Questions And Answers

Previous studies have shown that motivating students to learn about local area network (LAN) design can be difficult when presented in the traditional lecture format. To overcome this problem, a Web-based tool (“WebLan-Designer”) was developed as an aid in teaching and learning of LAN design at the introductory level. A WebLan-Designer provides a set of learning resources (tutorials, quizzes, network modeling, network design scenarios, key terms and definitions, and review questions and answers) and assists undergraduate students in learning the basics of both wired and wireless LAN design. The tool is Internet-based and can be accessed at any time so that students can study LAN design at their own pace and convenience. This flexible learning approach contributes positively to distance education and e-learning. The effectiveness of WebLan-Designer is evaluated both formally and informally; positive student and peer feedback indicates that the design and implementation of the tool has been successful and that using WebLan-Designer may have a positive impact on student learning and comprehension.

Information and Communication Technology (ICT) is a very important requirement in the implementation of education. Becoming a necessity for SMAN 4 Praya as an upper secondary educational institution to build computer network technology considering the complexity of the problems faced in the administrative system as well as the teaching and learning process. ICTs need to be well-designed to ensure that resources can be utilized optimally and mission vision can be achieved as expected. The design of computer networks at SMAN 4 Praya uses the Network Development Life Cycle (NDLC) approaches as a development method, covering a number of stages analysis, design, prototype simulation, implementation, monitoring and management. The process of analysis is divided into several processes, namely user needs analysis, device requirement analysis (hardware, software, brainware), network needs analysis, feasibility analysis (feasibility of infrastructure and human resource feasibility), and through network topology analysis by designing architecture and computer network design. Network Design Local Area Network (LAN) and Wireless Fidelity (WiFi) based on Mikrotik RouterOS. Implementation of the use of Mikroutik RouterOS on the Internet network SMAN 4 Praya can provide effective and optimal results to divide the bandwidth of each client as as reserved, and allows administrators in managing the network to remain stable and provide maximum results.

A tms320dm642 and wireless fidelity based fire monitoring robot is designed. Flame features, both static and dynamic detecting algorithm, combine with long wave infrared (LWIR) is equipped to achieve the goal of monitoring fire. When the suspected fire event happens, Fire warning message will be sent to remote terminal through the wireless LAN automatically. Infrared image of the fire can be transmitted through the wireless network under the control of remote terminal. As LWIR camera can even look through the dense smoke of fire, fire source will be located accurately, rescuing and fire fighting work will carry on better and with less injury.

Due to the problem of network structure, security, redundant path in traditional network, this can be solved by Virtual Local Area Network (VLAN) technology. As the network laboratory in colleges and universities is not perfect because of high cost, a virtual simulation tools named Packet Tracer has been introduced to computer network experimental curriculum, this paper put forwards the detail design scheme by the example of VLAN with three switches, and provides the experiment and theoretical analysis and simulation verification .The practice has proved this method not only deepens students comprehension of network, but also cultivates the students' actual comprehensive ability.

Modernization causes the examination process in some educational institutions that are usually done conventionally now start to change to CBT (Computer Based Test). At STMIK Atma Luhur, CBT in the form of a coding test carried out on a computer laboratory was felt to be not effective enough due to a short correction time, as well as the possibility of lossing the students work due to sudden power failure. Collection of jobs using an LAN (Local Area Network) intranet network can not be realized due to the difficult network configuration and requires not a small cost. One solution that can be offered in overcoming the above problem is to create a web-based exam application that is connected to a Wireless Local Area Network (WLAN) intranet network. The system development model and tools used in this study are prototype models and UML (Unified Modeling Language). The proposed application is effective in facilitating and accelerating the process of collecting student answer files from several client computers to a server computer. In addition, the usage of the proposed application allows the lecturer not to correct students' answers in a hurry, so that the scores that are truly objective and can be accounted for are obtained.

Identity Cards

In a wired local area network (LAN), the network ports and cables are mostly contained inside a building. Therefore, a hacker must defeat physical security measures, such as security personnel, identity cards, and door locks, to be able to physically access the LAN. However, the penetration capability of electromagnetic waves exposes the data transmission medium of a wireless LAN (WLAN) to potential intruders (Potter & Fleck, 2003). The fast development of wireless technologies implies that wireless communications will become ubiquitous in homes, offices, and enterprises. In order to conserve power and frequency spectrum, the wireless device computation overhead is most often reduced. The conventional security design thus uses smaller keys, weak message integrity protocols, and weak or one-way authentication protocols (Hardjono & Dondeti, 2005). WLAN security thus requires a more reliable protection of data communication between WLAN units and strong access management mechanisms.
