World Population Essay -- Environment Populated Essays Papers

World Population Works Cited Not Included Population causes a heated debate among many people. The world's population has exceeded 6.5 billion and continues to increase about another 76 million each year. The three most populated countries are China, India, and the United States. Scientists have become worried that the population will double within the next 50 years, exceeding 12 billion people. With scarce natural resources and the strain that a doubling in population will cause on food availability, people become more wary about population control. What is population control? Population Control is the practice of limiting population increase, usually by reducing the birth rate (www.wikipedia.org). The first country to adopt a population control policy was India, though that did not stop the country from passing the 1 billion mark. In 1952, 6.5 million rupees were made available to conduct studies in fertility and family planning (Samuel, 54). For the first five years (1952-1956), the Indian Government was not sure what to do with the information and the population continued to grow at a rate of two per cent per year. After 1962, the Indian Government decided to limit the size of families, yet did not have to put effort into persuading the people to favor the idea. However, the people lacked a serious motivation to limit their procreation (Samuel, 56). India's population continued to grow. Contraceptives were also introduced, yet even after the education of the people, they went unused. The women were not given a choice when it came to reproduction. The men did not want to use the contraceptives, and they could not be forced by their partners. It was said that without an improv ed standard of living and improved education, ... ...t. The United States can support its population, but is still having problems with pollution. The hungry can be fed, the poor can be clothed, but the pollution is still much higher that desirable. The issue becomes a question of availability of natural resources and food. The question becomes "How do we produce more for a growing population on less land with less available water?" Is it ethical to control population? Should the government of any country mandate contraceptives or limit the amount of children a family can have? Does this remove the agency of the people? Can people themselves be trusted with the agency of how often they can procreate and how they feed, shelter, and clothe their children? It seems as though if population goes unchecked, mankind will wring out every last drop the Earth has to offer. The question then becomes: "What will we do then?"

A Person Who Inspire Me the Most

Songsnumber-onesinglesAndre Hill September 30, 2010 3rd period The person that inspires me most is my mom. The reason I say this is because she’s a strong black woman and she stands independently facing all odds. She inspires me to be the best I can be and to always give my all in whatever I’m doing. Whenever I need something, all I have to do is ask and I know if it’s possible, she’ll provide it. It’s always been like that with her and not with just me, but all of my brothers. I think the reason we may act uncivilized when dealing with authority is because we know we have a mother who’ll bail us out 9 times out of 10.If I didn’t have her, I would probably be a drop out because I wouldn’t have anyone in my ear telling me to get my grades up. My mom tells me what to do and she means just that. She has her flaws like every human does but they aren’t easy to spot in her. We’re not rich or close to it but from everythi ng I have you wouldn’t be able to tell. I never go without anything I need or in a lot of cases, anything I want. I know she would give me her last dollar. For example†¦if my mom and I both wanted a candy bar and she only had two dollars on her, without a doubt she would buy it for me.She thinks of others before herself a lot and that could cause people to try to run over you but not with my mom. My mom is very smart and she pushes education to the max in my household. When I bring home bad grades I know it hurts her just as much as it hurts me, maybe a lot more actually. I always use manners and that’s because she tells me that education and respect will take me far in life. And that it would make people respect me. I want to be an R&B singer when I grow up and my mom tells me I can be anything I want to be.I don’t know if she really believes that or if she’s just saying it because it sounds good, but I know that that’s the kind of motivation I need. If I don’t have any support from anyone else, I know I’ll have some from her. I can count on my mom for anything. If I was to fall from a plane I’m willing to bet any amount of money my mother would be there to catch me, not letting a strand of my hair touch the ground. I’m not Andre Hill September 30, 2010 3rd period saying that she’s a body builder or anything like that. I’m just trying to explain the love she has for me in words.Her love makes me want to be like her and to treat my kids in the future the way my mom treats me. I want to be able to give that type of love to everyone. If the world had that type of love there would be no tears falling or violence. I try to make the right decisions to satisfy my mom and myself. I don’t want to put her thru anything that would cause her to hurt. . I mean she’s wonderful and I wouldn’t trade her for anything or anyone in the world. I love my mom to death and she ins pires me more than any celebrity or person in the past could ever do.

Networks Essays - Local Area Networks, IEEE Standards, Free Essays Networks Network, in computer science, techniques, physical connections, and computer programs used to link two or more computers. Network users are able to share files, printers, and other resources; send electronic messages; and run programs on other computers. A network has three layers of components: application software, network software, and network hardware. Application software consists of computer programs that interface with network users and permit the sharing of information, such as files, graphics, and video, and resources, such as printers and disks. One type of application software is called client-server. Client computers send requests for information or requests to use resources to other computers, called servers, that control data and applications. Another type of application software is called peer-to-peer. In a peer-to-peer network, computers send messages and requests directly to one another without a server intermediary. Network software consists of computer programs that establish protocols, or rules, for computers to talk to one another. These protocols are carried out by sending and receiving formatted instructions of data called packets. Protocols make logical connections between network applications, direct the movement of packets through the physical network, and minimize the possibility of collisions between packets sent at the same time. Network hardware is made up of the physical components that connect computers. Two important components are the transmission media that carry the computer's signals, typically on wires or fiber-optic cables, and the network adapter, which accesses the physical media that link computers, receives packets from network software, and transmits instructions and requests to other computers. Transmitted information is in the form of binary digits, or bits (1s and 0s), which the computer's electronic circuitry can process. Network Connections A network has two types of connections: physical connections that let computers directly transmit and receive signals and logical, or virtual, connections that allow computer applications, such as word processors, to exchange information. Physical connections are defined by the medium used to carry the signal, the geometric arrangement of the computers (topology), and the method used to share information. Logical connections are created by network protocols and allow data sharing between applications on different types of computers, such as an Apple Macintosh and an International Business Machines Corporation (IBM) personal computer (PC), in a network. Some logical connections use client-server application software and are primarily for file and printer sharing. The Transmission Control Protocol/Internet Protocol (TCP/IP) suite, originally developed by the United States Department of Defense, is the set of logical connections used by the Internet, the worldwide consortium of computer networks. TCP/IP, based on peer-to-peer application software, creates a connection between any two computers. Media The medium used to transmit information limits the speed of the network, the effective distance between computers, and the network topology. Copper wires and coaxial cable provide transmission speeds of a few thousand bits per second for long distances and about 100 million bits per second (Mbps) for short distances. Optical fibers carry 100 million to 1 billion bits of information per second over long distances. Topology Common topologies used to arrange computers in a network are point-to-point, bus, star, and ring. Point-to-point topology is the simplest, consisting of two connected computers. The bus topology is composed of a single link connected to many computers. All computers on this common connection receive all signals transmitted by any attached computer. The star topology connects many computers to a common hub computer. This hub can be passive, repeating any input to all computers similar to the bus topology, or it can be active, selectively switching inputs to specific destination computers. The ring topology uses multiple links to form a circle of computers. Each link carries information in one direction. Information moves around the ring in sequence from its source to its destination (see Computer Architecture). Local area networks (LANs), which connect computers separated by short distances, such as in an office or a university campus, commonly use bus, star, or ring topologies. Wide area networks (WANs), which connect distant equipment across the country or internationally, often use special leased telephone lines as point-to-point links. Sharing Information When computers share physical connections to transmit information packets, a set of Media Access Control (MAC) protocols are used to allow information to flow smoothly through the network. An efficient MAC protocol ensures
