I remember an era where gaming notebooks were a special breed. Basically as I remember they were never the greatest selling laptops but being more significantly costly they were the greatest cash generating units. The most sought after laptops were the ones that were too overpriced to contemplate purchasing. They were pretty much desktop computer replacements and the quickest, best laptop computer you could acquire. I know we all got excited about them but the masses would never buy laptops that were so pricey. Recently all that has appeared to have transformed as the giant players have spotted the opportunities in gaming portables.
In my view they would get off by selling them at an increased price if they wanted. With such slim profits on other notebooks it is not a surprise they would like to be involved. Why would anybody buy laptops like this? Well big brands have the marketing money to educate them on that. What could local manufacturers possibly do if they are priced out of the market? I express this due to the fact that the technology which was once exclusive and overpriced is now becoming standard. I think customers would trust the larger manufacturers more if they get something high priced.
With that these portables are in addition perceived to be the best laptops already, even if they really are not. This is probably the last service that smaller companies can provide which the larger ones cannot. I really doubt buyers would prefer to have a similar specification like everyone else in this form of market. I believe the guys that purchase gaming notebooks typically know what they are looking for. For these types of consumers, the speed of a computer typically matter more than the design of it.
This could be interpreted as a positive change for the purchaser. In the near future top of the line equipment for your money will be the result of this change. Though I say that, I’m not so confident with my predictions. I doubt if the overall price of laptops will decline but new units are normally at particular price points. The larger companies have already started their own gaming laptop line, so all we can do now is sit back and watch.

Learn how to stop webpopups in their tracts.
Introduction
A new very intrusive form of unsolicited advertising is sadly sweeping the internet by storm. If you are running Microsoft Windows 2000 or Microsoft Windows XP, your Computer could be vulnerable to the new form of spam from the Windows Popup messaging service. These types of ads are known as messenger Spam or web Popup.
How it Works
This is made possible by a service called Windows Messenger which is installed by default on XP/2000/NT machines. While this service does not allow remote access to information on an individual’s computer, it provides a means for unsolicited messages or advertising.
How to Identify It
You can easily recognize the message boxes, as they will be labeled ‘Messenger Service’. You most likely do not have to be told how to make out the messages because it will be noticeable from the content, on the other hand some dishonest spammers make these messages look like real messages and request that you call toll telephone numbers!
Turn Off Messenger Service Manually
It only takes 4 simple steps to turn off the messenger service that is used to send messenger web popup ads. We should also note that the Messenger service is not related in any way to Windows Messenger or MSN Messenger.:
1. Go to Start, then Run and type in services.msc Click Ok
2. Scroll to Messenger, select it, right click it and choose Properties.
3. Under startup choose “Disabled”, and then choose Stop.
4. When stopped, click Ok.
Free Software
If you those simple steps are too hard for you to follow, there is free software available which can disable the messenger service for you. Ashampoo has released a free utility called AShampoo IP Spam Blocker.

Unless you have had your head in the sand lately you will have
heard of VOIP. Everyone seems to be talking about VOIP, but you
can be forgiven for probably not knowing much about it. VOIP
stands for Voice Over Internet Protocol and if you believe the
media hype this new phone service is about to revolutionise the
telecommunications market. As with a lot of new technological
developments there are a few causes for concerns that you
probably will not hear the marketing campaigns talk about.
What is it?
Just to give you a bit of background lets take a look at how
VOIP works for those of you that are unsure. You will need to
have a broadband Internet connection and to then open an account
with one of the many new VOIP providers. By having an account
with a VOIP provider you will be able to make a telephone call
through your computer and its Internet connection. Many VOIP
providers will allow you to call another user on their system
for free or phone a standard telephone number for a low cost.
Without getting too technical, VOIP works by converting your
voice into lots of small packets of data. These data packets are
then routed through the Internet to your VOIP provider’s
servers, and then onto the person you are calling. The reason
people are raving about this new service is the cost. It is much
cheaper than a standard fixed line telephone and you will also
get all the same services.
Is there a downside?
Now we do not want to put you off setting up a VOIP service, but
we think you should know a couple of things before you do.
Obviously low cost telephone calls is a very attractive offer,
but there are drawbacks to VOIP. One a major issue you need to
be aware of is that a VOIP service requires you to have a power
supply, as it requires your computer to be on. This means should
your electricity be out you will not be able to use your phone.
In some circumstances this could just be a minor inconvenience,
but in an emergency situation it may be much more serious. In
heavy storms and natural disasters electricity power is often
lost first. Would you really want to be without a phone?
Should your PC decide to stop working for whatever reason,
you’ll be left without a phone. Computers are prone to crashing
and should this happen, you will not be able to make any phone
calls. A concern of a different issue, is one of security.
Because your phone calls will be transported as data via the
Internet, you will be opening up the possibility of having your
phone system hacked into. A scary thought, especially for
business users.
As we said previously, it is not our intention to put you off
VOIP. We actually think it is a great service with so much going
for it. It is something that you should look into setting up,
and you can find out the most current developments from our
website (link below). We just want to give you the full picture
though so you can make an informed choice.
Take a look at VOIP Basics top ten things you need to know.
VOIP stands for Voice Over Internet Protocol.
VOIP or Voice Over Internet Protocol is a new way for you to
make a telephone call.
You will need to get yourself a broadband internet connection in
order to set up a VOIP service.
There are more and more companies setting up VOIP services.
Skype is probably the most known.
VOIP works by converting the sound of your voice into tiny
packets of data and then transmitting these via the internet.
Your PC needs to be on in order to use a VOIP service, which
could be a drawback should your electricity be off.
VOIP services provide extremely cheap calls.
Think about the possible security issues as your internet
connection could be hacked.
Should your PC get a virus this could stop you using the phone
if you are on a VOIP service.
Many VOIP providers will allow you to call another of there
users for free anywhere in the world.

Once you’ve got your CCNA, you’re ready to move on to the next level, the Professional certifications. For years, Cisco had one Professional certification, the Cisco Certified Network Professional (CCNP) certification. Over time, Cisco has expanded this level of certifications to include the Cisco Certified Security Professional (CCSP) and Cisco Certified Voice Professional (CCVP).
With security and voice being the two most rapidly expanding areas of today’s networks, some new CCNAs consider going after the CCSP or CCVP without first adding the CCNP to their resume.
While it’s temping to hurry up and get a Cisco security or voice certification, the best thing you can do for your networking career is achieve your CCNP certification first, then decide on the CCVP or CCSP.
Why? Because the CCNA is just the tip of a very large iceberg when it comes to routing and switching. It’s a very important accomplishment, and the CCNA is indeed the foundation of your networking career, but you need to add on to that level of understanding routing and switching before moving on to more specialized areas.
Two examples are OSPF and BGP. You learn about the theory of OSPF and some basic and intermediate configurations of that protocol in your CCNA studies, but the knowledge you acquire of OSPF in your CCNP studies is invaluable. As for BGP, there is no BGP in the CCNA curriculum, but it is a great idea to have some BGP knowledge in today’s networks. It’s also good for your career.
I know it is a huge temptation to go after the security and voice certifications while not paying attention to the CCNP. Do yourself a huge favor and add the tremendous amount of routing and switching knowledge needed for the CCNP to your knowledgebase, and you can then move on to the CCSP or CCVP. Even better, you’ll be better prepared to climb the biggest certification mountain around - the CCIE!

Your BSCI and CCNP exam success depends on knowing the details, and one such detail is knowing the proper way to summarize routes in OSPF. Route summarization is not just a test of your binary conversion abilities, but knowing where and when to summarize routes. It will not surprise any CCNA or CCNP certification candidate that OSPF gives us the most options for route summarization, and therefore more details to know!
OSPF offers us two options for route summarization configurations. In a previous tutorial, we looked at the “summary-address” command, and today we’ll look at the proper use of the “area range” command.
The “area range” command should be used on an Area Border Router (ABR) to summarize routes being advertised from one OSPF area to another. In this tutorial, R1 is acting as an ABR, with interfaces in both Area 0 and Area 1. Four loopbacks have been placed into R1’s Area 1.
R1(config)#router ospf 1
R1(config-router)#network 12.0.0.0 0.255.255.255 a 1
R1(config-router)#network 13.0.0.0 0.255.255.255 a 1
R1(config-router)#network 14.0.0.0 0.255.255.255 a 1
R1(config-router)#network 15.0.0.0 0.255.255.255 a 1
The routing table of an OSPF neighbor, R2, shows all four routes.
R2#show ip route ospf
12.0.0.0/32 is subnetted, 1 subnets
O IA 12.12.12.12 [110/65] via 172.12.123.1, 00:18:52, Serial0
13.0.0.0/32 is subnetted, 1 subnets
O IA 13.13.13.13 [110/65] via 172.12.123.1, 00:18:42, Serial0
14.0.0.0/32 is subnetted, 1 subnets
O IA 14.14.14.14 [110/65] via 172.12.123.1, 00:18:32, Serial0
15.0.0.0/32 is subnetted, 1 subnets
O IA 15.15.15.15 [110/65] via 172.12.123.1, 00:18:32, Serial0
To keep the routing tables of downstream routers smaller but still have the desired IP connectivity, we can use the area range command on R1 to summarize these four routes. The key to keep in mind with the area range command is that the area number given in the command is the area containing the destinations, NOT the area that will receive the summary route.
R1(config)#router ospf 1
R1(config-router)#area 1 range 12.0.0.0 252.0.0.0
R2 now shows a single summary route that can be used to reach all four remote networks.
R2#show ip route ospf
O IA 12.0.0.0/6 [110/65] via 172.12.123.1, 00:00:21, Serial0
Interestingly enough, there’s now an additional route in R1’s routing table.
R1#show ip route ospf
O 12.0.0.0/6 is a summary, 00:07:53, Null0
When you configure summary routes in OSPF, a route to null0 will be installed into the OSPF routing table of the router performing the summarization. This helps to prevent routing loops. Any packets destined for the routes that have been summarized will have a longer match in the routing table, and packets that do not match one of the summarized routes but do match the summary route will be dropped.
