Firewalls and Viruses

This week I learned about Firewalls and Viruses among other topics. I decided to write about these topics because they really interest me. However, some of the viruses out in the world right now scare me a lot. Although, I still would like to explain some things on this subject, so without further adieu let’s begin!

Let’s start with Firewalls. These are basically what attempts to protect your computer. Now, I say attempts but it actually does protect your computer from a lot of things and people, but not everyone and everything. In some instances, the firewall is a small inconvenience to the hackers. So, that is basically what a firewall is; protection.

Now, a virus is classified as something called Malware. Malware can be your worst nightmare or a minor nuisance. An example of a really bad virus is a Trojan Horse virus. This can come from pretty much anything, but the most common is a site that states it can rid your computer of viruses. Unfortunately, some people buy into this scam and the virus takes a hold of your computer. The only reason that the virus gains control of your computer is because the person downloaded a virus instead of a virus remover. The worst part of this virus is that it infects your computer with several different viruses.

Extra:

There are people known as White Hat SEO, Black Hat SEO, and Gray Hat SEOs. These people do many different things, but they all use hacking for different means. Let’s start with White Hats. White Hats are basically the “good guys,” because they hack things to discover security weaknesses and other things in computer networks and sites.

The Black Hat SEOs, however, are the “bad guys,” they use malicious software to hack into personal computers, and other networks and mainframes, to steal personal information. These are the people that typically use Trojan Horse viruses.

Then there were the Gray Hats. These people are like anti-heroes. They are very similar to Deadpool, because they hack for their own purposes but also for money. They are really more in the middle so they aren’t “bad” but they aren’t “good” either. They hack into personal computers too, but they don’t usually use malicious software like Black Hats.

How the World Wide Web works

Today I am writing about how the Internet/World Wide Web works. Most people refer to the “World Wide Web” as the Web. This, I guess you would call it, ”system” is used to pull information from websites around the world and display it on your computer screen. This is just the basic explanation of what the World Wide Web is. So, let’s delve a little bit deeper into what the Web does.

The Web would not work if it wasn’t global. This is because if one country had ownership of something this powerful, other countries around the world would fight to get rid of it. This would then create World War 3. Overall, that would be very bad, and I don’t think that would be the greatest thing for anyone.

The Web is spread globally via cables on the ocean floor. These work because they are checked on regularly. These cable connect the continents and are used as tunnels. They are used to make a connection that gives information a path to get to other places in the world. These cables are very similar to a tunnel through a mountain. They basically provide a shortcut through the ocean instead of having it sent by a messenger. Seeing as though the cables are spread out through the ocean, they need to be very long. This would seem as though it would be a very long time before your information reached your computer. However, this is not the case, because scientists have developed a better way to send information. They basically made a cable that takes information, breaks it down and then sends it with very high speed, and then the site or information then re-arranges itself into it’s proper order when it reaches your computer. So that is basically how the Web works.
