What are the in-universe and out-of-universe meanings behind the names droids are given?

The out-of-universe origin of R2-D2 ("Reel 2 - Dialogue 2") is widely known, but what about in-universe?

There a question about the out-of-universe meaning of C-3PO as @Richard points out, but what about in-universe?

My question is different because I'm looking for a long list of in and out-of-universe info on the many droids of Star Wars.

  • IG-88
  • TC-14
  • C1-1OP
  • 4-LOM
  • R4
  • 8T-88


What do they all stand for?

  • They aren't names, they're model numbers. The letters indicate they type, the numbers seem to indicate the series. Like a T-1000 or an HK-1 – Valorum Dec 13 '15 at 11:56
  • It looks like the question @Richard linked is the out of universe version, so this question may do better focusing on the in universe reason. – AncientSwordRage Dec 13 '15 at 11:59
  • There's also 0B1KN0B. – Mr Lister Dec 13 '15 at 12:19

    "List away, people!". Dupe or not, what you're asking for is too broad. – phantom42 Dec 13 '15 at 15:12

In Star Wars Insider #58 (Page 97), it is noted that the in-universe robot names are fragments (shorter versions) of longer serial numbers.
