G A M I N G C O N S O L E S
A gaming console is a system that is exclusively dedicated for gaming. It has been optimized for game playing as that is its core function. One can play games on a PC or even a cellphone but these are not systems dedicated for gaming, so they cannot be termed gaming consoles.
VIDEO GAME CONSOLES
The core components that all video game consoles have in common are
Ø User control interface
Ø CPU
Ø RAM
Ø Software kernel
Ø Storage medium for games
Ø Video output
Ø Audio output
Ø Power supply
The user control interface allows the player to interact with the video game. Without it, a video game would be a passive medium, like cable TV. Early game systems used paddles or joysticks, but most systems today use sophisticated game controllers with a variety of buttons and special features.
The CPU is the heart of the video game console. It is a microprocessor that powers the game system. Microprocessors are required for the operation of any computational device. On a game console, the CPU coordinates the functions of the various hardware and software units.
The software kernel is the console's operating system. It provides the interface between the various pieces of hardware, allowing the video game programmers to write code using common software libraries and tools.
The two most common storage technologies used for video games today are CD and ROM-based cartridges. Current systems also offer some type of solid-state memory cards for storing saved games and personal information. Flash memory cards can be used to store personal information and game progress. Newer systems like the Microsoft XBox and the Sony PlayStation 2 have DVD drives.
All game consoles provide a video signal that is compatible with the television system. Depending on the country or region, this may be NTSC or PAL/SECAM. NTSC is commonly found throughout America while PAL/SECAM is the dominant TV system in Asia and Europe. Most consoles have a dedicated graphics processor that provides specialised mapping, texturing and geometric functions, in addition to controlling video output.
Another dedicated chip typically handles the audio processing chores and outputs stereo sound or, in some cases, digital surround sound. Modern game consoles have sound processors that have DTS functionality.
Power supply is required in some form or the other by virtually any device today.
Ever since the early days of the Atari 2600, video game systems have always relied on RAM to provide temporary storage of games as they are being played. Without RAM, even the fastest CPU could not provide the necessary speed for an interactive gaming experience.
