Everything is made from smaller components. Understand each of those components better and you'll understand the entire system better. Sometimes, you can use end-errors to tell which component has the issue. For instance, if a web site gives a 502 error, the problem is likely with the load balancer or lower network stack on the web server. 404 would often be a file system level issue on the web server. 500 is frequently a network issue between web server and database server. 400 is a problem with the site presentation code, or maybe database malforming addresses. |

This. No matter how specialised you are (or want to be) always strive to have at least a basic understanding of the full stack and everything else that your work touches through a couple of levels of indirection (including the wetware such as, in commercial contexts, having a good understanding of your client's business even if you aren't even close to being client-facing) because it will help you produce much more useful/optimal output and can be a lot more helpful when your colleagues/compatriots/partners/what-ever his a technical problem. Heck, at the logical extreme a little cross discipline understanding could even lead you to discovering a better method of doing X that strips out the need for Y altogether, revolutionising how we do Z.
Of course don't go overboard unless you are truly a genius... Trying to keep up with everything in detail is a sure-fire route to mental burn-out!
