- 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.

- optical disc drive — optical disk drive
- optical disk drive — (hardware) (Or "optical disc drive", "optical storage") A generic term for any device that reads and/or writes optical media, i.e. compact discs, DVDs and/or Blu-ray discs or future media that uses light (from a small laser) to read data off a removable, rotating disk. At least one such drive is commonly installed in most personal computers to allow them to play and/or record audio and video media and load and store data such as program installers. The floppy disk has been replaced by optical media due to its vastly greater capacity, e.g. 50,000 megabytes for a dual-layer blu-ray disc compared with 1.5 megabytes for a floppy (over 30,000 times as much).

- partial evaluation — (compiler, algorithm) (Or "specialisation") An optimisation technique where the compiler evaluates some subexpressions at compile-time. For example, Partial evaluation might change the termination properties of the program if, for example, the expression (x * 0) was reduced to 0 it would terminate even if x (and thus x * 0) did not. It may be necessary to reorder an expression to partially evaluate it, e.g. f x y = (x + y) + 1 g z = f 3 z If we rewrite f: f x y = (x + 1) + y then the expression x+1 becomes a constant for the function g and we can say g z = f 3 z = (3 + 1) + z = 4 + z Partial evaluation of built-in functions applied to constant arguments is known as constant folding. See also full laziness.
