In order for computers, printers, etc. to communicate with each other on a network, each must have a different IP address. To make remembering these easier, the Domain Name System (DNS) translates these numeric IP addresses into names and web addresses that humans can actually decipher and remember. Instead of remembering one of the five numeric IP addresses to find, you type in the address as and DNS will go find the page you are looking for.
DNS is most commonly used for internet purposes, but private networks use DNS for other reasons as well. It works throughout multiple computers or databases. It can handle many types of name resolution requirements. With DNS the host name will stay the same even though the numerical IP address may be changing.
With all of the ways that DNS makes our lives easier in regards to networking, be that private networking or the internet, the overhead and IT management aspect of DNS are well worth it. I can’t imagine the headache of not having it in place.
DHCP (Dynamic Host Configuration Protocol) assigns IP addresses on the network. It provides the default gateway, subnet mask, and the DNS. Instead of IT administrators having to manually hand out static IP addresses and keeping track of all of them, DHCP takes care of it for them. Along with assigning them, DHCP will take back the IP address when it is no longer in use and reassign it when it is available.
With that being said, yes, DHCP saves headaches as well as DNS. However, it’s a little more tedious and costly. As far as overhead, sometimes it’s best to not use it. When using a couple computers it would be easier to assign static IP addresses and do things manually. On larger networks, DHCP makes more…...

The Balance of School and Work

...The Balance of School & Work During my junior year of high school I decided it was time to make my own money and begin to lean away from my parents. Although it is much easier to just ask for money, making my own taught me a lot more in the long run. I was forced to learn how to balance school work, social events, and work all at the same time. Having a job affected me in many positive ways. I learned what it was like to have an income of my own, I made many friends along the way, and I had to manage my time in order to stay on top of my studies. Taking on so many responsibilities at once and only being sixteen had its fair share of ups and downs, but when the weekly pay check came in it made it all worth it. Being a hostess at Texas Roadhouse was an ideal first job for someone like me. The paychecks were not much but the feeling of making money that I worked hard for was a feeling I had never experienced before. I was able to buy things I wanted and know that those items were 100% mine. My job taught me that making money is not always easy and made it me realize that when I asked my parents for money that it really did not just grow on trees. Without having my job in high school I believe I would have continued to rely on my parents for many of my wants. Making money was not the only thing I liked about having my job, along the way I made some really good friends. Working in a popular restaurant brought in people from many of the local high schools and colleges.......

The gain or at least the same score of all the students proved that this new way of teaching worked in this sample. The researcher would know that using this way of teaching this concept would work in the future for the researcher’s classroom. The researcher believes that if other classes were taught the same teaching method and the same pre-test and posttest and the data triangulated, the gain score would be very similar to the gain of the researcher’s students.

Not only you will start getting healthy but at the same time your body start going through witdrawls. Like what Tommy Chong is going through when he was in jail. A lot of people is on drugs, but the most addictive drug out there is pills that are legal, that are prescribe to us. So many people are on pills in this world. Marijuana helps post-traumatic stress disorder and that is a good thing. You don’t know what people go through in life. And it controls nausea, vomiting, and weight gain. It has been time when I was sick and I smoke to relieve the pain and it works. Weed doesn’t causes lung cancer but cigarettes do. It makes you fall asleep and get a lot of rest to get your strength back. The vomiting part I don’t know myself, maybe it helps you vomit. The reason we vomit is to get the poison out of our body. I know after I vomit, I feel a lot better. But most of the time I vomit after excessively drinking too much. Gaining weight, I can believe that you get the munchies after you smoke. I mean you be so hungry that you don’t want to share your snacks or food. I remember one time, I smoke so much that I came home and had two to three plates of food. I think we should give marijuana to those who try to starve their selves. After you put marijuana in their system, trust me they will eat.......

...Often when you speak to older adults they will tell you the school days were the best days of your life, this is not because the school days were the best of their lives, simply that they were conditioned into believing this. No adult can honestly believe that the best days of their lives were when they were treated with little or no respect, or when they were beaten with a slipper for speaking out of turn. If they truly believed that school days were so good then why did most of them leave school at 16? Fortunately today teachers don't beat us with old slippers of canes but does that really make school a better environment for the student? Well the most you could say is that it's an improvement. The fact is that the school environment is an unhealthy one; everyday you're faced with the same old routine, and even worse the same people. During your younger teenage years in the lower part of the school we are all faced with a huge task, not learning about algebra or Shakespeare, but the ultimately more important lesson of learning who we are, and who we want to be. So during these turbulent years we are not placed in a constructive, and helpful environment, we are forced into a volatile environment where the minority are bullied and the majority are too afraid to be different, we are surrounded by social stereotypes, greebos, skaters, townies goths, etc. The only way to truly be an individual is to shun other people's opinions of......

Successful firms, he contended, have to guard against the activities of existing rivals, buyers, suppliers, new entrants, and potential providers of substitute products. They must, furthermore, acquire a position within each industry where they gain the greatest profit from the value added to a product as it goes through each process stage to reach the consumer. They must adopt strategies of price competitiveness, product differentiation, or the application of either in specialist markets, and so gain the necessary competitive advantage over rivals and an effective barrier against market entry. Porter’s work was distinguished by a rigorous analytical framework and detailed investigation of various competitive scenarios. [pic] His reputation was enhanced by Competitive Advantage, which appeared in 1985, and it expounded further on the three strategies of price, differentiation and focus (M.E.Porter, Competitive Advantage: Creating and Sustaining Superior Performance, New York, 1985). It discussed in addition the ability to sustain a competitive advantage. His description of the value-chain was a useful conceptual advance.

The ultimate goal is becoming a millionaire and retiring at the age of forty and just drawing money from business production. However they really don’t understand the work it takes to make it a million dollar company. When these people are finally able to own a business they get a rude awakening. I am in no way trying to offend the typical business owner when I say, owning a business can be a challenging task that can cause many complications in your life and if you’re not careful they can change your life entirely. Over the last eight years I have watched my Aunt and Grandfather start a completely new hospice. My aunt is the main boss of the business, my grandfather just put in money so that she was able to actually start the business. Over those last eight years she has had some of the roughest times in her life. Being a single mother is hard enough, but then to start a business from scratch made it much more difficult to not only raise a family by herself. My aunt has had many problems in the last eight years and her business is now getting to the point of choosing what she does. I see some teenagers saying they want to own a business when they get older, but they only think of the money they can earn, the people they can tell what to do, and the fact that they can work when they want to work and no one can tell them otherwise.

The benefit of the market at this point will go to the consumer since they will be able to purchase more of the good than they were able to before.
