Free Essays on Spyware, The Newest Form Of Privacy Invasion Free Essays on Spyware, The Newest Form Of Privacy Invasion In a study of 3 million computers, over 83 million spyware programs were found. Spy-ware, which is deceitfully installed by malicious attackers, is an ever increasing problem among professional and home computer users worldwide. It not only causes performance problems for computers, but can also damage the computer’s hardware. It infects an estimated 80% of all computers worldwide, and many users have no idea what "spyware" is. Anyone who uses a computer should educate themselves on what spyware is, how it gets onto computers, and how to protect themselves. If people have no knowledge of what spyware is how can they protect their computer properly? Many people have heard about spyware and are purchasing programs to help protect their selves from it, but this is not always the best solution. Many legitimate software programs contain an information-gathering functionality that they need in order to perform properly. These include error reporting applications, troubleshooting and maintenance programs, security protocols, and Internet browsers. These small windows into computer’s security systems are there for legitimate programs that need some access to properly display their products and services, and if people install blocking tools that block all communication on those ports, then they also block the legitimate programs also. Spyware companies’ exploit this built in access to read personal or private information stored on computers. These programs can have devastating effects on a computer. Once a spyware program is installed on a computer it can be almost impossible to detect or remove. Sometimes multiple spyware programs can infect a computer and slow down the system to the point that it is almost useless. Spyware is the most commonly used tool for criminals committing identity theft. Spyware can perform many tasks, such as; recording keystrokes, recording passwords, and recording credit card numbers.

Family Delphinidae

Family Delphinidae Delphinidae is the family of animals commonly known as the dolphins. This is the largest family of cetaceans.Members of this family are commonly called dolphins or delphinids. The Family Delphinidae includes such recognizable species as the bottlenose dolphin, the killer whale (orca), the  Atlantic white-sided dolphin,  Pacific white-sided dolphin, spinner dolphin,  common dolphin, and pilot whales. Dolphins are vertebrates and marine mammals. Origin of the Word Delphinidae The word Delphinidae comes from the Latin word delphinus, meaning dolphin. Delphinidae Species Cetaceans in the Family Delphinidae are  Odontocetes or  toothed whales. There are  38 species  in this family.   Characteristics of Delphinidae The Delphinidae are generally fast, streamlined animals with a pronounced beak, or rostrum.   Dolphins have cone-shaped teeth, an important characteristic that distinguishes them from porpoises. They have one blowhole, which distinguishes them from baleen whales, which have a pair of blowholes.   Dolphins also use echolocation to find their prey. They have an organ in their head called a melon which they use to focus clicking sounds which they produce. The sounds bounce off objects around them, including prey. In addition to its use in finding prey, delphinids also use echolocation to communicate with other dolphins and to navigate. How Big Are Dolphins? According to the Encyclopedia of Marine Mammals, the Delphinidae can range in size from about 4 or 5 feet (e.g., Hectors dolphin and the spinner dolphin) to about 30 feet in length (the killer whale, or orca). Where Do Dolphins Live? Delphinids live in a wide range of habitats, from coastal to pelagic areas.   Dolphins in Captivity Dolphins, especially bottlenose dolphins, are kept in captivity in aquaria and marine parks. They are also kept in some facilities for research. Some of these animals are once-wild animals that came into a rehabilitation center and were unable to be released. The first marine park in the U.S. was  Marine Studios, now known as Marineland. This park began exhibiting bottlenose dolphins in the 1930s. Since dolphins were first displayed in aquaria, the practice has become more controversial, with activists and animal welfare advocates especially concerned about the stress levels and health of captive cetaceans, especially orcas. Dolphin Conservation Dolphins are also sometimes the victims of drive hunts, which have grown more widely known and controversial. In these hunts, dolphins are killed for their meat and to be sent to aquariums and marine parks. Even before that, people advocated for the protection of dolphins, who were dying by the thousands in nets used to catch tuna. This led to the development and marketing of dolphin-safe tuna. In the U.S., all dolphins are protected by the Marine Mammal Protection Act.   References and Further Information Committee on Taxonomy. 2014. List of marine mammal species and subspecies.
