Which Version of PlayStation 3 Should you Buy?

With the long awaited release of the Playstation 3, its sure to have gamers all around scrambling to purchase this new system. There are two different consoles and prices of the PlayStation 3: the 20GB version and the 60GB version. Each console will have something different to offer and different price tags as well.

The first version of the Playstation 3 is the 20GB version and will retail at $499.99. The next Playstation 3 is the 60GB version and will retail at $599.99.

The new console design has a more sleek and simple design and weighs less than the other console systems. The first version of the model is only going to be offered in black, but some indications state in the future other colors like; white and silver will be available.

On thing that didnt change in the new video system is the ability to sit horizontally or vertically. With an AV rack it can be placed in both positions, otherwise a horizontal position would be preferred to the fact of its curved console shape.

The traditional controllers have maintained the same image and functions through out the years. This is a warm welcome for the experienced playstation gamers. The one thing that has changed on the controller for the better is the enlargement of the L2 and R2 should buttons. An enlarged titling angle of the joystick will ensure better manipulation and wider range of motion. The force feedback vibration has been done away with, fearing the vibration might interfere with certain games that use the motion sensor.

The controller will be wireless comparable to the xbox 360 controller. The wireless controller will operate with a Bluetooth 2.0 EDR that can transmit data at the rate of up to 3.0Mbps.

The Playstation portable will be able to connect to the new console. The PSP can function as a remote control or as an extra controller for the Playstation 3.

The games will use a hard drive to save game and load times will be around two to three seconds.

The 60GB Playstation 3 system will offer a number of features such as four usb ports, compact flash and CD readers, Blu-ray optical disc drive, and memory stick.

The 20GB Playstation 3 will not have some of these features, which is why it costs nearly a hundred dollars less. You will have to decide for yourself which system is right for your needs.

New to Playstation is the Blu-ray disc drive. This disc can hold up to 54GB and can play games and movie discs. With the Blu-ray disc drive you can play high definition DVDs without having to purchase a separate Blu-ray dvd player.

Cisco CCNP Certification / BSCI Exam Tutorial: Comparing IRDP And HSRP

To pass the BSCI exam, you need to know the difference between IRDP and HSRP. While they have the same basic function, the operation and configuration of each are totally different.

The aim of both is to allow hosts to quickly discover a standby router when the primary router fails. IRDP is commonly used by Windows DHCP clients and several Unix variations, but you do see it in Cisco routers as well. IRDP is defined in RFC 1256.

IRDP routers will multicast Hello messages that host devices hear. If a host hears from more than one IRDP router, it will choose one as its primary and will start using the other router if the primary it's chosen goes down.

HSRP is a Cisco-proprietary protocol that is designed for quick cutover to a secondary router if the primary fails, but the host devices don't "see" either the primary or secondary router. The hosts use a virtual router as their default gateway. This virtual router has its own IP and mac address! All the while, the router chosen as the primary is actually the one doing the routing. If the primary router goes down, the secondary router quickly takes over with no major interruption to network services.

The HSRP routers communicate by multicasting updates to 224.0.0.2, and its through these hellos that the HSRP routers decide which router is primary and which is secondary. HSRP is defined in RFC 2281.

The configuration of each of these will be covered in a future tutorial. In the meantime, I urge you to read the RFCs mentioned in this article, and visit www.cisco.com/univercd to read about the configurations and options available for both of these vital protocols.
