GG45

The GG45 (where GG stands for GigaGate, and 45 is to remind the backward compatibility with the 8P8C modular connector - often colloquially called RJ45) is a connector for high-speed Category 7 cable (generally known as Cat 7) LAN cabling developed by Nexans.

Passphrase

If backward compatibility with Microsoft LAN Manager is not needed, in versions of Windows NT (including Windows 2000, Windows XP and later), a passphrase can be used as a substitute for a Windows password.

SuperDrive

This was made possible as the SuperDrive now utilitized the same MFM (Modified Frequency Modulation) encoding scheme used by the IBM PC, yet still retained backward compatibility with Apple's variable-speed zoned CAV scheme and Group Code Recording encoding format, so it could continue to read Macintosh MFS, HFS and Apple II ProDOS formats on 400/800 KB disks.
