Internet Security1 essays

Internet Security1 essays The Internet has become a greater medium of communication, data exchange, and entertainment over the past 5 years. With this widespread growth of Internet access, there come growing pains. These growing pains come in the form of people who are up to no good and want to ruin everybody elses experience on the net. High-speed connections also make it a very easy way for hackers to attack your pc in your daily life. In this report, I will discuss the types of Internet connections that are commonly used by consumers. I will also talk about the kinds of hackers that are out there. Each hacker has his or her own reason for doing it and by knowing that, prevention can be made simpler. I will discuss the types of Internet security programs that are available to everyday users. There are also hardware devices that arent as common in the home, but I will discuss their importance also. Finally, I will tell you how easily these programs can be implemented. I. Types of internet connections b. Permanent "all-the-time" connections c. Out-for-fun, harmless hackers b. Turning off PCs when not in use The Internet was a very unknown term to people ten years ago. This new information superhighway was reserved only to those who had the income or the need for data exchange between corporate locations. In the mid 1990s, companies like America Online and Prodigy created a easy connection to the Internet. These connections were called dial-up connection. They made use of a modem connected to your pc and by using your phone line, connected you to their services.

Bank records, shopping habits, and credit card information became common ground for people who hacked into personal computers. As the Internet spread to locally owned ISPs, or Interne...

Examples of Electrical, Thermal Conductors Insulators

Examples of Electrical, Thermal Conductors Insulators   A material that readily transmits energy is a conductor, while one that resist energy transfer is called an insulator. There are different types of conductors and insulators because there are different forms of energy. Materials that conduct electrons, protons, or ions are electrical conductors. They conduct electricity. Usually, electrical conductors have loosely bound electrons.  Materials that conduct heat are thermal conductors. Substances that transfer sound are acoustical conductors. There are corresponding insulators for each type of conductor. Many materials are both electrical and thermal conductors or insulators. However, there are exceptions, so dont assume just because a sample conducts (insulates) ​one form of energy that it behaves the same for other forms! Metals typically conduct both heat and electricity. Carbon conducts ​electricity as graphite, but insulates as diamond, so the form or allotrope of a material can be important.
