Four Basic Topologies Network And Summarize
Four Basic Topologies Network And Summarize Nowadays, there have several types of network topologies with different characteristic, price and level, it was very important to choose a suitable network. Now we are going to discuss four basic network topologies : Bus, Ring, Star and Mesh. Lets discuss bus topologies first, bus network topologies is a single cable which use to connect to different points between network, as it only have one channel to support the bus network for communication, so the total capacity will send to all the points averagely. When a point want to send instructions to another point, it will announce a message to all the points thru wire and all the points will see it but only the destination point will receive and return the message to the sender point, other points will not give any response. Bus network topologies are cheaper than other network topologies because it use less cable and materie and also the installation is easier than other topologies. But because it is a single cable, when there have many points connect to the device, it will slow down the transmission speed and the total capacity. On the other hand, once the network have problem, it cost many times to fix it as you have to check all the cable connection to find out the problems. Also in a bus topology, once a single connection failure, it will stop the passage between all points. (The image of the About.com guide) Second topologies which we are going to discuss is Ring topology. In a ring network, each apparatus connected to two users for communication purpose. It looks like a circle and the message move around the circle to each point use single direction. Each node connect to its own cable to the Medium Attachment Unit (MAU). Ring network topology is easy to install and reconfigure and also easy to add new node as only two connections need changes. However, Ring network is not too convenience for the user as the data have to pass through all the points before getting to the destination. For example, if one network have six user, when the A computer want to send message to F computer, it have to pass through B, C, D, E computer and then to F. And if one network failure, whole network will disable because it only have single pathway to transmit the data. (The image of the About.com guide ) The third network topology is Star. Star network is one of the most usual computer network topologies. It features a central connection point call hub or concentrator (Bruce A Hallberg 2005) and it will radiate to other points. The characteristic of Star network is the hub or concentrator work as a central union to provide different route for signal send out to any two sites. Data on star network will send the message to hub or concentrator first before send to the destination point. Hub or concentrator works like a repeater for the data flow. In the star network topology, if one connection stoppage, only one node will lose the connection from this site and it wont be affect to other networks. On the other hand, it will be easy to find out the problem as all network is obey to hub, so once the network out of service, mostly it must be some problem with the hub and the problem can be fix quickly instead of checking all the points. Furthermore, as hub is control everything included add or remove devices, that means Star network is easy to install. If you want to add some new devices to the network, just need to connect the cable to hub and other computer will detect the devices and can use it. It save lots times to install the devices to all computers separately in the network. Moreover, hub can also be act as a backup file, once the network is not work, you can move to another computer and using the data from hub. Although star network is more stable than other network topology, but star network is more expensive as it needs more wires to support the network. And because it is fully obey to hub, once there have many nodes, the network maybe slow down. (The image of the Florida Center for Instructional Technology College of Education, University of South Florid 1997.) Last network topology we have to share is Mesh. Mesh network is a network where all the nodes connected to each other with different ways, maybe single hop or multiple hops. In a mesh network, if one node or cable have problem occur, there will have another way to communicate with other node, it wont be halt the whole network. Mesh network will also default the short way automatically while the message moving on the mesh network, that means the data no need to pass through all the points before reach to destination, it save many times for transaction the data. Mesh network is a network which is not easy to interruption by connection problem as there have many possible patterns that can use. When one node failure to connect, mesh network will find another way to reach the destination easily. Mesh network separate to two similar types: Full mesh and Partial mesh. Full mesh which every node will connect to each other so the network can provide best redundancy function. Once one of the nodes breakdowns, connection between the networks will be stronger under full mesh network because there have more possible route to reach to destination. Because of more wires need, so full mesh network is expensive than partial mesh network and it may also affect the set up procedure because of the complexity. For the economical reasons, some of the company will prefer to use the partial mesh network. In partial mesh network, devices are only connects to a subsection node instead of all nodes. This may affect the entire network once the connection have problem because it only have one or two ways to reach the destination point. Although the communication between the networks is not as strong as full mesh network, but the cost is cheaper than it, so nowadays partial mesh network is more popular than full mesh network. (The image of the network dictionary 2004) Physical communication media is a path that can let the electronic data move from one computer to another. And now will going to describe different physical communication media, for example Twisted-Pair cable, Coaxial Cable and Fiber-optic cable. The first cable we are going to talk about is Twisted-Pair cable. Twisted-pair cable which can be subdivided as unshielded twisted pair (UTP) and shielded twisted pair (STP) (Bruce A Hallberg 2005). Both UTP and STP have eight separate brown metal wires and cover by insulate material. Besides, each pair of wires was wound to each other. UTP and STP not only have similar structure and also have similar transmission technology. Even though STP has a better protection interface and quality than UTP, but it cost more expensive and not easy to install. Using Twisted-pair cables advantage is its size is smaller than others so that it will easy to install and it cost cheaper than Coaxial cable and Fiber-optic cable. On the other hand, the transmission signal is shorter than other communication media and the coverage area is only 100 meters. Another cable we are going to talk about is Coaxial Cable. Coaxial cable is cover by 4 layers: copper wire, insulation, copper mesh and cable jacket. Coaxial cable can aid 10-100 Mbps and it coverage 500 meters. (Scribd n.d.) The advantage of Coaxial Cable is it can run for a long distance between network but use less power. The cost of Coaxial cable is cheaper than Fiber-optic cable and because of it use for many years, so it will be more popular. However, the size of Coaxial Cable not as thin as Twisted-pair cable, so it will be difficult to install and relatively the set up fee will be higher than Twisted-pair cable. The last one we have to talk about is Fiber-Optic cable. Fiber-Optic cable is made by narrow core and insulates material. It use the lights to transmission the date. Most of the corporate network will use Fiber-optic cable as back bones to connect different network. The advantage of Fiber-optic cable is it has a higher data speed and the higher bandwidth is good for future development. But Fiber-optic cable is not quite flexible as it cannot curve, so it will be more difficult to install and the cost is the most expensive one. Different computers have its own different purpose, we are going to compare Microcomputers, Laptop computers, Minicomputers, Mainframe computers and Supercomputers size, speed, processing capabilities, price and how many users can use at the same time. Types of computers Microcomputers Laptop computers Minicomputers Mainframe computers Supercomputer Size Fits on desk Small and conveyable Size in between microcomputers and mainframe computers Partial room of apparatus Full room of apparatus Speed Up to 400 million Up to 400 million Thousands to millions Millions Millions to billions Processing capabilities Word process Surfing the web Database management Calculations Email function Word process Surfing the web Database management Calculations Email function Web surfing Check email Basic productivity software (Daniel J.Gansle,2010) Processing data quickly and information storage, mostly using on airline system, back or insurance company. Process very large amounts of date, such as weather forecasting and government. Price of computers From $2500 up to $17000 From $2500-up to $23000 From $5000-$15000 $300,000- several million dollars Several million dollars and up Simultaneously connected users For individual use only For individual use only Two to four thousand Hundred to thousand Hundred to thousand

Free Essays - The Depiction of Black Men in Alice Walkers Color Purple :: Color Purple Essays
Depiction of Black Men in The Color Purple Several critics claim Alice Walker's depiction of men is too harsh and too one-dimensional, but based on what I have read in The Color Purple, I cannot agree. Celie is a woman who has been negatively affected by men her whole life. Whether it was her stepfather throughout her childhood or her husband, Mr. _____, during her 20s, men made her life miserable. The harsh depiction of men is accurate based on the way Celie's stepfather and Mr. _____ treated her. Celie's stepfather mistreated her in such a way that an accurate depiction was made. When Celie's mother became ill and unable to satisfy her husband, he told Celie to fulfill her mother's job. When Celie cried because of the pain, her stepfather said, "you better shut up and git used to it"(3). To assure himself that no one would find out about his secret he told Celie "you better not never tell nobody but God it'd kill your mammy"(1) and told Mr._____ "she tell lies"(9). As a result, when Celie's mother passed away, she felt that she killed her mother, when in fact her mother was terminally ill. After two pregnancies, Celie was unable to produce anymore children because her father injured her reproductive system. The children Celie had, her stepfather took them away from her, while in her heart she yearned to find them even years later. Celie's stepfather degraded her and always wanted to keep her self-esteem low by constantly telling her "she is a bad influence on my o ther girls...she ugly don't even look like she kin to Nettie...she aint smart either"(9). After Celie got married, the way men treated her did not change too much. Celie got beaten in the same manor Mr. _____ beat the children, but only because she was his wife. Mr. _____'s children not wanting a new mother created a bad situation between them and Celie. The oldest boy threw a rock at Celie's head that burst open her head, the girls cry, scream, and curse and all Mr. _____ said was to not do it. Mr. _____ only married Celie to have someone to cook, clean, work, take care of the children and sleep with.

The Suffrage Movement - 1320 Words
Over the past century, Virginia and the United States have encountered a number of drastic historical changes. As both men and women had the right to cast a vote in the most recent election, a little less than a century ago women did not have to right to vote. It was not until women throughout the United States came together to spark a suffrage movement that lead to congress passing the Nineteenth Amendment of the United States Constitution which provided women with the right to vote. The suffrage movement within the state of Virginia began in the year of 1870. Despite determined efforts, the earliest movement for womanââ¬â¢s suffrage in Virginia was not very successful. On November 27, 1909, a small group of writers, artists, physicians,â⬠¦show more contentâ⬠¦In Virginia however, the ESL was facing a problem because they did not have the finances or organizational tools to fully implement the NAWSOââ¬â¢s policies. Since Virginiaââ¬â¢s ESL was not fully aligned with it parent organization from the beginning, they received very little assistance from the parent organization. Although the organization was not progressing, they never gave up on the suffrage campaign and by 1911, they established a state headquarters and increased their efforts to spread the suffrage movement throughout the commonwealth. Virginia suffragists first supported conventional gender stereotypes that women belonged in the house rather than supporting their reform on sexual equality. The president of Virginiaââ¬â¢s ESL chose to implement this particular strategy to avoid challenging the status quo which would provoke more opposition. However, as time progressed, suffragists of Virginia shifted from acceptance of traditional gender roles, towards supporting the need of female equality. As the group became aware of womenââ¬â¢s legal, economic, and social disabilities, their interests and their events began to incorporate an agenda that consisted of strong feminists components.
