A user -installable microprocessor from Intel for the 486 microprocessor. Many PCs 486-based PCs are built with an OverDrive socket, which allows the owner to upgrade to a faster microprocessor simply by inserting an OverDrive chip.
- obfuscated URL
Also called a hyperlink trick, an obfuscated URL is a type of attack where the real URL that a user is directed to is obfuscated – or concealed – to encourage the user to click-through to the spoof Web site. For example, the attacker may use a cleverly misspelled domain name (e.g. PayPals.com instead of […]
Generally, any item that can be individually selected and manipulated. This can include shapes and pictures that appear on a display screen as well as less tangible software entities. In object-oriented programming, for example, an object is a self-contained entity that consists of both data and procedures to manipulate the data.
- object code
)The code produced by a compiler. Programmers write programs in a form called source code. The source code consists of instructions in a particular language, like C or FORTRAN. Computers, however, can only execute instructions written in a low-level language called machine language. To get from source code to machine language, the programs must be […]
- object oriented
A popular buzzword that can mean different things depending on how it is being used. Object-oriented programming (OOP) refers to a special type of programming that combines data structures with functions to create re-usable objects (see under object-oriented programming). Object-oriented graphics is the same as vector graphics. Otherwise, the term object-oriented is generally used to […]
- object-oriented graphics
The representation of graphical objects, such as lines, arcs, circles, and rectangles, with mathematical formulas. This method of describing objects enables the system to manipulate the objects more freely. In an object-oriented system, for example, you can overlap objects but still access them individually, which is difficult in a bit-mapped system. Also, object-oriented images profit […]
