What is a VIRUS
Virus (computer), self-duplicating computer program that interferes
with a computer's hardware or operating system (the basic software
that runs the computer). Viruses are designed to duplicate or
replicate themselves and to avoid detection. Like any other computer
program, a virus must be executed for it to function-that is, it must
be located in the computer's memory, and the computer must then follow
the virus's instructions. These instructions are called the payload of
the virus. The payload may disrupt or change data files, display an
irrelevant or unwanted message, or cause the operating system to
malfunction.
Computer viruses activate when the instructions-or executable
code-that run programs are opened. Once a virus is active, it may
replicate by various means and tries to infect the computer's files or
the operating system. For example, it may copy parts of itself to
floppy disks, to the computer's hard drive, into legitimate computer
programs, or it may attach itself to e-mail messages and spread across
computer networks by infecting other shared drives. Infection is much
more frequent in PCs than in professional mainframe systems because
programs on PCs are exchanged primarily by means of floppy disks,
e-mail, or over unregulated computer networks.
Viruses operate, replicate, and deliver their payloads only when they
are run. Therefore, if a computer is simply attached to an infected
computer network or downloading an infected program, it will not
necessarily become infected. Typically a computer user is not likely
to knowingly run potentially harmful computer code. However, viruses
often trick the computer's operating system or the computer user into
running the viral program.
Some viruses have the ability to attach themselves to otherwise
legitimate programs. This attachment may occur when the legitimate
program is created, opened, or modified. When that program is run, so
is the virus. Viruses can also reside on portions of the hard disk or
floppy disk that load and run the operating system when the computer
is started, and such viruses thereby are run automatically. In
computer networks, some viruses hide in the software that allows the
user to log on (gain access to)
Types of VIRUS
There are five categories of viruses: parasitic or file viruses,
bootstrap sector, multi-partite, macro, and script viruses.
Parasitic or file viruses infect executable files or programs in the
computer. These files are often identified by the extension .exe in
the name of the computer file. File viruses leave the contents of the
host program unchanged but attach to the host in such a way that the
virus code is run first. These viruses can be either direct-action or
resident. A direct-action virus selects one or more programs to infect

Over the past fifty years Japan has seen significant changes in all aspects of its society and the way it interacts with the outside world. For example, despite suffering a defeat in World War II, Japan soon became one of Asia’s greatest economic powers. In Japan in Transformation, 1952 - 2000, Jeffrey Kingston focuses on various aspects of change in Japanese society and politics in the period after World War II. These include the effect of the US occupation, analysis of postwar politics, the economic boom, changes in demographics, the treatment of women, and foreign policy and security issues. Throughout the book, the author tries and often succeeds to explain many of these changes as part of the legacy of the occupation. All in all, Jeffrey Kingston gives a thorough economic, politic and social analysis of this crucial period in Japanese history.
Beginning in the early seventeenth century, Japan went from being one of the driving forces of technological and military power in the modern world to becoming outdated, old due to a lack of technological innovation. From this Japan was able to outlast the hard times, becoming once again becoming technological powerhouse. This was because, as stated in the book, “The Lexus and the Olive Tree” by author Thomas L. Friedman, they were able to find a happy median between the Lexus and the olive tree, in other words, new ideas and technology, while still maintaining traditional values of culture and race, both politically and socially. Japan was able to rebound, and regain political, social and economic stability and prosper in each after decades of internal conflict and turmoil because they, unlike similar contemporary non-western civilizations, focused on balancing new reforms with older, more historical governmental traditions.
With the gradual decline of the Tokugawa Shogunate and the restoration of the Imperial title, Japan began its second phase of foreign borrowing by entering ‘secondary civilization,’ or industrial society (Suzuki, 1995 p.773). Beginning in the late Tokugawa period, the power of the shogun and the damiyos progressively began diminishing under political pressure and the deteriorating financial condition of the nation. Dissatisfied with the conditions, the people began leaning towards the restoration of the nation as an Empire, which occurred in 1867-68 with the resignation of Tokugawa Yoshinobu (15th Tokugawa Shogun), marking the beginning of the Meiji Restoration. The transfer of power to the Emperor proceeded smoothly, indicating the beginning of Japan’s radical influence and changes from the west. At the beginning of the Meiji period, Japan was primarily an agricultural nation with a weak military and scarce technological development still largely traditional in nature. Power was transferred into the hands of noble samurai that had opposed Tokugawa rule, acting in the name of the Em...
Emperor Meiji helped with the evolution of Japan because he helped advance guns and that helped them in wars and getting colonized by other countries. Japan has always been changing and trying to fit in the with the outside world. For Japan to be part of the outside world, they had to make friends with the other countries. 2 years after the Meiji Period ended, World War 1 began and was dragged into the fight. What Emperor Meiji did to advance Japan helped Japan survive the war because they had better firearms and they were connected to the world so they could ask for
The inception of the Tokugawa Shogunate around 1600 would reduce the impact of foreign relations throughout Japanese society. This bulwark helped resist change and development in Japan, although it continued throughout the western world. Following two hundred years of self imposed seclusion from the rest of the world, the forceful re-entry of the foreigner brought about considerable change in Japan. While managing the foreign threat, there was also an imbalance of power in the current feudal system of the Tokugawa Shogunate. This imbalance created uncertainty for Japan and the imperialistic foreigners. This imbalance and uncertainty would lead to the end of the Tokugawa Shogunate and the emergence of the Meiji Restoration. However, to understand the transition between the current Shogunate government and the modernization through the Meiji Restoration, it is imperative to realize not only the necessity of modernization but also difficulties modernizing presented. To achieve modernization, Japan would have to abandon or modify various traditional cultural institutions and ideologies which were weakening the Japanese Nation.
With emerging Western culture, Japanese foods expanded to accommodate the use of meat to fit the preference of Japanese. New industrial technology from America and Europe provided the base of Japan’s technology, leading to today’s modern and developed country with the continuous improvement. With major changes in Japanese diet and technology from emerging Western culture, Japan gained social and economic benefits, allowing the country to be the great powerhouse it is today.
During the Meiji Restoration, Japan transformed into a strong industrialized nation by adopting the Western political, cultural, and technological ideas. Japan was the “only non-Western country to industrialize in the nineteenth century and that, moreover, she did so in an extremely short time” (Sugiyama 1). Japan’s social, political, and economic aspects were all affected by the Western technologies to transform Japan into an industrialized nation (Wittner 1). By adopting the Western ideas during the Meiji Restoration, Japan has turned into a powerful industrialized nation by becoming an “international political player in the 1880s” (Wittner 1).
...ty for one that better suited its capitalistic tendency. That opportunity came in1868 when the Meiji imperial rule was able to overthrow the Tokugawa regime, setting off a political, economic, social and cultural change that transformed Japan. As Japan embraced modernity with full force, some began to realize the negative impact of modernization on the rural life, social structure and most importantly on its culture, blaming it on the western influence on its modernization. Thus as Japan neared World War II, it embraced a new sense of modernization, one that was separate from westernization, creating a nationalistic and fascist government policy. Japanese society is characteristic of plurality and opposing value systems coexisting. As new ideals and institutions arise, Japan sees itself transforming and changing at the hands of internal and external forces.
At the Aim Higher College there have been recently discovered malware on the campus systems that are due to many recent attacks. I used an Anti-virus protection software called AVG on the computer systems on campus and ran a whole computer scan. The results came back very quick of numbers of malware being high and medium priorities that these should not be taken lightly. Furthermore, the scan found many viruses, Trojans, and malicious software and applications.
Known as the most widespread and most common nutritional disease in major developing countries Kwashiorkor is a very serious condition. The condition of Kwashiorkor is a form of malnutrition where a young child is not getting the protein they need in their diet, yet at the same time they are getting enough calories. It usually affects children between the ages of one to three, but studies show it can develop at any age ("Human nutrition in the developing world", n.d.). While the disease is rarely seen here in the United States and developing countries, it is a very dominant disease and very wide spread in sub-suburban Africa, Southeast Asia and Central America ("Human nutrition in the developing world", n.d.). When this disease does present itself in the United Stat...
In order to prevent kwashiorkor from ever developing, it is important to make sure to follow the nutritional guidelines and have a balanced diet of carbohydrates, fat, and protein. Kwashiorkor can most simply be prevented by making sure that a child eats enough protein after they are weaned off of their mother’s milk (Rossouw 1989). Often times, in third world countries the children are weaned off their mother’s milk and then put onto a maize diet that does not offer adequate amounts of protein rich food. The Estimated Average Requirement (EAR) “for protein is 0.66 grams of protein/kg of body weight. The EAR for protein increases during pregnancy, breastfeeding, period of rapid growth, or recovery from serious illnesses, blood losses, and burns” (Schiff 2013). The Center for Disease Control and Prevention (CDC) recommends that 10 to 35 percent of a person’s daily caloric intake come from protein. Furthermore, in order to prevent kwashiorkor from developing, children ages 1-3 years need to have 5-20 percent of their energy from protein, children ages 4-18 years need 10-30 percent from protein, and adults need 10-35 percent protein. In other words, kwashiorkor is an avertible disease that can be prevented if infants and children are consuming at
Malicious software in short known as Malware. It is also known as computer Contaminant. Similar to biological parasite, malware also reside in a Host. Malware will get installed on host without user’s consent. Generally a software is considered malware based on the intent of the creator...
In children, under nutrition manifests as underweight and stunting (short stature), while severely undernourished children present with the symptoms and signs that characterize conditions known as kwashiorkor, marasmus or marasmic-kwashiorkor.
Peking Opera is said to be a live “encyclopedia of Chinese Culture” (Wertz). Because of this, and many other highly regarded qualities, China has made the Peking opera it’s “national opera” (Wertz). The Beijing Opera is such an important part of Chinese culture that “Beijing Opera Month” has been declared (Wertz).
