  • incremental backup — (operating system)   A kind of backup that copies all files which have changed since the date of the previous backup. The first backup of a file system should include all files - a "full backup". Call this level 0. The next backup could also be a full level 0 backup but it is usually much quicker to do a level 1 backup which will include only those files which have changed since the level 0 backup. Together the level 0 and level 1 backups will include the latest version of every file. Level 1 backups can be made until, say, the backup tape is nearly full, after which we can switch to level 2. Each level includes those files which have changed since the last backup at a lower level. The more levels you use, the longer it will take to restore the latest version of a file (or all files) if you don't know when it was last modified. Compare differential backup.

  • multicast backbone — (MBONE) A virtual network on top of the Internet which supports routing of IP multicast packets, intended for multimedia transmission. MBONE gives public access desktop video communications. The quality is poor with only 3-5 frames per second instead of the 30 frames per second of commercial television. Its advantage is that it avoids all telecommunications costs normally associated with teleconferencing. An interesting innovation is the use of MBONE for audio communications and an electronic "whiteboard" where the computer screen becomes a shared workspace where two physically remote parties can draw on and edit shared documents in real-time.

Abbreviation: N.A.
  • numerical identity — the relation that holds between two relata when they are the selfsame entity, that is, when the terms designating them have the same reference

  • objective modula-2 — (language)   (Or "ObjM2") An extension to Modula-2 for Cocoa and GNUstep software development. Objective Modula-2 follows the Objective-C object model and retains the bracketed Smalltalk message passing syntax used in Objective-C. Classes written in ObjM2 can be used within ObjC and vice versa. ObjM2 also retains Modula-2's data encapsulation features, namely nested modules with explicit import and export lists. Due to the strict type checking in Modula-2, ObjM2 can be considered a much safer programming language than is ObjC, yet losing none of the capabilities of ObjC.
