Games Programming with Java and Java 3D

number of temporary objects created during execution. Knowing which version of Java you are using is important, especially when executing applets. Many browsers, such as Netscape 6 and Microsoft Internet Explorer 6 default to a JVM at version 1.1 unless the user configures things differently. The speed-up in Java is mostly due to improvements in compiler design. The Hotspot technology introduced in J2SE 1.3 enables the run-time system to identify crucial areas of code that are utilised many times, and these are aggressively compiled. Hotspot technology is relatively new, and it's quite likely that future versions of Java 6 Games Programming with Java and Java 3D will find further speed-ups. The Hotspot technology has the unfortunate side-effect that program execution is often slow at the beginning until the code has been analyzed and compiled.

Valime vahel juhuslikult, ehk: teeme vahel vigu  The five types of information that are the only types the computer commonly manipulates:  Visual (pictures)   Numeric (numbers)  Character (text)  Audio (sound)  Instructions (programs) Modern computers work in a system of numbers called binary numbers  Binary numbers:  Similar to familiar decimal system.  Uses only two symbols: 0 and 1.  The choice of using binary numbers is dictated by cost and reliability.  Binary circuits:  Electronic circuits are cheapest and most reliable if they only assume two states or conditions.

Motherboard - the principle printed circuit board assembly in a computer; includes core logic (chipset), interface sockets and/or slots, and input/output (I/O) ports. Printed circuit board (PCB) - a thin, laminated sheet composed of a series of epoxy resin and copper layers and etched electronic circuits (signal, ground and power) Chipset (or core logic) - two or more integrated circuits which control the interfaces between the system processor, RAM, I/O devises, and adapter cards. Processor slot/socket - the slot or socket used to mount the system processor on the motherboard AGP - Accelerated Graphics Port - a high speed interface for video cards; runs at 1X (66MHz), 2X (133MHz), or 4X (266MHz). PCI - Peripheral Component Interconnect - a high speed interface for video cards, sound cards, network interface cards, and modems; runs at 33MHz.
