, token ring and FIDDI, and wireless, including advantages and disadvantages. Network topology connects pairs of nodes of a network using patterns of links. Mesh Topology Mesh topology connects each device in a network to every other device in the network. Some advantages of a mesh topology are that it can work over a long distance, it is reliable, and it provides redundancy and it one device fails the backup device can take over the loss data. Disadvantages of mesh are that is complicate and expensive. Bus Topology A bus topology connects a workstation along an open cable or backbone. It is usually connected by an Ethernet cable. Advantages that are listed are that installation and administration is low cost, it is easier to configure and easier to expand on and connect to. Disadvantages that are listed include, limitations, difficulty troubleshooting, if a problem occurs on the backbone the entire network would go down. Ring Topology A ring topology is when two or more nodes are connected to a workstation to create a ring. Data is sent around the loop in one direction. Advantages of a ring topology includes equal access to all workstations, each node on the ring acts as a repeater, and usage of coaxial cables that creates the ring allows the service to be much faster. Disadvantages includes difficulty troubleshooting, if one connection fails it is hard to determine where the problem, reconfiguring of a ring topology will shut down the network. Ring topology is often the most expensive within topology. Star Topology In a star topology all devices are connected to a central hub. A star topology is wired as a star but handles network traffic as a ring. Advantages and disadvantages of a star topology include easy implementation, well for temporary networks, failure to a non central node will not have major effects on the network, maintenance cost is higher, failure to the central nodes can disable the entire network, and difficult installation. I will now explain some terminology associated with network architecture. The network architecture refers to its overall structure (Tomsho, Tittel, Johnson, 2004 pg. 241). I will explain the different network architecture including advantages and disadvantages. Ethernet Wikipedia (2006) defines Ethernet as a framed based computer networking technology for local area networks. Ethernet is mostly standardized as IEE 802.3. Some of its advantages include easy installation and low cost. It supports man different kinds of networking media. Token Ring The token ring architecture was developed as an IEEE specification 802.5. Wikipedia (2006) states token rings are organized in a ring topology with data being transmitted from one ring station to the next with a control circulating around the ring controlling access. Advantages are fast, reliable transport, but are cable as a star. Disadvantages include being very expensive, difficult troubleshooting. FDDI FIDDI stands for Fiber Distributed Data Interface. FDDI uses the token passing channel access method using dual counter-routing rings for redundancy. FDDI advantages are it has high security, very fast, reliable and covers great long distance and disadvantages are that it is very expensive and difficult to install. Wireless Webopedia defines wireless network as a method of communication that uses low powered radio waves to transmit data between drives. Advantages of wireless network are a wireless connection does not have to search for a hub, easy accessibility and set up is fast, less expensive to installed than a wired network, it is convenient, and great for mobility. Disadvantages of a wireless network are less security than a wired network, decrease bandwidth, and file transfer is slow. OSI Model and TCP/IP Open System Interconnection or OSI Model is a standard reference model for communication between two end users in a network. Transmission control protocol is one of main protocols in TCP/IP network. TCP enables tow host to establish a connection and exchange streams of data (Webopedia, 2006). Internet protocol is the second protocol in the TCP/IP network. In the OSI model, TCP corresponds with layer two which is the transport layer and IP corresponds with the layer three or the network layer. TCP transport is used to deliver data across the network. IP is responsible for routing and directing data from one network to another. . References Juipterweb (2006). Definition.

ABA Essay Response - The Many Benefits Of Having A Sample

ABA Essay Response - The Many Benefits Of Having A SampleA sample of an ABA essay response is a common element to many studies, which aim to examine the effects of instruction on the specific academic needs of individuals. A student's grade can be influenced by a variety of factors, which include the student's true or perceived ability, his or her thought process and style, as well as the methods that are used to motivate him or her to complete the assignment.An ABA instructor will likely begin the class by presenting the average score of students in previous years, as well as the average score from those who enrolled for the upcoming year. This could be one of the reasons why an instructor may want to collect a sample of ABA essay response from the class before the semester begins. Through this, instructors can determine how much of an effect the fact that the students were receiving a test score influenced their behavior.Having a sample of ABA essay response from the class will hel p the instructor prepare for class discussions, as well as figure out the types of questions that he or she would like to ask during the lessons. With the presence of this, it will become easier for the instructor to choose the correct questions to ask his or her students.By knowing the model for an example essay response, the instructor can also find out what he or she needs to improve upon in order to make the best possible presentation for the class. This will help the instructor to achieve this goal, as he or she will be able to recognize how certain ideas or points could be omitted. It can also be helpful for the instructor to determine whether there are any instances where the students really struggled in the course.There are some students who may struggle when reading information on the internet, while other students may have trouble finding information about the topic. Students may take just as long as other students do when searching for information, but this should not be an excuse for them to give an incomplete essay. When the instructor has a sample of an ABA essay response, he or she can determine whether his or her student is easily distracted or overwhelmed when presented with multiple types of information.Another way that the instructor can use a sample of an ABA essay response is for other purposes. It can be utilized as a short report, which can then be used for the test. The instructor will only need to have an ABA essay response to read the sample, while his or her students will need to answer the essay questions on their own.In addition to these two benefits, a sample of an ABA essay response can also be used to determine the topics that the students feel the most comfortable with. The majority of students will prefer to write about topics that interest them, since this is what will provide them with a unique perspective. This is also one of the reasons why an instructor will want to get a sample of an ABA essay response, as he or she can determine which topics are preferred by his or her students.When it comes to obtaining a sample of an ABA response, an instructor will be able to find that the responses come in many different formats. Some of these responses are simply found online, while others can also be acquired from class notes. By getting this type of response, it will allow an instructor to determine how well he or she can communicate information to the students, as well as to gain insight on his or her own abilities.
