| Object Linking and Embedding(OLE) | A proprietary software system from Microsoftthat allows applications to transfer and share information. When a change ismade to a shared object in the original application, any document that containsthat object is updated automatically to reflect the changes. |
| object-oriented | While the specifics are well beyond the scope of this document, the term "object-oriented" applies to a philosophy of software creation. Often this philosophy is referred to as object-oriented design (sometimes abbreviated as OOD), and programs written with it in mind are referred to as object-oriented programs (often abbreviated OOP). Programming languages designed to help facilitate it are called object-oriented languages (sometimes abbreviated as OOL) and databases built with it in mind are called object-oriented databases (sometimes abbreviated as OODB or less fortunately OOD). The general notion is that an object-oriented approach to creating software starts with modeling the real-world problems trying to be solved in familiar real-world ways, and carries the analogy all the way down to structure of the program. This is of course a great over-simplification. Numerous object-oriented programming languages exist including: Java, C++, Modula-2, Newton Script, and ADA. |
| Object-Oriented Graphics | Graphic designs that are handledby the computer as mathematically-described shapes, rather than as collectionsof pixels.Often referred to as drawing as opposed to painting. |

| Open | To display the contents of a file inan application or to start an application. |
| Open Architecture | A type of IBM PCand compatible architecturethat allows third party manufacturers to produce additional interior add-ons(usually circuit boards), and to allow users to easily install these add-ons. |
| open source | Open source software goes one step beyond freeware. Not only does it provide the software for free, it provides the original source code used to create the software. Thus, curious users can poke around with it to see how it works, and advanced users can modify it to make it work better for them. By its nature, open souce software is pretty well immune to all types of computer virus. |
| Open Transport | The new networking section of theHREF="#MACINTOSH">Macintosh systemsoftware. Available in System 7.5.2 for PCIMacintosh models. This package integrates control of Ethernetand Localtalk,and the implementation of AppleTalkand TCP/IP.System 7.5.3 will contain Open Transport for all Macintosh models. |
| OpenBSD | A free variant of Berkeley UNIX available for Alpha, x86, 68xx, PA-RISC, SPARC, and PowerPC based machines. Its emphasis is on security. |
| OpenDoc | A standard for applications and documents createdby a consortium of Apple,IBM,and Novell. OpenDoc is intended to provide more cross platform and crossapplication integration, by splitting up the components of documents (text,sound, graphics, etc.) and providing separate access to each component throughmodular software. |
| OpenGL | A low-level 3D graphics library with an emphasis on speed developed by SGI. |
| Operating System | The systemsoftware. There are a number of different operating systems, which havedifferent design philosophies, provide different facilities, and have differentlooks and feels.

They are extremely inexpensive but are typically incapable of running any special purpose applications and are thus of limited use. |
