Computer Crime Essays - Hacker, Phreaking, Hacking, Free Essays

Computer Crime Essays - Hacker, Phreaking, Hacking, Free Essays Computer Crime Computer Crime It's the weekend, you have nothing to do so you decide to play around on your computer. You turn it on and then start up, you start calling people with your modem, connecting to another world, with people just like you at a button press away. This is all fine but what happens when you start getting into other peoples computer files. Then it becomes a crime, but what is a computer crime really, obviously it involves the use of a computer but what are these crimes. Well they are: Hacking, Phreaking, & Software Piracy. To begin I will start with Hacking, what is hacking. Hacking is basically using your computer to Hack your way into another. They use programs called scanners which randomly dials numbers any generating tones or carriers are recorded. These numbers are looked at by hackers and then used again, when the hacker calls up the number and gets on he's presented with a logon prompt, this is where the hacking really begins, the hacker tries to bypass this anyway he knows how to and tries to gain access to the system. Why do they do it, well lets go to a book and see Avid young computer hackers in their preteens and teens are frequently involved in computer crimes that take the form of trespassing, invasion of privacy, or vandalism. Quite often they are mearly out for a fun and games evening, and they get entangled in the illegal use of their machines without realizing the full import of what they are doing , I have a hard time believing that so lets see what a hacker has to say about what he does Just as they were enthraled with their pursuit of information, so are we. The thrill of the hack is not in breaking the law, it's in the pursuit and capture of knowledge. , as you can see the hacker doesn't go out to do destroy things although some do. It's in the pursuit of knowledge. Of course this is still against the law. But where did all of this start, MIT is where hacking started the people there would learn and explore computer systems all around the world. In the views of professional hacking is like drugs or any other addictive substance, it's an addiction for the mind and once started it's difficult to stop. This could be true, as hackers know what they are doing is wrong and they know odds are they will be caught. But as I mentioned some hackers are just above average criminals, using there skills to break in banks and other places where they can get money, or where they can destroy information. What a hacker does at a bank is take a few cents or even a few fractions of a cents from many different accounts this may seem like nothing but when all compiled can be alot. A stick up robber averages about $8,000 each job, and he has to put his life and personal freedom on the line to do it while the computer hacker in the comfort of his own living room averages $500,000 a job. As for people destroying information, this is for taking some one down, destruction of data could end a business which for some is very attractive. It can cost a company thousands of dollars to restore the damage done. Now that you have an understanding of what a hacker is, it time to move on to someone closely associates with a hacker. This is a Phreak, but what is that. For the answer we turn to the what is known as the Official Phreakers Manual Phreak [fr'eek] 1. The action of using mischievous and mostly illegal ways in order to not pay for some sort of telecommunications bill, order, transfer, or other service. It often involves usage of highly illegal boxes and machines in order to defeat the security that is set up to avoid this sort of happening. [fr'eaking] v. 2. A person who uses the above methods of destruction and chaos in order to make a better life for all. A true phreaker will not go against his fellows or narc on people who have ragged on him or do anything termed to be dishonourable

How to Make Instant Snow From Boiling Water

How to Make Instant Snow From Boiling Water You probably know that you can make snow using a pressure washer. But did you know that you can also make snow from boiling water?  Snow, after all, is literally precipitation that falls as frozen water, and boiling water is water that is on the verge of becoming water vapor. Its incredibly easy to make instant snow from boiling water. All you have to do is follow the steps below. Materials You only need two things to turn boiling water into snow: Freshly boiled waterReally cold outdoor temperatures, around -30 degrees Fahrenheit The Snow-Making Process Simply boil the water, go outside and  brave the frigid temperatures, and toss a cupful or pot of boiling water into the air. Its important that the water be as close to boiling and the outside air be as cold as possible. The effect is less spectacular or wont work if the water temperature drops below 200 degrees Fahrenheit or if the air temperature climbs above -25 degrees Fahrenheit. Be safe and protect your hands from splashes. Also, dont throw the water at people. If it is sufficiently cold, there shouldnt be a problem, but if your concept of the temperature is mistaken, you could end up causing a dangerous accident. Always be careful when handling boiling water. How It Works Boiling water is water that is at the point of changing from a liquid into water vapor. Boiling water has the same vapor pressure as the air around it, so it has plenty of surface area to  expose to a freezing temperature. The large surface area means its much easier to freeze the water than if it were a liquid ball. This is why it is easier to freeze a thin layer of water than a thick  sheet of water. Its also the reason youd freeze to death more slowly curled up into a ball than if you were to lie spread eagle in the snow. What to Expect If you want to see boiling water turn into snow before you attempt this experiment, you can view a demonstration on the Weather Channel. The video shows a person holding a pot of boiling water and then tossing the scalding liquid into the air. An instant later youll see a cloud of snow crystals falling to the ground. I could watch this all day, the announcer says as she introduces the video, which was shot at  Mount Washington, New Hampshire, the highest mountain in New England. The announcer notes before the video begins that the snow-making folks actually performed the experiment three times- once with a measuring cup, once with a mug, and once with a pot (which is the effort captured in the video). Ideal Conditions In the demonstration video, the temperature of the water was 200 degrees Fahrenheit, and the temperature outside was a frosty -34.8 degrees. The experimenters said that they had diminished success when the water temperature dropped below 200 degrees and when the outside temperature rose above -25 degrees. Of course, if you dont want to go through all of this, and you still want to make snow- or if the temperature outside  is just too warm- you can  make  fake snow  using a common polymer while staying warm and toasty indoors.
