A short overview of the history of arcade games and flash games will show that there is a huge connection between these two types of games. Arcade games have a long history and, even though the arcade games were not in the past what we know them to be today, the same concept is the main ingredient for the new ones as well. The arcade games are usually simple, have iconic characters, a certain number of levels with increasing difficulty and they do not require high skills or much learning time. In addition, they do not have deep storylines as most console games have in our days. Today’s PC or console games with the same qualities can be considered arcade games.

Starting from the early 1920’s with the use of old ‘arcade games’ in the amusement parks (such as ball toss games, coin-operated machines or pinball) this whole ‘industry’ has evolved immensely. This passion for arcade games motivated their producers to always search for something better and more entertaining. They have outdone themselves every time something new appeared on the market. From wood made machines and mechanical or electronic scoring readouts to the playing of games online, all games have conquered the hearts of the ageless children. Because people enjoy these arcade games so much they want to play them all the time. This is why they have not even completely left aside the coin-operated arcade games. They resort to them in restaurants, shopping malls, bars or pubs. However, they are only a substitute to the computer versions because playing games online is much better.

When speaking of flash games, we must take into consideration the fact that they are a more complex, more modern, even if their ancestors are definitely arcade games. Flash games take their name from the platform used for their building – ‘Flash’, a program made by Macromedia. This modern interactive platform named ‘Flash’ has three major components: the player, the file format and the authoring tool. The main advantage of this program is that of being very easy to use. Because of this fact, the games built with the help of the platform have more options than others do. For example, a house the player destroys will burn down with different effects. In order to be more convinced of the high importance that this platform has for us when playing a flash game we should know that it is usually necessary to download a free version of Macromedia Flash Player each time one feels like playing free games online. Generally, you can download the latest version of ‘Flash’ from Macromedia. That is if your browser gets errors relating to Flash.

If you simply like to play good games online without knowing the whole technique that stands behind graphics, too many details about the designing of flash games are unnecessary. Flash games are all the games you play at home on your computer and have the ending ‘.exe’ (meaning ‘executable’). As long as they make you enjoy the spare time spent at home, the flash games will be your best friend. A favorite application can turn into a real sport because playing flash games stimulates competition and trains reflexes. Web sites that host these kinds of activities and offer you free games give you the opportunity of joining teams of players and of participating to mass championships online.

Passing the BCMSN exam and getting one step closer to the CCNP certification means learning and noticing details that you were not presented with in your CCNA studies. (Yes, I know – you had more than enough details then, right?) One protocol you’ve got to learn more details about is VTP, which seemed simple enough in your CCNA studies! Part of learning the details is mastering the fundamentals, so in this tutorial we’ll review the basics of VTP.

In show vtp status readouts, the “VTP Operating Mode” is set to “Server” by default. The more familiar term for VTP Operating Mode is simply VTP Mode, and Server is the default. It’s through the usage of VTP modes that we can place limits on which switches can delete and create VLANs.

In Server mode, a VTP switch can be used to create, modify, and delete VLANs. This means that a VTP deployment has to have at least one switch in Server mode, or VLAN creation will not be possible. Again, this is the default setting for Cisco switches.

Switches running in Client mode cannot be used to create, modify, or delete VLANs. Clients do listen for VTP advertisements and act accordingly when VTP advertisements notify the Client of VLAN changes.

To pass the CCNA exam and earn this important certification, you’ve got to know switching inside and out. While you’re learning all the basic switching theory, make sure to spend some time with the one of three switching modes Cisco routers can use.

Store-and-Forward is exactly what it sounds like. The entire frame will be stored before it is forwarded. This mode allows for the greatest amount of error checking, since a CRC (Cyclical Redundancy Check) is run against the frame before it is forwarded. If the frame contains an error, it is discarded. If there’s no problem with the frame, the frame is then forwarded to its proper destination.

While store-and-forward does perform error checking, the delay in processing the frame while this error check is run results in higher latency than the other modes you’re about to read about. The latency time can also vary, since not all frames are the same size.

Cut-through switching copies only the destination MAC address into its memory before beginning to forward the frame. Since the frame is being forwarded as soon as the destination MAC is read, there is less latency than store-and-forward. The drawback is that there is no error checking.

There is a middle ground, fragment-free switching. Only part of the frame is copied to memory before it is forwarded, but it’s the first 64 bytes of the frame, not just the destination MAC. (Why? Because if there is a problem with the frame, it’s most likely in the first 64 bytes.) There is a little more error checking than cut-through, but not as much latency as with store-and-forward.

Whether you’re on the road to the CCNA, CCNP, MCSE, or you’re on any other computer certification track, the odds are that sooner or later, you’re going to fail an exam. It’s happened to almost all of us, yours truly included. What you have to keep in mind in these times is that success is not a straight line. You’ve probably seen charts showing the growth of an industry or a business — you know, the ones that go from left to right, and look kind of jagged. The line goes up for a while, then down a bit, then up some more, then down a little.

The key? While every business has its setbacks, the net result is that the line goes up and progress is made. That’s how you want your certification pursuit and your career to go as well – upward!

I’m not asking you to be happy about failing an exam. You’re allowed to get mad for a few minutes, vow to never take another exam again, and be disappointed. What you’re not allowed to do is stay that way.
