Understanding firewalls

Many people actually misunderstood the function of the firewalls. People usually think that firewalls are used to block connections on certain ports or applications. That’s a part of firewall function but the main function of a firewall is packet analyzer or packet filtering like some people usually refer to. Routers can also be used to block specific ports using access list control or usually know as ACL.


To help you understand what firewall is all about, you can read this article titled Understanding Computer Firewalls. The article is really great in my opinion since it’s explained computer firewalls in plain English. So it’s really easy to understand even for people with no computer background. The article also talks about computer history briefly from the start of new age computer era and the emergence of computer viruses.

It also talks about why firewall came into the picture in the first hand when anti viruses can’t no longer cope with the worms and viruses which developed rapidly, growing fast and getting more complex each day. The article also explained what type of firewalls in the market these days, how it is implemented and why is it so important to have a firewall these days, even for a personal computer and not limited to only corporate networks.

Please take your time to read and understand the article. I hope you can get some new knowledge from the article and feel free to comment if you have anything to ask.

It’s a video on how people tend to go online for an eyeglasses instead of going to the local optometrist. Starting from $8 for a pair of eyeglasses, it would be madly cheap considering a visit to the optometrist for a new glasses.

I like my eyeglasses to be plain and simple but I don’t know about others. Maybe I’ll buy all three of them and use them alternately. Since I wear eyeglasses on daily basis, it’s good to have a spare one too.

Blog advertising VS Web directories

I was looking for some additional information regarding web directories and how to optimize their usage for my upcoming blog post. While looking around on the net, I stumbled upon a nice article on blog advertising versus web directories.

I talked about promoting your blog using web directories in my previous post and this article currently discussing, what is the effective way to market your product. Is it using web directories or by using blog advertising. Well, it has it’s own advantages and disadvantages. According to the article, by using blog advertising, you will create an awareness of your product. For instance, by promoting your product through the blog post, blog readers won’t necessarily buy your product unless they feel it’s important for them but they might spread it out to their friends or suggesting it to their friends in case it came out in some of their conversations.

On the other hand, by using directories, people who has the needs or looking for the specific product will look into the directories for more information like the location of the product, the price and the benefits of using it. The article is just comparing the idea of two different types of product promotion, it doesn’t necessarily mean you can’t use them both! You can also read on the article SEO tips including descriptive text and hyperlinks too. It will greatly help your cause in your product promotion.
