Problem Based Learning as an Effective Tool for Teaching Computer Network Design Overview : In this paper we discussed about challenges that are faced in teaching computer network design using problem based learning as an effective tool. Here we discussed, where it has been introduced first and the techniques that are used in teaching computer network design. A two threaded approach is used make it more user friendly. Also several modules has been introduced to decrease the distance between industry and class room. Introduction: M.Sc degree in networks and data telecommunications is first started by University of Salford, Salford, Greater Manchester, UK in October 1990.This course has a recruitment grew of 20 students annually in its early launch and has gradually increased with high intake of 43 full time students during 1999-2000 academic year. This course is introduced mainly because the usage of modern computer networking technology is using most business organizations. Even personal computer and Internet usage also increased. Network Architecture and Design: A two threaded approach is used for effective teaching of this subject. The two threads that are involved are Lecture thread and PBL thread. In lecture thread we have theoretical understanding of network operation and performance ,various topics that are involved in lecture thread are network design principles, LAN design, Multi-site networks, connection to the internet, Managing ,protecting, sizing and understanding of network applications. The lecture thread comprised of 20hours of lectures and 4 hours of tutorials .The total thread is assessed to written examination of 80%.The other thread is PBL(prob0lem based l... ... middle of paper ... ...ssions. Each block has a fixed number of tokens, it writes cache block when processor has block token. When we compare different protocols, token protocol is effective than other two protocols. Parallelized model is programmed with certain basic functions. Conclusion: From the work gone through this paper token protocols gives better performance than directory protocols. With our investigation we can say that multithreaded versions of network faces problems with workloads and causes low exploitation in instruction level parallelism.

The Open Systems Interconnection (OSI) reference model is essential to the world of computer networking. The model was created in 1977 by the International Standards Committee, in response to a difficulty that was facing computer networkers at the time (Shelly, Cashman, and Serwatka 142). In order to understand the difficulty, one must first realize that computer networks consist of computer hardware, the software that is to be used in conjunction with this hardware, and the medium (such as wiring or cabling) that will interconnect the computing devices that are in the network. The computer networker’s job is to determine which hardware, software, and medium types will create the network that will best suit his client’s needs. Then, the networker must combine these elements into a functional system of interconnected computers (Fortino and Villeneuve 112). It was in attempting this latter task that the computer networker of the late 1970s often found himself in a pickle. The problem was that each vendor of computing equipment had developed his own unique set of products; products that were incompatible with the products of other vendors. This incompatibility made it very difficult for a computer networker to combine the various network components into an operational computer network (Stamper 27).
In addressing the problem, the proposed research will use the case study method to examine the plan, design, and implementation of WLAN technologies at Berean. At present, the non-wireless local area network (LAN) technologies employed by Berean include 10/100BaseT Ethernet at each desktop. Ethernet ports at the desktop are switch connected to an Asynchronous Transfer Mode (ATM) T1 backbone. Berean¡¦s one remote facility connects to the network using switched Frame Relay services along with Internet Virtual Private Network (VPN) connections.
In order to transfer data between layers, a bitstream is split into frames containing the frames source and destination information. Errors can occur during transmission of frames which are rectified using a suitable protocol. Frames are transferred between LAN devices by the data link layer. A frame contains a header which includes the source and destination address of the frame. Frames are delivered using...
In conclusion, this research has established that development of the TCP / IP protocol was a major step in improving communication between systems. It provided many applications which run on the protocol and thus providing many services that were not available before. It is therefore important to make use of these services in order to provide quality communication.
Some protocols are used in conjunction with each other to exchange data between computers. These protocols are called protocol stacks, or a protocol suite. The two most common examples of protocol stacks are TCP/IP and IPX/SPX. In the example of TCP/IP, the TCP prot...
With the emergence of the Ethernet LAN (Local Area Network) introduced in the early 1970s by Xerox, the telecommunications world has welcomed this newfound gift with open arms. Since communications is such a vital aspect of all businesses these days, proper acquaintance with this marvelous technology can greatly enhance your company's productivity and efficiency. In this paper, we will reflect into the many different characteristics of media that the LANs are based upon and compare/contrast these different medias.
Performance can be measured by the consumption of bandwidth and the flow of the traffic, throughput, data latency or delay time, packet loss and retransmission of data. Throughput is the amount of traffic a network can carry at any one time, the higher the bit rate, the faster files transfer. If there is a lack ...
From the protocol operation perspective, the existing protocols can be classified into negotiation based, query based, QoS based, multipath based and coherent-based protocols.
“Network Administrators are often responsible for keeping an organization 's network up to date and running smoothly” (7). Network Administrators can often identify problems and hiccups in the networking environment and create solutions to fix them. Today there are a lot of different organizations that use computers and networking as a way to stimulate the company 's growth and as a result it is essential to have someone who can identify and fix any problems as they rise. Network administrators often are expected to have great oral and written communication skills, as well as keep organized, and have prior experience in the field (8). For many jobs Network administrators are required to have a bachelor 's degree in Computer science as
It is a well-known fact that educators are always looking for new and improved ways to educate their students. It’s also safe to bet that throughout your personal education the methods that teachers were teaching varied from class to class, they might even have varied substantially. Take a moment to think about the way students learn best, whether it be hands-on learning or by reading from a text book. Nevertheless, everyone learns differently and because of this, educators must continually reevaluate the way they are teaching their students. One of the more popular ways of teaching students is referred to as problem-based learning. If you are not familiar with the term, according Zeng Furong, Deng Guangtong, Zhao Wang, and Liu Longfei problem-based
Learning model can dedefinisikan as a conceptual framework that depicts the procedure of organizing systematic learning experience to achieve a certain goal belejar, and serves as a guide for instructional designers and teachers in planning and implementing learning activities (Siberman, 2005). Problem based Learning provides active learning, independent, and self-contained, so as to produce students who are capable of independent self study continuing for life. In a model of learning problem-based learning class more lively atmosphere deiigan discussion, debate, controversy clan, greater student curiosity, problem based learning is a teaching method that is motivating students to achieve academic success.
Problem Based learning (PBL) can be defined as the method of active learning in a classroom where the students are divided into a small group (6 to 10 students) and they’ll be given a task or problem that will trigger and motivate them in the learning process. In this situation, there’s no authorities way nevertheless it will create a great emphasis on group work, self-directed learning, reflection and development learning. The lecturer must act as their facilitator or a metacognitive person in order to guide them in the way to solve the problem given (Schmidt, 1983).
I have decided to research into Networking as my individual assignment for CP2099, because I am interested in setting up networks, as I already have set up my own small network at home. I also want to find out some of the advantages and disadvantages of the different types of networks.
In the computer world, networks are the primary means of inter-computer communications. The building and maintenance of a network is the responsibility of the network manager. The network manager must have the expertise to design and implement an appropriate network for his client. The proper design of a network is based on more than a few principles. However, the job of the network manager encompasses more than simply building a useable network, although that is the end result.
