Computer network Essay The Internet is network of networks, linking computers to computers sharing the TCP/IP protocols. Each runs software to provide or â€Å"serve† information and access and view information. The internet is the transport vehicle for the information stored in files or documents on other computers. It is sometimes compared to a giant international plumbing system. The internet itself does not contain information. What it was found in is one of the computers linked to the internet. The Internet, A global computer network providing a variety of information and communication facilities, consisting of interconnected networks using standardized communication protocols. It is a network of networks that consists of millions of academic, government, private, business, public networks and, of local to global scope, that are linked by a broad array of electronic, wireless and optical networking technologies. The internet can have many services, like Electronic mail(e-mail) that permits you to send and receive mail, Telnet(remote login) that permits your computer to onto another computer and use it as if you were there, FTP(File Transfer Protocol) allows your computer to rapidly retrieve complex files intact from a remote computer and view or save them on your computer, etc. To access the internet by computer, you need a computer, a modem or other telecommunications link, and software to connect to an Internet Service Provider. The internet is indeed a wonderful, amazing and brilliant gift that has been given by science to humans. Presently in this modern era, the Internet plays a significant role in our daily human life. Whereas, we are seriously addicted to using the Internet in this century. Moreover, people like to spend plenty of our human lives. Ten years ago, the Internet was practically unheard of by most people. Today, the Internet is one of the most powerful tools throughout the world. The Internet is a collection of various services and resources. According to Russ Brock, a director and consultant at the Center for Innovation and Inquiry, the Internet is main components are E-mail and the World Wide Web. There’s a lot more to the Internet than E-mail, search engines, celerity web sites, up-to-the-second sports scores, and chat rooms full of risk discussions. The Net also ranks as one of today’s best business tools if it’s used adroitly. Almost all households contain the Internet; however, before people connect to the Internet, they need to be aware of its disadvantages and advantages. Many fear the Internet because of its disadvantages. They claim to not use the Internet because they are afraid of the possible consequences or are simply not interested. People who have yet connected to the Internet claim they are not missing anything. Today s technological society must realize, it is up to them to protect themselves on the Internet. Half of U. S. adults, or 94 million Americans, aren’t online. Children using the Internet have become a big concern. Most parents do not realize the dangers involved when their children log onto the Internet (Children and the Internet). When children are online, they can easily be lured into something dangerous. When children talk to others online, they do not realize they could actually be talking to a harmful person. As a result, there have been many cases where children have been convinced to meet people they have talked with online. In fact, stories seem to come out every week: a child or teenager lured into something foolish, dangerous, or even deadly on line. Cathy Cleaver of the Family Research Council claims that it is against the law for a molester to even attempt to find children online In addition, children may also receive pornography online by mistake; therefore, causing concern among parents everywhere. Whether surfing the Web, reading newsgroups, or using email, children can be exposed to extremely inappropriate material. Pornographic sites tend to make sure they are the first sites to be listed in any search area; thus, children come across such sites easily. A man from Pearl, Mississippi was arrested in 1996 for downloading pornographic images of children from the Internet. He was charged with 290 counts of child pornography). Some critics say that parents are responsible for their own children on the Internet because there are available services to protect children. To keep children safe, parents and teachers must be aware of the dangers.

History Of Computers :: essays research papers

History of Computers Introduction:   Ã‚  Ã‚  Ã‚  Ã‚  The electronic computer has now been used commercially for less than 25 years. It grew out of a search lasting centuries for a more accurate, faster way to perform calculations.   Ã‚  Ã‚  Ã‚  Ã‚  Primitive and ancient man used his fingers, shells, beads, sticks, and other objects to keep track of numbers and sums. The development of paper and writing instrumentsmade it easier to record data, but gave little aid in manipulating it. Manual Devices:   Ã‚  Ã‚  Ã‚  Ã‚  A computer is sometimes defined as a system that mechanizes the processing of information. Even a manual device may fall under this definition if they are constructed in such a way that moving them by hand can produce the desired answer. Example: Abacus:   Ã‚  Ã‚  Ã‚  Ã‚  The abacus is the oldest-known mechanical computing aid. Its origin is uncertain. Many countries claim to have invented it. It was used in China as early as the sixth century B.C. and in the mediterranean areain ancient Greek and Roman times. It is still used in many parts of the world.   Ã‚  Ã‚  Ã‚  Ã‚  The abacus consists of beads strung on rows of wires suspended within a rectangular frame. A common form has a piece of wood dividing the beads, with five beads on one side, and two on the other side of the wood on each wire. Calculating Machines and their Inventors:   Ã‚  Ã‚  Ã‚  Ã‚  Through the centuries, several mathematical geniuses invented machinesto aid them in their calculations. The machines were never widely used and generally had no direct path to the later development of electronic computers. Example: Pascal:   Ã‚  Ã‚  Ã‚  Ã‚  Blaise Pascal (1623-1662) a French matematician, invented the first mechanical adding machine at age 19 in 1642. He became tired of adding long columns of figures while helping his father, who had been appointed administrator of Rouen by Cardenal Richelieu. His device had teen toothed wheels and many gears. Rotating wheels developed sums. A carry lever advanced the next wheel to the left one position when a sum exceeded 10. Punched Card Development:   Ã‚  Ã‚  Ã‚  Ã‚  Many of us are surprised to learn that the punched card industry is almost 200 years old. Furthermore, the first use of punched cards wasn’t for data processing, but rather for process control. Example: Jacquard:   Ã‚  Ã‚  Ã‚  Ã‚  Joseph Marie Jacquard (1752-1834), a French Weaver, in 1804 developed the first completly automatic loom, controlled by punched cards. Fearing that the machine would produce unemployment, workers attacked and destroyed his machine at Lyon. Aided by Napoleon, Jacquard rebuilt his machine, which os credited with promoting a thriving textile industry in France through the 1800s.

Fireworks Factory Essay

Jerry Yu is an American born Chinese man with an MBA who runs a small family chain of businesses in New York. He is faced with a decision to invest in the Chinese fireworks industry. Jerry must assess the attractiveness of the fireworks industry along with the risks involved. Throughout this paper we will analyze the pros and cons of entering the market of Chinese fireworks. In our opinion, Jerry Yu should not invest in the Liuyang fireworks factory. While there are many factors that could give Jerry the opportunity to be successful, the low profit margin and the high instability of the market outweigh the chances of success. The regulations throughout the fireworks industry varies from market to market. For example, China’s domestic market has deregulated since 2005, while the American market remains regulated. The high competition paired with the low selling prices due to undercutting has caused the profit margin to decrease, especially for new entries. The reason for this is that the established fireworks companies have long term contracts with suppliers, causing Jerry to sell his fireworks at a lower price. Established companies also cause a problem because of their relationships with the raw material suppliers. Due to their longstanding relationships, these companies have a right to supplies before the new entries. This results in the new entries receiving lower quality materials, leading to a worse product and less safe working environment. Even though technology is involved in the production of the fireworks, the cheaper quality materials cause a greater risk of an accident during the manual mixing of powders, which is the most dangerous step. The risk of an accident is so high that most factories are built in rural areas near a water source with separated departments in case of an explosion. Another factor that should be considered is the environmental hazards of fireworks production and use. With an increase concern for the environment and â€Å"going green†, stricter regulations have been put into place. With the new restrictions and concern to avoid pollution, the consumption of and desire for fireworks could eventually fade away. Substitutes have already entered the market that are more environmental friendly. These substitutes include popping of red balloons and laser light shows. Considering all of the risks, along with the entrance of substitutes, we advise that Jerry Yu not invest in the Chinese fireworks industry. Jerry Yu has many factors to consider involving risk  associated with the Chinese fireworks industry; however, there are many advantages in investing that he should not overlook. The Chinese fireworks industry is a highly competitive market. With over 6,000 companies, it is hard to differentiate products. The attractiveness of investing in the industry is that there is easy entry. In Liuyang, there are over 400,000 laborers working in the industry, and this makes for low cost labor and easy access to skilled labor. While the majority of workers in China are not skilled, the residents in Liuyang have gained experience with producing fireworks. Jerry has an opportunity to use this to his advantage. If he can rework the business structure of the company previously run by the village, he can set his factory apart from the average family run and operated businesses. Jerry Yu must recognize that in 2009, the current market size is $675 million, and if he plays his cards the right way, he can grab a large portion of the market share. In order to do this, his factory should have a competitive advantage. The question is, how can he go about this? We believe that he can achieve this goal by building his factory to be different from all others in the industry and specializing specifically in fireworks instead of firecrackers. Jerry Yu needs to create a niche where he, and only he, has the ability to make the highest quality of fireworks in the world. He must create a marketing strategy that has not been introduced to the current market, and he must hire the most qualified engineers to make the safest and most extraordinary combination of fireworks that exists. In doing so, Jerry has an opportunity to push the technology bubble to a place that fireworks have never been before. Creating a more unique, high quality product that will blow the competition away will give Jerry the ability to set his prices higher than other manufacturers. Jerry does not need to concentrate his sales upon the low cost average firework sales that sell in bulk, but he must sell a few high quality fireworks that give him a large margin. He needs to stay away from the price competition, and the way he will do this is by creating a niche firework that the world has never seen before. One way that Jerry can set his factory apart from other firework competitors is to embrace the new and changing technologies. Instead of looking at lasers and music as negative competition, he can make an alliance with them. Jerry can team up with a laser light show and a music show to complement the firework display. Creating a bundle package for the most  elite firework show that the world has ever seen is an answer to the niche market that Jerry should pursue. Jerry Yu should also focus on brand advertising and brand awareness, so his brand of fireworks can stand out above the other businesses in the market. He could create a marketing campaign that emphasizes that his fireworks are the best in the world, as well as the safest. A major objective for Jerry Yu should be to aim for a specific, high paying target market. The competition is high in the basic firework industry, and entering this market would result in price gouging; this would be too hard for Jerry to gain market share at this level. He will have to set his product apart from what already exists. He should guarantee that his fireworks are the safest and highest quality, which can give him the competitive advantage to target high paying customers. For example, Jerry Yu does not need to concentrate his sales to the common buyers. He should aim to get his product to a popular show, such as the Beijing Olympics, or to high paying customers in the United States and Europe where the price is not a huge concern. In ensuring his high paying customers of safety and quality, there will be very few businesses, if any, that can compete with Jerry. While the objective of Jerry Yu should be to aim at a particular market, this goal is not in the best interest of Liuyang Firecrackers and Fireworks Industry Department to go that route. In our opinion, Jerry Yu should advise Liuyang to encourage its citizens to consolidate its family owned businesses into bigger corporations. As of now, one of the only ways to differentiate products is by undercutting other manufacturers’ prices. The entire industry should focus on a way that each company can pull away from price gouging and work together to make sure the prices stay at a constant medium that will benefit all of the manufacturers. One way businesses could do this is to designate certain types of fireworks and firecrackers to be made by specific manufacturers or areas. In doing so, the designated companies could increase productivity and steer clear of price gouging. After analyzing the circumstances associated with entering the Liuyang fireworks factory, we believe Jerry Yu should not invest his time and money into the market because the risks highly outweigh the benefits. The market is too unpredictable, restricted, and saturated to guarantee a successful investment. If Jerry Yu did take on this investment opportunity, the costs he would endure to improve the company would not be  worth it in the long run. With the industry being the way it is, it would be difficult for Jerry Yu to become profitable.

Relationship Between Gatsby And Daisy - 1327 Words

When a person’s greatest hope does not come true, it can not only leave them stuck and unsure what to do with their lives, but cause emotional damage as well. Putting all the eggs in one basket means that if the person loses the basket, he or she loses everything they essentially live for as well. Obviously, this leaves him or her in the lowest depths of despair. In The Great Gatsby, Fitzgerald once again uses the relationship between Gatsby and Daisy, this time to demonstrate how much hurt a broken dream can cause. Within the first hours of being reunited with his former love, Gatsby begins to suspect that the situation will not fall perfectly into place the way he imagined. Nick, after attending this awkward reunion, reflects, â€Å"There must have been moments even that afternoon when Daisy tumbled short of his dreams -- not through her own fault, but because of the colossal vitality of his illusion. It had gone beyond her, beyond everything... No amount of fire or freshne ss can challenge what a man will store up in his ghostly heart† (103). Although Daisy still appears as beautiful and charming as ever, Gatsby’s false image of her after several lonely years expands so much larger than life that the real Daisy plainly disappoints Gatsby. Fitzgerald strongly warns against the pitfalls of hope - once a person fixates on an idea, such as Gatsby did, reality cannot compete with the power the idea has over the person, leading to a delusional and unsatisfactory life in actuality.Show MoreRelatedThe Relationship Between Daisy And Gatsby By F.
