Erin Heard Fluency in IT Mrs. Murimi October 2nd, 2017 Viruses In 1982, a program called “Elk Cloner” was the first computer virus to appear “in the wild”, that is, outside the single computer or “computer” lab where it was created. It was written in 1981 by Richard Skrenta while in the ninth grade at Mount Lebanon High School near Pittsburg. The virus spread by infecting the Apple DOS 3.3 operating system using a technique now known as a boot sector virus. It was attached to a game which was then set to play. The 50th time the game was started, the virus was released, but instead of playing the game, it would change to a blank screen that displayed a poem named “Elk Cloner”. If a computer booted from an infected floppy disk, a copy of the …show more content…
When an uninfected disk was inserted into the computer, the entire DOS (including Elk Cloner) would be copied to the disk, allowing it to spread from disk to disk. To prevent the DOS from being continually re-written each time the disk was accessed, Elk Cloner also wrote a signature byte to the disk's directory, indicating that it had already been infected. Elk Cloner did not cause deliberate harm, but Apple DOS disks without a standard image had their reserved tracks overwritten. Social engineering did play a role due to the fact that the virus had an embedded download with a game you enjoyed playing. A virus hoax is a false warning about a virus on your computer. Normally, the warning arrives in an email note or is distributed through a note in a company’s internal network. Those notes are usually forwarded using distribution lists and they will typically suggest that the recipient forward the note to others. They are mostly harmless and accomplish nothing more than annoying people who identify it as a hoax and waste the time of people who forward the message. They use social engineering by exploiting users concern, ignorance, and disinclination to investigate before acting. You can prevent it by ignoring or deleting the email and do
This virus searches for a new vulnerable host in order to survive and carry the disease to the next victim. The critical aspect around the spread of a virus is how drastically the reproduction process occurs. Without being controlled, the contamination throughout any species causes the spread to take place in a toxic way, “On day one, there were two people. And then, four, and then, sixteen. In three months, it’s a billion.

Cloning is a DNA sequence, such as a gene, that is transferred from one organism to another and replicated by genetic engineering techniques. This means to reproduce or propagate asexually and some sexually. Cloning is made when you have several embryos and you try to duplicate them to produce more eggs which is called SCNT. SCNT (Somatic Cell Nuclear Transfer) is used so that they can take a piece of DNA from an egg and transfer it to another egg after the nucleus has been eliminated by an ultra violet beam. This technique is really hard to accomplish but can be done by well experienced scientists. There are many reasons why scientist would like to clone, and two of the main reasons are finding a cure to certain types of diseases and helping the endangered species come back to life like they once were.
On average the lifespan for a roe deer in the wild is 10 years old. When alarmed the roe deer will make a loud barking sound that much resembles a dog. Males may also make a low grunting noise. An alarmed roe deer will also flash its white rump patch. These patches differ between males and females with a female having a heart shape and the male having a kidney shape. During the breeding season bucks become aggressive, maintaining their territory around one or more does. Fights break out between these bucks and will often result in serious injury or death with the winner of the fight gaining access to the loser’s territory or doe. Before the buck is ready to mate courtship will take over where the buck chases the doe for some time then mating
Among all the communication mediums used in an organization, emails are used widely as an effective form of a business communication. From the company’s CEO to an employee of the business, emails are very easy and inexpensive. “Internal emails can function as an effective communication for sharing basic information, such as new cafeteria prices, paper use guidelines, or security precautions, for example. Sending simple messages to an entire workforce with just the click of a mouse is fast, easy, convenient and can save the company money”. (Lorette,
Treat any emails with respect & confidentiality i.e. do not share with anyone that should. Never walk away from your computer so that someone else can read your emails or even worse be in a position where someone could send an email on your behalf.
In the essay, Cloning Reality: Brave New World by Wesley J. Smith, a skewed view of the effects of cloning is presented. Wesley feels that cloning will end the perception of human life as sacred and ruin the great diversity that exists today. He feels that cloning may in fact, end human society as we know it, and create a horrible place where humans are simply a resource. I disagree with Wesley because I think that the positive effects of controlled human cloning can greatly improve the quality of life for humans today, and that these benefits far outweigh the potential drawbacks that could occur if cloning was misused.
News of source code theft jolted the software industry on February 12, 2004.2 Cyber criminals had stolen source code from Windows 2000 and Windows NT4.0. Windows 2000 and NT are the platforms on which the widely used home operating system of today, Windows XP, is based on. Luckily, only a small portion of code was stolen. Not nearly enough to build the entire Windows operating system. Through the use of peer-to-peer networking, the code was distributed in an underground hacker network. Eventually the source was spread onto public-access web sites, by which Microsoft confirmed the code was, indeed, real Windows code.
“200 years ago, there was around 16 million greater sage grouse; Today there may be fewer than 200,000” (Dantzker and Swartwout). The Greater Sage Grouse (Centrocercus urophasianus) is a magnificent bird that only lives in the Sagebrush-steppe habitat. This habitat is seen in the western part of the United States and also some area of North and South America. From the study above, it should be obvious that the greater sage grouse were considered endangered by Fish and Wildlife Organizations. However, on September 30th, 2015, the U.S. Fish and Wildlife Organization removed the sage grouse from the endangered “candidates” list, and stated that they would enforce plans to help the conservation of these birds. People should be aware that this is
The decision to monitor e-mail is left to the organization that provides the e-mail service to users. These organizations can range from educational institutions and private corporations, to governments and non-profit organizations. Each of these different types of organizations has a different agenda and goals, not only in general, but also for their members-and more specifically, for their members' e-mail. While educational institutions can provide e-mail facilities to their constituents for the purposes of convenience, employers almost always maintain e-mail facilities for the sole purpose of improving the on-the-job productivity of their employees.
Having first appeared in Russia in 2005, referred as Winlock, that successfully scammed over £10m from unsuspecting victims before the Russian authorities arrested 10 individuals for involvement in such hackings in 2010, however it hasn’t stop the growing number of the problem. With such profitable money to obtain, perpetrators have discovered new ways to spread the malware and to cash-in at the expense of victims.
