Article Overview: It’s all about Internet and hackers.

Internet & hackers

Internet

The Internet was started in 1969. It started from local area network. Let me explain what is local area network. Computers connected with each other in a house or company makes local area network. On the other hand wide area network is the combination of countless LANs, wide area networks and individual machine around the world. All computers in the world when connected together make a network, which is known as Internet. These computers are connected through different ways via ISPs. Let me explain what is an ISP. Those companies who provide Internet service to computer users are called Internet service providers. These ISPs offer two types of connections. One is called slow speed or dialup and the other is known as high speed. Dialup gives a maximum speed of 56 kbps. High speed connections starts from 56kps and go behind 13mps (mega bit per second). ISPs provide different monthly packages for this service. Every package is priced according to the speed.

Suppose you have Internet service setup on your computer and you turn on it on, you are already on Internet. Just like in real world everybody has a name, on Internet every computer has a unique number, which is called IP (Internet Protocol) address. This number can be used to identify a computer. So if a computer in one part of the world wants to talk to another computer in the other part of the world, that machine will be using this number to talk to the other computer. That is how these computers and computer users can communicate with each other. If someone knows a computer number i.e. the IP address then he or she can connect to any computer (using the right tools) specially if that computer has a week security.

Hackers

Those computer users who gain unauthorized access to other people computers are called hackers. This is possible if the target computer is weak on security and the IP for the said computer is available. The question is how they get a computer's number i.e. IP address? Here are different possible ways of stealing or gaining access to IP address of a machine. Generally talking if someone has access to a computer then they can easily get it by punching a few simple commands. The IP address can be found during a chatting session. That's why Internet security is the greatest challenge for IT professionals. Spamming is another way of hacking a computer. In the Spam emails users are instructed to click on fake links and as soon as they click, scripts and spyware are download into their computer resulting in hacking.

Hackers use different programs to scan other people computers to get the computer number. In that case they never know whose computer number they are getting. In such cases the target computers are used for advertisements or identity theft. Let me explain how identity theft happens. A computer is a powerful tool in our life. We use it for checking emails, buy or sell items online; do our banking, schoolwork and many other daily life activities. All these activities are done through user id and password and that is what hackers usually search for. After they get the unique IP number, they download programs in other people computers. One bad fact about hacking is, location, they can be local or they may be sitting in other part of the world. Hackers can be blocked through different types of technologies i.e. hardware and software. In both cases there is one main idea behind it and that idea is called firewall. A firewall is like a security guard on the entrance of a building. It stops all unauthorized access to computer. Rules are setup on fire walled computers to allow or deny access through local and wide area network.

Internet is a great tool. Let's hope everybody use it for a better life. To me Internet is power. Long live Internet.

Would you happen to know how these hackers are destroying websites or targeting their victims?
Re: Alert to Forum! - It's truly unfortunate to see hackers try and destroy a perfectly peaceful, legitimate, and passionate group of people. It's almost as if they don't care or see that we enjoy discussing business with everyone. I'd like to one day, find them, beat them up, and lock them up. They are no better than harassers and bullies on the virtual cyber highways.
Re: Protect yourself from Hackers - Good tips ideasuniversity! So can I ask what kind of software protection you personally use for your computer? From my understanding, hackers are now moving onto attacking Macs more than PCs and also cell phones. Is having your cell phone data stolen a major concern for anyone? Does anyone have any cell phone "protection"?
Re: Alert to Forum! - A message board I read on a regular basis was hacked about a week ago... Occasionally Wikipedia has been down for an extended length of time... always makes me wonder if its been hacked and a backup is being quickly loaded... I dont understsand the mindset of these hackers, why destroy somene else's hard work just for the fun of proving you can do it? But those are the same kind of people who spray grafitti and break street lights and so on...hopefully if they're ever caught they go to jail!
